Hello,
In this case your PLC will be a Modbus "Server", and the SCADA system (I expect) will be able to act as a Modbus Client.
In your PC Worx 6 project, you need to put your process data into an array of WORD variables, and then set up the Server function block to make this array of WORDs available to clients in Modbus register numbers 40001 onwards.
If you need more support on PC Worx 6 software or the ILC controller, then it is generally best to contact your local Phoenix Contact office, where they will be able to offer technical support on these products.
If you have any questions on PLCnext Technology - including PLCnext Engineer software or PLCnext Control PLCs, then this is the right place for questions on those products. :-)
