Controller release when using the Bus I/O(Std I/O + field functionmodul)
Question:
Does the use of the Bus I/O (I/O functionmodul and fieldbus functionmodul) require a controller enable at both modul's?
Answer:
No. The signal 'controller enable' (CINH = terminal X3/28) is not evualated in the fieldbus functionmodul and not transmitted to the I/O functionmodul.
Only the I/O functionmodul require a controller enable at terminal X3/28.
