Hi,
Whether the connection is possible through:
laptop (Windovs7x32) -> usb-rs232 (HL-340)(Virtual COM) -> VIPA green cable -> VIPA CPU 114?
Everything seems is connected properly(tested and works alone fine), but Winplc7 v5 still writes:
Error when starting communication: Can not connect to MPI adapter. MPI-adapter connected to the correct interface?
Does anyone know anything about such schemes and their features?
Do I need a driver in addition to the VIPA green cable, where can I get it exactly and how to use it in these conditions?
Vipa Serial Interface Setup:
Vipa CPU 114-6BJ02 and virtual com port

Re: Vipa CPU 114-6BJ02 and virtual com port
The question is still under investigation, seems after repairing controller has another electric charactaristics,
because it does not work:
laptop (Windovs7x32) -> usb-rs232 (HL-340)(Virtual COM) -> VIPA green cable -> VIPA CPU 114
Tested with several different operating systems, Virtual COM cables and ports.
but it does work:
laptop with real COM(Serial port)(Windovs7x32) -> VIPA green cable -> VIPA CPU 114
It seems insufficient voltage from the USB.
If anyone has any other idea, please you are welcome.

You need to check:
1. number of the com-port (in device manager)
2. "baud rate MPI cable"deice (speed of the com-port)
3. "baud rate MPI ring" (speed of the MPI)

After further investigation it was found out that the controller is connected and programmed according to the scheme:
laptop (Windovs7x32) -> usb-rs232 (HL-340)(Virtual COM) -> VIPA green cable -> VIPA CPU 114
(by default without any additional changes in the connection speeds or serial port number)
but after the installation on the line, it's connected only through the scheme:
laptop with real COM(Serial port)(Windovs7x32) -> VIPA green cable -> VIPA CPU 114
He also refuses to connect to the scheme:
laptop (Windovs7x32) -> usb-rs232 (HL-340)(Virtual COM) -> VIPA green cable -> VIPA CPU 114
even after the dismantling from the line.
