(4) Settings for low speed execution type program execution
(a) Program
Set the execution type to "Low speed" in the program of the PLC parameter dialog
box.
When using multiple low speed execution type programs, register them in the
order of execution.
(b) Setting of constant scanning, low speed program execution time and low
speed execution monitoring time
Set the time for constant scan and low speed program execution on the PLC RAS
setting tab of PLC parameter.
The constant scanning setting range is 0.5ms to 2000ms.
(Setting unit: 0.5ms)
The low speed program execution time setting range is 1ms to 2000ms.
(Setting unit: 1ms)
When watching the low speed execution type program execution time, set a low
speed execution monitoring time within a range of 10ms to 2000ms.
(Setting unit: 10ms)
POINT
When executing low speed execution type programs, be sure to set either the
constant scanning or low speed program execution time.
