Edge evaluation: no
See DB21, ... DBX7.3 (NC STOP).
In addition, the spindles of the channel are stopped.
DB21, ...
DBX7.7 Reset
Edge evaluation: no
Signal state 1 or The channel is reset. The initial settings are set (e.g. G functions).
edge change The alarms for the channel are cleared if they are not POWER ON alarms.
0 → 1 The reset signal must be issued by the PLC (e.g., using a logic operation with the reset key on the
MCP). The signal is only evaluated by the selected channel.
The program status changes to "Aborted", and the channel status changes to "Channel status
reset".
Signal state 0 or No effect.
