[Rq.1120] PLC ready flag (R: M30000/Q: M2000)
• This signal is used to start the program control of the Motion CPU. When "[Rq.1120] PLC ready flag (R: M30000/Q:
M2000)" is ON, execution of the Motion SFC program, starting of axes by the servo program, and the synchronous control
operation can be performed.
• "[Rq.1120] PLC ready flag (R: M30000/Q: M2000)" can be switched OFF/ON by the following operation. However, turning
from OFF to ON of the "[Rq.1120] PLC ready flag (R: M30000/Q: M2000)" is ignored when the RUN/STOP switch is set to
"STOP" or during test mode.
(1) Switching with the RUN/STOP switch
• When the RUN/STOP switch is switched from "STOP" to "RUN", "[Rq.1120] PLC ready flag (R: M30000/Q: M2000)" turns ON.
• When the Multiple CPU system power supply is turned ON when the RUN/STOP switch is set to "RUN", "[Rq.1120] PLC ready flag (R: M30000/Q:
M2000)" turns ON.
• When the RUN/STOP switch is switched from "RUN" to "STOP", "[Rq.1120] PLC ready flag (R: M30000/Q: M2000)" turns OFF.
(2) Switching between RUN and STOP by remote operation
• Writing of parameters or files in the program from MT Developer2 is available while "[Rq.1120] PLC ready flag (R: M30000/
Q: M2000)" is OFF.
• When turning "[Rq.1120] PLC ready flag (R: M30000/Q: M2000)" from OFF to ON enables the program control of the
Motion CPU, "PCPU READY complete flag (SM500)" turns ON. Refer to the following for details of the processing when
"[Rq.1120] PLC ready flag (R: M30000/Q: M2000)" turns from OFF to ON, or from ON to OFF.
