How Objects Affect Behavior
OBJECT AFFECT ON BEHAVIOR
Identity Supports the Reset service. Upon receipt of a Reset Service
Request of any Type, the Identity Object sends a Reset
Service Request to the S-Device supervisor.
Message router No effect
DeviceNet™ Configures port attributes (node address, data rate and BOI
[Bus-Off Interrupt])
Connection class Contains the number of logical ports into or out of the device
Assembly Defines input/output and configuration data format
S-Device supervisor Supports the Stop, Start, Reset, Abort, Recover and
Perform_Diagnostic services for ALL Application Objects in
the device and consolidates the Exception Conditions and
Application Objects’ Status.
This object behaves differently from the Identity Object in
that the S-Device supervisor object provides a single point
of access to the Application Objects only; it does not affect
the DeviceNet™ specific objects (i.e., Identity, DeviceNet™,
Connection, etc.).
S-Sensor calibration Modifies the correction algorithm of the Flow S-Analog
Sensor object, which includes the selection mechanism to
enable an S-Sensor Calibration object instance.
S-Analog Sensor A virtual sensor determines the measured fluid flow rate.
The flow sensor feeds the process variable to the S-Single
Stage Controller object
S-Single stage controller Feeds the control variable to the S-Analog Actuator object
S-Analog actuator Operates the Flow Control Valve of the device
