Communicate Over a Remote I/O Network 20-19
Send the Message to a BT Module
1. Enter the following rung:
The MSG instruction reads the input values from a BT module and stores the values in BTR_int_buffer_read .
•
Each time the instruction is done, it automatically restarts and sends another message.
•
Prior to each message, the series of MOV and COPY instructions load the appropriate configuration properties into
the MSG instruction so it can read the next BT module. The configuration properties load from the
BTR_cfg array.
•
After each MSG, a subsequent rung increments the BTR_index tag. This loads the configuration properties for the
next module into the MSG instruction before it executes again.
