Thanks for the heads up. This was not something I would have thought would be effected by being in a simulation. Frankly I thought the problem was me.

Hm, for same strange reason it's not work in simulation.
But it will works with real PLC (for example, CODESYS Control WIN V3).

But you can just do it by your code and of course it will works in simulation.

todOutput := TO_TOD(T#1H *  iInputHour + T#1M * iInputMinute);

It's pretty basic but I feel like I'm doing something wrong because I can't seem to get the TODConcat function from the CAA DTUtil library to work. I have used a few functions before and I had no problems then but...

¯\_(°_o)_/¯

PROGRAM Testing
VAR

    iInputHour:UINT;
    iInputMinute:UINT;
    todOutput:TOD;

    eError : DTU.ERROR;

END_VAR

todOutput := DTU.TODConcat(uiHour:=iInputHour, uiMinute:=iInputMinute, uiSecond:=0, uiMillisecond:=0, peError:=ADR(eError));

The reason I think I'm doing something wrong is that todOutput always equals TOD#00:00 which is what the documentation says the output will be in case of invalid inputs. The error code is always No Error (0)

I did try the example from the examples page on Codesys Help, same output. The example code is very similar to what I was thinking....

VAR

eError : DTU.ERROR;

todTime : TIME_OF_DAY;

END_VAR

todTime := TODConcat

(

uiHour := 5,

uiMinute := 4,

uiSecond := 3,

uiMillisecond := 2,

peError := ADR(eError)

);
