    Introduction This document describes the RFID Reader Interface for the SIMATIC handheld systems RF610M and RF310M and how this interface can be utilized. The document consists of two parts. The first part gives you an overview of how the RFID Reader Interface can be used and the second part contains a detailed reference description of the RFID Reader Interface.

    RFID Reader Interface User's Guide RFID Reader Interface Simatic Handheld devices enable end users to acquire tag data from any place without the limitations of a cable-bound system. It provides the hardware as well as a software application to use the features of the mobile reader. Figure 2-1 Software system structure on a SIMATIC Handheld device.
  • Page 10: How Do I Use The Reader Interface

    Moreover, in order to utilize the RFID features you will also need to reference the RFID Reader Interface assembly within your applications. This assembly is available on your handheld device. You can retrieve the file Siemens.Simatic.RfReaderApi.dll via ActiveSync from the handheld device (\Flash Disk\SIMATIC xxx\Support\RFID_AP\RFID_API.ZIP) and store it to reference the assembly.
  • Page 11: Creating The Application

    RFID Reader Interface User's Guide 2.2 How Do I Use the Reader Interface? 2.2.2 Creating the Application To start a new application for a handheld device, create a new project of type 'Visual C#\Smart Device\Windows CE 5.0\DeviceApplication' since handheld devices currently run under Windows CE 5.0.
  • Page 12: Starting The Rfid Reader

    To simplify development, first add a reference to the RFID Reader Interface assembly and a directive for the namespace Siemens.Simatic.RfReader which enables you to use 'intelli- sense' on the types provided by the RFID Reader Interface. Figure 2-4 Adding a reference to the reader interface: Go to where you filed the interface assembly which you retrieved from the handheld device.
  • Page 13 RFID Reader Interface User's Guide 2.2 How Do I Use the Reader Interface? Another look at our code shows that only four lines of code are needed to start up the reader service. The code for starting the RFID Reader Interface: private void menuReaderStart_Click(object sender, EventArgs e) // We want to create and start an instance of the RFID // reader interface for a handheld device with a default name.
  • Page 14 RFID Reader Interface User's Guide 2.2 How Do I Use the Reader Interface? A last issue we have to consider is that the RFID reader service needs time to initialize his internal states. The good news is that after initialization the reader service will use its Alarm event mechanism to notify clients when it is ready to start work.
  • Page 15: Compile And Run

    RFID Reader Interface User's Guide 2.2 How Do I Use the Reader Interface? 2.2.4 Compile and Run Even if tags cannot be read yet, you can create an application to prove that it can at least start up and shut down.

  • Page 18: I Want To See Tags

    RFID Reader Interface User's Guide 2.2 How Do I Use the Reader Interface? 2.2.5 I Want To See Tags… You are able to start and stop the RFID reader service and would now like to see tags. Another look at the RfReaderApi interface reveals a member called GetTagIDs. Checking the return value’s type indicates that you will receive an array of strings containing the read tag IDs.
  • Page 19: Know More About The Tags

    RFID Reader Interface User's Guide 2.2 How Do I Use the Reader Interface? 2.2.6 Know More about the Tags … You can learn more about tags in the same way that you can access additional data on tags or write data to tags. Some additional data must be specified.

    RFID Reader Interface User's Guide 2.2 How Do I Use the Reader Interface? 2.2.7 Change the Tags' Data When the data on a tag must be changed, the same restriction applies on EPC Gen2 tags as with obtaining additional data. The EPC Gen2 tag that you want to change must be specified by supplying its ID.

    Summary Using the RFID Reader Interface is easy if you keep the few important points below in mind. ● Be sure to reference the Siemens.Simatic.RfReaderApi.dll assembly, use its namespace and place the assembly beneath your application on the target device.

So he takes his RF610M device with him, walks up to the package in aisle three and scans the package again just for monitoring purposes.
  • Page 24: Entering The System

    RFID Reader Interface User's Guide 2.3 Extending the Reach 2.3.2 Entering the system How do we achieve to be part of a larger system with an RF610M? The good news is that starting with RF-MANAGER 2008 the RF610M can be configured within a project as just another reader.
  • Page 25: Wake Me Up Before You Go

    RFID Reader Interface User's Guide 2.3 Extending the Reach 2.3.3 Wake me up before you go… So far, so good – we will wait until the configuration has been finished. But how do we know it has finished? Luckily the RFID reader interface provides a notification mechanism which enables us as a client of the API to know what is going on.
  • Page 26 RFID Reader Interface User's Guide 2.3 Extending the Reach Nevertheless, this means, we can always rely on getting an event during startup – no matter what. Great, we now know when we are started. Normally, you start an underlying reader service during startup of your client via StartReader() and you stop it again during shutdown of your client with the StopReader() function of the RFID reader interface causing the reader service to terminate as well.
  • Page 27 RFID Reader Interface User's Guide 2.3 Extending the Reach On a connected host PC we start a RF-MANAGER runtime with an RF610M device configured as follows. Notice that the reader type and the application mode have to be set accordingly. Figure 2-9 RF610M Properties As a side node, please bear in mind to set the network address for your runtime under...

  • Page 33 RFID Reader Interface User's Guide 2.3 Extending the Reach Most interesting here is the last constant which ensures that all available data sources are subscribed. Most often ‘NC_ALL’ is the safest option. Running the application again now gives us what we wanted. Whenever we are not subscribed, toggling the trigger will show tag events only at the RF-MANAGER runtime.

  • Page 37 RFID Reader Interface User's Guide 2.3 Extending the Reach Initially, all of the special keys produce the same keycode 0xEF or 239 decimal. So, whenever such a code arrives with a key down event, we set our trigger to active. And if the key is released again, we reset the trigger.
