How to: Wonderware checks if tags are still connected

I would like to ask what will be your approach to show the connection status of your tags.

Lets say:
We have an image of motor
in FILL COLOR>ANALOG
STATUS 0 = GREEN (OFF)
STATUS 1 = RED (ON)
STATUS 2 = FAULT (I think its a signal from drive)

Now, how can we show that the motor/drive is disconnected or OFFLINE
I think It should be added as status. I ask if status 0 is for OFFLINE but it is for OFF status. HMMMMM....

Is this in intouch stand alone or in System Platform (ArchestrA)?

Stand Alone I think

The .QualityStatus and .QualityStatusString Fields

The .QualityStatus and .QualityStatusString Fields

The QualityStatus dot field is an integer value that displays the quality status of an I/O value, that is provided by an I/O Server when the I/O connection is valid. Associated with this dot field is the QualityStatusString dot field, which is the value of the QualityStatus field in a string (i.e., message).

.QualityStatus .QualityStatusString
0 Bad
1 Uncertain
3 Good


You can use a script to check these values and show that there is a communication error. so something like this Tag.QualityStatus = 0 or 1 means the tag is not being updated. Then do your error handling from there. In the past i have used black symbols to show there is a communication error. Easy to pick up by operators.

Hope this helps
