Hello, good afternoon, I have a problem with a TCT500, when entering with the PL.Prog4.75 software and trying to communicate with the PLC the message that appears is "Device does not answer", I have verified that the cable is in good condition. status because I have tried it with another device and it works. I have also tried updating firmware as indicated in viewtopic.php?t=2483, but I cannot connect to the PLC, some other solution?
I also see in the software an "Upgrade Boot Version" option, can that function be useful?

Hi,
are you using a native RS232 or an USB-RS232 converter? If you use a converter, please check in the converter driver settings to configure the transmit delay as as lower as possible.

You can try using the "Upgrade Boot Version" option, basketball stars as it may help reinitialize communication with the TCT500, especially if the firmware update method didn’t work.
