5.2 Response times for the ET 200S
Calculating the response time with the IM151-1 STANDARD
The following equation enables you to make an approximate calculation of the ET 200S
response time:
Response time [μs]* = 28 ·
Explanation of the parameters:
● m: Sum total of all configured modules
● b: Sum total of all input and output bytes (without bit granular modules)
Example for calculating the ET 200S response time (as of 6ES7151-1AA05-0AB0)
Figure 5-2
Calculation method:
m = 21; b = 16
Response time = 28 ·
Response time = 28 · 21 +9 · 16 + 350
Response time = 1082 μs
