Hi

I have a 1214C DC/DC/DC and a Danfoss VLT FCD 300.

I want to do a cyclic communication PPO type 3 with the VLT

And a acyclic communication with the VLT for parameter download.

I have the VLT in the network overview and I'm looking for some program examples for the PLC program??

Hope you can help?


Thanks in advance
