I am trying to write a value to a memory tag for testing purposes in an Ignition app development. I would like to a memory integer tag (TankLevel) to simulate Hi and Low level alarms. I've initially tried using a slider linked to the tag value, but couldn't get it to work. Any ideas?

If you make the binding bidirectional (turn on the "bidirectional" checkbox in the binding setup), you can have the slider write back to the tag.
