Siemens AG 2018 All rights reserved 1 Introduction 1 Introduction 1.1 Overview Initial situation Requirement Identification and maintenance data (in short: I&M) are stored internal component (firmware and / or hardware) of a device with PROFINET interface. The I & M data sets can be read out via an acyclic data exchange with "Read/Write Record". The I & M data enable the unique identification of the devices and modules and their versions. Any device that can be replaced or updated for maintenance and repair needs to be uniquely identifiable online. Problem Solution A machine, e.g. a complete machine tool or a laser welding machine, usually consists of substations with dedicated automation components. Some of these automation components are not part of the PROFINET system and therefore cannot be addressed via PROFINET. These lower-level automation components cannot be uniquely identified because the I & M data is only available for devices or modules that can be addressed via PROFINET. To solve this problem, Management (short: AM)" has been introduced. In addition to I & M, asset management is an additional concept for providing information such as via firmware or hardware versions, from locally connected devices or driver versions outside the PROFINET address space. management is based on I & M and works with a standardized data set, the Management Record (short: AMR)". Applicative implementation This application example shows you how to use the identification and maintenance functions I&M and AM. On the hardware side, a SIMATIC S7-1500 is operated as an I-device. The SIMATIC S7-1500 is equipped with several central I/O and communication modules. Other devices that are not located in the PROFINET address space, e.g. sensors, actuators and motors, are subordinated to these central modules. The software includes the function block "Management", which is loaded into the I-device and which you can find in the application example. The function block creates an asset management record from all calculated (I&M) and individual (AM) information and makes this data record available to the IO controller.

Siemens AG 2018 All rights reserved 1 Introduction Figure 1-1 I-device with central modules I&M AMR S7-1500 Non-PROFINET component Non-PROFINET component AM Advantage The use of the identification and maintenance functions I&M and AM has the following advantages: All components in an automation system are completely recorded: I&M for PROFINET devices AM for hardware and software outside the PROFINET address space Every item of hardware or software is clearly identifiable. You always have an overview of all the hardware and software installed in your network. Conclusions can be drawn about a possible malfunction or unsupported functionality in a field device.

Siemens AG 2018 All rights reserved 1 Introduction 1.2 Mode of operation 1.2.1 management Terminology The following terms are used in connection with the asset management function: Table 1-1 Term management block Management Record Explanation A component or object in an automation network. This can be a module, a device, the firmware or a driver, for example. The information about the asset is stored in an asset management block. The asset management block contains all the identification and recognition data for an asset. All asset management blocks are combined in one asset management record. The asset management record is a data record with the index 16#F880. Description With asset management it is possible to provide identification and recognition data for assets that are not part of the PROFINET network. The user creates an asset management block for each non-profinet component and stores the identification and recognition data of the asset here. The asset management blocks are then combined into an asset management record. The asset management information for assets that cannot be addressed via PROFINET is managed and stored by the PROFINET device to which these assets are connected (in the case of an intelligent PROFINET device) or a higher-level PROFINET CPU. 1.2.2 Application Procedure The application in the I-device uses I&M and AM to provide the information about the assets to an IO controller. To identify the individual assets, the following procedure applies: The I&M data of all modules inserted centrally in the I-device are automatically read and processed for asset management. You specify the information about the assets outside the PROFINET address space, e.g. sensors and actuators, individually and enter this information in pre-built asset management block structures. The application creates an asset management record from all determined and individual information and makes it available to the IO controller. Entry ID: 109748894, V1.0, 05/2018 6

Siemens AG 2018 All rights reserved 1 Introduction Explanation Table 1-2 Step The following table describes the individual steps from the schematic diagram: Description 1. You specify the information about the assets that are outside the PROFINET address space individually. You store the information in ready-made asset management block structures and transfer it to the "Management" function block as the input parameter. The function block "Management" reads the blocks and processes them. 2. The information about the assets that is stored centrally in the SIMATIC station is automatically determined by the "Management" function block using the "Get_IM_Data" application and converted into individual asset management blocks. 3. The asset management function block generates an asset management record from all asset management blocks. This record therefore contains this information: Information about the assets outside of the PROFINET address space (individually determined by you). Information on the centrally plugged modules in the I-device (automatically determined by I&M). 4. The asset management record is made available to the higher-level IO controller via the system application "PRVREC" and the index 16#F880. 5. The higher-level IO controller reads the record via the system application "RDREC". Delimitation This application example only contains the configuration for the I-device. If you want to read and receive the asset management record in the higher-level IO controller, you must request the data record in the IO controller with the system application "RDREC" and the index 16#F880 from the I-device.

Note The controller for the IO device must have at least firmware 2.5.2. 2.2 Configuration For the I-device to react to the asset management, you must activate the asset management in the I-device. You will find the corresponding check box in the menu item "Operating mode" in the properties of the CPU. The "Operating mode" dialog has been extended by another entry "Activate asset management via the user program". If you select this check box, you signal that the application program responds to requests when retrieving asset management data. Entry ID: 109748894, V1.0, 05/2018 10

Siemens AG 2018 All rights reserved 2 Engineering Figure 2-2 Note The check box can only be activated if you have set the operating mode to "IO device". 2.3 User program This section gives you an overview and description of the blocks in the user program. 2.3.1 Data types Description Each asset management block describes an asset. To describe the asset, there are three different formats of the asset management block: Complete information (consisting of hardware and firmware information) Only hardware information Only firmware information The organization and the structure are each firmly defined and may not be changed. To assist you in entering the asset information, the application example provides a separate data type for each asset management block format. The following table shows you which data type corresponds to which asset management block format: Table 2-1 management block Full information Only hardware information Only firmware information Data type typemanagementfullinformation typemanagementonlyhw typemanagementonlysw Entry ID: 109748894, V1.0, 05/2018 11

Siemens AG 2018 All rights reserved 2 Engineering The figure below shows you as an example the data type "typemanagementfullinformation". This data type reflects the asset management block format "Full Information". Figure 2-3 Note You can find further information on the asset management block in Section 3.1.2. Entry ID: 109748894, V1.0, 05/2018 12

Siemens AG 2018 All rights reserved 2 Engineering 2.3.2 Data blocks " Data" The "Data" data block is the location for the asset management blocks that you store for your assets. As required, you define your own array tag for each asset management block format in the data block and assign the associated data type to this tag as a type. The array size of the arrays depends on the number of assets you want to describe in this format. The following figure shows an example of how the data block can be declared with array tags. Figure 2-4 For the example shown, the following statements are correct: Two different asset management block formats are used "Full information" (referenced by the data type "typemanagementfullinformation") "Only hardware information" (referenced by data type "typemanagementonlyhw") Three assets are described in the "Complete Information" format. One asset is described in the "Only hardware information" format. No asset is described by the Management block "Only firmware information". " Management Record" The "ManagementRecord" data block consists of a single tag, which is declared as a byte array. The "Management" function block generates the asset management record in this byte array. Note The byte array is declared with a size of 20 kbytes. You can change the size using the user constant "#MAXDATA". Entry ID: 109748894, V1.0, 05/2018 13

Siemens AG 2018 All rights reserved 2 Engineering 2.3.3 Function block "Management" Core task The core task of the " Management" function block is to create an asset management record from all information (I&M data, AM) and to make this data record available to the IO controller. Note You will find a detailed description of how the block works in in Section 3.2. Interface description The following figure shows you the how the function block "Management" is called.

The referenced array must be of the type "typemanagamentonlysw" (see Section 2.3.2). If no array exists, NULL must be parameterized. IN_OUT Version Reference to the array for the asset management block "Only hardware information". The referenced array must be of the type typemanagamentonlyhw" (see Section 2.3.2). If no array exists, NULL must be parameterized. Note If the block detects a discrepancy in the parameter checking or if a system application detects an error, the block issues an error. You can recognize the cause of the error by the parameter "status" (see Section 2.5). Entry ID: 109748894, V1.0, 05/2018 15

Siemens AG 2018 All rights reserved 2 Engineering 2.4 Operation This Section shows you how to use the asset management feature. Storing asset information To store information about the non-profinet components, proceed as follows: 1. Open the data block "Data". 2. Declare an array tag for each asset management block format and specify the associated data type as the data type, for example, typemanagementfullinformation for the "Full information" format. The array size of the arrays depends on the number of assets you want to describe in this format. Note: Tags have already been created in the data block. You can change, delete or add these as you like. Example: 3. Open the array fields and fill in the data type with information about the asset. Each asset is represented by its own array field element. Note For a description and information on the wiring of the tags of the asset management block, see Section 3.1.2. Entry ID: 109748894, V1.0, 05/2018 16

Siemens AG 2018 All rights reserved 2 Engineering Connect " Management" block Interconnect the array tags from the data block "Data" with the function block "Management". Follow these steps: 1. Open the "OB1". The function block "Management" is called here. 2. Interconnect the IN and OUT parameters, e.g. with a flag. 3. Interconnect the following IN-OUT parameters of the function block with the array tags from the "Data" data block: Table 2-3 IN-OUT parameters arrayforblockfulinformation arrayforblockonlysw arrayforblockonlyhw Array tag from "Data" Array tag of data type "typemanagementfullinformation". Array tag of data type "typemanagementonlysw". Array tag of data type "typemanagementonlyhw". Note If you do not use an IN-OUT parameter of the function block, you reference a NULL pointer (value "NULL"). Final steps 1. Save and compile the project. If there are errors during compilation, fix them. 2. Download the project to the CPU. All modules must be in a faultless condition. Test application example To test the application example, proceed as follows: 1. Trigger the IN parameter of the "Management" function block with a positive edge. 2. If the function block has read in all the information (I&M data, AM) without errors and has converted it to an asset management record, the OUT parameter "dataconsistent" is set. The asset management record is made available to the higher-level IO controller with the system application "PRVREC". 3. Implement a call to the system application "RDREC" in the IO controller and read the data record with the index 16#F880 from the I-device. The IO controller can now process the information about the assets and the centrally plugged modules of the I-device. Entry ID: 109748894, V1.0, 05/2018 17

Siemens AG 2018 All rights reserved 2 Engineering 2.5 Error handling Error in the IO controller If the I-device makes the asset management record available to an IO controller, the I-device checks the asset management record for errors in advance. If the I- device detects a discrepancy in the parameterization, you will receive the error code 0xDE80AA00 at the system application "RDREC". In this case, check whether you have parameterized the tags of the Management Block according to the specifications. Please also note the information in the description of the tags (see Section 3.1.2). Error in the function block "Management" If an error occurs in the program, the current status of the state machines and the cause of the error are written to the output parameters "statusid" and "status". At the output "statusid", the number of the state in which the error occurred is output. The states are numbered and have the following meaning.

It checks the IN_OUT parameters for correctness. This includes the following queries: Is the referenced tag an array or a NULL pointer? Is the data type of the referenced array tag of the type "typemanagamentonlysw", "typemanagamentonlyhw" or "typemanagamentfullinformation"? 2. The block determines the number of elements of the transferred array tags and thus calculates the number of bytes that all transferred asset management blocks need. 3. With the system application "Get_IM_Data" it reads the I&M data from every centrally plugged module. The I&M data of the module converts the block into an asset management block of the "full information" format. 4. The block calculates the number of bytes required by the (converted) asset management blocks for the centrally plugged modules. 5. Using the "Serialize" system application, the block creates the data structure required for the data record in the byte array of the "ManagementRecord" data block. 6. The block then uses the "Serialize" and "Move_BLK_VARIANT" system applications to copy the asset management blocks to the byte array of the "ManagementRecord" data block. 7. When all data has been copied and the data record is complete, the block releases the system application "PRVREC". The system application "PRVREC" makes the data record available to the higher-level IO controller. The IO controller uses the system application "RDREC" to read and receive the data record with the index 16#F880. Entry ID: 109748894, V1.0, 05/2018 25
