3 Configuration Methods Chapter 3 Introduction This chapter provides information about the different methods you can use to configure the IOLAN. Before you can configure the IOLAN, you must assign an IP address to the IOLAN. See the Chapter 4, Getting Started on page 65 to find out how to assign an IP address to the IOLAN. Once an IP address is assigned to the IOLAN, you can use any of the configuration methods to: z Configure users. z Configure IOLAN server parameters.
Configuration Methods Overview Configuration Methods Overview Some of the IOLAN configuration methods have the capability of configuring an IP address, which is the first required configuration step for a new IOLAN. Once the IOLAN has been assigned an IP address, any of the configuration methods can be used to configure the IOLAN.
Easy Config Wizard Easy Config Wizard The Easy Config Wizard is a configuration wizard that will configure all the serial ports on your IOLAN to one of the following: z Console Management z TruePort (Virtual COM Port) z TCP Sockets (Raw TCP) z Terminal z Printer (not supported on DS1/TS2 models) z Serial Tunneling You can launch the Easy Config Wizard from the Perle website or from the installation CD-ROM.
DeviceManager DeviceManager Overview The DeviceManager is a Windows-based application that can be used to connect to the IOLAN to actively manage and configure it or can create new IOLAN configurations offline. See Chapter 5, Using DeviceManager and WebManager on page 73 for information on configuring/managing the IOLAN with DeviceManager. Access Platforms The DeviceManager can be run from Windows 98/NT/2000/ME/Server 2003/XP/Server 2008/Vista.
DeviceManager All discovered IOLANs will be displayed on the list along with their name and IP address. When a new IOLAN is discovered on the network, that has not yet been assigned an IP address, it will be displayed with an IP Address of Not Configured. To configure the IP address, click on the IOLAN and then click the Assign IP button. Choose the method you want to use to assign an IP address to the IOLAN: z Type in the IP address that you want to assign to this IOLAN.

If double-click on option that is next to a folder, more navigation are displayed when you click on it: Navigation Tabs The Network folder contains two configuration options, IP Address and Advanced.
WebManager WebManager Overview The WebManager is a web-browser based method of configuring/managing the IOLAN. It follows the same design as the DeviceManager, so it is easy to switch between the WebManager and DeviceManager when configuring your IOLAN. See Chapter 5, Using DeviceManager and WebManager on page 73 for information on configuring/managing the IOLAN with DeviceManager. Access Platforms You can access the IOLAN through WebManager from any system that can run a web browser.
WebManager Connecting to the IOLAN Using WebManager Before you can connect to the IOLAN using WebManager, the IOLAN must already be configured with a known IP address; see Setting Up the Network on page 66 to configure an IP address on your IOLAN. To connect to the IOLAN through the WebManager: 1. Open your web browser and type in the IP address of the IOLAN that you want to manage/configure and press Enter; for example: http://123.123.123.123. 2.
WebManager Using WebManager After you have successfully logged into WebManager, you will see the following: Navigation Tree System Information You navigate through the different configuration windows by selecting an option in the left-hand navigation tree. When you click on an option that is under a folder, more navigation options are displayed: Navigation Tabs The Network folder contains two configuration options, IP Address and Advanced.
Command Line Interface Command Line Interface Overview The Command Line Interface (CLI) is a command line option for IOLAN configuration/management. See the Command Line Interface Reference Guide for a full breakdown of all the CLI commands and their functionality. Access Platforms The CLI is accessed by any application that supports a Telnet or SSH session to the IOLAN’s IP address, such as Putty, SecureCRT, or from a command prompt.
Menu Through the Serial Port To connect to the IOLAN through the serial port to configure/manage it using the CLI (or Menu), see Using a Direct Serial Connection to Specify an IP Address on page 67. After you have established a connection to the IOLAN, you will get a Login: prompt. You can login as the admin user or as a user with Admin Level rights.

You will be asked to enter a terminal type, and then you will see the following Menu: To navigate through the Menu options, do the following: 54 1. Highlight a Menu option by using the keyboard up and down arrows to navigate the list. 2.
DHCP/BOOTP DHCP/BOOTP Overview Several IOLAN parameters can be configured through a DHCP/BOOTP server during the IOLAN bootup. This is particularly useful for configuring multiple IOLANs. Not all configuration parameters are supported in the DHCP/BOOTP configuration (see DHCP/BOOTP Parameters on page 56 for supported configuration parameters), so you will need to use another configuration method, such as DeviceManager, WebManager or CLI, to complete the configuration.
DHCP/BOOTP DHCP/BOOTP Parameters The following parameters can be set in the DHCP/BOOTP bootp file: z SW_FILE—The full path, pre-fixed by hostname/IP address (IPv4 or IPv6), and file name of the firmware update. z CONFIG_FILE—The full path, pre-fixed by hostname/IP address (IPv4 or IPv6), and file name of the configuration file. z GUI_ACCESS—Access to the IOLAN from the HTTP or HTTPS WebManager. Values are on or off. z AUTH_TYPE—The authentication method(s) employed by the IOLAN for all users.
SNMP SNMP Overview The IOLAN supports configuration and management through SNMP. SNMP Management tools (SNMP client/MIB browser software) can be used to set IOLAN configuration parameters and/or view IOLAN statistics. Before you can configure/manage the IOLAN using SNMP, you need to set the IOLAN IP address and configure a read-write user for SNMP version 3 or a community for SNMP version 1 or 2.
SNMP Using the SNMP MIB After you have successfully connected to the IOLAN through your SNMP Management tool or MIB browser, expand the PERLE-IOLAN-SDS-MIB folder to see the IOLAN’s parameter folders. Below is an example of the configurable parameters under the ServicesInfo folder. The first variable in each folder is the Status variable, for example, serviceStatus.
IOLAN+ Interface IOLAN+ Interface Overview For environments that have both IOLAN and IOLAN+ models or for users who prefer to configure using the IOLAN+ Menu or CLI, the IOLAN+ user interface is available. The IOLAN+ interface is supported on all IOLAN SDS, SCS, and STS models up to and including 16 serial ports. Access Platforms The Menu is accessed by any application that supports a Telnet or SSH session to the IOLAN’s IP address, such as Putty, SecureCRT, or from a command prompt.

4 Getting Started Chapter 4 Introduction There are several different configuration methods available to configure the IOLAN (see Chapter 3, Configuration Methods on page 43 for more information). This chapter describes the three main minimal configuration requirements for the IOLAN through either Easy Config Wizard (cannot configure users using this method), DeviceManager, or WebManager: 1. Setting up the network—This minimally consists of configuring an IP address or enabling DHCP/BOOTP.
Setting Up the Network z TruePort (Virtual COM Port)—Allows a networked system to communicate with your serial device through a virtual COM or TTY port, using the Perle TruePort software. z TCP Sockets (Raw TCP)—Allows hosts on the network to communicate with a serial device that requires raw data throughput (such as a printer or card reader) connected to the IOLAN serial port. z Terminal—Allows a terminal device to connect to a specified host on the network through a serial port on the IOLAN.
Setting Up the Network 10. Expand the Server Configuration folder and select Server. Verify the IP address configuration. You should also enter a name in the Server Name field to make the IOLAN easily identifiable. 11. To make your edits take effect, you need to download the new configuration file and then reboot the IOLAN. Download the configuration file to the IOLAN by selecting Tools, Download Configuration to Unit or click the Download All Changes button. 12.
Setting Up the Network Using a Direct Serial Connection to Enable BOOTP/DHCP If you are using BOOTP, you need to add an entry in the BOOTP server for the IOLAN that associates the MAC address (found on the back of the IOLAN) and the IP address that you want to assign to the IOLAN. After you have made the MAC address/IP address association for BOOTP, use the following directions for BOOTP or DHCP.
Setting Up the Network Using ARP-Ping You can use the ARP-Ping (Address Resolution Protocol) method to temporarily assign an IP address and connect to your IOLAN to assign a permanent IP address. To use ARP-Ping to temporarily assign an IP address: 1. From a local UNIX/Linux host, type the following at the system command shell prompt: arp -s a.b.c.d aa:bb:cc:dd:ee:ff On a Windows® 98 or newer system, type the following at the command prompt: arp -s a.b.c.d aa-bb-cc-dd-ee-ff (where a.b.c.
Setting Up the Serial Port(s) Setting Up the Serial Port(s) The DeviceManager and WebManager have the following serial port profiles that will simplify serial port setup: 70 z Console Management—The Console Management profile configures a serial port to provide network access to a console or administrative port. This profile sets up a serial port to support a TCP socket that listens for a Telnet or SSH connection from the network.
Setting Up the Serial Port(s) z Virtual Modem—The Virtual Modem (Vmodem) profile configures a serial port to simulate a modem. When the serial device connected to the IOLAN initiates a modem connection, the IOLAN starts up a TCP connection to another IOLAN configured with a Virtual Modem serial port or to a host running a TCP application. z Control Signal I/O—The Control Signal I/O profile enables the use of the EIA-232 serial port signal pins to be used as assigned Digital Inputs or Digital Outputs.
Setting Up Users Setting Up Users When you have a user who is accessing a device connected to a serial port from the network or who is accessing the network from a device connected to a serial port through the IOLAN, you can create a user account and configure the user’s access privileges.
5 Using DeviceManager and WebManager Chapter 5 Introduction The DeviceManager and WebManager IOLAN managers have been designed to be very similar to use. DeviceManager is a Windows-based application and WebManager is a browser-based application. Both options use the IOLAN’s IP address to access the IOLAN; the DeviceManager can be used to assign an IP address to a new IOLAN and the WebManager requires that the IOLAN already have an IP address before it can be used to configure the IOLAN.
Navigating DeviceManager/WebManager Navigating DeviceManager/WebManager The DeviceManager and WebManager have very similar navigation methods. The left-hand side of the manager is the navigation tree and the center is the configuration area. The DeviceManager has menu and quick access buttons, whereas the WebManager has system information and some navigation options on the far right-hand side. DeviceManager The DeviceManager uses a folder/page navigation tree.
Navigating DeviceManager/WebManager WebManager The WebManager uses a expandable/collapsible buttons with folders and pages for the navigation tree. You can expand the buttons to view the folders and pages to see the available configuration options. When you access a configuration page, you can often navigate the tabs in the configuration area to access all of the configuration options.
Using DeviceManager to Connect to the IOLAN Using DeviceManager to Connect to the IOLAN DeviceManager can connect to existing IOLANs or assign an IP address to a new IOLAN. Whenever you connect to the IOLAN through the DeviceManager, you connect as the Admin user and must supply the password for the Admin user.

Adding/Editing Users Enable VJ Compression Used for User Service PPP or SLIP, determines whether Van Jacobsen Compression is used on the link. VJ compression is a means of reducing the standard TCP/IP header from 40 octets to approximately 5 octets. This gives a significant performance improvement, particularly when interactive applications are being used. For example, when the user is typing, a single character can be transmitted and thus have the overhead of the full TCP/IP header.
Adding/Editing Users Session Timeout The amount of time, in seconds, before the IOLAN forcibly closes a user’s session (connection). The default value is 0 (zero), meaning that the session timer will not expire (the session is open permanently, or until the user logs out). The User Session Timeout will override all other Serial Port Session Timeout parameters.
Adding/Editing Users Sessions Tab Overview The Sessions tab is used to configure specific connections for users who are accessing the network through the IOLAN’s serial port. Functionality Users who have successfully logged into the IOLAN (User Service set to DSprompt) can start up to four login sessions on network hosts.

I/O UDP I/O UDP Industrial applications often monitor the status of I/O devices such as sensors, alarms, relays, etc. by polling for I/O data. The IOLAN’s I/O UDP feature can help to minimize network traffic by broadcasting I/O status to industrial applications on specified intervals, providing I/O status in a timely manner. The IOLAN’s I/O UDP broadcast feature sends the status of attached I/O devices to defined hosts on the network.
I/O UDP Analog Section The Analog Section of the UDP packet is comprised of I/O data for each enabled Analog channel. Note: If the IOLAN I/O model does not support Analog channels, the Analog Channel Data subsection of the Analog Section will NOT be present in the UDP packet.
I/O UDP Digital/Relay Section The Digital/Relay Section of the UDP packet provides the status of Digital and Relay channels. The data for the status of each channel is represented by 1 byte, with each bit representing a channel (least significant bit format). Note: The Digital/Relay Channel Data subsection is present in the UDP packet regardless of whether or not the IOLAN model supports Digital/Relay channels.
I/O Modbus Slave UDP Unicast Example For an example of the I/O UDP unicast, see the sample program, ioudpbcast.c, found on your CD-ROM. I/O Modbus Slave If you have a Modbus serial or TCP application, it can access I/O connected to the IOLAN when the I/O Global Modbus Slave is enabled. You must supply a unique UID for the IOLAN, as it will act as a Modbus Slave. There are three ways your Modbus Application can connect to the IOLAN to access I/O.
Modbus I/O Access Modbus TCP Application If you have a Modbus RTU or Modbus ASCII program, you can access the I/O by connecting to the IOLAN over the network. UID: 15 Power perle Network IOLAN PC running a Modbus RTU or ASCII Application I/O Digital Output Modbus I/O Access The section defines the function codes and registers you will need to access the I/O through Modbus TCP, Modbus serial, or Modbus serial/TruePort.

TruePort I/O TruePort I/O You can see a sample API I/O over TruePort program called ioapiotp.c on the CD-ROM. TruePort/Modbus Combination If you have a Modbus serial application running on a PC that is connected to a network, you can use TruePort as a virtual serial connection to communicate with the IOLAN over the network to access I/O data.
TruePort I/O API Over TruePort Only If you have a custom application that talks to a serial port, you can use TruePort as a virtual serial port to communicate with the IOLAN over the network to access I/O data using the Perle API. You also have the option of enabling SSL as a security option to encrypt the data that is communicated between the IOLAN and the host machine (SSL/TLS must be configured in the Server settings and on the TruePort host).
Accessing I/O Data Via TruePort Accessing I/O Data Via TruePort Introduction Analog and Digital I/O data, as well as output control, can be accessed in several ways. To have access from an application running on a workstation or server, the I/O Applications Program Interface (API) provided within Trueport can be used. This API uses a command/response format to get or set data on each individual I/O channel register. A sample program (ioapiotp.
Accessing I/O Data Via TruePort Format of API Commands There are two groups of commands: z Get Commands—Retrieve values of the I/O channel registers z Set Commands—Set values on the I/O channel registers. Note: All commands need to be written to the COM port as a single write. I/O Channel registers are all assigned unique addresses, which need to be referenced in all of the commands. Please refer to the documentation specific you the applicable mode, for the list and addresses of all the registers.
Accessing I/O Data Via TruePort Example 1: Read the status of the first digital input (DI1) on a D2R2 unit. DI1 sensor is a coil register with the decimal value of 6145 (hex 0x1801). Request: 0x01 0x18 0x01 0x00 0x01 Response: 0x01 0x01 0x01 (Digital input 1 is active) Example 2: Read the values for the Inactive Signal Width, Active Signal Width, and Pulse count for the second digital output (DO2) on a D4 unit.
Accessing I/O Data Via TruePort Successful Response Format Byte(s) # of Bytes Value 1 1 Command code (from request). 2 2 Starting register number (see A4/T4 Registers on page 270, A4D2/A4R2 Registers on page 271, or D4/D2R2 Registers on page 272 for this value) from request. 4 2 Number of registers written. Unsuccessful Response Format Byte(s) # of Bytes Value 1 1 Command that this is a response to. If an error has been detected, the command value will have the high bit set (OR with 0x80).

When enabled, the Server Name is displayed in the IOLAN login prompt, CLI prompt, WebManager login screen, and the heading of the Menu.
Management Bootup Files Tab Field Descriptions You must have a TFTP server running on any host that you are uploading or downloading files to/from. When you specify the file path, the path must be relative to the default path set in your TFTP server software. Configure the following parameters: Firmware Host The host name or IP address of the server that contains the firmware file. If you use a host name, it must exist in the IOLAN’s host table or be resolved by DNS.
Management Message of the Day (MOTD) Tab Field Descriptions The message of the day is displayed when users log into the IOLAN through a telnet or SSH session or through WebManager or EasyPort Web. There are two ways to retrieve the message of the day to be displayed to users when they log into the IOLAN: z The message of the day file is retrieved from a TFPT server everytime a user logs into the IOLAN.
Management TFTP Tab Field Descriptions You must have a TFTP server running on any host that you are uploading or downloading files to/from. Note: TFTP file transfers send via UDP packets. When the packet delivery is interrupted for any reason and a timeout occurs, that packet is resent if the retry count allows it. Therefore, if a very large file is being transferred and is interrupted, the entire file is not resent, just the part of the file that was not received.

16 Applications Chapter 16 Introduction This chapter provides examples of how to integrate the IOLAN within different network environments or applications. Each scenario provides an example of a typical setup and describes the configuration steps to achieve the IOLAN functionality feature. Configuring Modbus This sections provides a brief overview of the steps required to configure the IOLAN for your Modbus environment.
Configuring Modbus Modbus Gateway Settings The scenarios in this section are used to illustrate how the IOLAN’s Modbus Gateway settings are incorporated into a Modbus device environment. Depending on how your Modbus Master or Slave devices are distributed, the IOLAN can act as both a Slave and Master Gateway(s) on a multiport IOLAN or as either a Slave or Master Gateway on a single port IOLAN.
Configuring Modbus Modbus Serial Port Settings Modbus Master Settings When the Modbus Masters is attached to the IOLAN’s serial port, configure that serial port to the Modbus Gateway profile acting as a Modbus Master. You must configure the Modbus TCP Slaves on the TCP/Ethernet side so the IOLAN can properly route messages, using the Modbus Slave’s UIDs, to the appropriate TCP-attached devices. Modbus Slave IP: 10.10.10.12 UID: 23 Master Gateway TCP IOLAN IP: 10.10.10.10 Modbus Slave IP: 10.10.10.
Configuring Modbus Modbus Slave Settings When you have Modbus Slaves on the serial side of the IOLAN, configure the serial port to the Modbus Gateway profile acting as a Modbus Slave. There is only one Slave Gateway in the IOLAN, so all Modbus serial Slaves must be configured uniquely for that one Slave Gateway; all serial Modbus Slaves must have unique UIDs, even if they reside on different serial ports, because they all must be configured to communicate through the one Slave Gateway.
Configuring PPP Dial On Demand Configuring PPP Dial On Demand The IOLAN can be configured to access remote networks via modems connected to the serial interface of the IOLAN. By configuring the IOLAN for the Remote Access (PPP) profile, data that is destined for the remote network will initiate a modem connection to the remote network to route the data to its appropriate destination. 172.16.0.0 PPP Local IP Addr: 195.16.20.23 PPP Remote IP Addr: 195.16.20.24 perle Network IOLAN Local Host 204.16.0.
Setting Up Printers 6. Next you need to create a gateway and destination route entry. Select Network, Advanced, and the Route List tab. For the destination, if you want the connection to be able to reach any host in the remote network, set the Type to Network and specify the network IP address and subnet/prefix bits; if you want the connection to go directly to a specific remote host, set the Type to Host and specify the host’s IP address.
Setting Up Printers Remote Printing Using RCP When setting up a serial port that accesses a printer using RCP, do the following: 1. Set the serial port to Printer and configure the Speed, Flow Control, Stop Bits, Parity, and Bits parameters so that they match the printer’s port settings. 2. Save your settings and restart the serial port. 3.
Configuring a Virtual Private Network Configuring a Virtual Private Network You can configure the IOLAN to act as a Virtual Private Network (VPN) gateway using the IPsec protocol. Any of the following scenarios can be configured using one IOLAN and a host/server running IPsec software or two IOLANs, each acting as the VPN gateway. All the examples have NAT Traversal (NAT_T) enabled, since both VPN gateways are running through routers.
Configuring a Virtual Private Network 2. Use a utility (for example, Openswan’s newhostkey/showhostkey utilities) to generate the RSA signature public key.
Configuring a Virtual Private Network Network-to-Network The following examples shows how to configure a network-to-network IPsec tunnel. This example uses the X.509 Certificate authentication method, so it includes the configuration requirements for the X.509 certificate. NAT Traversal (NAT_T) is enabled in this example (on both sides) because the VPN tunnel is going private network to public network to private network.
Configuring a Virtual Private Network 3. If the signer of the remote X.509 certificate has not already been included in the CA list file that has already been downloaded to the IOLAN, you need to add (append) the signer of the X.509 certificate to the CA list file and then download the file to the IOLAN by selecting Tools, Advanced, Keys and Certificates. In the Keys and Certificates window, select Download SSL/TLS CA and the file name and click OK.
Configuring a Virtual Private Network 2. The following window configures the Right IOLAN VPN Gateway: %defaultroute is entered for the Local IP Address because the IP address is DHCP assigned and is therefore subject to change. %any is entered for the Remote IP Address to indicate that it will accept a VPN connection from any host/network; this is necessary because the Left IOLAN VPN gateway is DHCP assigned and cannot be known.
Configuring a Virtual Private Network VPN Client-to-Network The following example shows how to configure a VPN client-to-network IPsec tunnel. In this example, the IOLAN will accept VPN connections from multiple VPN clients on private networks that want to access the public 199.24.0.0 subnetwork through the VPN gateway. NAT Traversal (NAT_T) is disabled in this example (on both sides) because the VPN tunnel is going private network to public network.

I Troubleshooting Appendix I Introduction This chapter provides information that can help resolve problems with the IOLAN. Hardware Troubleshooting The Power/Ready LED stays red after a boot. If the IOLAN Power/Ready LED is red and stays red for over 10 seconds, you have a hardware problem that might to require factory service.
Communication Issues Communication Issues General communication checks and practices are as follows: z Are your cables connected and correctly configured? If you are using EIA-232, see EIA-232 Cabling Diagrams on page 356 to verify that your cables are correctly configured. z Ping your host? If you can ping but packet loss is reported, ping another host/device on the same network. This will tell you whether the problem is specific to the host/device or general to the network.
Host Problems Host Problems Cannot access a host by name: z If using DNS or if DNS is required, ensure a nameserver is configured on your IOLAN and is accessible (ping it). z If not using DNS, verify that the host is configured in the Host Table. Check access to the host by pinging it using the host’s IP address. Cannot access a host on a local network, verify: z The network address is correct. z The subnet mask is set correctly and reflects the network configuration.
Login Problems Login Problems You cannot obtain a login on any of the serial ports z Connect via the Admin port and check the settings of the front-mounted ports; they have probably been set to a profile that does support serial connections, such as the Console Management profile (in CLI or Menu, ‘direct’ or ‘silent’ telnet/rlogin). Try setting the serial port(s) to the Terminal profile (DSlogin in CLI or Menu). You have lost or don't know your password (as Admin user).
Unknown IP Address Unknown IP Address You have already configured the IOLAN and you do know your password, and have lost, misconfigured, or don't know the IP address of the IOLAN, so you cannot obtain a successful login. z If the IOLAN resides within the local network segment, you can use DeviceManager to find the IOLAN. z You can connect directly to the serial port of the IOLAN, as explained in Using a Direct Serial Connection to Specify an IP Address on page 67.
Modem Problems Modem Problems The IOLAN is not initializing the modem. z Check your Line Service is set to SLIP or PPP. If your line service is set to any other type, the IOLAN will not initialize a modem. You will need to configure the modem manually. PPP Problems The link fails on start-up when there are remote IP addresses set for both a user (Framed IP value) and a line (Remote IP address). z Check the IP address set for the user; this is used in preference to the IP address set for a line.
SSL/TLS SSL/TLS If you are experiencing problems obtaining a successful SSL/TLS connection, you can set your Syslog Level to Notice and view the syslog for the following messages: Line not SSL enabled. Abort connection when a user who is configured for Service SSL_RAW tries to login on the serial port. The user has been configured for an SSL_RAW connection, but the line has not been configured to enable SSL.
IPv6 Issues IPv6 Issues You are not seeing the IPv6 address value when you attempt to connect to the IOLAN. Windows Vista and Server 2008 operating systems have IPv6 support already enabled, however, you will have to install IPv6 support for Windows XP. To install IPv6 support in Windows XP, do the following: 400 1. In Control Panel, double-click the Network Connections icon. 2. Double-click the Local Area Connection entry. 3.
