I am building the screens for a Panelview 2711c-T6c using the built in emulator software. Will be talking to a slc 5/05. The screen I am working on now is to give operator option to select Fan1 run only, Fan2 run only, or run Both Fans (Cooling Tower). My problem is this! I am trying to use the "List Selector" button. I can't seem to make each display state have its own write tag. When I assign write tag it changes all three states to same tag. There are other tag options ie., Indicator tag, notify tag, handshake tag, visibility tag, of which I am not sure what they mean exactly. Should I use one of these instead of write tag in a "List Selector" button? I hope this makes some since to someone familiar with panelview. My first solo panel!


Thanks,

John

I am at home and left my panelbuilder software at work so the following comes from memory and not actual test.

All three states of the list selector go to the same write tag because that tag is meant to be an integer and each state places a different value into the integer.

For example:
Run Fan 1 Only would load a 1.
Run Fan 2 Only would load a 2.
Run Both Fans load a 3.

And your write tag might be N17:0.

This format would allow you to use N17:0/0 for Run 1 and N17:0/1 for Run 2 in your program.

Clear as mud I hope.

Thanks, I understand. It would be easier to just assign boolean tag for each selection in list. Must be a software reason why it can not be done that way. Waste a whole word for 2 bits!

Thanks again! What I ended up doing was changing the value in "List Selector" to 1,2, & 4 for the three selections. This gave me N7:0/0, 0/1, & 0/3 for elements.

New problem with the same screen. The two analog graphic displays on the screen shot above dissappear when the speed is zero. As soon as CT1 or CT2 start they reappear and display correct ACT. Speed of fan. Not really a big deal just can't put my finger on why this happening. Anybody got an idea?

Thanks,

John

Not really familiar with the new C pV's but check and see if you have a visibility parameter somewhere. Most likely visibility is set to greater than zero.

Thanks Bob,

I will look again when I get to work. The only thing I saw was the "visibility tag" which is blank. Not sure what this is for.Thinking maybe I should try pointing this to setpoint and change minimum to -1 instead of zero.

Try double clicking the gauge object (or click the 'Edit Properties' button under the Gauge properties section) - it looks like you can configure multiple needles and assign each one to a different read tag. That same window more settings for the gauge display stuff as well.
