Requirements: You can only use the FB TIMESTMP in configurations that support time forwarding and time stamping of binary signals. These are as follows: CPUs: CPU 4xx with CP443-5 for forwarding time messages (from 6GK7443-5DX02-0XE0) or CPU 4xx with forwarding of the time messages (e.g. CPU416-2 DP from firmware version 3.0) regards
