Calculation of the response time with the IM151-1 STANDARD and IM151-1 FO
STANDARD
The following formula enables you to make an approximate calculation of the ET
200S response time:
Response time [
m
s]* = 55 · m +110 · a + 400 · t + 190
* Parameter bus length > 1m: The response also increases by 40%.
Explanation of the parameters:
•
m
: Total number of all modules (power modules, digital electronic modules,
analog electronic modules, IQ-SENSE electronic modules, process-related
modules, and motor starters)
•
a
: Sum of all analog electronic modules, 4 IQ-SENSE electronic modules, and
1SSI fast electronic modules
•
t
: Number of all process-related modules (except 1SSI fast)
Note
The formula specified applies to cyclic data transfer. The following prerequisites
must be fulfilled:
•
No diagnoses are reported.
•
No modules are removed and inserted.
