Hi everbody. I am struggelig with read/send time to my Siemens PLC. I have made a flow, but it only work when i send a value with 2 decimals. Example: 13:13 - works fine. 18:56 - works fine 18:01 - Not working 10:07 - Not working. Attached is the flow. Can somebody help me what i am missing …

I can't test your flow at the moment, but show us what you see in the debug nodes for a good value and a bad value. From that you should be able to see which function is not working.

Hi Colin thanks for reply. I have discovered this in my function block function revertDecimalToDecimal(h, m) { const combined = "" + h + "" + m; const originalDecimalValue = parseInt(combined, 16); return originalDecimalValue; } let h = flow.get("inp3h"); let m = flow.get("inp3m"); …

Have a look at padStart(), though I see you are already using that in Function 44. By the way, it is a good idea to give your nodes meaningful names.

Thank you. I think the problem is that the "nummeric" block automaticly delete "0" so is make only "5" instead of "05" Any idea to fix that ?

[image] soerenbull: I think the problem is that the "nummeric" block automaticly delete "0" Do you mean the that the numeric node (they are nodes not blocks) shows numbers without leading zeros? Or do you mean the the number coming out of it hasn't got leading zeros? If the former then try,…

Allmost there now, i think :smiley: ... Can you tell me where to put the padstart in here in this function node? let inv=msg.payload ; flow.set("inp3m",inv); return msg;

To use padStart() you first have to convert the number to a string, so this should do what you want. let inv=msg.payload.toString().padStart(2, "0"); flow.set("inp3m",inv); return msg;
