[etherlab-users] EtherCAT newbie - NXIO 100-RE

[Christian Gieseler]

Hello Clemens
There are two things i found that may cause your problems:

First in your domain1_regs the inputs of the slave to the master are commented out, so off_dig_in has not the correct value and you don´t write to the correct spot.

Then second you did not specify the bit-offset in your domain1_regs. Since your pdos are not full bytes this can cause trouble when writing, reading the domain_pd.

Regards Christian
