[etherlab-users] Beckhoff EL2595 AL status message 0x001E: "Invalid input configuration"

[ronaldo.mercado at diamond.ac.uk]

Hello,

I am struggling with the control the constant current output slave EL2595.

The unit provides a few PDOs by default, to control the on/off
state. I wish to control the current output, (I believe at address 0x7000:11
"Output Current"). This should allow a slider to control the dimming of
an LED. This is not on the default PDO set.

I know it's supported because it was demonstrated with TwinCAT. TwinCAT
adds it to sync manager 2 with a check box.

My attempt with the attached c source program fails to set the slave
in the "OP" state, and the messages report "Invalid input
configuration".

Could you suggest what to do differently?
How do I add the PDO for the current control to the slave?

Thanks,

Ronaldo
