Yokogawa Standalone MW100 - Manual (Page 37)

In the example below, on Rung 0000, the 1746-NT4 Thermocouple Input module is being configured on the SLC 5/04’s
first scan. The next rung (Rung 0001) contains a MSG instruction, which writes Input words I:1.0 thru I:1.3 (1746-NT4
Input Channels 0-3) to the MW100’s Communication Channels C01-C04. In Rung 003, a MSG instruction reads data from
the MW100, Measurement Channels 1-10, and stores the data in F8:0-F8:9.
The MSG Write instruction on Rung 0001 is configured as follows:
Type – Peer-To-Peer (default value, cannot be changed)
Read/Write – Write
Target Device – 500CPU
Local/Remote – Local
Control Block – N7:0
The MSG Write instruction is configured to use Control Block N7:0. The Control Block Length will be set automatically
based on the information contained in the MSG instruction. DO NOT ALLOW CONTROL BLOCK ADRESSES TO
OVERLAP AS UNPREDICABLE RESULT MAY OCCUR. The Control Block Word Enable Bit (N7:0/15) is used to
continuously toggle the instruction. If another data transmission interval is required, configure the rung appropriately.
Double clicking on the ―Setup Screen‖ portion of the instruction accesses the MSG Instruction configuration.
