Basic Indicator On wiith decimal value

(1/1)

Nikola Tesla:
Good morning friends, I have been trying all day to turn on a BasicIndicator in red colour for example when the modbus register is at a decimal value of 101 and when it is at any other value the indicator is off. But something escapes me because as much as I try I don't get it. How could I do this?

 Thank you very much!

The PLCAddressSelectColor2 works on a boolean value, so you can program the comparison in your PLC to set a boolean value.

The other option is to use some code:

- Add a DataSubscriber to the form
- Set PLCAddressValue to the register you want to use
- Double click the DataSubscriber to get back to code
- Enter this code:

--- Code: ---if e.Values(0)=101 then
  BasicIndicator1.ForColor=Color.Red
else
  BasicIndicator1.ForColor=Color.White
end if

--- End code ---

Oh!! Thank you very much Archie for introducing me to the wonderful world of DataSubscriber!!!
