I am workign on a project which has an X3, SAFEX C12, ctrlX IO bus coupler+IO, then a Kistler Data Logger last on the EtherCat.
I can communicate to the C12 and IO with no problems. However, when I add the Kistler unit (using IO works, datalayer update and download) the EtherCat stops working at the ctrlX IO node. If I just have the Kistler unit by itself it works fine.
What could cause this? What information do I need to provide for someone to help me debug?
