Brief introduction to commissioning the time stamping
If you use the DPV1 blocks "RALMR" and "RDREC", then commission an ET 200M with time
stamping of the input signals as follows:
Step
Activity
Description
1.
Provide the DP master with the
GSD file.
The information as to which DPV1 slave
(IM 153-2BAx1) it must expect on the
PROFIBUS DP, is obtained by your DP master from
the GSD file.
The GSD file for the IM 153-2BAx1 can be found in
the Internet

2.
Integrate the slave with the DP
master.
Add the IM 153-2 to the DP line of your master
system and enter the used modules as of slot 4 of
the ET 200M.
3.
Set the mode of synchronization
and synchronization interval for the
master and slave.
Master:
•
Type of synchronization: Master
•
Synchronization interval: e.g. 10 s
Slave:
•
Time synchronization: active
•
Synchronization interval: e.g. 10 s
The synchronization intervals for master and slave
must be the same.
4.
Commission the ET 200M on the
PROFIBUS DP.
•
Transfer the settings to the master.
•
Connect the master and slave.
•
Check the set slave address.
•
Switch the unit on.
After start-up the slave communicates with the
master without interruption i.e. the LED "ON" lights
up and the LED "BF1" is off.
If this is not the case, you should either read and
evaluate the diagnostics data from the slave or use
a PROFIBUS monitor to analyze the
communication.
5.
Enable the time stamping.
The time stamping is activated by writing the data
record 240 on the IM 153-2.
The data record 240 essentially stipulates
•
at which slots which channels are supposed to
be time stamped
•
which signal change (0 → 1 or 1 → 0) leads to an
incoming or outgoing message
