4.4.1.3 Carrying Out One-shot Output

The one-shot type PLC interface signal forced output is forcibly output only once during the screen operations. Thus, it may
not be possible to confirm the PLC interface signals updated with the PLC on the screen.
One-shot outputting data "1" to device "X0042"
(1) Press the menu [1-shot output].
(2) Set the device and data, and press the [INPUT] key.
X0042/1 [INPUT]
Note
(1) Because the input signal (X, etc.) to the PLC is updated at the head of each PLC cycle, the machine immediately returns
to the normal state, even if one-shot type forced output is carried out.
(2) When no data is set (Example: "X0048/","X0048"), the operation message "Setting Data not found" is displayed.
(3) The X, Y, R, and ZR devices are one-shot output for all projects.
(4) The devices other than X, Y, R, and ZR are one-shot output for the currently displayed project.
CAUTION
Pay close attention to the sequence operation when carrying out forced data setting (forced output) in the I/F diag-
nosis screen during machine operation.
