21.4 Master Memory Function

21.4.2 Before Turning on the Power
When the master memory cassette function toggle switch is ON (RTC + ROM) and the master
memory function is active, depending on the different modes when the power is ON, the
operation changes as follows.

When the power is turned on in PROG. mode
• When the power is turned on, change to the state indicating that data exists in all control
units and master memory units (program, comments, system register data, data register and
position register).
• Through the operation of the tool software, built-in memor y → ma ster memory transfer or
master memory → built -in memory transfer can be performed.
• When you copy the data saved in the control unit to the master memory cassette, turn on the
power in PROG. mode. When you switch to RUN mode, transfer the contents of the master
memory cassette to the built-in memory.

When the power is turned on in the RUN mode
• When the power is turned on, transfer the data saved in the master memory unit (program,
comments, system register data, data register) to the memory of the control unit.
• Data saved in the control unit before powering on will be overwritten.
• When the required data (program, comments, system register data, data register) has
already saved to the master memory, turn on the power in RUN mode.
KEY POINTS
• Perform the installation of the master memory cassette and the data
transmission from the control unit to the master memory cassette after the
setting and program editing are completed. Depending on the different
operating conditions, the following errors will occur.
