RS485 communication with a PLC
« on: October 18, 2012, 09:50:06 PM »

Hello everyone.

I have a machine that is equipped with led lights. The entire machine is controlled by a PLC (Siemens S7-1200). Now I wonder if there is a way to contol the Velleman DMX controller with the PLC, so the lights can be controlled by the plc as well. The plc has a standard RJ45 output which runs profinet, tc-ip as wel as modbus protocol. I can also connect a RS485 bus adapter to the PLC.
Does annyone have any idea? And if so does anyone know what the data structure of the velleman contoller or the DMX protocol looks like? Should I adress a register or datablock? Any help in this matter would be highly appreciated.

Hi

How can I connect Siemens plc S7 400 with CP443-1 and Premium PLC TSX P573634M?
Both support Modbus TCP

Please if you have a sample program or a Manual that I can use to communicate this,
provide to me.
