To create calculated inputs and outputs
See information about the Station Builder application for information about creating calculated input and
outputs.
Warning:
Loss of system control and unexpected actuator movement can result from editing calculated
channel equations.
Unexpected high-force actuator motion and loss of system control can cause injury to personnel
and damage to equipment and specimens.
Do not attempt to edit calculated equations unless you fully understand calculated channel
concepts, the channel relationships in your system, and the result that making changes will have
to your system. Extreme caution is necessary and severe risks are involved. For final testing of
calculated equation changes, use a dummy specimen that is of no value to you.
How to Set Up a Virtual Channel
Use the following procedure as a guideline when setting up and using virtual channels:
1. Start the Station Builder application.
2. Select output hardware resources for each virtual channel.
For each virtual channel, select << Virtual Output>> for your output hardware resource.
3. Select input hardware resources for each virtual channel.
For your virtual channel, select an input hardware resource for each channel control mode.
4. Select required calculated outputs.
5. Select required auxiliary inputs (if any).
6. Start the Station Manager application.
The Station Manager application will display the Open Station window.
7. In the Open Station window:
a) Select the name of the desired station configuration file.
b) Click Open to open the desired configuration file.
8. Set Fullscale Min/Max values for each calculated input signal.
a) In the Station Manager window’s toolbar, select the Calibration access level.
b) Select Station Setup on the Station Manager Display menu.
c) Select a calculated input signal on the Station Setup navigation pane.
d) Select the Calibration tab on the Inputs panel.
