Dp Slave Properties" Dialog Box - Siemens SIMATIC ET 200M Manual

3. Settings at the DP slave:
"Object Properties" of the DP slave> "Clock Synchronization" tab
– Activate "Synchronize DP slave with equidistant DP cycle".
– Enter the times Ti and To (if not set at the master system under "Times Ti
and To identical for all DP slaves"). Recommendation: Accept the default
settings for Ti and To.
– Select the modules to be synchronized and, in the "Addresses" tab, assign
them to the subprocess image defined in the CPU.
DP Slave Properties
General Time Stamping
Synchronize DP slave with equidistant DP cycle (Ti / To identical for all slaves)
Time Ti (read in process values):
(min = 0.5000 ms; max =3.8750 ms)
Time To (output process values):
(min = 0.9375 ms; max = 3.8750 ms)
Equidistant DP cycle:
(min = 3.402 ms; max = 32.000 ms)

Note
If you click "Clock Synchronization" in the "Edit" menu, a configuration overview of
the clock-synchronized modules is displayed.
4. Create the user program:
– Create the OB 61.
– At the beginning of the OB 61, the SFC 126 must be called to update the
subprocess image of the inputs.
– At the end of the OB 61, the SFC 127 must be called to update the
subprocess image of the outputs.
– The subprocess image parameterized in the CPU ("Clock-Synchronized
Interrupts" tab) must be used as the subprocess image.
