Response times of the ET 200MP

Introduction
The response time of the IM 155-5 PN ST is made up of:
● the update time configured for the IM as IO device.
plus
● the backplane bus cycle time.
Backplane bus cycle time
The backplane bus cycle time is the time the interface module requires to output new output
data, read new input data and then copy it to the PROFINET send buffer.
The backplane bus cycle time in μs is made up as follows:
● (number of output data in bytes + number of output addresses) x 0.0668 + 1.6131
plus
● (number of input data in bytes + number of input addresses) x 0.0959 + 2.5901 (rounded)
plus
● Operating system processing time (500 μs).
