NAME

       classicladder - realtime software plc based on ladder logic

SYNOPSIS

       loadrt    classicladder_rt     [numRungs=N]    [numBits=N]    [numWords=N]   [numTimers=N]
       [numMonostables=N] [numCounters=N] [numPhysInputs=N] [numPhysOutputs=N]  [numArithmExpr=N]
       [numSections=N] [numSymbols=N] [numS32in=N] [numS32out=N] [numFloatIn=N] [numFloatOut=N]

DESCRIPTION

       These pins and parameters are created by the realtime classicladder_rt module. Each period
       (minimum 1000000 ns), classicladder reads the inputs, evaluates the ladder  logic  defined
       in the GUI, and then writes the outputs.

PINS

       classicladder.0.in-NN IN bit
              These bit signal pins map to %INN variables in classicladder

       classicladder.0.out-NN OUT bit
              These  bit  signal  pins  map  to  %QNN  variables  in  classicladder  Output  from
              classicladder

       classicladder.0.s32in-NN IN s32
              Integer input from classicladder These s32 signal pins map to  %IWNN  variables  in
              classicladder

       classicladder.0.s32out-NN OUT s32
              Integer  output  from classicladder These s32 signal pins map to %QWNN variables in
              classicladder

       classicladder.0.floatin-NN IN float
              Integer input from classicladder These float signal pins map to %IFNN variables  in
              classicladder These are truncated to S32 values internally. eg 7.5 will be 7

       classicladder.0.floatout-NN OUT float
              Float  output  from classicladder These float signal pins map to %QFNN variables in
              classicladder

       classicladder.0.hide_gui IN bit
              This bit pin hides the classicladder window, while still having the userspace  code
              run.  This  is  usually  desirable  when  modbus  is  used,  as modbus requires the
              userspace code to run.

PARAMETERS

       classicladder.0.refresh.time RO s32
              Tells you how long the last refresh took

       classicladder.0.refresh.tmax RW s32
              Tells you how long the longest refresh took

       classicladder.0.ladder-state RO s32
              Tells you if the program is running or not

FUNCTIONS

       classicladder.0.refresh FP
              The rung update rate. Add this to the servo thread.  You can added it to  a  faster
              thread but it Will update no faster than once every 1 millisecond (1000000 ns).
