7.10 PROFINET system limitsBased on the devices, which have to communicate with the IO controller per ms, you candetermine the maximum number of devices. This also results in the maximum number ofconfigurable connections. The Devices per ms can be determined by the sum formula ofthe individual refresh times (A).D Devices per msn Number of devicesA Refresh time devicePlease note that the value D must always be rounded to the nearestsmaller integer!The PROFINET IO controller has the following system limitsDevices per ms (D) Max. number of devices Max. number of configu-rable connections3 8 02 8 21 8 20 8 2O Output bytes per msn Number of devicesB Number output bytes per deviceA Refresh time per deviceThe PROFINET IO controller has the following system limits:n Max.
