Viewing AKD’S Alarms on the AKI HMI Through PDMM
To view the AKDs alarms on the HMI AKI is necessary to register all alarms of each drive in the HMI Alarm Server and insert code in the PLC source program. This document teaches the use of import tables and PLC source program to facilitate the implementation of alarms in the control project.
Importing the alarm program to the PLC
The Alarm.xk5 file contains the code needed to display all alarms for one AKD drive in the HMI.
To import the program right click in Programs and select Import as shown below.
Select the Alarm.xk5 program and click Open.
In the Project Explorer double-click in Alarm to open the source code of the imported program. Click in Dictionary and expand the Alarm item.
In the program line 2 we have an instance of MCFB_AKDFault block. This block collects and provides the fault information entered in the block input parameter (Axis1 this example). The FAULT output becomes TRUE when the selected drive enters a fault state. The fault number returned by FaultNumber output is the same number as the drive AKD shows on its display. This block comes with missing information about its instance in the Dictionary when we import the program, so you must manually enter it. To do so click the Libraries tab and drag and drop the function, dropping it within the Alarm program source code as shown below:
Note that the instance of default in MCFB_AK Dictionary changed from red to black .
If there is more than one axis you can use the Inst_MCFB_AKDFault1  block to get the alarms for the additional axis.
The variable AKD1_AL_NUM  receives from the FaultNumber output from Inst_MCFB_AKDFault block the value corresponding to the active alarm number or 0 if there are no active alarms in Axis1 axis. For additional axes it is necessary to declare a variable for each additional axis. These variables are the type DINT and should have marked KVB field.
If the KVB field is not marked the variable will not be available for use in the HMI!
If there are no more axes, delete the text  program and the instance in the Dictionary .
The variable Ack_Alarms  will be used in the HMI to reset the alarms.
Preparing the table for import
Select the worksheet that have the desired language and delete the others.
Only if more than one axis:
In the chosen spreadsheet, the column Name contains a sequence name for the organization. There are 200 entries for each axis, so for a second axis the last entry will be Alarm0400.
The Text column contains the text that appears on the HMI with the occurrence of the alarm. Copy and paste the column itself by changing the text "AKD1 ..." to "... AKDx…" according to the drive number.
The DataConnection column receives the variable/tag that contains the value of the alarm. For the first axis use Tags.Alarm__AKD1_AL_NUM and the following axes "Tags.Alarm__" and the name chosen for the variable / tag declared in the PLC Dictionary.
The ExpressionName column stays in blank. All rows of ComparerType column are EqualTo value. The TriggerValue column has the value to be compared to the tag. Thus if the specified tag in DataConnection have the value corresponding to the active alarm number and it is equal to the value described by TriggerValue column HMI will show the text described by the column Text. All other columns should be adjusted according to the project specification.
Importing the table
The Alarm Server tab contains the data of all alarms that the HMI displays. To view it click Alarm Server  and a new tab will open:
Click in Import  to import the table prepared in the previous step.
In the Import Alarms window, you have to select Excel file in Import Module  and in  select the table.
Click Import when the wizard has finished loading the table.
Select the All Items option and click OK
If the import is completed successfully the following message will show:
Creating a button to reset the alarms
For a button on the HMI to acknowledge and reset the drive alarms you must create a button to do both actions. First disable the default buttons of the Alarm Viewer by clicking on it and General. Uncheck the button items as shown below:
Then create a button and in its actions configure as shown below:
