6.25.2 Service processing
(1) Service processing setting overview
The service processing setting specifies the number or time of service processing
executed in END processing as desired.
The service processing setting function can reduce increased scan time brought by
the improvement of communication response with the peripheral devices and service
processing. This enables to configure the service processing environment optimum
for the system.
POINT
Service processing designates the communication service processing with
peripheral devices (such as GX Developer) and intelligent function modules.
However, link refresh processing such as MELSECNET/H network module or CC-
Link network module is not included.
Using the COM instruction enables to perform service processing even during a midway
through program execution same as the one performed at END processing. Therefore, the
high-speed service processing response can be executed even if the scan time is long.
