10.6.5 Remote latch clear
Remote latch clear is a function for resetting the latched device data of the QnACPU while
the CPU module is in STOP by using such as a GPP function.
(1) Application of remote latch clear
Remote latch clear is useful for latch clear operation when the CPU module is at the
locations below: In this case, the function is used in combination with the remote
RUN/STOP function.
• When the CPU module is installed in an inaccessible location
• When performing latch clear to the CPU module in a control panel from an external
source
(2) Methods for remote latch clear
Remote latch clear can only be performed by operation from GPP function or a serial
communication module.
• The operation using GPP function can be performed in the Remote operation of
the PLC menu in any mode.
• The control using a serial communication module is performed with the commands
in the dedicated protocol.
For details on serial communication module control, refer to the Serial
Communication Module User's Manual.
POINT
Remote latch clear cannot be performed when the CPU module is in RUN.
POINT
1. According to the device latch ranges set in "Device" in parameter mode, there
are ranges within which latch clear is valid and ranges within which it is not
valid.Remote latch clear is only valid for devices set in the range for which
"Latch clear valid" is set.
2. When remote latch clear is performed, devices that are not latched are also
cleared.
