FC-21 Flow Computer
11.7 View Tab
The View Tab screen allows for viewing selected group items on the PC in a similar
format as shown on the unit display. Data from the following groups can be viewed
in the List of Values section:
Process Parameters (i.e. rate, temperature)
Totalizers (i.e. total, grand total)
The setup software assumes the current setup has been uploaded from the flow
computer into the PC. It is important that the setup program and the FC-21 unit are
using the same setup information at all times or the data will be inconsistent. It is
best to upload or download the setup before using this feature.
To start the viewer, first check the boxes of items to view and then click the start
button. The data will appear in the appropriate sections and will be continuously
updated. The refresh rate is dependent on the number of items that are being
viewed and the baud rate of the connection. Data in the List of Values section can
be collapsed by clicking on the ‘minus’ sign in front of the group title. The data can
be expanded by clicking on the ‘plus’ sign in front of the group title. If a group is
collapsed and data in the group changes on refresh, the group will automatically
expand. Changing the view items requires stopping the current viewing, checking
the new selections and then restarting the viewer.
If communication errors occur while reading data from the FC-21 device, the word
‘Error’ will appear in place of the actual value. If the connection to the FC-21 is lost,
the viewer will time out with a message saying the device is not responding.
The viewer will attempt to communicate with the FC-21 device matching the device
ID set in the communications screen. If you are having trouble establishing
communication, compare settings for the PC and the flow computer. Also verify the
connections between the PC and flow computer.
