Complementary information
Changing the configuration logic or the hardware configuration changes the checksum.
7.2.2 Standard values for timing sets
Important information
WARNING
If the indicated application values do not correspond with the values of the target appli‐
cation, the standard values for the timing sets must be adjusted accordingly.

The four different timing sets can be selected sequentially using the Timing Set Selec‐
tion function. In the project file with a deactivated Timing Set Selection function, Timing
Set 1 is selected as standard.
Assumed application values
The standard values of the timing sets were calculated using the following application
values:
• Material length: 1,200 mm
• Conveyor speeds:
°
Timing Set 1: 0.1 m/s
°
Timing Set 2: 0.3 m/s
°
Timing Set 3: 0.5 m/s
°
Timing Set 4: 0.7 m/s
• Clock generator 0:
°
Clock period: 25 (= 100 ms)
°
Pulse time: 5 (= 20 ms)
• Clock generator 2:
°
Clock period: 1,500 (= 6 s)
°
Pulse time: 25 (= 100 ms)
All the data relate to a CPU cycle time of 4 ms. If the CPU cycle time is longer, the set‐
tings of the clock generators must be adjusted accordingly.
Complementary information
Changing the standard values of the timing sets changes the checksum.
