Check the communication parameters before downloading a program. Control FPWIN Pro7 can communicate with your PLC directly via:
COM (USB)
Ethernet
USB (via GT panel)

You can also connect to a PLC network. The settings to be made depend on the PLC type and on the kind of connection. Control FPWIN Pro7 automatically searches for the suitable parameters, unless you have deactivated this feature. Please also refer to the corresponding hardware manuals.
