G Per submodule with 32 bytes of consistent data for the inte-
grated PROFINET IO interface
8 µs 30 µs
*)
In the case of I/O inserted into the central controller or expansion device,
the specified value includes the execution time for the I/O module
The module data is updated with the minimum number of accesses.
(example: 8 bytes result in 2 double word accesses; 16 bytes in 4 double word accesses.)
**)
Measured with IM460-3 and IM461-3 at a link length of 100 m
***)
Measured with modules with 1 byte of user data, e.g., DI 16.
The calculated cycle time of a S7-400H CPU must be multiplied by a CPU-specific factor.
The table below lists these factors:

CPU 410-5H stand-alone mode
Long synchronization cables may increase cycle times. This extension can have the factor 2
- 5 with a cable length of 10 km.
Operating system execution time at the cycle control point
The table below shows the operating system execution time at the cycle checkpoint of the
CPUs.
