Trouble connecting PM783F that used to work
Hi, im having problems connecting the PLC, it indicates it has a fault and wont let me detect it or change the IP address. We already checked all fisical connections and they are ok, any suggestions? It used to work well. First it said it had an error now its a fault.
Thanks a lot
On PM 783F error led is blinkinng red or is it steady ? what it is displaying on controller ?
are you able to ping controller ? if connected with controller on internet explorer type controller IP address and it will open up controller details. check at the end if there is any error history ?
By pressing ESC button on controller keypad, controller should come out of error/fault. and if error/fault persist it will go again to into same mode. but you can try that once.
If it used to work well, what went wrong ? any changes were downloaded or something before error or fault ? If it is running plant situation suggested to contact local abb helpline to get fast solution.
good luck !
