objectives
Objectives
  • Introduce the MP580/581 Configuration editor
  • Introduce the Tracer Graphical Program (TGP) editor
  • Create a fan control program in TGP
tracer mp580 581
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
Program Properties
  • Always define program properties first
  • Properties include
    • program name
    • when program executes
    • program description
input and output blocks
Access the universal inputs

Controls hardware outputs

Input

Output

Input and Output Blocks
wire connector and wire

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 and Download
  • Build/compile
    • Error checking
    • Prepares for download
  • Download
    • new
    • replace existing
fan control
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
Logic Blocks
  • Output is true when:
    • OR = any argument is true
    • AND = all arguments are true
  • Expandable
check for fan failure
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
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
output status block

Fan Start Stop

Output Status Block
  • Read the state of an output
  • Choose analog or binary
  • No control is done
variables
Variables
  • Configuration
    • Tracer Summit
    • Local
  • Control source:
    • Tracer Summit
    • Operator Display / Rover Service Tool
    • Program
mp580 control choices
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 blocks1
Logic Blocks
  • NOT = assigns the opposite value
  • XOR = output is true when arguments do not match (mismatch)
