Appendix B MSG_CIPGENERIC Function Block
AppCfg Input CIPAPPCFG CIP Service and application path configuration. This is a structured data type, that consists of the
following elements:
• AppCfg.Service (USINT)
- Service code
• AppCfg.Class (UINT)
- Logical segment’s Class ID value
• AppCfg.Instance (UDINT)
- Logical segment’s Instance ID value
• AppCfg.Attribute (UINT)
- Logical segment’s attribute value
• AppCfg.MemberCnt (UINT)
- Maximum Member ID values used (Normally this parameter not used, which means set to 0);
0 =No Member ID used
• AppCfg.MemberId (UINT)
- Member ID values (Normally this parameter is not used.)
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>”}
Example 1: From Micro850 embedded Ethernet port (which is port number 4) send message to a
device within same subset network with IP address 192.168.1.100 then the path is
TargetCfg.Path := ‘4, 192.168.1.100’
Example 2: 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
is 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 CIP connection upon message completion [Default].
ReqData Input USINT Array CIP message request data (data to be written to the destination). The array size should not be less
than the ‘ReqLength’ size.
ReqLength Input UINT CIP message request data length (unit: byte), Number of bytes to write to the destination.
Range: 0...490
