Hi guys Please can anyone help to me urgently. I have HP 6930p laptop and have also 2 cables for connection with TSX Premium Modicon but can not get connection with anyone of them to PLC. One cable is TSXPCX1031 ( serial ) and other one is usb TSXCUSB485.Have configured in driver manager and still same I am using Unity pro and PL7 software. When I turn selector switch on any cable then when turn to TER Direct or TER Multi then I could see green led blinks for second or two on CPU module ( this is for both cables) but after that I got message "Invalid Response" and that is in Modbus test mode while in Unitel mode nothing at all. So please if anyone knows what is going on I would be much obliged for help.
