Select the CPU in the Physical View.

Go to Configuration (tab) \ Timing \System timer (drop-down). Choose

EPL/X2X Interface. Then in the

Interface (drop-down) line below,select the PL inter!ace address.

Go to Configuration (tab) \ Timing \

Idle time \ Task class idle time[µs]. Chan"e it to a whole n#$ber$#ltiple o! the syste$ tic%.

Go to Configuration (tab) \esources \ Cyclic task classes.

Update each cyclic&s d#ration and
