classicladder − realtime software plc based on ladder logic |
|
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] |
|
These pins and parameters are created by the realtime classicladder_rt module. Each period, classicladder reads the inputs, evaluates the ladder logic defined in the GUI, and then writes the outputs. |
|
classicladder.0.in-N IN bit |
|
Connect a hal bit signal to this pin to use BNN in classicladder |
|
classicladder.0.out-N OUT bit |
|
Output from classicladder |
|
classicladder.0.in-N IN s32 |
|
Connect a hal s32 signal to this pin to use WNN in classicladder |
|
classicladder.0.out-N OUT s32 |
|
Integer output from classicladder |
|
classicladder.0.refresh.time RO s32 |
|
not sure what this does anymore |
|
classicladder.0.refresh.tmax RW s32 |
|
ditto |
|
classicladder.0.ladder-state RO s32 |
|
classicladder.0.refresh FP |
|
The rung update rate. Add this to the servo thread. |
|
The classicladder_rt module does not unload correctly. |
