Timestamping

Description
SIMOCODE pro V can timestamp up to eight digital signals with high temporal precision
(10 ms). In the process, every change in the state of the digital signals will be recorded.
Possible areas of application are:
● Precise chronological recording of faults in a procedural system
● Analysis of system-wide interrelationships
● Recording and signaling of time-critical signal changes
Requirements
To use SIMOCODE pro V time stamping, the DP master being used must support time
synchronization functions via PROFIBUS (e.g. DP master connections for SIMATIC S7-400),
or a master clock must be used (e.g. SICLOCK).
Process in STEP 7
Time-of-day synchronization for SIMOCODE pro V is activated in STEP 7 HW Config in the
slave properties under "Time Synchronization".
Note
The set synchronization interval must correspond to the configuration of the clock master.
For SIMOCODE pro, transmission of time stamped information is analogous to transmission
with SIMATIC S7 IM 153-2. Therefore, the "FB 62 TIMESTMP" function block can be used
for further processing of time stamped information in the CPU, to transmit time stamped
messages from the "Standard Library → Miscellaneous Blocks" library.
Note
The "LADDR" parameter contains the diagnostic address of the DP slave from
STEP 7 HW Config. In DP mode "DPV1" of the DP master – integrated via
OM SIMOCODE pro – LADDR2 contains the diagnostic address of slot 2 of SIMOCODE pro.
For all other configurations, LADDR2 will contain the same address as LADDR.
In contrast to the STEP7 online help for the FB62, when integrating via GSD, the slot
number of the module is transmitted with Slot 1 for signal messages, and with Slot 0 for
special messages.
You will find further information about the FB 62 in the STEP7 online help.
