i want to make a program on pc by using VB. in this program i will sent some data to plc CQM1H-cpu 51). in plc program will use that data to control some equipment.
but i don't how to connect plc to computer. i hope anyone whom can explain me how can i do that. sorry because my english is not very good
I used OPC instead. It was easier for me to connect to OMRON PLC that way.
Here is the link to the OPC Server for OMRON:
You will need to install it and then from the drop down menu, select OMRON PLC and you will have access to your data directly.
Hope this was helpful
