DBX0.3 Clear cancel alarms
Edge evaluation: No
Signal state 1 or Clear error key on the machine control panel is pressed.
edge change 0 → 1 All cancel alarms of the NCKs and the control panel are then acknowledged. The PLC application
acknowledges the PLC alarms itself.
PowerOn and Reset alarms remain active on the NCK until the cause of the error has been
removed.
Signal state 0 or Clear error key on the machine control panel is not pressed.
edge change 1 → 0
Functionality Only applicable to HMI Advanced or PCU 50.

DBX0.7 Actual value in workpiece coordinate system, 0 = machine coordinate system
Edge evaluation: No
Signal state 1 or The PLC selects the display of actual values in the workpiece coordinate system (WCS). This
edge change 0 → 1 means that when the machine area is selected, the WCS display is activated; i.e. the machine and
the supplementary axes as well as their actual positions and distances to go are displayed in the
WCS in the "Position" window.
The interface signal is only evaluated when it enters the basic machine screen; this means that the
operator, within the machine area, can toggle as required between the particular coordinate
systems using the softkeys "actual values MCS" and "actual values WCS".
Signal state 0 or This means that when the machine area is selected the coordinate system previously selected
edge change 1 → 0 (WCS or MCS) is reactivated and displayed.
Application Using the interface signal:DB19, DBX0.7 (actual value in WCS) = 1 each time that the machine area
example(s) is re-selected, the workpiece coordinate system display frequently required by the operator (WCS),
is selected.
