Response times for the ET 200S
Calculation of response time with IM151-1 BASIC
The following formula enables you to make an approximate calculation of the
ET 200S response time:
Response time [
m
s] = 156 · m +33 · do + 486 · ai + 374 · ao + 1633 · t + 934
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)
•
do
: Sum of all digital output modules
•
ai
: Sum of all analog input modules and 1SSI fast electronic modules
•
ao
: Sum of all analog output modules
•
t
: Number of all process-related modules (except 1SSI fast)
