1.4.4 Clear PLC internal storage
 Erase PLC program
When the value of P.782 is written as 1, the inverter will clear the PLC program. After the clear is successful,
the value of P.782 will be restored to 0, and the value of P.782 will not be restored to 0 if the clearing fails.
The clearing procedure must be in the STOP state of the PLC, otherwise the clearing will fail.
 Erase power off keep part of the memory
When the special M relay M8032 is ON, the storage content of the latched area is cleared.
1.4.5 PLC component monitoring
P.783 selects the type of monitoring element, P.784 is the status of the current monitoring element.

For example, when P.783 = 5, P.784 = 4241, converted to binary is 0001000010010001, 16-bit bit from low
to high corresponds to the state of M0~M15, 1 is ON, 0 is OFF. Therefore, it can be seen that M0, M4, M7, and
M12 are in the ON state, and the others are in the OFF state.
