FT View Basic Error

4 posts in this topic

Newbie here

 I am trying to do a basic factory talk View application. However, I am running into trouble using multi-state indicators to show the status of output bits. When I use multi-state Indicator for inputs it works fine but the output shows error on the indicator. When I look at the error it says it is the wrong size variable (O:o.o/1) for a digit tag assignment. This is the first time I have worked with FactoryTalk View studio so I am probably doing something stupid.

I don't like to directly address Inputs or Outputs;   FactoryTalk View has had some SNAFUs with the drivers, and in general I just don't like to risk the possibility that the HMI will write to something that the PLC is also trying to write to.

Is your multi-state indicator configured for 2-state (which could address a Bit) or Integer state (which would have to address a whole word) ?

Thank for the fast response

I set them for 2 states, state 0 = 0 & state 1 = 1.

I also set it for digital.

Note i tried both direct (o:0.0/0) & assignment to a Tag ( Output_1 = o:0.0/0)

Thanks

hi, i think your address syntax is wrong , just try this {::["Shortcut name"]O:0/0}
