B.1 Response times of the ET 200MP
Interface module IM 155-5 MF HF (6ES7155-5MU00-0CN0)

Example calculation for case 1: The configured update time is greater than/equal to the
backplane bus cycle time.
• Configured update time is, for example, 750 μs
• Backplane bus cycle time = 510 μs
Result of case 1
Response time of the IM 155-5 MF HF = 750 μs + 510 μs = 1260 μs
Example calculation for case 2: The configured update time is less than the backplane bus cycle
time.
• Configured update time is, for example, 500 μs
• Backplane bus cycle time = 510 μs
Result of case 2
Response time of the IM 155-5 MF HF = 510 μs + (500 μs x (510 μs / 500 μs) + 500 μs) = 510
μs + (500 μs x 1 + 500 μs) = 510 μs + 1000 μs = 1510 μs
