Service Processing Setting

This function allows to set the time and the number of times of service processing performed at END processing by
parameters.
Processing for requests from peripherals to the CPU module are performed with this function. The processing speed
for the communication response to the requests varies depending on the scan time and communication load. Set the
parameter of the service processing time as follows to achieve an optimal service processing environment for the
system used.
• Setting a longer time can improve the processing speed for the communication response.
• Setting a shorter time can avoid a prolonged scan time caused by the service processing.
Communications from multiple peripherals to the CPU module may slow down the processing speed for the
communication response. Adjust the settings for the system by specifying a longer service processing time or
modifying the parameter settings of the peripherals to set longer timeout times taking the processing speed for the
communication response and increases in scan times into consideration.
● The service processing setting can be configured for the following communications:
• Communication via an intelligent function module (not including refresh with a network module)
• Communication via a USB cable, RS-232 adapter, RS-422/485 adapter, and the built-in Ethernet ports
(communication with a programming tool or GOT, or using the built-in Ethernet function)
● Using the COM instruction enables the service processing during program execution while the processing is normally
performed during END processing. Use this function when the scan time is long.
