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.
9.16.1 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.
Time since the last control power-up
The timers for measuring the time since the last control power-up are always active and can be read via NC-
specific system variables:
Program runtimes
The timers for measuring the program runtimes are:
• only available in the AUTOMATIC operating mode.
• can be read via channel-specific system variables.
Some of the timers are always active, others can be activated / deactivated through MD parameterization.
The following system variables are available for the timers that are always active:
