MSG_CIPSYMBOLIC Function Block Appendix A
TargetCfg Input CIPTARGETCFG Target device configuration. This is a structured data type. It consists of the following elements:
• TargetCfg.Path (String)
Target information. Maximum two hops can be specified. {“<port>,<node/slot address>”}
Example1: From Micro850 embedded Ethernet port (which is port number 4), send message to a
device with in same subset network with IP address 192.168.1.100 then the path is
TargetCfg.Path := ‘4, 192.168.1.100’
Example2: From Micro830 Embedded serial port (which is port number 2), to reach a device at
Node 1. TargetCfg.Path := ‘2, 1’
• TargetCfg.CipConnMode (USINT)
CIP Connection type. ‘0’ – Unconnected (Default), ‘1’ – Class 3 connection
• TargetCfg.UcmmTimeout (UDINT)
Unconnected message timeout (in milliseconds)
Amount of time to wait for a reply for an unconnected messages (including connection
establishment for connected message)
Range: 250...10,000, set to 0 to use the default value 3000. Specifying any value less than 250 is
set as 250 and any value greater than maximum value is set as 10,000.
• TargetCfg.ConnMsgTimeout (UINT)
Class3 Connection timeout (in milliseconds)
Amount of time to wait for a reply for connected messages. The CIP connection is closed if this
timeout expires.
Range: 800...10,000, set to 0 to use the default value 10000. Specifying any value less than 800
will be set as 800 and any value greater than maximum value is set as 10,000.
• TargetCfg.ConnClose (UINT)
Connection closing behavior.
True: Close the CIP connection upon message completion.
False: Do not close the connection upon message completion [Default].
Data Input USINT Array This is an Input/Output parameter.
Read command stores the data returned from server. Write command buffers the data to be sent to
the server. When a MSG is triggered (or re-triggered), data is cleared for MSG Read command.
Range: 1…490
Q Output BOOLEAN TRUE: MSG instruction has finished successfully.
FALSE: Not finished.
After ‘Q’ is true, even when ‘IN’ turns to false, the Q stays true until ‘IN’ is triggered again.
