Allen-Bradley MicroLogix 1400 User Manual

Publication 1766-RM001A-EN-P - October 2008
438 Communications Instructions
Example 6 - Configuring Local Write message with ST file
The MicroLogix 1400 can use a message instruction to transfer string file
data to target device (SLC5/0x, 1756-L1)
The following message setup screen is used to send local PLC5 write to
the 1756-L1 via 1756-ENBT module. A message read will also work.
The “rcv_string” tag on the ControlLogix controller is created as a string
type and mapped PLC/SLC mapping table to allow the controller to accept
those messages.
