Hi all I was having a look at what I wanted to do with Modbus/TCP slave and realised that It is possible to aproach this area from a completely different angle than Modbus/TCP master. I am thinking of allowing the whole LPLC io map to be referenced to the holding register Modbus map. ie 40001 to 49999. This would mean that all bits would be referenced as read only and any io_point that was assigned to modbus_tcp_slave would be driven from some external device over ethernet. It also means that only one Modbus function is required to drive all io. (Keep It Simple). All other requests would reply with an exception error. Does this sound feasable or do we want to make it complicated and assign individual points to each modbus address as required. -- Regards Philip Costigan _______________________________________________ LinuxPLC mailing list [email protected] http://linuxplc.org/mailman/listinfo/linuxplc
