bradp Posted August 4, 2011 Share Posted August 4, 2011 The ACC5EP3 is being tested by a few people who might need to know the manual setup procedure for the second ECAT port. The file to change is /opt/etherlab/etc/sysconfig/ethercat To be able to do it, we have to make the partition /opt writable then modifiy this ethercat file and then make the partition /opt write protected again. 1. Connect to PPMAC using a Telnet, SSH, or Serial connection. 2. Make the partition writeable. Be carefule here because if you do not know what you are doing you can corrupt the PPmac files. Enter the command> mount -o remount,rw /opt 3. modify the file /opt/etherlab/etc/sysconfig/ethercat At this point there are two ways to set it up. One way is as Two masters MASTER0_DEVICE="00:50:C2:12:C1:XX" MASTER1_DEVICE="00:50:C2:12:C1:XY" The other way is as a single master with redundancy MASTER0_DEVICE="00:50:C2:12:C1:XX" BACKUP0_DEVICE="00:50:C2:12:C1:XY" Either way the second adapter is always 1 less than the first. For example. MASTER0_DEVICE="00:50:C2:12:C1:7D" MASTER1_DEVICE="00:50:C2:12:C1:7C" 4. Make the partition Read Only. Enter Command> mount -o remount,ro /opt 4. reboot PPMAC Link to comment Share on other sites More sharing options...
Felix Posted August 26, 2011 Share Posted August 26, 2011 Brad, I believe the proper syntax for configuration of a single master with redundancy is MASTER0_DEVICE="00:50:C2:12:C1:XX" MASTER0_BACKUP="00:50:C2:12:C1:XY" However, it appears that IgH has not yet implemented this functionality as querying the state of the ethercat module always results in a status of waiting for the Backup Port. This post in the etherlabs forum seems to indicate this as well: http://lists.etherlab.org/pipermail/etherlab-users/2010/000868.html Regards, Felix Link to comment Share on other sites More sharing options...
hbausley Posted August 29, 2011 Share Posted August 29, 2011 You are correct redundancy is not in the master yet.
