hello,
After I able to read input register, I try to compare the input value but seem not work.
I setup the input comparator as Int32 representation.
See my picture.
How to do correct?

Hi Sony,

If you set representation to Int32 you will put the content of two registers into one Ii. I don't know if that is what you want.

The Modbus registers usually are Int16 and should be read by channels with representation Int16. The Ii.ActualValue though is Int32 so the register values will automatically be converted to Int32.

But the IGt shoud work regardless of this and looks as if the code for the IGt is not executing. Did the 'build node' succeed without error messages? Did you build the correct node? Did you restart runtime? Is the plc thread acually runnig (check the loopcounter in the PlcThread object) ?

I think not only comparison but all inststruction in the integer object pallete also can't work
I made a testing plc program from get starting document also not work. (see my attchment)

Please give me example lets say comparison with input from Getli instruction.

Hello,
I test logic programming like shown in "getting started guide" page 20 is work properly.
And I test analog programming like shown in "getting started guide" page 28 but not work. The result of 'ADD' instruction is always zero eventhough the input is not zero value.
Why the logic program work but analog program not work? whereas logic and analog in one program.

What wrong in my pwr55? please help.

Hi Sony.

Works with me (in pwr55), strange ?
It seems your PLC doesn't run. Is it connected to the 100ms Timer Thread ?

Hello,
I think my problem come from 'Build' step. It's not as usually that just one click all change compiled.
