7.10 PROFINET system limits
Based on the devices, which have to communicate with the IO controller per ms, you can
determine the maximum number of devices. This also results in the maximum number of
configurable connections. The
Devices per ms
can be determined by the sum formula of
the individual refresh times (A).
D Devices per ms
n
Number of devices
A Refresh time device
Please note that the value D must always be rounded to the nearest
smaller integer!
The PROFINET IO controller has the following system limits
