Risk Reduction
Design, test, and secure applications that you develop to reduce risks of personal injury and equipment
damage.
Design, Test, and Secure to Reduce Risks
Applications created with PLUS+1® GUIDE typically control equipment such as tractors, cranes, and
harvesters.
Using heavy, powerful, and mobile off-road equipment always involves the risk of personal injury and
equipment damage, even when this equipment is operating under normal operating conditions.
Abnormal operating conditions greatly increase the risk of personal injury and equipment damage.
The PLUS+1® program has no automatic protections against these risks. The tool has no protection
against the risks that result from bugs in the tool software, errors in the tool manual, or incompatibilities
between software versions of the tool.
You must:
•
Design your application to reduce these risks.
•
Test your application to reduce these risks.
•
Secure your application against unauthorized changes in its operating parameters to reduce these
risks.
Design
Test
As you design your application, you must include the fault checking and the error handling needed to
reduce risks in normal and abnormal operating conditions.
Consider the following when developing fault checking and error handling for your PLUS+1® GUIDE
application:
•
How the machine is normally used.
•
Possible operator errors and their consequences.
•
Industry safety standards and legal requirements.
•
Input and output failures and their consequences. These failures can include:
Joystick, sensor, and other inputs suddenly going to ±100 % or to 0 %.
‒
Joystick, sensor, and other inputs suddenly going to ±100 % or to 0 %.
‒
Outputs that control machinery direction, speed, and force suddenly changing direction or going
‒
to ±100 % or to 0 %.
Decide how likely each failure is. The more likely a failure, the more you need to protect against
the consequences of the failure.
•
The sequence of events and consequences of a fault or error.
•
The sequence of events and consequences of an emergency stop.
After creating an application, you are responsible for testing the application.
Download your application to hardware and test its operation under both normal and abnormal
operating conditions. Make sure:
•
Individual inputs produce expected outputs.
•
Fault handling and error checking work as designed.
You must repeat your tests when you make configuration, calibration, or software changes to the
application.

Risk Reduction
Secure
You have the responsibility to secure your application against unauthorized changes.
Always use the PLUS+1® GUIDE program’s Toolkey feature to restrict access to your application’s
operating parameters.
•
Without Toolkey protection, there is an increased risk that unauthorized personnel could use the
PLUS+1® Service Tool program to change your application’s operating parameters.
Changes in your application’s operating parameters might cause unexpected machinery movement
that results in personal injury and equipment damage.
•
Toolkey protection reduces the risk that unauthorized personnel could use the PLUS+1® program to
change your application’s operating parameters.
Refer to How to Use the Toolkey to Restrict Service Tool Access to Application Values in the PLUS+1—How-to
chapter of the PLUS+1 GUIDE User Manual (Danfoss part 10100824).

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.
Return the Input to the valid
range.

Change Namespace Value
To successfully compile your application, change the namespace value for function blocks that are used
more than once in an application.

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.

Change Namespace Value
To successfully compile your application, change the namespace value for function blocks that are used
more than once in an application.
1. In the PLUS+1® GUIDE menu bar, click the Query/Change button.
2. Click on the function block whose namespace you want to set to a unique value.
The Edit Page window opens.
3. In the Edit Page window, enter a meaningful Namespace value.
Namespace values are case-sensitive.
•
To save controller memory, use a short namespace value.
•
4. Press Enter.
5. Repeat these steps to enter unique namespace values for other identical function blocks.

When the PLUS+1® GUIDE compiler finds a function block that is incompatible with hardware, it aborts the compile
process and logs an error message. The error message gives the location of the function block and states “Error 80:
component not supported in hwd.”
