I am trying to change the preset of a timer on delay through an HMI. I am doing everthing in simulation mode. I can get to the part where i click on the preset time to change it, and a num pad will appear. The problem is the preset time wont change when i hit ok on the numpad window.
to change a value from type TIME you must use the keypad because you must type in the IEC format like T#5s500ms. If you want to change a time value by using the visualization i suggest
use a INT variable
use in your Visualization this Variable
multiply the INT by 1000 (if you want to have seconds as unit)
use Typecast INT_TO_TIME
connect the result to the PT input of the timer
Hello Ralph Holz,
I'm new to Codesys and working on my first codesys PLC. I have a TP Timer and I want to be able to change and set the setpoint from my HMI. How do I go about using a INT variable and everything else you have on the list
