If a FROM or TO instruction is executed to the special function module
frequently with short scanning intervals, the special function module may not
be processed normally.
When you execute a FROM or TO instruction to the special function module,
adjust the processing time and conversion time using the timer, constant scan
and other measures of the special function module.
