4 Risk Reduction Design, Test, and Secure to Reduce Risks The applications that you create with the PLUS+1 GUIDE program typically control heavy, powerful, and mobile off-road equipment such as tractors, cranes, and harvesters. Using this type of machinery always involves the risk of personal injury and equipment damage even under normal operating conditions. Abnormal operating conditions greatly increase the risk of personal injury and equipment damage. The PLUS+1 GUIDE 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 You have the responsibility when you design a PLUS+1 GUIDE application to include the fault checking and the error handling needed to reduce risks in normal and abnormal operating conditions. The following are some items to consider when developing fault checking and error handling for your 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 %. 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. Test You have the responsibility once you have created an application to test the application. You should download your application to hardware and test its operation under both normal and abnormal operating conditions. You should make sure that: Individual inputs produce expected outputs. Fault handling and error checking work as designed. You must repeat your tests whenever you make configuration, calibration, or software changes to your application Rev CA December 2014

5 Risk Reduction Secure You have the responsibility to secure your application against unauthorized changes. You should 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 GUIDE Service Tool program to change your application s operating parameters. Changes in your application s operating parameters could cause unexpected machinery movement that result in personnel injury and equipment damage. Toolkey protection reduces the risk that unauthorized personnel could use the PLUS+1 GUIDE Service Tool 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 ) Rev CA December

6 Exp_Filter Function Block Overview Use the Exp_Filter function block as a first-order lag, low-pass filter that is specified by the time constant T1. The Exp_Filter function block provides filtering that can be used to reduce noise in an input or to slow down changes in a signal to give a less aggressive output. Typical uses for this function block include: Reducing random signal noise on an analog input. Slowing down the response in a digital control. Note that while an increase in this function block's T1 value can reduce signal noise, it can also reduce the response of the system. See: About Function Block Connections for an overview of this function block's connections and signals. About the Name Space Feature if you are using more than one of these function blocks in an application. Inputs Use only the data types specified in this table. Other data types cause compiler errors. Function Block Inputs Item Type Range Description ChkPt BOOL True include the function block s built-in Advanced Checkpoint with Namespace components in the compiled LHX download file. False exclude the function block s built-in Advanced Checkpoint with Namespace components from the compiled LHX download file. T1 U ,535 T1 (Time Constant) is the exponential function time constant. If T1 < Loop Tm, then the function block uses the Loop Tm as its T1 value. 1,000 = 1,000 ms. Bpas BOOL T Turns filtering off. Output = Input. F Turns filtering on. Output is determined by normal exponential function. Bpas (Bypass) disables the filter function and can be used to preset the output.

18 Soft_Ramp Function Block Overview Use the Soft_Ramp function block to provide a smooth transition from one value to another. The Soft_Ramp and the Time_Ramp function blocks output similar ramps. The ramps differ in that the Soft_Ramp function block adds soft acceleration and deceleration to its ramp. A typical use for this function block is in propel applications that require smooth starting and stopping. Note that the: Inc Tm parameter determines the ramp rate when the output increases in magnitude away from zero. Dec Tm parameter determines the ramp rate when the output decreases in magnitude towards zero. These parameter characteristics may cause a transition from one ramp rate to another when the Output crosses zero even if the Split input is false. See: About Function Block Connections for an overview of this function block's connections and signals. About the Name Space Feature if you are using more than one of these function blocks in your application Rev CA December 2014

36 Time_Ramp Function Block About the Name Space Feature If you use this function block more than once in an application, you must change each function block s Name Space value to avoid compiler errors. This function block contains one or more components that allocate memory using memory names ( aliases ). Identical function blocks have identical memory names. 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. How to Enter a Name Space Value 1. In the PLUS+1 GUIDE menu bar, click the Query/Change button. 2. Click the function block s page name to display the Edit Page window. 3. In the Edit Page window, enter a meaningful Name Space value. Name Space values are case-sensitive. 4. Press the Enter key. 5. Repeat these steps to enter unique Name Space values for other identical function blocks Rev CA December 2014
