[etherlab-users] EL2502 problem

[Andreas Stewering-Bone]

Hello Michael,

Hardware version seems to be OK for the requested features.

you have to
- configure PDO 1602 and 1603
- configure PDO-Entries 7000:17 7000:18 7010:17 7010:18
- map PDO-Entries 7000:17 7000:18 7010:17 7010:18

and then it should work I think.

Do you get a failure message?
