Target list
This section describes the targets of the device/label access service processing setting.
Communication functions via the MC protocol
Among communication functions using the MC protocol, those to which the device/label access service processing setting
can be applied are as follows.
*1 Only the file register file can support it. (Other file access is always executed asynchronously from the program.)
*2 When registration/clear command is executed, it does not affect the scan time. However, since the serial communication module will
periodically access into the device memory of the CPU module when Function is enabled, it becomes the target for Device/Label access
service processing setting.
Applicable function Description
Functions to perform read/write to files accessed by programs When read/write is performed to the relevant files during execution of a
program, file inconsistency may occur. Therefore, such operation is performed
during the END processing.
Functions to perform write to devices/labels When write is performed to devices/labels during execution of a program, the
result of operation processing may become inconsistent. Therefore, such
operation is performed during the END processing.
