Behavior On Block Search, Dry Run, Program Testing, Simulation - Siemens SINUMERIK 840D sl Programming Manual

Display functions of the measuring cycles
An HMI/PCU is required for showing the measuring result displays and measuring cycle
support.
Please observe the following when programming:
• Tool radius compensation is deselected before it is called (G40).
• All parameters for the cycle call have been defined beforehand.
• The cycle is called no later than at the 5th program level.
• The system of units allows measuring in the programmed unit system that deviates from

Behavior on block search, dry run, program testing, simulation

1.3
Function
The measuring cycles are skipped during execution if one of the following execution modes
is active:
• "Trial run"
• "Program test"
• "Block search"
Simulation
• On HMI Advanced ($P_SIM=1)
• On Jobshop products ($P_SEARCH=1 and $A_PROTO=1)
The measurements are simulated. No selected tool or zero offset is applied. Active functions
such as "measuring result display", "travel with collision monitoring", "measuring cycle
logging" are not executed.
Suppression of simulation execution
Execution of the measuring cycles in simulation can be suppressed in simulation by resetting
the variable _MC_SIMSIM=0 in data block GUD6. The measuring cycles are then skipped.
Specifying differences for simulation
The variable _MC_SIMDIFF of data type REAL permits specification of simulated
measurement deviations at measuring points. The value is a dimension in the basic system
of the control.

the basic system with switchable technology data.
– For metric dimension system with active G70, G700.
– For inch-based dimension system with active G71, G710.
($P_DRYRUN=1)
($P_ISTEST=1)
($P_SEARCH=1), only if $A_PROTO=0.
The measuring cycle programs are executed on selection of "Simulation" on the HMI.
