Pm 783f Ethernet Problem
I am writing from Turkey. I have a important problem. I am using ac700f with freelance. There is no problem 2 days ago but now there is a problem that it is ethernet. I connected a cable for modbus to modbus terminal. Than cpu show a eth fault and error blinking. It is blinking. I don't ping from server to cpu. How i can reset cpu or can you give a suggest for me?
I need your help, have a nice day
sorry but can not conclude what is problem and what is cause of consequence !!
But if your controller is not in running plant or not executing any process in real time.
Take backup of project, just remove battery(if you have battery in controller) and power off controller for atleast 5 min. then power again, plug battery and make whole station download. this should resolve the problem. Note that you need CBF and project backup for this.
this is not a good solution,
You should know the cause of problem and then solve it, if this issue is repeats again pls come back with some images and proper description.
It's good that Error LED is blinking not steady. with respect to your question in last comment
you can connect controller via diag cable at diag port and change/set ip address via hyper terminal. another way if you do not have diag cable then as I replied before follow this steps
1.Remove ethernet cable and any modbus\serial cable commented to controller. and press ESC key for a while(1-2 min) check if controller reboots and comeback without error? If no
2.Remove backup battery if any
3.Power off controller wait for 5 min at least and power again ? after power on check LCD display it should display 'noconF' text. means controller is not having any configuration.
4.in your case as you don't know IP address. power off controller again and press CFG button and power on again. follow attached doc to set IP address.
5.now connect Ethernet cable to controller and ping set ip from the PC in same network/subnet. if pingining
6.check in CBF in project in network config that IP address is same as assigned to controller. go to commissioning mode and download to controller via whole station download.
By this you get loaded with your project to controller and connected to network.
keep watching ERR LED if it lights up red again, to verify it's hw or programming error? Check in commissioning mode in ptree under resource if you find any task is stopped ? or double click on controller resource node, some popup window opens up check if there is any info in Error or in Error object box.
If no error there is something related to HW. if so from CBF PC on internet explorer type IP address of controller. this will open up controller web server.
Check log or module details if there is any entry for hw error.
Still if not get resolved, get assistance from local\regional ABB support line.
