Function
•
Controls the input to the circuit sandwiched by the master control set (MCS n) and reset (MCR n).
(An AND operation is performed with respect to each input and MCS.)
•
The master control can be used up to eight layers.
( ) indicates the display when the Ladder Editor is used.
Notes
•
Always use the master control MCS and MCR in pairs.

Program description
X00000
X00001
Y00100
•
When input X00000 is on, the circuits surrounded by MCS and MCR obeys input X00001, and output Y00100 turns on/off.
•
When input X00000 is off, the circuits surrounded by MCS and MCR are independent of input X00001, and output Y00100
turns off.
