.SH NAME
classicladder \- realtime software plc based on ladder logic
.SH SYNOPSIS
\fBloadrt classicladder_rt  [numRungs=\fIN\fB] [numBits=\fIN\fB] [numWords=\fIN\fB] [numTimers=\fIN\fB] [numMonostables=\fIN\fB] [numCounters=\fIN\fB] [numPhysInputs=\fIN\fB] [numPhysOutputs=\fIN\fB] [numArithmExpr=\fIN\fB] [numSections=\fIN\fB] [numSymbols=\fIN\fB] [numS32in=\fIN\fB] [numS32out=\fIN\fB]

.SH DESCRIPTION
These pins and parameters are created by the realtime \fBclassicladder_rt\fR module. Each period, classicladder reads the inputs, evaluates the ladder logic defined in the GUI, and then writes the outputs.

.SH PINS

.TP
\fBclassicladder.0.in-\fIN\fB\fR IN bit 
Connect a hal bit signal to this pin to use \fBB\fINN\fR in classicladder

.TP
\fBclassicladder.0.out-\fIN\fB\fR OUT bit 
Output from classicladder

.TP
\fBclassicladder.0.in-\fIN\fB\fR IN s32
Connect a hal s32 signal to this pin to use \fBW\fINN\fR in classicladder

.TP
\fBclassicladder.0.out-\fIN\fB\fR OUT s32 
Integer output from classicladder

.SH PARAMETERS

.TP
\fBclassicladder.0.refresh.time\fR RO s32
not sure what this does anymore

.TP
\fBclassicladder.0.refresh.tmax\fR RW s32
ditto

.TP
\fBclassicladder.0.ladder-state\fR RO s32

.SH FUNCTIONS

.TP
\fBclassicladder.0.refresh\fR FP 
The rung update rate. Add this to the servo thread.

.SH BUGS
The classicladder_rt module does not unload correctly.
