Software compatibility: communication with the exterior
Introduction To communicate from a station connected to the FIPIO bus to an outside device, the transmitter station must address the master PLC and not the destination device
(requests are not routed directly).
Example
Note: The master PLC application transfers these requests to the destination device.
In the following example, an exchange from the FIPIO bus to the Uni-telway bus has to be performed. For a transfer in the opposite direction, the procedure is identical.

Step 1
Step 2
The transmitter station, connected to connection port 6 on FIPIO, sends the request to the master PLC. The destination address is the master PLC address.
WRITE_VAR (ADR#\6.1.0\SYS, %MW,0,10, %MW:10, %MW100:4)
The master PLC generates the report.
When the master PLC application receives the request from the transmitter station, it directs it to the destination device in accordance with the Uni-telway protocol.
WRITE_VAR (ADR#0.0.1, '%MW', 100, 10, %MW10:10, %MW40:4)
The report is sent to the master PLC.
