Program runtime/part counter (overview)

Information on the program runtime and workpiece counter are provided to support the
machine tool operator.
This information can be processed as system variables in the NC and/or PLC program. This
information is also available to be displayed on the operator interface.

Program runtime

Function
The "program runtime" function provides internal NC timers to monitor technological
processes, which can be read into the part program and into synchronized actions via the
NC and channel-specific system variables.
The trigger for the runtime measurement ($AC_PROG_NET_TIME_TRIGGER) is the only
system variable of the function that can be written to and is used to selectively measure
program sections. This means that by writing the trigger into the NC program, the time
measurement can be activated and deactivated.
600
: Asynchronous acknowledgement
"A"
The program execution is continued after the
command is issued. The acknowledgement
is stored in an acknowledgement variable
(pre-defined system variable) and must be
explicitly queried from the program. The
parameter following the acknowledgement
mode is the number of the acknowledgement
variable.
If no
<acknowledgement mode>
synchronous acknowledgement is used as default setting.
