Hi Crossbow, Opposite way around, so the NX1P2 is the slave and the BMS is polling it for information. Basically its a new hospital build and the PLC is controlling some fuel pumps, the BMS monitors the whole building and thus wants information from the PLC. As for IP address it only has the factory one that I haven't changed yet.

Hi Gents, I've got a project I'm working on at the moment and we need an NX1P2 to connect via modbus TCP/IP to a building management system to monitor some digital inputs and outputs and some internal BOOL variables, there doesn't seem to be a lot of information available for this. So far I've found the function block online, added it to the program but I've been unable to even ping the PLC thus far. Does any one have any sample programs for this that I can use for reference? do I need to map these variables to a table somewhere? Can anyone explain how this is meant to work. Bare with me this is my first project using this platform.
