Fundamentals of Time Stamping
Properties
Time stamping is possible with the IM 152
● in customer applications using FB 62 (FB TIMESTMP)
(see also the STEP 7 Online Help).
● with the PCS 7 system solution accurate to 20 ms
For a detailed description of the time sampling and the time-of-day synchronization, consult
the
PCS 7 function manual "10 ms time stamping".
Principle of operation
A modified input signal is assigned a time stamp and stored in a buffer (data record). If time
stamped signals exists or a data record is full, a hardware interrupt is generated to the DP
master. The buffer is evaluated with "Read data record". Special messages are generated for
events that influence the time stamping (communication with the DP master interrupted, frame
failure of time master, ...).
