Allen Bradley SLC 5/03 won't power on even there is Power supply.

Are you sure? did someone tell you this or did you see it? the battery light will not flash, when the battery is bad it will be solid, the light above the battery will flash and that means you have a recoverable fault

Watch out when plugging just anything into the RJ45 port on the PLC, it has 24 VDC and unless you are using a UIC or other device then you will blow up your other end (PC)

You can use a 1747-UIC for the DH485 (RJ45) port or a 1747-CP3 (null modem/cross over) cable on the RS232 BD9 port

Hi geniusintraining,

The battery is still ok. yes you are correct the fault indicator is flashing. I'm sorry for what I state from the first topic

Thank you for your advice.

Actually I am just assisting the PLC programmer to troubleshoot this thing.

I want to ask something.

No to connect to the DH485 port you need the UIC convertor, there is no get around without a AB adapter of some type.
It is a DH 485 port not a serial port. NOTE the DH 485 not a RS 485 port. This is a special port for AB SLC that is why you need the adapter.
Without this adapter you need to connect to the RS232 port thru AB linx setup using a hard COM port on the laptop or a USB to serial adapter

Thanks a lot cowboy!

It is better to buy this DH485 converter
than to costumized a cable and then, it will fail again.
