Appendix 1 Function Processing Time

This chapter describes the time required for processing functions when a single user
program using the bus interface functions or MELSEC data link functions (Q06CCPU-V
only) is executed with setting 100 as the task priority.
(1) Bus interface function processing time (Q06CCPU-V only)
POINT
The processing times of the bus interface functions and MELSEC data link
functions (Q06CCPU-V only) vary in some degree depending on the operation
conditions of the OS, the execution conditions of the user program, the mounting
position on the base unit, and the types of the modules mounted on the base unit.
The access times in the following tables are reference values for each function
processing time.
