PROFINET Controller (PNC001) and PROFINET I/O Sweep Impact
The PLC CPU sweep impact for a PROFINET IO network is a function of the number of PNCs, the number
of PROFINET devices, and the number of each PROFINET device’s IO modules. The table below shows the
measured sweep impact of the RX3i PROFINET Controller, supported VersaMax PROFINET devices, and
I/O modules.

To calculate the total expected PLC sweep impact for a PROFINET I/O network, add the individual sweep
impact times for each PROFINET Controller, PROFINET Device, and PROFINET Device I/O module, using
the times provided above.
For example, for a PROFINET I/O network that consists of one PNC and one VersaMax PROFINET Scanner,
which has both an 8-point input and an 8-point output module:
Expected PLC Sweep Impact
= 50 (PNC) + 40 (PNS) + 23 (8pt. Input) + 18 (8pt. Output)
=131 µs.
