Graphical Programming Configuring & Programming Your MP580/581 T G P
Objectives • Introduce the MP580/581 Configuration editor • Introduce the Tracer Graphical Program (TGP) editor • Create a fan control program in TGP
Tracer MP580/581 • 25 point programmable controller • 12 Univseral Inputs • 6 Analog Outputs • 6 Binary Outputs • 1 Static Pressure Input • Use Rover service tool for configuration
Program Properties • Always define program properties first • Properties include • program name • when program executes • program description
Access the universal inputs Controls hardware outputs Input Output Input and Output Blocks
Fan Request Fan Start / Stop Fan Request Valve Output Valve Request Wire Connector and Wire Connection Port Dashed line = Binary data Solid line = Analog data
Build/Compile and Download • Build/compile • Error checking • Prepares for download • Download • new • replace existing
Turn the fan on if: the fan request input is on Freezestat is not tripped Turn fan off if: the fan request is off Freezestat is tripped Fan Control
Logic Blocks • Output is true when: • OR = any argument is true • AND = all arguments are true • Expandable
Review the sequence Add a fan failure check When a fan failure occurs: Shut down the fan Generate an alarm New blocks used: Output status Variable Feedback Alarm Check for Fan Failure:
Feedback Alarm Block • Compare the status of an input, output or variable to a requested state • Time based • Looks at input constantly • Request status • XOR • And not • Not and
Fan Start Stop Output Status Block • Read the state of an output • Choose analog or binary • No control is done
Variables • Configuration • Tracer Summit • Local • Control source: • Tracer Summit • Operator Display / Rover Service Tool • Program
MP580 Control Choices • Operator display/Rover • display and rover have the same “priority level” of control • act like a manual command • Program • only the program changes the value • Tracer Summit • allows control by tracer summit
Logic Blocks • NOT = assigns the opposite value • XOR = output is true when arguments do not match (mismatch)
