ccdubs Posted January 5, 2009 Share Posted January 5, 2009 Hi All, I have an application where I want to read data from a Tri PLC. This will be a combination of I/O, relay coils and memory variables. What is the most efficient way to do this? Should I use channels and the built in TriLogi device? Or use a MODBUS script and I/O map all the PLC data I want into a memory address range on the PLC? I'm thinking the latter as this would gaurentee the need for only 1 communication and minimise comms overhead. Thanks. Link to comment Share on other sites More sharing options...
