How do I write to all 32 DO pins simultaneously on a 9477 on a 9144 EtherCAT chassis

[AnthonV]

Hi, the scan engine only allows me to write to 1 DO at a time when I address the 9477 32 DO c-series module.  I have several of these modules in a 9144 expansion chassis so I would hate to write 32xn times to set the values of these DO's.  Is there a way to address (using a U32) all 32 pins of a module in one write?

Any help would be appreciated.

Yes, you could use the programmatic way of writing Io variables, which would support to write multiple channels at ones.

If you use the discover  VI you do not need project deployment at all. The VI discovers your chassis and modules, Io variables and deploys them automatically.

Great thanks for the help. It looks a bit elaborate but if it works then I'm happy. I'll try this on Monday
