The program execution cycle time depends on the following conditions.
Services Inner Board events (Single CPU
Systems or Process-control CPU Units
only)
Services file access (Memory Card or EM
file memory)
Services communications ports
• Type and number of instructions in the user program (in all cyclic tasks
• Type and number of Basic I/O Units
• Number of SYSMAC BUS Remote I/O Master Units and number of I/O
• Type and number of Special I/O Units, CS-series CPU Bus Units, Inner

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.
