Hello.
The status of my X20CP1584 CPU is as follows:
-R/E LED: off
-RDY/F LED: off
-S/E Led: off
-PLK Led: off
-ETH LED: off
-CF LED: flashing green
-DC LED: flashing orange
POWER SUPPLY STATUS:
r: green turns red and turns off and so on
INPUT/OUTPUT MODULES STATUS:
r: flashing green
Does anyone have any idea what’s going on with my PLC?
not sure,I do not have manual in front of me, but could it not be that PLC is trying to read content from CF card? So either wait or try different CF card if PLC is in this state for long time.
Hello again.
The time we have waited for the PLC to change state has not exceeded 5 minutes, but it is not an extensive project either, it always usually reads the card in less than 2 minutes.
We will perform a restore of the project on a new CF card and test.
If anyone can offer us some information about the status of the plc’s LEDs, it would be of great help.
Greetings and thanks.
Here is some information about the PLC’s LEDs and here is some information about the power supply’s LEDs.
The power supply light turning off and on again is interesting because it kind of sounds like the PLC is rebooting. That might also explain why the other lights never light up.
Did you make any progress by restoring the project on a new CF card? Something in the project could be corrupt, so I’d also recommend double checking that you have the correct CPU in your project and testing a new, blank project to ensure the PLC is working correctly.
Hello.
This morning we tried with a new CF card and with a .zp3 restoration copy from the utility center.
At first the CPU connected well and all its LED’s were in proper operation.
But when we tried to access by REAL VNC server then it was when the CPU changed to the error state again, and we no longer get it to read the project from the new CF card.
This has also been done sometimes running the project and suddenly from one moment to the next the project stops running and the error of the Led’s appears and stops working.
According to what they tell me, it may be that one of the I/S modules heats up and fails, it has Digital, analog and DS 1319 I/S modules
We are a little frustrated, any help always grateful.
If you’re worried about an I/O module causing the issue, you could remove the I/O and try running just the PLC to see if that makes a difference.
When the PLC rebooted after launching the VNC server, do the lights follow the same pattern? It may just be going into Service mode in this case.
Also, have you tried connecting in Automation Studio? Are you able to see a status of the PLC in the Online->Settings window?

1 PLC x20cp1584 (ip 192.168.250.10 local network)
2 ABB variators (connection with powerlink PLC)
Case 2;
1 PLC x20cp1584 (same ip 192.168.250.10 as in case 1)
2 ABB variators (connection with powerlink PLC
PC with REAL VNC software in range with the two PLC’s
We made the error of in case 1 the project was running we disconnected the ethernet cable on the PC and connected the ethernet cable of case 2 to the PC.
We don’t know if this will have created any conflict, I understand that not, but the variators were connected by powerlink.
Just for my curiosity, is something in the logger recorded?
We have just sent the CPU to the technical service, as soon as they tell us the diagnosis we will notify it here to inform and learn, while we cannot perform any action.
Thank you in advance.
Hello again.
We are trying to solve this big problem, and from the technical service (it is the supplier but not the programmers of the project) they tell us that the CPU1584 is continually restarting and cannot start.
They send us a video showing the CPU failure, we also want to share the video with you, here I send it to you.
Meanwhile, they have made us an offer of a new CPU, but we would greatly appreciate any suggestions on how to recover the one that is failing.
Any help would be very grateful, as you can see in the video the CPU is outside the I/O modules (they are not the problem) and it cannot start and restarts continuously.
We have also tried trying another CF card and it does not change the situation at all.
Any help always grateful.
Switch to diagnostic mode, connect and try to read logger. If the problem is only reproducible with CF card with project plugged in, logger can tell you more. You can also read logger directly from CF card.
-Is there any possibility of knowing any type of diagnosis from the cf card with card reader without cpu 1584?
You can follow the instructions on this post for pulling the log files off of the card and then check them for any available error information.
But in order to say for sure whether or not it’s the CPU or the program that’s faulty, you’d have to test your CPU with a known working (i.e. blank) project.
When we have the 1584 CPU again with a failure in our installations then we will try pinging in SDM and we will also try with a new blank project.
Meanwhile, we can only work with the cf card from a reader and download the files as you explain well, but these files:
-Can they only be interpreted by B&R service?
-Can we read/interpret the diagnostic files (tools)?
Yes, you can interpret them. The guide I linked shows how to copy the log files from the card. These can be opened in the Automation Studio Logger. Instead of connecting to a target, click the Open button and then browse for the files you pulled from the CF card:
I suspect any errors preventing the PLC from booting will be shown in the System logger, but it would be good to check them all for recent errors just in case.
Thank you Marcus.
We will try and I will keep you informed., thank you for your generous help
You’re welcome! Feel free to upload screenshots or the log files here if you need help deciphering them.
