Automatic Single Statement (Mode 9) - Siemens SIMATIC S5 Manual

Executing Machining Programs
Note
grammed halt has priority.
In mode 8 ("automatic") an enter command is required for each "programmed halt".
The point at which the program is halted is always immediately before the next traversing
movement or dwell time.
In the following example, a number of unnecessary MOO functions have been used. Before ap-
proaching target 200, the enter command must be given three times although the interrupt point
is directly before the movement.

Automatic Single Statement (Mode 9)

This mode runs, in principle, in exactly the same way as automatic. However, you must supply
the "enter" command before a traversing movement or dwell time is executed. Only one tra-
versing movement or one dwell time in the machining program is executed, any further move-
ment or dwell time must be triggered separately. The break point is always immediately before
the next traversing movement or dwell time.
The command sequence with "automatic signal statement" is as follows:
BA 9 (automatic single statement); program number; start.
The axis changes to the "automatic single statement" mode.
The axis searches for the machining program with the specified program number.
Within the machining program the statements are executed until the first dwell time or first
traversing movement.
The axis then waits for the enter command.
BA 9 (automatic single statement); program number; enter
When the enter command is received, all functions are executed until the next traversing
movement or dwell time.
etc.
BA 9 (automatic single statement); program number; stop
With this command, the "automatic single statement" mode is interrupted. This can occur both
between the execution of two statements or during a traversing movement or dwell time.
