Execution Times
Resetting multiple state relays at one time and output disable
For output disability corresponding to emergency stop, follow “Cautions on safety” described in the PLC manual.
1) Resetting multiple state relays at one time by specifying a range
Resetting fifty-one state relays from S0 to S50 are reset time.
2) Disabling arbitrary outputs of state relays in the ON status
3) Turning OFF all output relays (Y) in a PLC
While the special auxiliary relay M8034 is ON, the sequence program is executed continuously, but all output
relays (Y) turn OFF. (These output relays are in the ON status in the monitor.)
Position of the MPS, MRD and MPP instructions
The MPS, MRD or MPP instructions cannot be used directly from a bus line in a state relay inside the STL.
Program MPS, MRD or MPP instructions after LD or LDI instructions as shown below.
