Note: With shorter cycle times, the reaction times are further reduced and with longer cycle
times they are correspondingly extended.
Measurement results
From the following diagram, you can see the average values for the reaction time of the
cyclic interconnections depending on the size of the interface DB.
Legend:
The transfer frequency set in the parameters in SIMATIC iMap is as follows for the recorded lines:
1)
50 ms
2)
20 ms
3)
10 ms
Figure 2-3 Reaction times of the interface DB
Evaluation
From the diagram, you can see that the transfer frequencies configured at 10 ms or 20 ms in
the sample configured are not achieved. On the other hand, at a configured transfer
frequency of 50 ms, a corresponding reaction time of 50 ms with 2400 bytes is kept to.
Note
The values of the utilization parameters displayed by SIMATIC iMap as of V2.0 with the "Edit
/ Check utilization" function relate to the data exchange as
far as the CP. They do not apply
to data access from the user program.
