Appendix 5
This section explains the time required for processing respective functions when a user program using bus interface
function, MELSEC data link function, and/or C Controller module dedicated function is executed with the task priority
set to 100.
Function specifications can be checked by using the following functions in Setting/monitoring tools for the C Controller
module.
