Note
With IM 153-2 (6ES7 153-2Bx00-0XB0), the use of active bus modules is not
intended for clock-synchronized operation since the synchronization conditions for
this application are fulfilled by certain modules only.
If active bus modules are to be used despite this, the user must include an extra
time of 500 µs for both Ti and To, therefore adding 1 millisecond to the equidistant
DP cycle.
Further Information
Further information on clock synchronism can be found in the online help of
STEP 7.
