(1) Setting OVERRIDE
OVERRIDE can be set as described below.
By using the [OVRSET] soft key, place the desired bit/byte in the
OVERRIDE state.
(a) Setting OVERRIDE on a bit–by–bit basis
Move the cursor to the desired bit, then press the [OVRSET] soft
key.
PMC SIGNAL FORCING OVERRIDE MONIT RUN
NO.76543210
X0000 000000 00
Then, the display changes as shown below.
PMC SIGNAL FORCING OVERRIDE MONIT RUN

(b) Setting OVERRIDE on a byte–by–byte basis
Position the cursor to the desired byte, then press the [OVRSET]
soft key.
PMC SIGNAL FORCING OVERRIDE MONIT RUN
NO.76543210
X0000 00000000
Then, the display changes as shown below.
PMC SIGNAL FORCING OVERRIDE MONIT RUN
NO.76543210
X0000 0>0 0>0 0>0 0>0 0>0 0>0 0>0 0>0
When OVERRIDE is set, the signal resumes the state existing
before OVERRIDE setting. When OVERRIDE is set for a pulse
signal, for example, the signal state existing when the [OVRSET]
soft key is pressed is overridden.
Each bit for which OVERRIDE is set has ”>” added in the status
display.
In OVERRIDE mode, those signal states that are not in the
OVERRIDE state are also displayed.
For an X signal:
(Input signal from the machine) 0 > 1 (input signal to the
ladder)
For a Y signal
(Output signal from the ladder) 0 > 1 (output signal to the
machine)
