The following table shows nominal programmer sweep impact times in microseconds (µs).

(µs)
The time required to open the Programmer Window but not process any requests.
The programmer is attached through an Ethernet connection; no reference values are
being monitored.
The sweep impact to refresh the reference table screen. (The %R table was used as
the example.) Mixed table display impacts are slightly larger. The sweep impact may
not be continuous, depending on the sweep time of the CPU and the speed of the host
of the programming software.
The sweep impact to refresh the editor screen when monitoring ladder logic. The
times given in the table are for a logic screen containing one contact, two coils, and
eleven registers. As with the reference table sweep impact, the impact may not be
continuous.
