Step 6. Configure and Use Function Block Objects

  • Object configuration and use
  • General tab in a PPS Object dialog box.

Object Configuration and Use

Each PPS function block includes a faceplate and several mimic objects that are available for configuration and runtime use.

The function blocks are:

  • Advanced PID
  • AI
  • Analog Input
  • Analog Alarm
  • Discrete Alarm
  • AO
  • Analog Output
  • Control Status
  • DC2S
  • Device Control 2 State
  • DC3S
  • Device Control 3 State
  • DI
  • Discrete input
  • DOUT
  • Discrete Output
  • IND_A
  • HMI Analog Indication
  • IND_D
  • HMI Discrete Indication
  • HMI Manual Setpoint
  • HMI Discrete Pushbutton
  • PID
  • PID
  • Ramp Soak Setpoint Generator
  • Totalized Flow Rate

General Tab in a PPS Object Dialog Box

The General tab in the Object dialog box for PPS objects provides

  • Information about the class object on the EGD server.
  • The same type of information for all of the function blocks.
Field Description
Class ID Displays the name of the function block  that is associated with the object.
Description (Read-write) More information to help identify the object.
Class Version Version of the CIMPLICITY class that defines the object to keep track of changes in classes.
Block Version Version of actual function block (control logic)  in the PPS library.
Tag Name Given to the function block instance in the engineering workstation and carried through the PPS global name space
Tag Address OPC address: [$<OPC group>]<tag name> Group tags together to insure data coherency among instance data.
