Danfoss | November 2018 AQ00000254en-000101

You must know and follow appropriate safety standards and specifications when developing a product.

Fulfilling standards and legal requirements results in several development needs — documentation,

development processes, organizational structures, and so on. All these needs have the goal to ensure a

certain product quality and safety. Meeting these requirements also makes your product development

process transparent and traceable for others.

The following are some items to consider when developing your application:

•

Review your specification of requirements, design, code and tests with peers.

•

Document decisions, actions, specifications, designs and reviews.

•

Assign the different roles to members of your team, such as programmer, tester, review team, and so

on.

•

Ensure the tester is a different person than the programmer.

•

Test all required functions, including functions in machines operating at extremes, on the target

platform.

•

Test all the required functions, including extreme situations and worst case scenarios, on the target

platform.

•

Implement life cycle and change management.

•

Ensure your documentation is complete, comprehensive, and understandable.

These considerations are necessary as a minimum. You may have additional considerations for your

application.

Safety Integrity Level

The PVED-CLS Hardware Function Block Library is designed to meet SIL 2 in accordance with IEC 61508

Ed. 3.

The OEM/customer is responsible for the overall functional safety specification, safety integrity level

requirement, implementation and validation of their application. Detailed analysis, review and

documentation for compliance to ISO 13849 or ISO 25119 must be done by the designer or integrator of

the safety related system.

The OEM/customer must select an appropriate PLUS+1

controller for the application. This selection

depends on the identified target risk reduction required for the application.

The function blocks in the library are unit tested and suitable for direct integration into the OEM/

customer target PLUS+1

GUIDE application software. Each function block is designed for signal

conversion and not for performing any safety functions.

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

The ErrCode input requires an input with a U8 data type.

2 If an incorrect data type is routed to the ErrCode input, then the compiler Error Message tab (with the error message generated by the

incorrect U32 data type) shows that a wrong type was chosen.

3 Compiler Error Message tab. The compilation does not finish.

All Blocks Have Companion Service Screens

All function blocks have P1D (PLUS+1 Diagnostic) files with companion Service Tool screens.

You can use these screens to simplify the task of creating PLUS+1

Service Tool screens for applications

that use PVED-CLS hardware function blocks. Refer to the PLUS+1 GUIDE Service Tool Design Manual

(Danfoss document number AQ00000160 for more information on how to create PLUS+1

Service Tool

screens.

The following figure shows the PLUS+1

Service Tool screen for a PVED-CLS function block. These screens

are typical of the PLUS+1

Service Tool screens supplied with function blocks.

You must set a function block’s Chkpt input to true to make a function block’s input and output signals

available to the PLUS+1

Service Tool program.

1. Right-click on Parameter Functions to open the dialog for importing service screens.

2. Select the service screen PFX file you want to import. In this figure, PVED_CLS_AUX_JOY_Msg.pfx is

selected.

3. The service screen is imported to the PLUS+1

Service Tool.

4. The service screen shows input, output and internal values to visualize the function block’s signal

flow. Input signals are located on the left side, output signals on the right side. In addition, the service

screen provides access to user-configurable operating parameters. They are always located in a

yellow panel.

5. Click Replace missing ECU in all log and parameter functions to replace the preset ECU “0,42 -

(Missing ECU)”.

Using the Replace missing ECU in all log and parameter functions feature is highly recommended

if service screens have been imported. Otherwise parameter pre-settings are lost. To use this feature,

make sure your ECU is connected to the Service Tool.

6. Select your ECU (here: 0,2 - WT) which replaces the missing ECU.

Import Service Tool Pages from the PLUS+1

GUIDE Library Tab Manager

In PLUS+1

GUIDE versions 8.1 and later, service screens (PFX files) and other documents can be stored in

libraries.

In the PVED-CLS Hardware Function Block Library for each module, the module itself (SCS file), the User

Manual, the Safety Manual and Programmer Guide and the service screen are stored under the

corresponding module – all in one place. Because of this change, use the following steps to import PLUS

Service Tool pages to the PLUS+1

Service Tool.

To use identical function blocks in the same application, perform the following steps.

1. Change the function block’s namespace values.

2. Change the prefixes of the names of the signals displayed in the function block’s companion PLUS+1

Service Tool screens if you want to use these screens.

Identical Function Blocks Need Different Namespace Values to Successfully Compile

If you use the same function block more than once in an application, you must change each function

block’s namespace value to avoid compiler errors.

All function blocks contain Advanced Checkpoint with Namespace components that enable the PLUS+1

Service Tool to read block input and output values.

Some function blocks contain non-volatile memory components that store function block operating

parameters.

Both these components use memory names (“aliases”) to allocate memory. Identical memory names

cause compiler errors.

The namespace value adds a unique prefix to each component name to avoid errors. Keep each

namespace value short to save controller memory.

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 PLUS+1

Service Tool screens to make the screens usable.

The input and output signals for blocks all have namespace prefixes. Danfoss configured the companion

PLUS+1

Service Tool screens to read signal names with these prefixes.

You must set a function block’s Chkpt input to true (which is the default value) to make the function

block’s input and output signals available to the PLUS+1

Service Tool program’s companion screens.

The following figure shows how a function block’s namespace value prefixes a signal name from the

function block.

Danfoss | November 2018 AQ00000254en-000101

Item Description

1 The namespace value for this block is now PVED_CLS_STW. All input and output signals from this function block now have a

PVED_CLS_STW_ prefix.

2 The PVED_CLS_STW_CP_Angle signal as it appears in the Design Screen (Advanced) window of the PLUS+1

Service Tool.

3 The Properties window that selects the PVED_CLS_STW_CP_Angle signal for display on the Engine Control Basic service screen.

Change Signal Name Prefixes with the Find and Replace Feature

You can simplify how you change name prefixes by using the Find and Replace feature.

Use the Find and Replace feature of the PLUS+1

Service Tool to change the namespace prefixes in PLUS

Service Tool signal names.

Refer to the PLUS+1 GUIDE Service Tool Design Manual (Danfoss part L1320837) for more information

about the Find and Replace feature.

Switching Between Different Parameter Sets

Schedule changes to parameter sets while the machine is in a safe state.

Warning

Do not change parameters while the machine is driving. Changing parameters while the machine is

driving could result in a dangerous situation. Before changing parameters, ensure that the machine is in a

safe state (for example, with standstill and neutral conditions) to prevent any harm to operators and

bystanders.

Fault of Input Signals

Input signals that do not use the full range of their data type are checked to determine if they are in the

allowed range.

If they are outside their range they are clamped to fit into their range. The Fault output displays a fault

code.

Value Fault

0x0000 OK, no fault.

0x8001 Input value too low.

0x8002 Input value too high.

Status of Parameters

A status output, rather than a fault output, is given for parameter faults where parameters are out of

range or where parameters are lacking order (for example, Src_Addr > 253).

If a parameter is outside an allowed range, the parameter is clamped to fit into the allowed range. The

allowed range is listed for every parameter in the individual function block’s user manual. The upper and

lower limit are always included as valid values.

Value Fault

0x0000 OK

0x8008 At least one parameter is out of its defined range or in the wrong order.

Using Identical Blocks in the Same Application

14 |

Danfoss | November 2018 AQ00000254en-000101

The following guidelines can help achieve good outcomes when using the same parameter in several

function blocks and when managing controller memory consumption.

Using the Same Parameter in Several Function Blocks

Sometimes the same parameter is needed in several function blocks.

Because such a parameter is placed independently in each function block where it is used, it has multiple

definitions without any automated alignment.

Recommendations for handling this are:

•

Remove the duplicated parameters and connect them to one common parameter block, so that the

value of the parameter is controlled from one central point.

•

Update the service screens.

Controller Memory Consumption

Every function block included in your application uses a certain amount of the controller’s memory.

Also, every checkpoint consumes a bit of memory. Depending on the amount of the controller’s memory

and the complexity of your application you might run out of memory.

If the controller runs out of memory, you can first remove unnecessary checkpoints to regain memory.

There are two ways to remove the function block’s checkpoints.

•

Delete single checkpoints inside the Checkpoints page on the second level.

•

Remove all function block’s checkpoints from the compiled code. This can be achieved easily by

changing the Chkpt input of the Checkpoints page from True (T) to False (F). After you recompile the

code, none of the function block’s checkpoints are included.

To integrate the checkpoints again, set the Chkpt input back to True (T) and recompile the code.

Be aware that some checkpoints include Status and Fault information. If you deactivate or delete them

you no longer see them on the service screen.
