Start Of Part Program Or Part Program Block; Part Program Interruption - Siemens SINUMERIK 808D Function Manual

10.3.2

Start of part program or part program block

START command, channel status
The channel-specific IS "NC start" (DB3200.DBX0007.1), which is usually controlled via the following hardkey, starts
program processing.
The START command can only be executed in "AUTO" and "MDA" modes. For this purpose, the channel must be in the
"Channel status reset" (DB3300.DBX0003.7) or "Channel status interrupted" (DB3300.DBX0003.6).
Required signal states
The selected part program can now be enabled for processing with the START command. The following enable signals are
relevant:
IS "808D Ready" (DB3100.DBX0000.3)
IS "Activate program test" (DB3200.DBX0001.7)
IS "NC Start disable" (DB3200.DBX0007.0)
IS "NC Stop at block limit" (DB3200.DBX0007.2)
IS "NC stop" (DB3200.DBX0007.3)
IS "NC Stop axes plus spindle" (DB3200.DBX0007.4)
IS "EMERGENCY STOP" (DB2700.DBX0000.1)
Axis or NCK alarm
Execution of command
The part program or part program block is automatically processed and IS "Channel status active" (DB3300.DBX0003.5)
and IS "Program status running" (DB3300.DBX0003.0) are set.
The program is processed until the end of the program has been reached or the channel is interrupted or aborted by a STOP
or RESET command.
Interrupts
The START command is not effective if the prerequisite is not fulfilled. Then one of the following interrupts occurs: 10200,
10202, 10203
10.3.3

Part program interruption

Channel status
The STOP command is executed only if the channel concerned is in the "Channel active" status (DB3300.DBX0003.5).
STOP commands
There are various commands which stop processing of the program and set the channel status to "interrupted":
● IS "NC Stop at block limit" (DB3200.DBX0007.2)
● IS "NC stop" (DB3200.DBX0007.3)
● IS "NC Stop axes plus spindle" (DB3200.DBX0007.4)
● IS "Single block" (DB3200.DBX0000.4)
● Programming command "M0" or "M1" and corresponding activation
Execution of command
After execution of the STOP command, IS "Program status stopped" (DB3300.DBX0003.2) and the IS "Channel status
interrupted" (DB3300.DBX0003.6) are set. Processing of the interrupted part program can continue from the point of
interruption with another START command.
