Chapter 1 Introduction RFID Defined RFID (Radio Frequency Identification) is a method to communicate information from one point to another point by the use of electromagnetic waves (radio waves). RFID has unique characteristics that make it attractive for use in industrial systems. For example, you have a shipping carton that must be loaded with various goods to meet the specific purchase order of a customer. You can attach a tag to the carton.
PAGE 12
Chapter 1 Introduction position modulation. The position of one pulse relative to a known reference point codes the value of a nibble or byte of data. This process allows the card to draw the maximum energy from the field almost continuously. Tags, which have no power source, can be energized at ranges of up to 1 m (3.3 ft) from a coupler that can only transmit power within the limits that international radio frequency (RF) regulations permit.

Chapter 2 RFID Components The numbering of the 64 bits is done according to ISO/IEC 15693-3; numbering starts with the least significant bit (LSB) 1 and ends with the most significant bit (MSB) 64. This way is in contrast to the general used bit numbering within a byte (starts with LSB 0). Byte 5 (bit 41…48) is the tag type. Byte 6 (bit 49…56) is the manufacturer code, which coincides with the number of bytes/block. Table 5 shows the structure of our RFID tags.
PAGE 20
Chapter 2 RFID Components Data Storage Format Identifier (DSFID) The DSFID indicates how data is structured in the tag memory. The respective commands can program and lock it. It is coded on 1 byte. It allows for instant knowledge on the logical organization of the data. Electronic Article Surveillance (EAS) EAS is a technology that is typically used to help prevent shoplifting in retail establishments. An EAS detection system detects active tags and sets off an alarm.
PAGE 21
Chapter 2 RFID Components EAS: e = 1 (EAS enabled) e = 0 (EAS disabled) IMPORTANT Only change the EAS Configuration in a secure environment. The label must not be moved out of the communication field of the antenna during writing. We recommend putting the label close to the antenna and not to remove it during the operation.

Chapter 4 EtherNet/IP Addressing Star Topology The star topology consists of a number of devices that connect to the central switch. When this topology is used, only one Ethernet connection can be made to the Bulletin 56RF interface block – this connection is made to the Link 1 connector. The Link 2 connection must remain unused.

Chapter 4 EtherNet/IP Addressing Figure 10 - Linear Topology RFID Interface Block Device Level Ring (DLR) Topology RFID Transceivers RFID Interface Block RFID Transceivers A DLR network is a single-fault tolerant ring network that is intended for the interconnection of automation devices. DLR topology is advantageous as it can tolerate a break in the network. If a break is detected, the signals are sent out in both directions. When this topology is used, both Ethernet connections are used.
PAGE 35
Chapter 4 EtherNet/IP Addressing Figure 11 - DLR Topology RFID Interface Block RFID Transceivers Setting the Network Address RFID Transceivers RFID Interface Block Before using the 56RF interface block in an EtherNet/IP™ network, configure it with an IP address, subnet mask, and optional Gateway address. This chapter describes these configuration requirements and the procedures for providing them. The address can be set in one of three ways: • Use the Network Address switches.
PAGE 36
Chapter 4 EtherNet/IP Addressing Figure 12 - Address Setting Example The subnet mask of the interface block is automatically set to 255.255.255.0 and the gateway address is set to 0.0.0.0. When the interface block uses the network address set on the switches, the interface block does not have an assigned host name or use a Domain Name Server (DNS). Advanced IP Addresses 34 Step 1…Step 6 show how to change the IP address from the fundamental 192.168.1.xxx to an advanced address.
PAGE 37
Chapter 4 EtherNet/IP Addressing b. When power is restored, the interface block repeatedly broadcasts its MAC ID and requests an IP address. The BOOTP-DHCP server displays the MAC ID in the Request History panel. c. Double-click one of the Ethernet addresses (MAC) of the device. The New Entry dialog appears, which shows the Ethernet address (MAC) of the device. d. Type in the IP address, host name, and description and click OK. The host name and description are optional fields; they can be left blank.
PAGE 38
Chapter 4 EtherNet/IP Addressing 5. Change the Network Adapter to 192.168.2.1. a. Open the network connections of the host computer. b. Highlight the Internet Protocol (TCP/IP) connection. c. Click Properties. In the IP address field, set the IP address to 192.168.2.1. Click OK. d. Click Close to close the Local Area Connection window (this window must be closed to apply the new address). 6. Disable DHCP. a. Set the rotary switches to 0 0 0. b.
PAGE 39
Chapter 4 EtherNet/IP Addressing f. From a DoS prompt, you can ping the new address. The response must be four packets sent, four packets received, and zero lost. Change IP Address from One Advanced Address to Another Advanced Address The easiest way to change the IP address from one non-simple address to another non-simple address is to use RSLinx. In this case, the three network switches on the 56RF interface block are set to 999, and the address has been previously set using the BootP/DHCP server.
PAGE 40
Chapter 4 EtherNet/IP Addressing a. Click Yes to confirm the change. b. To close the configuration window, click OK. RSLinx places an X over the RFID adapter because it can no longer communicate with it. c. Use the same steps to change the IP address of the other devices on the network. Change the Network adapter address to 192.168.3.1. d. Close and reopen the RSWho window. The older addresses are not available and the new addresses (192.168.3.115 and 192.168.3.214) appear.
PAGE 41
Chapter 4 EtherNet/IP Addressing In the following example, power was cycled to the 56RF interface block at 7:45:16, 7:47:47, 7:49:06, and again at 10:56:00. Each time power was applied, the 56RF interface block notified the BootP/DHCP server of its IP address, which indicates that DHCP has not been disabled. If DHCP is disabled, the 56RF interface block would show nothing. IP Address 888 Address 888 is used to reset the interface block to the factory defaults.

Chapter 5 Mechanical Installation Each transceiver generates a similar but unique RF field. Fastening Attach the transceiver to the flat plate with M5 screws. The tightening torque must be 1.5 N•m (13.3 lb•in) for the M5 screw. Spacing Between Transceivers The installation of multiple transceivers causes radio frequency interference and can result in tag communication difficulty. Keep a sufficient distance between the transceivers as shown in Figure 13.
PAGE 44
Chapter 5 Mechanical Installation Spacing Next to Metal Surfaces For the square transceiver, the communication distance drops significantly when the distance between the transceiver and any surrounding metal is 30 mm (1.2 in.) or less. For the rectangular transceiver, the communication distance drops significantly when the distance between the transceiver and any surrounding metal is 50 mm (2 in.) or less.

Chapter 9 RSLogix 5000 Code Examples This chapter contains examples of routines that run in the RSLogix 5000® program. The examples are written for an RF transceiver that is connected to the “0” connector on the RF interface block. A momentary switch is connected to the Digital Input connector. The switch is used to enable the routine to allow you to repeat the routine easily.
PAGE 66
Chapter 9 RSLogix 5000 Code Examples Rung 0 Rung 0 initiates the routine. A sensor or momentary switch, which is connected to the input connection of the RFID interface block, senses that an object (with an RFID tag attached) is approaching and enables the execution of the read routine. The sensor is the Examine If Closed (XIC) bit labeled _RFID_1:I:Pt00Data. When the sensor detects the object, the instruction latches ON. Rung 1 Rung 1 initializes the output image table in preparation for command.
PAGE 67
Chapter 9 RSLogix 5000 Code Examples RFID_1:I:Channel[0].Busy – When the command begins execution, the Busy bit goes HI. This contact closes and the rung is executed. InProgress – When command begins execution, an In-Progress bit is latched ON. Start – This contact is opened, as the command has transitioned from start to busy. Rung 4 Rung 4 confirms the completion of the command, as the interface block moves a value into the input channel command location.

Chapter 9 RSLogix 5000 Code Examples Example Results To demonstrate the results, the Read Byte command was executed on an RFID tag. The data in this tag was a simple list of numbers starting from 1. The counter is 31. The Clear Multiple Byte command is executed successfully as the ChError = 0 and all data bytes are zero. The counter increments to 32. The tag is read again (command = 4) to confirm the clearing. Data bytes 2...4 are successfully set to 0.
PAGE 69
Chapter 9 Get Multiple Block Security Status RSLogix 5000 Code Examples The Get Multiple Block Security Status command retrieves the security status of multiple blocks within a tag. It also displays the Universally Unique Identifier (UUID) of the RFID tag. Set the following values in the output image table: a. xx:O.Channel[0].Command = 45 b. xx:O.Channel[0].Address = the first block to read c. xx:O.Channel[0].Block = 0 d. xx:O.Channel[0].Data[0] = 0 e. xx:O.Channel[0].
PAGE 70
Chapter 9 RSLogix 5000 Code Examples Example Results The following example shows the security status for the first three blocks. Blocks 0 and 2 are locked. Block 1 is not locked.
PAGE 71
Chapter 9 RSLogix 5000 Code Examples The following information is displayed: • xx:I.Channel[0].Data[0…7] = UUID • xx:I.Channel[0].Data[8…9] = Security status of block x • xx:I.Channel[0].
PAGE 72
Chapter 9 RSLogix 5000 Code Examples Example Results The Info Flag contains data that is used to determine what parameters are passed back. The DSFID, AFI, and UUID follow. The tag being read was catalog number 56RRF-TG-30. This tag has 28 blocks. The maximum block number is 27, as the first block is 0. Each block has 4 bytes. The maximum byte number is 3, as the first byte is 0. The IC Ref is the last byte reported.
PAGE 73
Chapter 9 Get Version Information RSLogix 5000 Code Examples The Get Version Information command retrieves the firmware revision information from the transceiver. Set the following values in the output image table: a. xx:O.Channel[0].Command = 33 b. xx:O.Channel[0].Address = 0 c. xx:O.Channel[0].BlockSize = 0 d. xx:O.Channel[0].Data[0] = 0 e. xx:O.Channel[0].Length = 0 f. xx:O.Channel[0].Reset = 0 g. xx:O.Channel[0].Timeout = 0 h. xx:O.Channel[0].UIDLow = 0 i. xx:O.Channel[0].
PAGE 74
Chapter 9 RSLogix 5000 Code Examples Example Results The results are stored in Data [0…3]. In this example, the version is de20007 (version 2.07). Inventory The inventory command returns the UUID and DSFID information from the RFID tags in the field. This command can read up to a maximum of four tags. The more tags in the field, the more time the tags must be in the field to complete the inventory command.
PAGE 75
Chapter 9 RSLogix 5000 Code Examples Example Routine In the following example routine, the initialization in Rung 1 sets the address, length data, the Data[0] value that is used to clear the fields and sets the command value to 0. The BlockSize, Reset, Timeout, UIDLow, and UIDHi are set to 0 in the output image table. The example ladder diagram is initially set for Address =0, Length = 0 and Data[0] = 0.
PAGE 76
Chapter 9 RSLogix 5000 Code Examples Example Results In example 1, the Address = 0, Length = 0 and Data[0] = 0. Four RFID tags were in the RF field at the time the read command was executed. The controller tag values are shown in the following example. The data shows the number of tags in the RF field and the UUID for each tag. In example 2, the length was changed to 1, the Address = 0, Length = 1 and Data[0] = 0. Four RFID tags were in the RF field at the time the read command was executed.
PAGE 77
Chapter 9 RSLogix 5000 Code Examples In example 3, we get the tag information for only those tags that have a specific AFI. In this example, the AFI is 57. Address = 1, Length = 1 and Data[0] = 57. Two of the four RFID tags that were present in the RF field at the time the read command was executed had AFI set to 57. The controller tag values are shown in the following example. The data shows the number of tags in the RF field, the DSFID, and the UUID for each of these tags.
PAGE 78
Chapter 9 RSLogix 5000 Code Examples Example Routine In the following example routine, the initialization in Rung 1 sets the address, length, the Data[0, UIDLow and UIDHi values used to lock the AFI and sets the command value to 0. The BlockSize, Reset, and Timeout are set to 0 in the output image table. Example Results Figure 18 shows an example of results on the input image table. The Command is showing 42 and the ChError is showing 0. The input data bytes are all zero.
PAGE 79
Chapter 9 Lock Block RSLogix 5000 Code Examples The Lock Block command locks one block of user data, preventing future writing. The transceiver automatically determines the block size of the RFID tag. IMPORTANT Once the block is locked, the block cannot be unlocked. Set the following values in the output image table: a. xx:O.Channel[0].Command = 40 b. xx:O.Channel[0].Address = the number of the block to lock c. xx:O.Channel[0].BlockSize = 0 d. xx:O.Channel[0].Data[0] = 0 e. xx:O.Channel[0].
PAGE 80
Chapter 9 RSLogix 5000 Code Examples Example Results Figure 19 shows address 26, which is the second to last block of the catalog number 56RF-TG-30 tag. The command is 40. The UUID must be specified to lock any blocks. Figure 19 - Input Image Table After completion of the lock block command, the input image table shows that the command is 40 and the ChError is 0. Errors The ChErrorfield is 8 if you try to lock a block that is already locked.
PAGE 81
Chapter 9 Lock DSFID RSLogix 5000 Code Examples The Lock DSFID command locks the 1 byte of information for the Data Storage Format Identifier (DSFID) area of the tag, preventing it from being modified. IMPORTANT Once the DSFID byte is locked, it cannot be unlocked. Set the following values in the output image table: a. xx:O.Channel[0].Command = 44 b. xx:O.Channel[0].Address = 0 c. xx:O.Channel[0].Data[0] = 0 d. xx:O.Channel[0].Length = 0 e. xx:O.Channel[0].Reset = 0 f. xx:O.Channel[0].Timeout = 0 g.
PAGE 82
Chapter 9 RSLogix 5000 Code Examples Example Results When successful, the results shown in the input image table show ChError = 0 and the Command number =44. If you try to lock the DSFID on an RFID tag that is already locked, the ChError is equal to 8. Read Byte Command The Read Byte command reads a user-specified number of bytes from a tag, starting at a user-specified address. An Option Flag can be set to return the UUID of the tag.
PAGE 83
Chapter 9 RSLogix 5000 Code Examples In the following example routine, the initialization in Rung 1 sets the address, length, the Data[0]to the Option Flag, and sets the command value to 0. The BlockSize, Reset, Timeout, UIDLow, and UIDHi are set to 0 in the output image table. Example Results Figure 20 shows an example of results where the Option Flag was set to 1, which reads the UUID. The UUID is loaded into Data[0] through Data[7]. The user data (1, 2, 3, 4, 5, 6…) begins in Data[8].
PAGE 84
Chapter 9 RSLogix 5000 Code Examples In Figure 21, the command was repeated with the Starting Address set to 2 and the number of bytes set to 3. Figure 21 - Input Image Table - Repeated Command Multi-tag Block Read The Multi-tag Block Read command reads multiple blocks of user data from multiple tags in the RF field. The transceiver automatically determines the block size. All RFID tags in the field will have the same block size. This command can read up to four tags.
PAGE 85
Chapter 9 RSLogix 5000 Code Examples Example Results The input image data fields are populated with the number of tags, followed by the UUID and block data of each tag. In the following example, four catalog number 56RF-TG-30 RFID tags were read. These tags hold 4 bytes per block. Since two blocks (25 and 26) were read, a total of eight data fields are used to store the user data. The image only shows the information from two of the four RFID tags.
PAGE 86
Chapter 9 RSLogix 5000 Code Examples Read Multiple Blocks The Read Multiple Blocks command reads multiple blocks of user data from an RFID tag. Option Flags can be set to return just the data in the blocks or return the data and the security status for each block of data. The maximum number of blocks that can be read at one time is 10. • Option Flag 0 Returns multiple blocks of user data. Set xx:O.Channel[0].Data[0] = 0.
PAGE 87
Chapter 9 RSLogix 5000 Code Examples Example Results This first example uses Option Flag = 0; return only the data in the blocks. With a starting block number of 25 and two blocks to read, data from Blocks 25 and 26 are returned. The tag was a catalog number 56RF-TG-30, which has only 4 bytes per block. The data appears in the input channel Data[0…7]. This second example shows the results for Option Flag = 1; return the data and the security status.
PAGE 88
Chapter 9 RSLogix 5000 Code Examples The data for the second block appears in the input channel Data[6…9]. The security status appears in Data[10]. The value of 1 indicates that the block is locked. Read Single Block The Read Single Block command reads one block of user data from a tag. Option Flags can be set to return information the UUID and security status of the block. • Option Flag 0 Returns one block of user data. Set xx:O.Channel[0].Data[0] = 0.
PAGE 89
Chapter 9 RSLogix 5000 Code Examples Example Results • Option Flag 0 This first example uses Option Flag = 0; return only the data in the block. The block number is 26. The tag was a catalog number 56RF-TG-30, which has only 4 bytes per block. The data appears in the input channel Data[0…3]. • Option Flag 1 The second example demonstrates the results when Option Flag = 1. Data[0] shows the security status of the block. The 1 indicates that the block has been locked.

Chapter 9 RSLogix 5000 Code Examples Read Transceiver Settings The Read Transceiver Settings command retrieves the following information from the transceiver: • Device ID • Communication rate • Retry time • Gain Set the following values in the output image table: a. xx:O.Channel[0].Command = 31 b. xx:O.Channel[0].Address = 0 c. xx:O.Channel[0].BlockSize = 0 d. xx:O.Channel[0].Data[0] = 0 e. xx:O.Channel[0].Length = 0 f. xx:O.Channel[0].Reset = 0 g. xx:O.Channel[0].Timeout = 0 h. xx:O.Channel[0].
PAGE 91
Chapter 9 RSLogix 5000 Code Examples Example Results The following information is displayed: • xx:I.Channel[0].Data[0…1] = Device ID • xx:I.Channel[0].Data[2…5] = Communication rate • xx:I.Channel[0].Data[6…7] = Retry setting • xx:I.Channel[0].Data[8…9] = Gain Gain is 0…3, with 0 being the highest gain. Write AFI The Write AFI command writes 1 byte of information into the AFI. The AFI is used to group RFID tags by application.
PAGE 92
Chapter 9 RSLogix 5000 Code Examples Example Results Figure 22 shows an example of results on the input image table. The Command is showing 41 and theChError is showing 0. The data bytes are all zero. Confirmation that the AFI was written can be observed in the Get_System_Information_Routine. Figure 22 - Input Image Table Write Byte Command 90 The Write Byte command writes bytes of user data to a tag. You must specify the data, the start byte, and the number of bytes to write. a. xx:O.Channel[0].
PAGE 93
Chapter 9 RSLogix 5000 Code Examples Unless a UUID is specified, this command operates on the first tag in the field. Specify a UUID in xx:O.Channel[0].UIDLow and xx:O.Channel[0].UIDHi to perform the command on a specific tag. Example Routine In the following example routine, the initialization in Rung 1 sets the address, length, and Data[0] values used to read multiple blocks and sets the command value to 0. The BlockSize, Reset, Timeout, UIDLow, and UIDHi are set to 0 in the output image table.
PAGE 94
Chapter 9 RSLogix 5000 Code Examples After successful completion of the Write Byte command, the input image table shows the UUID of the tag. The Read_Byte_Routine can be used to read the data. The data is stored in the input channel data, starting at location 0. Write DSFID The Write DSFID (Data Storage Format Identifier) command writes 1 byte of information in the Data Storage Format Identifier (DSFID) of the RFID tag. Set the following values in the output image table: a. xx:O.Channel[0].
PAGE 95
Chapter 9 RSLogix 5000 Code Examples The example ladder diagram is initially set for Address =0, the Length = 0. Data[0] is set to the DSFID value. Example Results The command is executed successfully if the ChError = 0, the Command value = 43 and all Data bytes are 0. Use the Get System Information command or the Inventory command to read the DSFID.
PAGE 96
Chapter 9 RSLogix 5000 Code Examples Write Multiple Blocks The Write Multiple Blocks command writes to either one or two blocks of user data to a FRAM tag. This command only works on FRAM tags. Catalog number 56RF-TG-2KB is a FRAM tag. a. xx:O.Channel[0].Command = 11 b. xx:O.Channel[0].Address = starting block to write c. xx:O.Channel[0].BlockSize = number of bytes per block d. xx:O.Channel[0].Data[0…xxx] = data to write e. xx:O.Channel[0].Length =the number of blocks to write f. xx:O.Channel[0].
PAGE 97
Chapter 9 RSLogix 5000 Code Examples Example Results Figure 24 shows the output image table with the data that is written (a simple numeric sequence starting at 2). Two blocks of 8 bytes each is written to the tag. The data is written to address locations 3 and 4. Figure 24 - Output Image Table If the Write Multiple Blocks command is executed properly, the input table image results show ChError = 0, Command = 11 and Data[0-xxx] =0.
PAGE 98
Chapter 9 RSLogix 5000 Code Examples Use the Read Multiple Block command (=2) to read the data. Multi-tag Block Write The Multi-tag Block Write command writes one or more blocks of user data to multiple tags in the transceiver field. The maximum number of tags in the RF field is limited to four and all tags must have the same block size. Set the following values in the output image table: a. xx:O.Channel[0].Command = 12 b. xx:O.Channel[0].Address = starting address to write c. xx:O.Channel[0].
PAGE 99
Chapter 9 IMPORTANT RSLogix 5000 Code Examples The BlockSize field is used to specify the number of bytes/block of the tag. Valid values are: • 0 = 4 bytes/block • 4 = 4 bytes/block • 8 = 8 bytes/block Typically, ISO15693 tags have a block size of 4 bytes/block, and FRAM tags have a block size of 8 bytes/block. Example Routine In the following example, data is written to two blocks, starting with Block 3. The data is loaded into the output channel image table.
PAGE 100
Chapter 9 RSLogix 5000 Code Examples Example Results The input channel image table shows the number of RFID tags that were written and the UUID of each RFID tag. Use the Read Multi Tag Block command (=3) to read the blocks and confirm that the data was written.
