Block for timestamping MMLog
4.6.1
Description MMLog
The block executes the following functions:
●
Time stamping: SIMOCODE pro V PROFIBUS can timestamp up to 8 digital signals with
high temporal precision (10 ms). In the process, every change in the state of the digital
signals will be recorded. If the time stamping function is activated, SIMOCODE pro V
PROFIBUS transfers the time-stamped events to the control system additionally for the
signals configured in the device.
●
Logbook function: The block reads out the error buffer of SIMOCODE pro C / S / V and
SIMOCODE pro V PROFINET.
This logbook function is available for all basic units.
Time stamping function with SIMOCODE pro V PROFIBUS
To use time stamping, the DP master being used must support the time synchronization
function via PROFIBUS (e.g. DP master connections for SIMATIC S7-400). Alternatively,
you can use a master clock (e.g. SICLOCK).
You can activate time synchronization for SIMOCODE pro V in STEP 7 HW Config in the
slave properties under "Time Synchronization".
The set synchronization interval must correspond to the configuration of the clock master.
The time-stamped events are saved in the device and transferred to the control system. This
is displayed in the Alarm view.
Logbook function with SIMOCODE pro V PROFINET
SIMOCODE pro V PROFINET supports time synchronization via the Network Time Protocol
(NTP).
If a valid time is available, the trip errors and events in the error buffer are logged with the
date and time of day (real-time stamping).
For the SIMOCODE pro PROFIBUS, logging of events is carried out with a time stamp that
reproduces the operating hours of the device.
