3 Operating Characteristics
This section describes the operating characteristics of the Equipment.
3.1 Communications States
The Equipment represents the current state of its SECS link using a Communication Finite State Machine
diagram. The purpose is to make clear how this link is initiated and terminated.
The Communications State is displayed in the GEM status bar and the SECS/GEM tab of the Fluidmove
Run Window.
Initially, the INITCOMMSTATE variable is set to place the Equipment into the Disabled state at power-
up. Once Fluidmove has completed initialization, Fluidmove will change the Communications State to the
default communication state selected by the user. The loss of communications during Running or Pausing
will not affect the ability of Fluidmove to complete operations in the Process Program. However,
automatic reestablishment of the Process State may require manual intervention if Fluidmove has changed
state during the loss of communications period.
