M8000 Start Control
M8000 is used to control the operation of the CPU. The CPU stops operation when M8000 is turned off while the CPU is running.
M8000 can be turned on or off using the WindLDR Online menu. When a stop or reset input is designated, M8000 must remain on
to control the CPU operation using the stop or reset input.
M8000 maintains its status when the CPU is powered down. When the data to be maintained during power failure is broken after
the CPU has been off for a period longer than the battery backup duration, the CPU restarts operation or not as selected in
Configuration > Run/Stop Control > Run/Stop Selection at Memory Backup Error. For details on SmartAXIS Pro/Lite
start control, see "Run/Stop Selection at Memory Backup Error" on page 5-5.
M8001 1-sec Clock Reset
While M8001 is on, M8121 (1-sec clock) is turned off.
M8002 All Outputs OFF
When M8002 is turned on, all outputs and remote outputs go off until M8002 is turned off. Self-maintained circuits using outputs
also go off and are not restored when M8002 is turned off.
M8003 Carry (Cy) and Borrow (Bw) [Ladder program only]
When a carry or borrow results from executing an addition or subtraction instruction, M8003 turns on. M8003 is also used for the
bit shift and rotate instructions. For the causes of carry (CY) and borrow (BW), when ladder program is selected as the
programming language, see Chapter 4 "Instructions Reference" – "Carry and Borrow" in the "SmartAXIS Ladder Programming
Manual".
