Acc 5EP3 Power ECAT Macro Lite Interface Manual Setup

Recommended Posts

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

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. Capture.JPG.8aa63b734e085493a3b351f92ed8be73.JPG

This post in the etherlabs forum seems to indicate this as well: http://lists.etherlab.org/pipermail/etherlab-users/2010/000868.html

 

Regards,

Felix

You are correct redundancy is not in the master yet.
