d. Clear PLC Memory
This function clears the PLC user program memory. By this operation, the con-
tent of both the program created by the user, and the definitions data, are
deleted. The content of the flash memory, however, is not subject to this.
d.1 Select Mem Clear (M) from Control (C) in the System Configuration
menu.
d.2 Select the Yes (Y) button in the message box.
Note:
Execute this operation in the PLC run stop status. See “PLC Run Stop” above regarding
the stopping of PLC run.
e. Memory Compression
This function compresses the PLC user program memory. If the amount of user
programs is unusually large, and the user memory free space becomes small, the
free space of the user program memory becomes disconnected if there are
repeated program changes. For this reason, it is sometimes impossible to change
or add programs even if the necessary free space exists. At such times, it is pos-
sible to reduce the amount of user program memory space used, and to reconfig-
ure disconnected free space into connected free space.
e.1 Select Memory Compact (L) from Control (C) in the System Configura-
tion menu.
e.2 Select the Yes (Y) button in the message box.
Note:
Using the memory compression function, it is possible to create programs to the limit of
the user program memory. However, care must be exercised as it becomes impossible to
make changes to existing programs as the user program memory is used to its limit.
f. CPU Reset
This function rests the CPU. User programs within the CPU and configuration
data are not deleted in this operation.
f.1
Select CPU Reset (T) from Control (C) in the System Configuration
menu.
f.2 Select the Yes (Y) button in the message box.
Note:
Execute this operation with the PLC run stopped. See “PLC Run Stop” regarding the
stopping of PLC running.
g. Calendar Setting
This function sets the calendar values.
g.1 Select Calendar (D) from Control (C) in the System Configuration menu.
