expansion error

[active]

Hi all

I have a V570 its been on site for 1 year, twice in the last 2 months Ive had an expansion error when someone goes there all the card run lights are solid is there any SB or SI that will tell me which card is causing the issue also would be nice if you could automatically reset fault so plc starts up again.

Thanks

Useful information.

Help needed.

Configuration:

Vision 120

Ext. adapter EX-A1

IO-DI16

IO-A14-AO2

Error:

Expansion error

1- 0x0000;  2 - 0; 3-0x0000; 4 - 0x0000; 5-0x00000000

It works for copule of hours, then this error displays.

Can somebody tell me what to do?

The first thing I would do is check or replace the cable between the PLC and expansion adapter. Then check the connections between the EX and IO modules.

I'll try that today.

Thank You!

Also check that the earth on this cable is correctly done, and check with a meter that it actually does bring the terminal to earth.

cheers,

I have checked all of the above. Haven't noticed anything unusual.

How did you check all the connections? Visual inspection is often not enough. Try wiggling each of the components to see if you can induce a fail.

[Vladimir]

Yes, i have shook all of the connections, cables and units. Nothing had happened.

[Flex727]

Check your power supply to the EX-A1 module.

I have displaced cable between PLC and expansion adapter apart from other cables. Everything works fine for now.
Thanks a lot to everybody!
