The PLC is connected to the diagnostic repeater via DP, but communication is not established – the DP1 light does not turn on. How do I set up the diagnostic repeater?

Urgent, thanks!
Well, how should I put it? For which brand of diagnostic repeater is this? Do the address of the repeater station, the baud rate, the communication address, and so on match those required for communication with the PLC? Are there any issues with the power cables or signal cables? Let’s check each of these items one by one
