SOLVED
I/O Engineering v 1.8.0
I would like to use the Startup Parameters to set initial values to a EtherCAT-slave, in my example it's a IndraDrive Cs. I'm not able to deal with negative values. T.e. I would like to write the negative position limit (S-0-0050). But this is not working. Positive values are working well.
It looks like a topic of the type interpretation because it is working with other drives. I will talk to our R&D.
As a workaround please try to use the UINT value instead of INT e.g. -300 = FFFF FED4 = 4294966996.
