Program Status - Siemens SINUMERIK 840D sl Function Manual

Commands
RESET-Command
The following Reset commands are available:
● DB11, ... DBX0.7 ("mode group reset")
● DB21, ... DBX7.7 ("Reset")
For a further explanation of the individual interface signals, please see
References: /FB1/ Function Manual Basic Functions; NC/PLC interface signals (Z1)
A RESET command can be used to interrupt an active part program or a part program block
(in MDA).
After execution of the Reset command, the interface signal DB21, ... DBX35.7 ("Channel status
Reset") is set.
The part program cannot be continued at the point of interruption. All the axes of the channel
go into exact stop unless they are in followup mode. The same applies to the spindles
configured in the channel.
The following actions are executed when the RESET command is triggered:
● Part program preparation is stopped immediately.
● Axes and, if they exist, spindles in the channel are decelerated along a braking ramp.
● Any auxiliary functions of the current block not yet output, are no longer output.
● The block indicator is reset to the beginning of the part program.
● All Reset alarms (channelspecific, axisspecific, spindlespecific) are cleared from the display.

Program status

The status of the selected program is displayed in the interface for each channel.
The PLC can then trigger certain responses and interlocks configured by the manufacturer
depending on the status at the interface.
The program status is only displayed in AUTOMATIC and MDA mode. In all other modes the
program status is aborted or interrupted.
Program states
The following program states are displayed at the NC/PLC interface (DB21, ... ):
● DB21, ... DBX35.4 ("aborted")
● DB21, ... DBX35.3 ("interrupted")
● DB21, ... DBX35.2 ("stopped")
● DB21, ... DBX35.1 ("waiting")
● DB21, ... DBX35.0 ("running")
A detailed description of the interface signals can be found in Section "Signals from channel
