Hello experts,
I'm having problems connecting to a TSX P57104 Premium PLC.
I am using the cable TSXPCX1031 with an usb to serial converter.
I configured the COM port accordingly to device manager assingment. PC and controller seens to connect but not communicate.
In driver manager when I try to start the test an error appeared : error "ENOERROR" (0) in function send and receive!
Any thoughts about this issue?
Regards!

Unitelway Drivers with USB to Serial convertors used to be a real pain due to the timing requirements of the protocol - Better to use a USB to Unitelway cable TSXCUSB485+TSX CRJMD 25 or the TSXPCX3030 (which is USB version of the cable you have).
However, depending on the actual USB/Serial converter used, I have had success with the serial cable provided you use the latest Unitelway Driver (V2.9IE19) and make sure in the driver config, on the "Advanced" tab, you tick the "force virtual com port" option, this makes the driver more tolerance to the delays inherent in the usb to serial conversion.
