Hi,
I need to communicate between an S7200 and visual basic running on a PC. I have come up with two options.
OPC - I know I can get an opc client and server. There is an active x control which acts as an OPC clien which can sit in my VB. This option is expensive.
Modbus - This is cheaper but i dont know if there is an activex object/ simple source code which can handle this.
Anybody done this? or know of any solutions?
The OPC server/client I was looking at was Kepware but I need to know about the modbus.
Thanks
