Yokogawa Standalone MW100 - Manual (Page 23)

In the example below, on Rung 0000, the 1746-NT4 Thermocouple Input module is being configured on the SLC 5/05’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 DX Advanced Communication Channels C01-C04.
In Rung 003, a MSG instruction reads data from the DX Advanced, 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 – N10:0
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’s Enable Bit (N10:0/15) 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.
