Custom App/Plugin
Overview
You can create custom applications for the IOLAN by using the Perle SDK. See the SDK
Programmer’s Guide (the SDK and guide are found on the Perle website at
www.perle.com/downloads/index.shtml) for information about the functions that are
supported. You must download the program and any ancillary files to the IOLAN and set the Serial
Port Profile
to Custom App/Plugin to run a custom application. You must also specify the program
executable in the
Command Line parameter.
A custom application or plugin can be run on the serial port. In this situation, the application will start
once the serial port is activated and operate solely on the context of that serial port and any network
communications related to that serial port. You could run a different custom application on each serial
port. The serial port custom application or plugin is configured by specifying the
Custom
App/Plugin
profile for the serial port.
The system level custom application or plugin will begin execution immediately following the system
startup. It runs on the context of the whole system and can access network communications as well as
any or all serial ports.
Internet Address The IP address of the SNMP manager that will send requests to the IOLAN. If
the address is
0.0.0.0, any SNMP manager with the Community Name can
access the IOLAN.
Permissions Permits the IOLAN to respond to SNMP requests.
Data Options:
z None—There is no response to requests from SNMP.
z Readonly—Responds only to Read requests from SNMP.
z Readwrite—Responds to both Read and Write requests from SNMP.
Default: None
Read-Write User Specified user can view and edit SNMP variables.
Read-Only User Specified user can only view SNMP variables.
Trap The trap receiver is the network management system (NMS) that should
receive the SNMP traps. This NMS must have the same SNMP community
string as the trap sender.
Internet Address Defines the hosts (by IP address) that will receive trap messages generated by
the IOLAN. Up to four trap hosts can be defined.
