8.2.4.5 Configuring the time stamping
For configuring the time stamping of input signals the IM 153-2 makes available an interface
in the form of the data record 240. There you can choose your requirements accordingly,
• whether the time stamping should be generally activated / deactivated
• on which slot a module is inserted, the input signals of which should be stamped
• which signals receive a time stamp (via "DI n Enable": time stamping activated /
deactivated)
• which signal change will be stamped in which way (via "DI n Edge": "rising" edge as an
incoming signal or "falling" edge as an incoming signal).
The unselected edge is automatically the outgoing signal, i.e. both changes of a signal are
given a time stamp.
With DS_WRITE the data record 240 is transferred to the IM 153-2 for the configuration of the
time stamp.
