Description
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.
