Hi,
Briefly, We have made HMI connected to PLC via opc server. Now that we have to use Modbus Tcp or RTU instead OPC Server. i need some information.
First of all, How the topology should be?
is Modbus slave used for server or Modbus Master?
And we will develop our own Modbus Connection libraries with c++.
