hi
If the manufactor of the plc says that his PLC supports modbus protocol , does that mean that I can use any ( modbus ptotocol OPC server ) with this PLC to make SCADA/HMI system ?
for example :
master-k series PLC from LG ( it supports modbus protocol )
opc server : the modbus opc server that matrikon offers .
Can these two things work together in order to design a scada software ( I desighn it by VB6 with some Activex controls)
thanks for your replies .
