GWGEM software maintains the GEM Control State finite state machine.
Fluidmove provides the following:
• GUI display of the current State.
• Provide Operator commands for Go Local and Go Remote.
• When ControlState is LOCAL, reject remote commands are appropriately rejected.
• When ControlState is REMOTE, reject local commands are appropriately rejected.
The current Control State is displayed in the GEM status bar in lower portion of all windows. In Remote
State configuration, teaching, and tools features are not available to the Operator. This prevents the
Operator form interfering with remote operations.
