Overview

The Tracer MP581 programmable controller is a general-purpose, input/ output device. The controller provides direct digital control of a variety of HVAC equipment.

The Tracer MP580 is factory-installed on Modular Climate Changer and on T-Series air handlers. The controller is factory wired to all sensors, actuators, valves, starters, and other items shipped with the air handler.

Use this programming guide to configure and program the Tracer MP580/

581.

Tracer MP580/581 plug-in

The Rover service tool is the setup and configuration tool for the Tracer MP580/581. It is analogous to PCM Edit for the PCM and UPCM Edit for the UPCM. For more information about the Rover service tool, see the Rover Operation and Programming guide (EMTX-SVX01E-EN).

To access the device through the Rover service tool, you must have the Tracer MP580/581 plug-in. The plug-in is a software file that Rover connects with internally to display information and set up configuration for the device. The plug-in also contains extensive online Help to help you access and change device information.

The Tracer MP580/581 plug-in can be run with Rover Version 4 and higher. You cannot run the Tracer MP580/581 plug-in with an earlier version of Rover. Updated versions of the Tracer MP580/581 plug-in may be released independently from the Rover software. Contact your local sales office for the latest versions of the Rover device plug-ins.

Viewing the status of binary and analog outputs

You can view the current status of each hardware output, binary and analog, on the Tracer MP580/581. The status table includes what is currently controlling the output. Valid control sources, in order of priority, are as follows (“None” is displayed if there is no control source):

• Operator display or Rover service tool (highest priority)

• Program within the Tracer MP580/581 controller

• Tracer Summit building automation system

To view the status of binary and analog outputs:

X In the Active Device View, click the BOs tab (Figure 4) for the status

of the binary outputs or the AOs tab (Figure 5 on page 6) for the sta-

tus of the analog outputs.

Overriding binary and analog outputs

You can override both binary and analog outputs. Upon override, the selected output value changes to the override value. The control source of the output becomes the operator display/service tool so that other control sources cannot change the value of the output.

Note:

Overrides are maintained through a power loss.

To override a binary or analog output:

1. In the Active Device View, click the BOs tab to view the binary outputs or the AOs tab to view the analog outputs.

2. Click the name of the output in the table that you want to override.

3. Click the Override button. The Override Binary Output dialog box (Figure 6 on page 7) or the Override Analog Output dialog box (Figure 7 on page 7) appears.

Viewing the status of binary and analog variables

Variables may be changed using a variety of methods. Variables can be communicated from the Tracer Summit system and changed using the Rover service tool. Variables may also be calculated in a program, or they may be made adjustable through the operator display. The Tracer MP580/ 581 accommodates 150 binary and 150 analog variables.

Tracer Summit variables 1 through 30 are reserved for use with the Tracer Summit building automation system. There are 120 variables controlled by the operator display/service tool and/or programs. These 120 variables are called local variables. You can view the status of each binary and analog variable.

To aid in troubleshooting, the status table includes the control source assigning the variable its value. For information on configuring binary

Changing binary and analog variables

Variables are often used for setpoints so that they can be changed by the building operator or owner from the operator display. In the Rover service tool, binary and analog variables can be changed from the Displays tab. To make a change from the Displays tab or from the operator display, the following must be true:

• The variable must be a local variable with the control source set to

the operator display/service tool. For information on configuring binary and analog variables, see “Configuring variables” on page 31.

• The variable must be designated as adjustable in the display configu-

ration. For information on setting a variable to be adjustable, see “Configuring custom displays” on page 41.

Note:

Variables cannot be changed from the home display on the operator display or in the Rover service tool.

Upon changing, the selected variable value changes to the requested value. The control source of the variable does not change, so other control sources, such as the operator display, can still affect the value of the variable.

To change a binary or analog variable in the Rover service tool:

1. In the Active Device View, click the Displays tab.

2. In the Display list, click the name of the custom display that contains the variable you want to change.

3. In the table, click the name of the variable you want to change.

Configuring the operator display

You can view custom displays from the Rover service tool as well as from the Tracer MP580/581 operator display. So, custom displays are useful even when the Tracer MP580/581 does not have a local operator display connected. In addition, a portable operator display temporarily connected to the device uses the custom displays.

Use custom displays to logically group the information available in the Tracer MP580/581. Seven custom displays are available. The first display is a home display that contains a name and two items. The home display name appears as the title on the operator display. You can also name the other six custom displays. Each custom display consists of four screens of four items, for a total of up to 96 items.

Within a custom display, assign each line to display an input, output, or variable. Leave a display item blank to break a display into subgroups. Custom displays allow you to group information by category or by equipment, rather than by point type. For example, all the information pertinent to the cooling tower may be shown on one custom display. Variables and outputs may be changed or overridden from the custom displays if the items are configured as adjustable.

Setting up occupancy inputs

The effective occupancy of the Tracer MP580/581 controller can be changed also by other inputs. A timed override is initiated by pressing the ON button on a Trane zone sensor. A timed override request changes the occupancy mode from unoccupied to occupied bypass. The controller remains in occupied-bypass mode until the bypass timer times out or the CANCEL button on the sensor is pressed.

Note:

Although the occupancy input override request affects the occupancy mode of the Tracer MP580/581 controller, programming is required for the equipment controlled by the Tracer MP580/ 581 to react to this request. See Chapter 8, “Using the Occupancy and PID blocks” for more information.

To set up occupancy inputs:

1. In the Active Device View, click the Schedule button. The Schedule dialog box appears.

Synchronizing time with Tracer Summit

Time synchronization of the Tracer MP580/581 controller with the Tracer Summit building automation system occurs automatically once a day or when the controller is powered up. The controller must be successfully communicating for the synchronization to occur.

Controlling the occupancy mode of the Tracer MP580/581

The occupancy mode of the Tracer MP580/581 controller can be controlled by the Schedule application, the operator display, a Rover service tool override, and the Tracer Summit system. Because there are several sources of control, there is an implied priority table. Table 2 on page 62 is a diagram of the priority list.

The highest priority is given to a request from the operator display or the Rover service tool. Both sources have the same priority level. The next highest priority is the building automation system (BAS), often the Tracer Summit system. The BAS request is initiated as long as all overrides from the operator display or Rover service tool have been released. Third on the list of priorities is the Tracer MP580/581 Schedule application local schedule.

The local schedule is used only if valid times are entered in the schedule table, and one of the following criteria is met.

• The controller is connected to an operator display (non-portable).

• Fifteen minutes have passed since the BAS lost communications.

• No overrides are present from the operator display or the Rover ser-

vice tool.

If there are no times entered in the schedule table and no schedule request is available, the fourth and fifth items in the priority list are the communicated occupancy sensor and the local occupancy sensor, respectively. The default to occupied is the lowest on the list of priorities. If nothing is controlling the device, the controller remains in occupied mode.

Manual command

If an occupancy override is requested, the occupancy information is communicated to the Tracer MP580/581 from the variable nviOccManCmd or as an override from the operator display or Rover service tool. This manual command takes priority over any other occupancy request. If the operator display is unplugged with an active override, the occupancy request remains in the override state. There is no time out, just as with nviOccManCmd.

If power is lost, the operator display override value is stored in EEPROM and is restored when power returns. This is not the same as nviOccManCmd. The value of nviOccManCmd is lost when power is lost and is Null when power returns.

CNT-SVP01C-EN 59

Chapter 4 Using the Schedule application

For more information about the manual command request priority, see Table 2 on page 62. For more information about network variable inputs, see Chapter 10, “Network variable bindings.”

Time schedule

Building automation systems normally communicate an occupancy request using the occupancy schedule input. The controller receives the communicated occupancy schedule from the network variable input nviOccSchedule. An occupancy schedule may also be communicated locally through the Schedule application. The local schedule could be from the week-day schedule or the exception schedule. The occupancy request from nviOccSchedule, sent from a BAS, takes priority over the local schedule.

For more information about the time schedule request priority, see Table 2 on page 62. For more information about network variable inputs, see Chapter 10, “Network variable bindings.”

Occupancy sensor

Some occupancy sensors may be equipped with the ability to communicate an occupancy mode to the controller. In such sensors, network variable input nviOccSensor is used to communicate occupancy to the controller. The controller must be using the SCC profile to use this variable.

For more information about an occupancy sensor request priority, see Table 2 on page 62. For more information about network variable inputs, see Chapter 10, “Network variable bindings.”

Occupancy binary input

A binary input on the controller can be used as an occupancy input if it is set up on the Occupancy Inputs tab in the Schedule application. For stand-alone controllers (any unit not receiving a communicated occupancy request, typically from a building automation system), the occupancy binary input determines the occupancy of the unit based on the hard-wired signal. Normally, the signal is hard-wired to a binary switch or time clock.

For controllers that receive a communicated occupancy request from a building automation system, the hard-wired occupancy binary input is used with a communicated occupancy request to place the controller in either occupied mode or occupied standby mode.

If both a hard-wired input and a communicated input exist, the communicated input is used. For more information about occupancy binary input request priority, see Table 2 on page 62.

60 CNT-SVP01C-EN

Controlling the occupancy mode of the Tracer MP580/581

Bypass timer

The bypass timer is set to the value in the Occupied Bypass Timer field every time the controller receives one of the following messages:

• nviOccManCmd = bypass

• Operator display override = bypass

• Timed override ON request from the local zone sensor (The zone sen-

sor ON button is pushed and released within 5 seconds.)

After the bypass timer is set to the value in the Occupied Bypass Timer field, it counts down to zero. The bypass timer is cleared every time the controller receives one of the following messages:

• nviOccManCmd = occupied, unoccupied, standby, or null

• Operator display override = occupied, standby, or null

• Timed override CANCEL request from the local zone sensor (The

zone sensor CANCEL button is pushed and released within 25 seconds.)

To disable the bypass timer, type 0 (zero) in the Occupied Bypass Timer field. This effectively disables the zone-sensor timed-override ON function, the operator-display schedule override-bypass enumeration, and the nviOccManCmd-bypass enumeration.

Note:

Although the bypass request affects the occupancy mode of the Tracer MP580/581 controller, programming is required for the equipment controlled by the Tracer MP580/581 to react to this request. See Chapter 8, “Using the Occupancy and PID blocks” for more information.

Table 2 shows the occupancy result of the hard-wired input, network inputs, or local schedule. The columns marked with a dash (—) represent inputs that are not considered in the occupancy arbitration.

Using the Calculations application

If there is a Tracer Summit system on the active link, use its totalization application to totalize pulse accumulations. If there is no Tracer Summit system on the active link, the Tracer MP580/581 plug-in includes the Calculations application that you can use to totalize pulse accumulations.

This application is easy to set up and apply to electrical monitoring, fluid flow, and other metering and monitoring functions. It can also be used to calculate runtime and starts for equipment. You do not have to do custom programming to calculate runtime. You can run up to six calculations. Use this application only for non-billing purposes.

Viewing the status of a calculation

In the Rover service tool, view the status of a calculation, including its name, type, current value, and units. You can also view the accumulated values for the calculation.

To view the status of a calculation:

X In the Active Device View, click the Application tab. The status of the

Tracer MP580/581 applications appears (Figure 41 on page 66).

CNT-SVP01C-EN 65

Chapter 5 Using the Calculations application

Figure 41. Calculations application status

Setting up a calculation

Set up the calculation name, input type, input, conversion factor, and units. Use the conversion factor and the units to make the value displayed in the Rover service tool more meaningful.

When you choose the input type, you also choose the calculation type. If an analog or pulse input is chosen, a totalization is performed. The calculation output is the sum of the pulse input values multiplied by the conversion factor. If a binary input type is chosen, the Tracer MP580/581 calculates run hours and starts. The output is incremented every minute a binary value is true. Starts are incremented every time a binary value changes from off to on.

To set up a calculation:

1. In the Active Device View, click the Calculations button. The Calculations dialog box appears (Figure 42 on page 67).

66 CNT-SVP01C-EN

Figure 42. Calculations dialog box

2. In the Name list, click the calculation you want to set up. The configuration information for that calculation appears.

3. If you want to change the calculation name, highlight the text and type a new name.

4. In the Input Type list, click the type of input you want the calculation to use.

This selection also controls what type of calculation occurs. If you select either an analog input or pulse input, the calculation type is a totalization. If you choose a binary input, Tracer Summit binary variable, local binary variable, or network variable input, the calculation type is total run hours and starts. See Table 3 for a list of the input types and their corresponding calculation types and available points.

Creating a graphical program

This chapter introduces the basics of Tracer graphical programming (TGP). Graphical programming consists of drawing a picture that represents data and logic.

Before you start to write a program, configure the inputs and outputs. For more information on configuring the inputs and outputs, see Chapter 3, “Configuring the Tracer MP580/581.” For more information on setting up the wiring, see the Tracer MP581 Programmable Controller Hardware Installation guide (CNT-SVN01B-EN).

Creating a new program

When the editor opens, a new, blank program appears. If a program is already open, or you want to open a new program, save the current program and then choose New from the File menu. A blank program appears in the design space (Figure 43 on page 72).

Note:

Only one program can be open in the TGP editor at a time.

Opening an existing program

To open an existing program:

1. From the File menu, choose Open. The Open dialog box appears.

2. Select the program you want to open.

3. Click Open. The program opens in the design space (Figure 50).

Figure 50. Equipment room exhaust fan program

CNT-SVP01C-EN 79

Chapter 7 Creating a graphical program

Editing program properties

The next step in writing a graphical program is to give the program a name and define some basic properties of the program. The properties of a program define how the program behaves. For example, Run Frequency is a property that defines how often the program executes. It is good practice to set the program properties before you begin to write a new program, but you can edit the properties at any time by opening the Program Properties dialog box.

To select the appropriate method of program execution, ask yourself the following questions:

• Is the program required to run at regular time intervals? If so, click

the Run Frequency option. Then specify the time interval in hours, minutes, and seconds.

• Is the program required to run on demand? If so, use the Event Trig-

ger option to provide the program with a reference to a universal input configured as a binary input or to a binary variable. When the binary input or variable changes state, the program runs.

• Is the program required to run only when the Tracer MP580/581 pow-

ers on? In this case, click the Start-up option.

To edit program properties:

1. From the File menu, choose Program Properties. The Program Properties dialog box appears (Figure 51 on page 81).

80 CNT-SVP01C-EN

Figure 51. Program Properties dialog box

Editing program properties

2. In the Program Name field, type a name for your program. The name may be up to 32 characters in length. Do not use spaces or

special characters except for an underscore in program names.

3. Type your name, project name, and phone number in the appropriate fields.

This information appears on the printout of the program.

4. Under Configuration, click one of the Run Frequency options.

Note:

When choosing Run Frequency, keep in mind that universal input status from expansion modules is updated every 2 seconds.

5. In the Number of Pages field, type the number of pages you need to draw your program.

The allowable range is one to five pages. You can always change the number if you find that you have too few or too many pages.

6. In the Program Description field, type a description of your program.

7. Click OK.

CNT-SVP01C-EN 81

Chapter 7 Creating a graphical program

Setting page width and size

The page size and layout you choose impacts the design space. For example, if you want to have a wider and shorter space, choose the landscape option. If you want to print your programs on 11 × 17 in. paper, choose that option.

To set page width and size:

1. From the File menu, choose Page Setup. The Page Setup dialog box appears.

2. Set the paper size, orientation, and margins. These settings apply to the TGP editor design space.

3. Click the Print Setup button. The Print Setup dialog box appears.

4. Set the paper size and orientation to implement these settings on paper when the program is printed.

5. Click OK. The Print Setup dialog box closes.

6. Click OK. The Page Setup dialog box closes, and the design space changes to the new setting.

Adding a block

To add a block:

1. From the Blocks menu, choose the type of block you want to add. See Figure 52 for an example. The cursor changes to a cross-hair (;) when over the design space.

82 CNT-SVP01C-EN

Editing block properties

2. Click in the design space to place the block. The block appears at the cursor location in the design space (Figure 53).

Figure 53. Input (Hardware) block

Editing block properties

A block is an object. In the TGP editor, you can edit the properties for objects, such as programs and blocks, by using their properties dialog boxes. Set the properties of each block as you place it in the program. This is especially important for blocks that can be set as analog or binary, because the connections between blocks are dependent on the data type, analog or binary.

To edit block properties:

1. Click on the block to select it. The block is outlined in yellow.

2. From the Edit menu, choose Properties. The properties dialog box for the block appears (Figure 54).

Note:

The properties dialog boxes for each block vary considerably depending on the options available for that block. Some blocks have no editable properties.

Moving blocks

To move blocks:

1. Press and hold the left mouse button on a block and then move the cursor (click and drag) to move the block to a new position in the design space. The block appears in the new location.

2. To select two or more blocks, press the Ctrl key while clicking to select blocks. The selected blocks are outlined in yellow.

Note:

You can also use a rubber-band selection to select more than one block. Click in the design space and drag the cursor so that the white line surrounds the blocks you want to select.

3. Click and drag the selected blocks to a new position in the design space. The blocks appear in the new location.

84 CNT-SVP01C-EN

Deleting a block

Aligning blocks

To align blocks:

1. Select two or more blocks. The last block selected is the controlling block, so all of the selected blocks align according to the position of the last block selected. The selected blocks are outlined in yellow.

2. From the Alignment menu, choose the alignment you want. The blocks align according to the selection.

Deleting a block

To delete a block:

1. Click on the block. The block is outlined in yellow.

2. From the Edit menu, choose Delete. The block and any wires connected to the block are removed from the design space.

Note:

To delete a block, you can also select the block and then press the Delete key.

Connecting blocks using wired connections

To use wired connections to pass data from block to block:

1. From the Blocks menu, choose Wire. The cursor changes to a crosshair (;) in the design space.

2. Hold the cursor over the output port of a block. The cursor changes from a simple cross-hair to a cross-hair with a square (Figure 56). This change in the cursor indicates that a connection may be made.

Note:

You may start wires on any block-input or -output port or on an existing wire. You cannot end a connection on a wire.

Figure 56. Cursor in wire mode over a valid connection

CNT-SVP01C-EN 85

Chapter 7 Creating a graphical program

3. Click on the output port of a block. A solid or dotted line appears between the connection point and the cursor.

Note:

A solid wire between blocks represents analog data being passed. A dotted wire between blocks represents binary data being passed. An analog-output port cannot be connected to a binary-input port, and a binary-output port cannot be connected to an analog-input port. Figure 57 shows the cursor that is displayed over an invalid connection.

Figure 57. Cursor in wire mode on an invalid connection

4. Click in an empty area of the design space to add a turn to the wire.

5. Move the cursor and click on an input port of a block. The wired connection is complete (Figure 58).

Figure 58. Analog wired connection

Connecting blocks using wireless connections

Use wireless connections to pass data from block to block when wired connections are impractical. In general, it is good programming practice to use an input in a program only once. By doing so, you will have an easier time debugging your program. By using the wireless connection, you can also prevent long and overlapping wired connections that are difficult to follow.

Figure 59 on page 87 is a sample program without wireless connections. Figure 60 on page 88 is the same program with two wireless connections added.
