5.5.60. PAUSE
The PAUSE ON command is used to map an input bit to the pause function. While a
program is running, the interface scans the input bit. If the input bit value equals the
bitstate specified in the command, the pause function is called. This command is identical
to the “PAUSE” button on the UNIDEX 511 front panel. See Figure 5-7 for an example.
PAUSE OFF stops the scanning of the input bit. This command also can be used with the
iSBX-IO48 board.
