Hi,

I'm using classicladder to connect modbus. there are some problems when i'm using it.

1st:When i use this config(didnt creat rungs yet):
loadrt classicladder_rt numRungs=150 numBits=20 numWords=2000 numTimers=10 numMonostables=10 numCounters=10 numSymbols=500 numPhysInputs=50 numPhysOutputs=50 numArithmExpr=500 numSections=4 numSymbols=500 numS32in=168 numS32out=100
If i increase numS32in > 168, then i cant set Bit Memory"%B". every plus 1, i lost 4 %B (like S32in = 169, then i cant set %B0-3)

2nd: When i start connecting 168 S32 Hal Pins (%IW) to Word memory(%W) by " ASSIGNMENT", i cant set "%Q" and "%B"

when you say you cant assign b3 how are you assigning it?
I tried this with out modbus and with 168 s32, I could set b3.

Can you this confirm?

sorry, i miss last two parameters. When i increase numFloatIn and numFloatOut , It 's fixed
