Details
If a uniform peripheral servicing time
hasn’t been set in the PLC Setup for this
servicing, 4% of the previous cycle’s
cycle time (calculated in step (3)) will be
allowed for peripheral servicing.
If a uniform peripheral servicing time has
been set in the PLC Setup, servicing will
be performed for the set time. At least
0.1 ms, however, will be serviced whether
the peripheral servicing time is set or not.
If no Inner Boards are mounted, the ser-
vicing time is 0 ms.
If a uniform peripheral servicing time
hasn’t been set in the PLC Setup for this
servicing, 4% of the previous cycle’s
cycle time (calculated in step (3)) will be
allowed for peripheral servicing.
If a uniform peripheral servicing time has
been set in the PLC Setup, servicing will
be performed for the set time. At least
0.1 ms, however, will be serviced whether
the peripheral servicing time is set or not.
If there is no file access, the servicing
time is 0 ms.
If a uniform peripheral servicing time
hasn’t been set in the PLC Setup for this
servicing, 4% of the previous cycle’s
cycle time (calculated in step (3)) will be
allowed for peripheral servicing.
If a uniform peripheral servicing time has
been set in the PLC Setup, servicing will
be performed for the set time. At least
0.1 ms, however, will be serviced whether
the peripheral servicing time is set or not.
If no communications ports are used, the
servicing time is 0 ms.
