2. DETAILS OF MIGRATION FROM Q17nCPUN(-T) TO RnMTCPU
(7) Switching of RUN/STOP status
The RUN/STOP status of Q17nCPUN(-T) is switched by directly operating M2000 (or M3072,
D704) in the program. However, the RUN/STOP status of RnMTCPU cannot be switched by
the same method.
Therefore, if M2000 is used to change the status, the program is required to be changed so
that a RUN contact for remote operation is used to switch the RUN/STOP status.
The following shows the procedure and point for the program revision.
[For Q17nCPUN(-T)]
Procedure Contents
1) Direct operation of M2000
(or M3072, D704) in the program
Changes CPU operation status.
[For RnMTCPU]
Procedure Contents
1) Set a RUN contact in the [CPU
Parameter] settings of
MELSOFT MT Works2
Set a X device for RUN contact (X0 to X2FFF)
2) Change the X device status CPU operation status can be changed by changing the
status of the X-device set in 1).
• RUN contact is OFF: CPU module is in RUN status.
• RUN contact is ON: CPU module is in STOP status.
During this operation, the RUN/STOP switch must be in RUN
position.
[Point]
- M3072 and D704 have become unusable in RnMTCPU. They cannot be used as a status device.
- Note that RUN contact ON is for STOP status and the RUN contact OFF is for RUN status.
