Control I/O Chapter 6 3. From the Major Revision pull-down menu, choose the major revision of the I/O module you want to add and click OK. The Module Properties dialog box appears. 4. In the Name field, type the name of your I/O module. 5. In the Slot field, type the slot number in which your I/O module will reside. 6. From the Comm Format pull-down menu, choose a communication format. For more information on the selection of communication formats, see Set the Requested Packet Interval (RPI) on page 88.
Chapter 6 Control I/O Select a Communication Format When configuring an I/O module, select its communication format. The chosen communication format determines the data structure for the module’s tags. Many I/O modules support different formats. Each format uses a different data structure. The chosen communication format determines: • direct or rack-optimized connection. • ownership.
Control I/O Chapter 6 Choosing a Direct or Rack-optimized Connection The Logix5000 controller uses connections to transmit I/O data. These connections can be direct connections or rack-optimized connections. Term Definition Direct connection A direct connection is a real-time, data transfer link between the controller and an I/O module. The controller maintains and monitors the connection with the I/O module.
Chapter 6 Control I/O Direct Connections For I/O Modules In this example, assume that each distributed I/O module is configured for a direct connection to the controller.
Control I/O Chapter 6 Rack-optimized Connections For I/O Modules In this example, assume that each digital I/O module is configured for a rack-optimized connection to the controller. Analog modules must be configured for direct connections.
Chapter 6 Control I/O Ownership In a Logix5000 system, modules multicast data. Therefore, multiple modules can receive the same data at the same time from a single module. When choosing a communication format, decide whether to establish an owner-controller or listen-only relationship with the module. Types of Module Ownership Owner controller The controller that creates the primary configuration and communication connection to a module.
Control I/O Chapter 6 Choosing a Type of Module Ownership If the module is an And another controller And you want to Then use this type of connection Input module Does not own the module Owner Owns the module Maintain communication with the module if it loses communication with the other controller Owner Use the same configuration as the other owner controller.
Chapter 6 Control I/O Set the Requested Packet Interval (RPI) When you configure an I/O module, you define the requested packet interval (RPI) rate for the module. Only data-producing modules require an RPI. For example, a local EtherNet/IP communication module requires no RPI because it produces no data for the system but acts only as a bridge. To set an RPI, perform this procedure. 1. Make sure the module is installed, started and connected to the controller via a serial, or other network, connection.
Control I/O Chapter 6 4. From the Requested Packet Interval (RPI) menu, select the rate at which you want data to be updated over a connection. Only set the RPI to the rate the application requires. IMPORTANT The RPI determines the number of packets per second that the module will produce on a connection. Each module can only produce a limited number of packets per second. Exceeding this limit prevents the module from opening more connections. 5. Click OK.
Chapter 6 Control I/O Access Distributed I/O I/O information is presented as a structure of multiple fields, which depends on the specific features of the I/O module. The name of the structure is based on the location of the I/O module in the system. Each I/O tag is automatically created when you configure the I/O module through the programming software. Each tag name follows this format: Location:SlotNumber:Type.MemberName.SubMemberName.
Control I/O Chapter 6 EXAMPLE 1 2 3 4 Example Module Example Tag Names (automatically created by the software) 1 Remote 1794-AENT adapter “FLEX_io_adapter” FLEX_io_adapter:I FLEX_io_adapter:I.SlotStatusBits FLEX_io_adapter:I.Data FLEX_io_adapter:O FLEX_io_adapter:O.Data 2 Remote 1794-IA16 “input_module” in slot 0 FLEX_io_adapter:0:C FLEX_io_adapter:0:C.Config FLEX_io_adapter:0:C.DelayTime_0 FLEX_io_adapter:0:C.DelayTime_1 FLEX_io_adapter:0:C.DelayTime_2 FLEX_io_adapter:0:C.
Chapter 6 Control I/O The choice of rack optimization for an I/O module creates tags as aliases for the adapter module’s tags. This logic displays the device’s tag as an alias for a the adapter module’s tag. In this example, the tag name of the adapter is in angle brackets. Tag Name of the I/O Device Tag Name of the Adapter Conveyor:2:I.0

Interlocking and Data Transfer Between Controllers Tag Guidelines for Produced or Consumed Data Chapter 7 To properly organize tags for produced or consumed data (shared data), follow these guidelines. Guidelines for the Organization of Tags Guideline Details Create the tags at the controller scope. You can share only controller-scoped tags. Use one of these data types: • To share other data types, create a user-defined data type that contains the required data.
Chapter 7 Interlocking and Data Transfer Between Controllers Connections for Produced and Consumed Tags Logix controllers can produce (broadcast) and consume (receive) system-shared tags that are sent and received via the EtherNet/IP communication module. Produced and consumed tags each require connections.
Interlocking and Data Transfer Between Controllers Chapter 7 The graphic below shows a Logix5000 controller producing a single tag for consumption by another Logix5000 controller. In this example, the producing controller uses 2 connections and every other Logix module/controller uses only 1 connection.
Chapter 7 Interlocking and Data Transfer Between Controllers Produce a Tag To produce a tag, configure the produced tag in the RSLogix 5000 project for the local (producer) controller. You do not have to configure the consumer controllers in the I/O Configuration folder of the producer controller. Configure the Produced Tag To configure the produced tag, perform this procedure. 1.

Interlocking and Data Transfer Between Controllers Guidelines for Message (MSG) Instructions Chapter 7 Follow these guidelines. MSG Instruction Guidelines Guideline Details For each MSG instruction, create a control tag. Each MSG instruction requires its own control tag. · Data type = MESSAGE · Scope = controller · The tag cannot be part of an array or a user-defined data type. Keep the source and destination data at the controller scope.
Chapter 7 Interlocking and Data Transfer Between Controllers Connections for Messages Messages transfer data to other modules, such as other controllers or operator interfaces. Each message uses one connection, regardless of how many modules are in the message path. To conserve connections, you can configure one message to read from or write to multiple modules. These connected messages can leave the connection open (cache) or close the connection when the message is done transmitting.
Chapter 7 Interlocking and Data Transfer Between Controllers Enter Message Logic To send or receive data from an EtherNet/IP module via a message, you must program a MSG instruction in the local controller’s logic.

If the target module is configured in the I/O Configuration folder of the originating controller, click Browse to select the module or manually enter the path to the target module.
Interlocking and Data Transfer Between Controllers Communicate with PLC-5 or SLC Processors Chapter 7 If the message is to a PLC-5 or SLC 500 processor and it reads or writes integers (not REALs), use a buffer of INTs in the message. Remember that: • Logix5000 controllers execute more efficiently and use less memory when working with 32-bit integers (DINTs). • PLC-5 and SLC 500 processors require 16-bit integers. • Messages require an INT buffer. • Data can be moved into or out of the buffer as needed.
Chapter 7 Interlocking and Data Transfer Between Controllers Mapping Tags A Logix5000 controller stores tag names on the controller so that other devices can read or write data without having to know physical memory locations. Many products only understand PLC/SLC data tables, so the Logix5000 controller offers a PLC/SLC mapping function that enables you to map Logix tag names to memory locations.
Interlocking and Data Transfer Between Controllers Chapter 7 This example shows how to use a buffer of INTs. EXAMPLE Read integers from a PLC-5 controller. When condition turns on, reads 16-bit integer values (INTs) and stores them in int_buffer. Then the FAL instruction moves the values to dint_array. This converts the values to 32-bit integers (DINTs), for use by other instructions in the ControlLogix controller. EXAMPLE Write integers to a PLC-5 controller.
Chapter 7 Interlocking and Data Transfer Between Controllers Receive MSGs from PLC-5 or SLC 500 Processors To receive MSGs from PLC-5 or SLC 500 processors, 1. If the originating controller is a PLC-5 or SLC 500 processor, in the MSG instruction, select PLC5.
Chapter 8 Send Email Introduction This chapter describes how to send an email through an EtherNet/IP module.
Chapter 8 Send Email The EtherNet/IP module sends only the content of a MSG instruction as an email to a mail relay server. Delivery of the email depends on the mail relay server. The EtherNet/IP module does not receive email.
Send Email Send Email Via a Controller-initiated Message Instruction Chapter 8 A Logix controller can send a generic CIP message instruction to the EtherNet/IP module that instructs the module to send an email message to a SMTP mail relay server using the standard SMTP protocol. This automatically communicates controller data and application conditions to appropriate personnel.
Chapter 8 Send Email The String Browser dialog box appears. 2. Enter the IP address or host name of the mail server. 3. Click OK. The tags for the email text and transmission status can contain up to 474 characters. For these tags, you must create a user-defined STRING data type. The default STRING data type in RSLogix 5000 programming software is not large enough for most email text. To create a user-defined STRING data type, perform this procedure. 1.
Send Email Chapter 8 The String dialog box appears. New Controller-scoped Tags 2. In the Name field, type a String type, such as EmailString. 3. Create one controller-scoped tag, such as EWEB_EMAIL, of this new data type to contain the email text. 4.

Click ... in the Value column of the Controller Tags dialog box.
Chapter 8 Send Email 6. Type your email. The text of the email does not have to be static. You can program a controller project to collect specific data to be sent in an email. 7. Click OK. For more information on using ladder logic to manipulate string data, see the Logix5000 Controllers Common Procedures Programming Manual, publication 1756-PM001.
Send Email Chapter 8 Enter the Ladder Logic Ladder logic requires two MSG instructions. One MSG instruction configures the mail server and needs to be executed only once. The second MSG instruction triggers the email. Execute this email MSG instruction as often as needed. The first rung configures the mail server. The second rung sends the email text.
Chapter 8 Send Email 2. In the Path field, type the path for the MSG instruction. The path starts with the controller initiating the MSG instruction. a. Enter the number of the port from which the message exits and the address of the next module in the path. For example, if the EtherNet/IP module is in the same chassis as the controller and is in slot 2, the path is: 1, 2.
Send Email Chapter 8 Configure the MSG Instruction That Contains the Email Text To configure the MSG instruction that contains the email text, perform this procedure. 1. Click the Configuration tab. The Source Length is the number of characters in the email tag plus 4 characters. In this example, the email text contains 65 characters. 2. Configure the MSG parameters for sending an email. a. From the Service Type pull-down menu, choose Custom. b. In the Service Code field, type 4b. c.
Chapter 8 Send Email 3. Click the Communication tab. 4. In the Path field, type the path from the controller to the EtherNet/IP module. The path starts with the controller initiating the MSG instruction. The second number in the path represents the port from which the message exits and the address of the next module in the path. For example, if the EtherNet/IP module is in the same chassis as the controller and is in slot 2, the path is: 1, 2. 5.
Send Email Enter Email Text Chapter 8 Use the string browser to enter the text of the email. To include To:, From:, and Subject: fields in the email, use symbols to separate each of these fields. The To: and From fields are required; the Subject: field is optional. For example: To: email address of recipient From: email address of sender Subject: subject of message body of email message An email message must not exceed 474 characters in length.
Chapter 8 Send Email Email Status Code Descriptions Error Code (Hex) Extended- Description error Code (Hex) 0xFF 0x0104 Unable to connect to SMTP mail server set in Attribute 5. If the mail server address is a host name, make sure that the device supports DNS, and that a Name Server is configured. If the hostname is not fully qualified, for example, “mailhost” and not “mailhost.xx.yy.com” then the domain must be configured as “xx.yy.com”.

Chapter 11 Troubleshoot an EtherNet/IP Module 2. Review the values in the Media Counters table. If Then Any media counters are greater than zero You need to investigate further. These errors are counted: · Alignment · FCS · Carrier Sense A duplex mismatch exists between your EtherNet/IP module and the switch port. To clear the duplex mismatch: a. Configure the EtherNet/IP module and the corresponding Ethernet switch port for a forced operation, not autonegotiation.
Troubleshoot an EtherNet/IP Module Switch Considerations Chapter 11 To help troubleshoot your EtherNet/IP network, you must use a managed switch. Some of the important features in a managed switch include: • Internet Group Multicast Protocol (IGMP) snooping. • support for Virtual Local Area Networks (VLAN). • port mirroring. IMPORTANT Use a switch equipped with wire-speed switching fabric.
Chapter 11 Troubleshoot an EtherNet/IP Module This example assumes that the switch does not support IGMP snooping querier function, so a router is required. IGMP Snooping Example Plant Network Router sends out IGMP polls to determine members of a multicast group. Switch listens to the polls and responses and identifies members of each multicast group.
Troubleshoot an EtherNet/IP Module Chapter 11 Port Mirroring Select a managed switch that supports port mirroring. With port mirroring, you can direct frames being transmitted on one port to another port for analysis by a traffic analyzer. Besides monitoring your Ethernet media counters, port mirroring enables you to immediately spot anomalies in traffic flow. A traffic analyzer can monitor the traffic on a given port and troubleshoot a problem.

Appendix C EtherNet/IP Network Connections Introduction EtherNet/IP communication modules use connections to manage communication. A connection is a point-to-point communication mechanism used to transfer data between a transmitter and a receiver. The EtherNet/IP communication modules use these connections: • CIP connections for Logix-based communication. A CIP connection transfers data from one Logix application running on one end node to a second Logix application running on another end node.
Appendix C EtherNet/IP Network Connections Types of CIP Connections CIP Connection Type Description Bridged A bridged connection is a connection that passes through the EtherNet/IP module. The end point of the connection is a module other than the EtherNet/IP module. Example: a connection from a controller through a 1756-ENBT module to another controller. Rack-optimized A rack-optimized connection is a connection to a rack or assembly object in the EtherNet/IP module.
EtherNet/IP Network Connections Multicast Address Limit Appendix C Connections that produce data over an Ethernet network use multicast addresses. EtherNet/IP modules support a maximum of 32 unique multicast addresses. The actual address, such as 239.192.22.121, is determined by the EtherNet/IP module. Example 1: An Ethernet adapter that produces data uses a unique multicast address for each I/O connection.

Appendix D EtherNet/IP Network Overview Introduction This appendix defines some basic Ethernet network concepts and how the EtherNet/IP protocol is used for control. Ethernet Protocols Topic Page Ethernet Protocols 217 Configuration Requirements 219 Manual Configuration on an Ethernet Switch 222 Change Ports on an Ethernet Switch 222 Additional Resources 222 On the most basic level, Ethernet is a wire or cable that connects computers and peripheral modules so that they can communicate.
Appendix D EtherNet/IP Network Overview Protocol Descriptions Protocol Description Simple network management protocol (SNMP) SNMP is a standard for network management within TCP/IP environments. This protocol enables client applications monitor and manage network information on host computers and gateways. This protocol is password-protected. SNMP uses a distributed architecture consisting of management systems and agents.
EtherNet/IP Network Overview Appendix D (COS) or at a requested packet interval (RPI). The frequency of update depends upon the options chosen during configuration and where on the network the input module resides. The input module, therefore, is a producer of input data and the controller is a consumer of the data. The controller can also produce data for other controllers to consume.
Appendix D EtherNet/IP Network Overview Each node on the same physical network must have an IP address of the same class and must have the same network ID. Each node on the same network must have a different local address (host ID), thus giving it a unique IP address. IP addresses are written as four-decimal integers (0...255) separated by periods where each integer gives the value of one byte of the IP address. For example, the 32-bit IP address: 10000010 00000000 00000000 00000001 is written as 130.0.0.
EtherNet/IP Network Overview Appendix D When host B communicates with host A, it knows from A’s IP address that A is on another network because the network IDs differ. To send data to A, B must have the IP address of the gateway connecting the two networks. In this example, the gateway’s IP address on Network 2 is 128.2.0.3. The gateway has two IP addresses (128.1.0.2 and 128.2.0.3). Network 1 hosts must use the first IP address, and Network 2 hosts must use the second IP address.
Appendix D EtherNet/IP Network Overview A second network with Hosts D and E has been added. Gateway G2 connects Network 2.1 with Network 2.2. Hosts D and E will use Gateway G2 to communicate with hosts not on Network 2.2. Hosts B and C will use Gateway G to communicate with hosts not on Network 2.1. When B is communicating with D, G (the configured Gateway for B) will route the data from B to D...G2. Manual Configuration on an Ethernet Switch The EtherNet/IP modules support these Ethernet settings.
