5.3 Response time for digital input modules
IM151-1 HIGH FEATURE interface module (6ES7151-1BA02-0AB0)
66 Manual, 03/2008, A5E01075975-02
Explanation of the parameters:
● m: Sum total of all configured modules
● b: Sum total of all input and output bytes (without bit granular modules)

Figure 5-2 Example setup for calculating the ET 200S response time for the IM151-1 HIGH
FEATURE
Calculation method:
m = 17; b = 0
Response time [µs] = 16 + m + 9 + b + 160
Response time [µs] = 16 + 17 + 9 + 0 + 160
Response time [µs] = 432 µs
5.3 Response time for digital input modules
Input delay
The reaction times of the digital input modules depend on the input delay.
Reference
Information on the input delays can be found in the technical data of the
manual
for the
relevant digital electronic module.
