Introduction
All Blocks Have a Common Structure
Item Description
1. Outer page Provides:
Basic input and output connectivity for a work function block.
A wrapper for an inner page that contains a Logic page, a ChkPt page, and text with details about the block.
2. Name Space Blocks use memory names (“aliases”) to allocate memory. When you use the same block more than once in application,
your blocks need different Name Space values to prevent memory conflicts that cause compiler errors.
3. Chkpt input All work function blocks have Advanced Checkpoint with Namespace components.
T—includes the block’s Advanced Checkpoint with Namespace components in the LHX download file. Block
input and output signals are available to the Service Tool program.
F—excludes the block’s Advanced Checkpoint with Namespace components from the LHX download file. Block
input and output signals are unavailable to the Service Tool program.
Choose this option to produce smaller LHX files, which saves controller memory.
4. IO output Outputs a bus with all of a block's input and output signals.
This bus provides a convenient way to distribute a block’s signals to your application.
5. Status output
Fault output
Most blocks have a:
Status output that reports status conditions.
Fault output that reports fault conditions.

6. Inner page The page contains:
Explanatory text with details about the block.
A locked Logic page.
A ChkPt page.
7. Explanatory text Text on the inner page describes the:
General purpose of a block.
Purpose of each of the block’s inputs and outputs.
Data type of each of the block’s inputs and outputs.
Expected range of each of the block’s inputs and outputs.
Units of each of the block’s inputs and outputs.
Status and fault codes output by the block.
8. Logic page Contains a block’s operating logic. This is a locked page that you cannot enter.
9. ChkPt page Contains Advanced Checkpoint with Namespace components that can make all of a block’s input and output signals
available to the PLUS+1 GUIDE Service Tool program.
(To make these signals available, set a block’s Chkpt input to true before you compile your application.)

All Blocks Have Inputs that Require Defined Data Types
To avoid compiler errors, use only the data type specified for an input. These blocks do not
allow autotyped inputs.
Item Description
1. The Min4 input requires an input with a U16 data type
2. The correct U16 data type routed to the Min3 input.
3. The incorrect U32 data type routed to the Min4 input.
4. The compiler Error Messages tab with the error message generated by the incorrect U32 data type routed to the Min4 input.

Introduction
All Blocks Have Companion Service Screens
All blocks have P1D (PLUS+1 Diagnostic) files with companion Service Tool screens. You
can use these screens to simplify the task of creating Service Tool screens for applications
that use work function blocks. Refer to the PLUS+1 GUIDE Service Tool Design Manual
(Danfoss part L1219240) for more information on how to create Service Tool screens.
The following figure shows the Service Tool screens for an Antistall_CL function block.
These screens are typical of the Service Tool screens supplied with work function blocks.
T
You must set a control block’s Chkpt input to true to make a block’s input and output
signals available to the Service Tool program.
Item Description
1. P1P file The P1P file for the block.
2. P1D file The P1D file with the companion Service Tool screens.
3. Flow screen A Flow screen shows basic block values. Use Flow screens together to create Service Tool screens that show signal flow
through an application.
4. Detail screen A Detail screen shows all the input and output signal values of a function block. Use Detail screens to create Service
Tool screens that focus on individual blocks in an application.
5. Parameter screen A Parameter screen shows Flow screen values and provides access to a block’s user-configurable operating parameters.
Use Parameter screens to create Service Tool screen that enable users to view, change, and download block parameters.
Not all blocks have Parameter screens.

About the Organizational Scheme for the Service Tool Companion Screens
All companion Service Tool screens have a common color and organizational scheme.
The following figure shows a typical block and its companion Service Tool screen. The
tables that follow this figure describe the organization and color schemes used for
companion Service Tool schemes.
You should follow this scheme when using modifying companion Service Tool screens for
use in your own applications.
Item Description
1. Group information about blocks into panels.
2. Caption panels with the unabbreviated name of the block.
3. Use lighter Panel Colors for panel backgrounds.
4. Use darker Subpanel Colors for data elements such as log and parameter values.
5. Place block inputs on the left of side of panels.
6. Place block outputs on the right side of panels.
7. Place Status and Fault readouts with any explanatory text at the bottom of panels.

Introduction
About Using Identical Blocks in the Same Application
Perform these steps if you want to use identical blocks in the same application.
1. Change the block’s Name Space values.
2. Change the prefixes of the names of the signals displayed in the block’s companion
Service Tool screens if you want to use these screens.
Identical Blocks Need Different Name Space Values to Successfully Compile
If you use the same block more than once in an application, you must change each block’s
Name Space value to avoid compiler errors.
All blocks contain Advanced Checkpoint with Namespace components that enable
the Service Tool to read block input and output values.
Some blocks contain non-volatile memory components that store block operating
parameters.
Both these components use memory names (“aliases”) to allocate memory. Identical
memory names cause compiler errors.
The Name Space value adds a unique prefix to each component name to avoid errors.
Keep each Name Space value short to save controller memory.
Item Description
1. Duplicate Name Space values in identical function blocks cause a compiler error.
2. The compiler Error Messages tab with an Error 65 message generated by duplicate Name Space values.
3. A different Name Space value for each identical function block results in a successful compile.

Introduction
Identical Service Tool Screens Need Different Signal Name Prefixes to be Usable
If you use the same work function block more than once in an application, you must
change the signal name prefixes used in the companion Service Tools screens to make the
screens usable.
The input and output signals for blocks all have Name Space prefixes. Danfoss configured
the companion Service Tool screens to read signal names with these prefixes.
(You must set a block’s Chkpt input to true to make the block’s input and output signals
available to the Service Tool program’s companion screens.)
The following figure shows how a block’s Name Space value prefixes a signal name from
the block.
Item Description
1. The Name Space value for this block is Scaling. All input and output signals from this block have a Scaling_ prefix.
2. The block’s Input signal is available to the Service Tool program as Scaling_CP_Input.
3. The Scaling_CP_Input signal as it appears in the Service Tool program’s Design Screen (Advanced) window.
4. The Properties window that selects the Scaling_CP_Input signal for display in the Scaling window.

Introduction
The following figure shows what happens to companion Service Tool screens when you
change their blocksName Space values to enable a successful compile.
Item Description
1. The Name Space value for this block is now Scaling_1. All input and output signals from this block now have a Scaling_1_ prefix.
2. This block’s Input signal is now available to the Service Tool program as Scaling_1_CP_Input.
3. The Properties window selects the Scaling_CP_Input signal for display in the Service Tool screen for the Scaling_1 block.
4. No signals display in the Scaling_1 block’s Service Tool screen because the signal prefixes have changed from Scaling_ to Scaling_1_.
5. The correct selection to display the Input signal from the Scaling_1 block. You must reselect all the signals for this Service Tool screen.
6. The Name Space value for this block is now Scaling_2. All input and output signals from this block have a Scaling_2_ prefix.
7. This block’s Input signal is now available to the Service Tool program as Scaling_2_CP_Input.
8. The Properties window selects the Scaling_CP_Input signal for display in the Service Tool screen for the Scaling_2 block.
9. No signals display in the Scaling_2 block’s Service Tool screen because the signal prefixes have changed from Scaling_ to Scaling_2_.
10. The correct selection to display the Input signal from the Scaling_2 block. You must reselect all the signals for this Service Tool screen.
