Config restore problem with EtherCat

Recommended Posts

I'm having a problem getting the EtherCat to work after doing a restore by putting a USB stick in the PowerPMAC via the PowerPMACConfigLoad directory. The backup file was taken off of a working PowerPMAC etherlite unit and we were trying to install it in second back up etherlite unit. The first unit works fine, we are just trying to create a backup unit for our customer. Everything on the second unit seems to work except that the EtherCat no longer communicates. Is there an extra step in doing a configuration restore for the EtherCat?

 

We were trying to catch a plane so I didn't have much time to trouble shoot this on site. Any help would be appreciated.

I suspect the file

 

/opt/etherlab/etc/sysconfig/ethercat

 

Is being overwritten by the backup. This file contains the MAC address of the ethernet card used for ethercat.

 

Issue the command

 

system ethercat master

 

The results will look as follows. If the line that contain Main: says has (waiting...)

the file was overwritten and that is the problem. If it has (attached) then it is o.k. and the problem is elsewhere.

 

 

 

system ethercat master

Master0

Phase: Idle

Active: no

Slaves: 6

Ethernet devices:

Main: 00:50:c2:12:c1:97 (attached)

Link: UP

Thanks for the info. I think the 2 units were purchased about 4 months apart, so they might have different versions of firmware. I'll check the file issue overwriting the MAC address. If that is the problem, would the fix be to remove that file from the config directory?

I've finally gotten back to trying to get this backup unit working. Some more info: The original PPMAC that we are taking the back up from is using firmware 1.4.0.27 and the new PPMAC we are setting up as a backup uses 1.5.8.0. When trying to use the IDE software to do a restore on the newer system it fails due to the difference in firmware versions. In light of the issues we had using the USB stick backup with the Ethercat, and now not being able to put the backup on due to the different firmware versions: What is the recommended way to setup this PPMAC with version 1.5.8.0 using the backup .tar file from the PPMAC running 1.4.0.27?
