To communicate from one station connected to the Fipio bus to an outside device, the transmitter station must send to the master PLC and not the destination device (requests are not sent directly).
NOTE: The master PLC project transfers requests to the destination device.
The following example shows an exchange from the Fipio bus to the Uni-Telway bus. Exchanges in the other direction use an identical procedure.
The transmitter station, connected to Fipio connection point 6, sends the request to the master PLC. The destination address is the address of the master PLC.
WRITE_VAR (ADDR('\2.0\SYS'), '%MW',0,10, %MW10:10, %MW100:4)
The report is provided by the master PLC.
When the master PLC project receives the request from the transmitter station, it sends it to the destination device according to the Uni-Telway protocol.
WRITE_VAR (ADDR('0.0.0.1'), '%MW',100,10, %MW10:10, %MW40:4)
The report is addressed to the master PLC.
