Difference in operation between PMC and PMC simulation
function

 

There are some differences in operations between PMC simulationfunction and actual PMC built-in CNC, because PMC simulationfunction executes ladder program by pseudo PMC function on PC.The different points of PMC and PMC simulation function are as follows

PMC Simulation function

 Execution of ladder
 The execution cycle time and timing of ladder are different
from actual PMC.
 Some error in timing at timers to count up may be caused by
the difference of running status between actual PMC and
PMC simulation function.
 The override function of signals cannot be used.
 Ladder execution order in multi-path PMC function is
different from actual PMC.
 In multi-path PMC function, the setting of the percentage of
ladder execution time is not effective.
 The following functions are not supported.
 PMC for dual check safety
 PMC/L for FS32i-A
To simulate the ladder for dual check safety and PMC/L forFS32i-A, convert its source files to one of supported PMC modelwith FANUC LADDER-III, and use the converted ladder for debugging

You can debug ladder that cooperates with CNC simulation function in CNC/PMC simulation function mode.
 Display and operation of CNC screen
 Ladder using the functional instruction related to CNC
 Ladder using the signals related to CNC (G, F)

 In PMC simulation function mode, the following functions are not
supported.
 Step sequence
 The functions available in CNC/PMC simulation function mode are as follow

Simulation function for PMC-SB7

Execution of ladder
 The execution cycle time and timing of ladder are different from actual PMC.
 Some error in timing at timers to count up may be caused by
the difference of running status between actual PMC and
PMC simulation function.
 The override function of signals cannot be used.
 The following functions are not supported.
 Step sequence
 Option parameter setting of CNC
 The ladder step option is fixed as 64,000 steps.
 Debugging ladder in cooperated mode with CNC simulation
function is not available on PMC-SB7

List of supported functions

The available functions in each mode of the PMC simulation function
are summarized in the next table
