Introduction

Chapter 1

What is RFID?

RFID stands for Radio Frequency Identification. It is a method for communicating information from one point to another point by the use of electromagnetic waves (i.e., radio waves). It 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 a customer’s specific purchase order. You can attach a tag to the carton. Prior to attaching the tag , you fill the tag with the specific items that the customer wants. Then, as the carton moves to the filling stations, each station places the required objects, only if needed, into the carton. If the tag does not require something, the station is skipped.

Each filling station has an RFID transceiver. The transceiver reads and writes to the tag. When the tag approaches the RFID transceiver, the transceiver reads the contents of the tag. Based on the information received, the packaging process adds items (or skips this step) and then writes to the tag that the item(s) was added. The carton moves to the next filling station.

This is a common use of RFID technology. What makes the Bulletin 56RF product line unique is its conformance to the open international standards: ISO15693 and ISO18000-3 M1.

International Standard Compliance

ISO/IEC 15693 is an ISO standard for what are called vicinity tags. The tags, commonly referred to as ICODE tags, can be read from a greater distance than proximity tags and closed couple tags. ISO/IEC 15693 systems operate at the

13.56 MHz frequency, and offer maximum read distance of 3.3…4.9 ft (1…1.5m), depending on the transceiver. Library applications with very large antennas are capable of these distances. Most industrial applications are less than 8 in. (20.3cm) for a read/write range.

The ICODE compatible tags permit users to use lower cost tags than proprietary systems currently provide. Users have the ability to use tag configuration options from multiple vendors.

ISO/IEC 15693 forms part of a series of International Standards that specify non-contact tags. The tags can be attached to objects, like cartons, bags, and valuable items, which can then be tracked while in the vicinity of a reading device. ISO/IEC 15693-2:2006 defines the power and communications interface between the vicinity card and the reading device. Other parts of ISO/IEC 15693 define the physical dimensions of the card and the commands interpreted by the card and reader.

Chapter 1 Introduction

Power is coupled to the tag by an AC field produced in the transceiver. The powering field has a frequency of 13.56 MHz and is one of the industrial, scientific and medical (ISM) frequencies available for worldwide use. When sufficient power is received by the tag, it is able to respond to commands sent from the coupler. The coupler sends commands to the card by modulating the powering field and by using a modulation system known as pulse position modulation, whereby the position of a single pulse relative to a known reference point codes the value of a nibble or byte of data. This 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 3.3 ft (1 m) from a coupler that can only transmit power within the limits permitted by international radio frequency (RF) regulations.

A tag only responds when it receives a valid command that selects a single tag from a possible collection of cards within range of the coupler. This process of collision detection and selection, also known as anti-collision, is made possible by detecting the unique identification number encoded into every tag. Anticollision, and the commands used, are defined in ISO/IEC 15693-3. The tag responds to the transceiver by drawing more or less power from the field and generates one or two sub-carriers of around 450 kHz. These are switched on and off to provide special-encoded data that are then detected by the transceiver.

Backward Compatibility

The Bulletin 56RF RFID system will be offered initially on EtherNet/IP and is backward compatible with the previous offering of Bul. 56RF ICODE products. The transceivers and interface blocks are a matched pair so they cannot be interchanged. However, the tags can be interchanged with either system if they are ICODE tags. Both systems can read and write these tags seamlessly.

System Setup

The figure below shows a simple RFID system. This user manual describes the setup, installation, and programming required to get this system running.

Figure 1 - RFID System

Tags are attached to objects that need to be tracked. The tags hold important information about the object. An RF transceiver reads and/or writes information to the tags when the tag moves within the transmission envelope of the transceiver (dotted ellipse). The physical size of the transceiver is directly related to the size of the transmission field. The larger the transceiver, the longer and wider the antenna field is. Please see transceiver instruction sheets for antenna field sizes.

The transceivers are connected to a special RFID EIP interface block. The distribution block has an EtherNet connection to an EtherNet switch. An L35E CompactLogix controller and a personal computer also have EtherNet connections to the EtherNet switch.

Tag Memory Structure

Universally Unique Identifier (UUID)

Each tag has a different 64-bit hexadecimal UUID that is programmed during the production process according to ISO/IEC15693-3 and cannot be changed afterwards.

The numbering of the 64 bits is done according to ISO/IEC 15693-3 starting with the least significant bit (LSB) 1 and ending with the most significant bit (MSB) 64. This is in contrast to the general used bit numbering within a byte (starting 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.

The table below shows the RFID tags offered by Rockwell Automation and their structure.

Application Family Identifier (AFI)

The AFI represents the type of application targeted. AFI is coded on one byte, which constitutes two nibbles of 4 bits each. The most significant nibble of AFI is used to code one specific or all application families, as defined in the table below. The least significant nibble of AFI is used to code one specific or all application sub-families. Sub-family codes different from 0 are proprietary.

Data Storage Format Identifier (DSFID)

The DSFID indicates how data is structured in the tag memory. It may be programmed and locked by the respective commands. It is coded on one byte. It allows for instant knowledge on the logical organization of the data.

Electronic Article Surveillance (EAS)

EAS is a technology typically used to prevent shoplifting in retail establishments. An EAS detection system will detect active tags and set off an alarm.

EAS status is 1 bit data (LSB side), which is stored in the system area of a tag. The initial value is “1”. EAS bit “1” means goods-monitoring status, and EAS bit “0” means that goods-monitoring status is cleared.

Smart Label Integrated Circuit (SLI)

SLI tags use an EEPROM (electrically erasable programmable read only memory) to store data. The 1024 bit EEPROM memory is divided into 32blocks. Each block consists of 4 bytes (1block= 32 bits). Bit 0 in each byte represents the least significant bit (LSB) and bit 7 the most significant bit (MSB), respectively.

Changing of the EAS Configuration must be done in secure environment. The label must not be moved out of the communication field of the antenna during writing. We recommend to put the label close to the antenna and not to remove it during the operation.

Application Family Identifier

The ICODE system offers the feature to use an Application Family Identifier (AFI) at the inventory command and the two custom commands inventory read and fast inventory read (this allows for example the creation of label families).

This 8-bit value is located at Byte 2 in Block -2 as shown in the following figure and is only evaluated if the AFI flag is set in the reader command.

Write Access Conditions

The Write Access Condition bits in block -1 determine the write access conditions for each of the 28 user blocks and the special data block. These bits can be set only to 1 with a lock command (and never be changed back to 0), i.e. already write protected blocks can never be written to from this moment on.

In block -2 each byte can be individually locked.

Smart Label IC – Secure (SLI-S)

The 2048 bit EEPROM memory is divided into 64 blocks. A block is the smallest access unit. Each block consists of 4 bytes (1block=32 bits). Four blocks are summed up to one page for password protection. Bit 0 in each byte represents the least significant bit (LSB) and bit 7 the most significant bit (MSB), respectively.

The memory is divided into two parts:

• Configuration Area: This memory area stores all required information, such as UID, EPC data, write protection, access control information, passwords, etc. Direct access to this memory area is not possible.

•User Memory: This memory area stores user data. Direct read/write access to this part of the memory is possible depending on the related security and write protection conditions.

Ferroelectric Random Access Memory (FRAM)

FRAM is a non-volatile memory that uses ferroelectric film as a capacitor for storing data. FRAM offers high speed access, high endurance in write mode, low power consumption, non-volatility, and excellent tamper resistance. The FRAM tags have 2000 bytes for use as user area and 48 bytes for use as system area.

The FRAM tag memory areas consist of a total of 256 blocks (250 blocks of user area and 6 blocks of system area). Each block can store 64 bits (8 bytes) of data.

The block is the unit used for the writing and reading of FRAM data. The memory configuration of FRAM is shown below.

EAS bit is a single bit, and it is used for setting EAS status. It is possible to read/ write data of two blocks at one time in the user area (if Read Multiple Blocks Unlimited command is used, up to 256 blocks can be accessed at one time) .

The RFID ICODE handheld interface provides a portable solution for reading/ writing values to the tag data area. The handheld interface is a touch-screen operated computer with an attached RFID antenna and software that allows reading, writing, and saving tag RFID tag data. Each handheld interface comes with multiple connectivity methods, such as wireless, Bluetooth, and USB, which allow tag data to be transferred to/from a computer. The RFID ICODE handheld interface is IP65 rated for harsh industrial and outdoor environments. It is the ideal accessory for system setup, field service, fleet management, time and attendance, and any other application where transceiver mobility is required.

For more information on the RFID ICODE handheld interface, refer to Publication 57RF-UM001.

IMPORTANT

Auxiliary Power Connection

Attach a micro-style 4-pin female to the micro-style 4-pin male receptacle as shown below. The female side is used to daisy chain the power to another device. The power connection is limited to 4 A. When the daisy chain approach is used, the maximum number of interface blocks that can be connected is determined by the total power consumed by each block.

Power must be connected to the male connector first. Do not connect power to the female connector and leave the male connector exposed. The pins in the male connector will have 24V DC potential for short circuit.

The pin connections for the aux power connectors are shown below:

The power for the output port is separate from the power to the remaining portions of the interface block. This allows the output device to be turned off, while maintaining power to the transceivers, the input port, and the EtherNet/IP connection. When the output is connected to the safety related portion of the machine control system, an actuator can be turned off, while diagnostic information is still available to the machine control system.

Power Connection Options

Each interface block is limited to 4 A total consumption.

Example 1: Daisy Chain the Power Connections

This example allows for a simple and easy way to distribute power to the RFID system. This approach is preferred when the total current of the RFID system is less than 4 A.

Figure 7 - Power Option 1

Example 2: System Needs More Than 4 A

If multiple blocks are required on a machine and the current consumption exceeds 4 A, then a combination of mini-style and micro-style connections can be used to distribute the power. In the example below, mini-style cordsets, patchcords and tees are used to set up the power. A mini-to-micro style patchcord connects each Bul. 56RF interface block with the tee. In this example, the power supply is a Cat. No. 1606-XLDNET8, which can supply up to 8 A to the RFID system.

Linear Topology

The linear topology uses the embedded switching capability to form a daisychain style network that has a beginning and an end. Linear topology simplifies installation and reduces wiring and installation costs, but a break in the network disconnects all devices downstream from the break. When this topology is used, both EtherNet connections are used. The network connection to Link 1 or Link 2 does not matter.

Device Level Ring (DLR) Topology

A DLR network is a single-fault tolerant ring network 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. The network connection to Link 1 or Link 2 does not matter.

Rockwell Automation recommends that you use no more than 50 nodes on a single DLR, or linear, network. If your application requires more than 50 nodes, we recommend that you segment the nodes into separate, but linked, DLR networks.

With smaller networks:

• there is better management of traffic on the network.

• the networks are easier to maintain.

• there is a lower likelihood of multiple faults.

Additionally, on a DLR network with more than 50 nodes, network recovery times from faults are higher. The maximum cable length between devices cannot exceed 100 m (328 ft).

For more information on setting up and configuring a DLR network, please refer to ENET-AP005.

Chapter 4 EtherNet/IP Addressing

Setting the Network Address

Fundamental IP Addresses:

192.168.1.xxx

Before using the Bul. 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.

• Use the Rockwell BootP/DHCP utility (version 2.3 or greater), which

ships with RSLogix™ 5000.

• Use RSLinx® software.

IP network addresses have a format of xxx.xxx.xxx.xxx. The user must know what values are being used for the network. If your network has the fundamental

192.168.1.xxx scheme, then you can simply use the three network address switches. If your network is something other than 192.168.1.xxx, you must use advanced tools, such as the BootP/DHCPserver, to assign an IP address. After the address is set, you can use RSLinx to change the address.

If your network scheme is 192.168.1.xxx, then you can adjust the network address switches to set the IP address. Remove the covers of the three network address screws. Use a small blade screwdriver to rotate the switches. Line up the small notch on the switch with the number setting you wish to use. Valid settings range from 001…254

When the switches are set to a valid number, the IP address of the interface block is 192.168.1.xxx (where xxx represents the number set on the switches). Cycle the power and the valid setting becomes effective immediately.

The example below shows an address setting of 192.168.1.123.

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 a host name assigned to it or use a Domain Name Server (DNS).

38 Rockwell Automation Publication 56RF-UM001A-EN-P - October 2011

Page 39

EtherNet/IP Addressing Chapter 4

Advanced IP Addresses

The following steps show how to change the IP address from the fundamental

192.168.1.xxx to an advanced address. This assumes the Bul. 56RF interface block was already set up with an IP address using the network address switches. The examples below show the change process using specific addresses. The user is not limited to these addresses; the user can select any address that meets their needs. In the example below, we change from 192.168.1.115 to 192.168.2.115.

1. Set address switches to 888 and cycle the power.

On the Bul. 56RF interface block, the address switches had previously been to 115. Set the address switch settings to 888. Cycle the power and wait until the MOD indicator is blinking red. The MOD indicator blinks red once, green once, then solid red for a short while, then blinks green once, and finally blinks red continuously (about once each second). This takes about 10 seconds after power is restored. The interface block is reset to its factory setting.

2. Set the address switches to 999 and cycle the power.

On the Bul. 56RF interface block, set the address switch settings to 999. Cycle the power and wait until the MOD indicator is solid green. The MOD indicator blinks red once, green once, solid red for a short while and finally turns solid green. This takes about 10 seconds after power is restored. The interface block IP address is reset.

3. Use BootP/DHCP Server to set new address

Use the Rockwell BootP/DHCP Server utility to assign a valid address to the interface block. From the Start button, select Programs > RockwellSoftware > BOOTP-DHCP Server > BOOTP-DHCP Server.

When power is restored, the interface block repeatedly broadcasts its MACID and requests an IP address. The BOOTP-DHCP server displays the MACID in the Request History panel.

Double-click on one of the EtherNet Address (MAC) of the device. The New Entry dialog appears showing the EtherNet Address (MAC) of the device.

Type in the IP Address, Hostname and Description and click OK. The Hostname and Description are optional fields; they can be left blank.

The device is added to the Relation List, displaying the EtherNet Address (MAC) and corresponding IP Address, Hostname, and Description.

When the address is assigned to the Bul. 56RF interface block, 1) the Status message is updated, and 2) the IP address appears in the Request History window.

40 Rockwell Automation Publication 56RF-UM001A-EN-P - October 2011

Wait for the Status message to show “Sent 192.168.2.115 to EtherNet address 00:00:BC:E5:D0:1D.” This may take a few seconds to 30 seconds.

4. At this point, the IP addresses of other devices should be changed.

Page 41

EtherNet/IP Addressing Chapter 4

5. Change the Network Adaptor to 192.168.2.1.

Open the network connections of the host computer. Highlight the Internet Protocol (TCP/IP) connection. Click Prop erties. In the IP Address field, set the IP Address to 192.168.2.1. Click OK. Click Close to close the Local Area Connection window (this window must be closed to apply the new address).

6. Disable DHCP.

Click on (only once) the interface block in the Relation List to highlight it. Then click Disable BOOTP/DHCP. This instructs the Bul. 56RF interface block to retain the IP Address at the next power cycle.

Wait for the Status message to show that the command was successfully sent. If not, repeat this step.

Rockwell Automation Publication 56RF-UM001A-EN-P - October 2011 41

Chapter 4 EtherNet/IP Addressing

Click File > Save As to save the relationship, if desired.

Cycle the power to the Bul. 56RF interface block. You should no longer see the Bul. 56RF interface block appear in the Request History panel.

From a DOS prompt, you can ping the new address. The response should be 4 packets sent, 4 packets received and 0 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 Bul. 56RF interface block are set to 999, and the address has been previously set using the BootP/DHCP server. The example below shows how to change the IP address from 192.168.2.115 to 192.168.3.115.

Open RSLinx.

1. Click on the RS-Who icon.

2. Expand the EtherNet connection.

42 Rockwell Automation Publication 56RF-UM001A-EN-P - October 2011

3. Right click on the RFID Adaptor.

4. Click Module Configuration.

Page 43

EtherNet/IP Addressing Chapter 4

The Configuration window appears.

1. Click on the Port Configuration tab.

2. Set the Network Configuration Type to Static (if not already done).

3. Change the IP Address to the new address. In this example, the address will

be changed form 192.168.2.115 to 192.168.3.115.

Click Ye s to confirm the change.

Click OK to close the configuration window.

RSLinx places an X over the RFID adaptor because it can no longer communicate with it.

Use the same steps to change the IP address of the other devices on the network.

Change the Network adaptor address to 192.168.3.1.

Rockwell Automation Publication 56RF-UM001A-EN-P - October 2011 43

Chapter 4 EtherNet/IP Addressing

Close and re-open the RSWho window. The older addresses are not available and the new addresses (192.168.3.115 and 192.168.3.214) appear.

Note: If DHCP is not disabled, the Bul. 56RF interface block will show two requests in the DHCP Server at each power up.

In the picture below, power was cycled to the Bul. 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 Bul. 56RF interface block notified the BootP/DHCP server of its IP Address. This indicates that DHCP has not been disabled. If DHCP is disabled, the Bul. 56RF interface block would show nothing.

IP Address 888

44 Rockwell Automation Publication 56RF-UM001A-EN-P - October 2011

Address 888 is used to reset the interface block to the factory defaults. Rotate the address switches to 888 and cycle the power. The interface block clears out the current assigned IP Address.

The MOD indicator blinks the following pattern: blinks red once, green once, then solid red, then blinks green once, and final blinks continuous red about once each second. The reset process takes about 10 seconds.

For the square transceiver, the communication distance will drop 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 will drop significantly when the distance between the transceiver and any surrounding metal is 50mm (2 in.) or less.

Figure 13 - Tranceiver Spacing with Metal Surfaces

Transceiver Field Maps

The transceiver has a three-dimensional RF field emanating from its sensing surface. The field consists of a main center lobe and a secondary side lobe.

The RF tags must enter the RF field once, stay long enough to complete the read and write cycles, and then to leave the field smoothly and efficiently.

Ideally, the RFID tag should pass through the widest section of the main lobe. This maximizes the time the transceiver has for reading and writing. Avoid the top of the field, and avoid the side lobes.

The preferred direction of travel is for the tag to pass across the RFID sensor surface. The tag can also approach the sensor surface directly and then move away directly backwards or to the side.

•CRN – The Configuration Revision Number is used internally with RSLogix for configuration information. The user does not need to use this tag.

• Pt00FaultMode – The Pt00FaultMode is used in conjunction with FaultValue to configure the state of output 0 when a communications fault occurs. A value of 0 means that, in the case of a communications fault, the value in FaultValue will be used (Off or On). A value of 1 means that the last state will be held. By default this value is 0.

• Pt00FaultValue – The Pt00FaultValue is used in conjunction with FaultMode to configure the state of output 0 when a communications fault occurs. A value of 0 is Off, and a value of 1 is On. By default the value is 0.

• Pt00FilterOffOn – The Pt00FilterOffOn is used to determine the Off to On delay time for input point 0 before the interface considers the input point on or True. A value of 0 indicates there is no delay from an off condition to an on condition; the only delay would be a hardware delay. A value >0 would delay the input turning on by the configured value in milliseconds. By default this value is 0.

• Pt00FilterOnOff – The Pt00FilterOnOff is used to determine the On to Off delay time for input point 0 before the interface considers the input point off or False. A value of 0 indicates there is no delay from an on to off condition; the only delay would be a hardware delay. A value >0 would delay the input turning off by the configured value in milliseconds. By default this value is 0.

• Pt00NoLoadEn – The Pt00NoLoadEn is used to enable or disable No Load diagnostic detection for output 0. A value of 1 means that No Load diagnostic detection is enabled. A value of 0 means that No Load diagnostic detection is disabled. By default this value is 0.

• Pt00OpenWireEn – The Pt00OpenWireEn is used to enable or disable the open wire detection for input point 0. A value of 1 means that open wire detection is enabled. A value of 0 means that open wire detection is disabled. By default this value is 1.

• Reset – The channel reset bit is used to command an RFID channel reset. A value of 0 indicates the channel is not being commanded to reset, a value of 1 indicates a request to reset the channel.

•Timeout – This value determines how long the interface will wait for a command response from the transceiver before indicating a message time out. The default value is 0, which sets the timeout at 750 ms. The user can enter a timeout value in milliseconds, keeping in mind that a low timeout value can cause command failures by timing out before the command would otherwise have successfully completed.

•UIDHi – The channel UID word is an 8-byte value that will contain the UUID information for specific commands that will allow the command to be targeted to a specific tag in the field. Under normal circumstances this value will be 0, which tells the RFID interface to perform an action regardless of what tag it is. Any value other than 0 will attempt to direct the command to that specific tag. The UIDHi value contains bytes 0…1 and 6…7 of the UID.

•UIDLow – The UIDLow value contains bytes 2-5 of the UID.

Main Routine

Chapter 9

RSLogix 5000 Code Examples

This chapter contains examples of routines that will run in RSLogix 5000.

The examples are written for an RF transceiver 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 the user to repeat the routine easily.

In the examples, the RFID block is identified as “_RFID1”

A partial listing of the Main Routine is shown below. The Main Routine sets the run bit. In program mode, the run bit is 0; and 1 for run mode. The remaining blocks jump to the various subroutines to execute the commands. In Rung 1, the momentary switch turns on Digital Output 0, which turns on an LED to confirm that the user has pressed the momentary switch.

Chapter 9 RSLogix 5000 Code Examples

IMPORTANT

Example Command Routines

- Overview

Many of the example routines (not the Main Routine) use the same ladder logic. The ladder logic is explained below.

Rung 0

Rung 0 initiates the routine. A sensor or momentary switch, 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 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. Execution begins when the transceiver is not already busy reading a tag and a tag is present in the RF field.

This Examine If Closed (XIC) instruction is latched ON by the sensor in Rung0.

RFID_1:I:Channel[0]Busy – This Examine If Open (XIO) instruction prevents the rung from executing when the transceiver is busy executing a command.

RFID_1:I:Channel[0].TagPresent – This XIC instruction closes when a tag is present in the RF field of the transceiver connected to Channel[0].

MOV variable to RFID_1:O:Channel[0]:variable – Moves data from a Controller tag to the output image table variable.

MOV 0 to RFID_1:0:Channel[0].Command – This initializes the output command to 0.

The transceiver executes a command when the command value changes. When repeating a command, set the command value to 0 first and then re-set it to the same desired value.

Start – Latches a tag that indicates the function has started.

Unlatch – This unlatches (turns OFF) the instruction from Rung 0 and readies the routine for the next RFID tag.

68 Rockwell Automation Publication 56RF-UM001A-EN-P - October 2011

Page 69

RSLogix 5000 Code Examples Chapter 9

Rung 2

Start – With the output channel properly initialized, the Start bit enables the rung to begin execution.

EQU RFID_1:I:Command[0].Command =0 – When an output command is updated, the interface block returns that command back to the input command. If the input command is zero (it was set in Rung 1), then the EQU output goes HI and enables the subsequent MOV command.

MOV x to RFID_1:O:Command[0].Command – Moving a non-zero value into the output command byte instructs the RFID block to execute the command.

Rung 3

Rung 3 ensures that another command is not initiated while a command is busy.

Start – The Start bit enables the rung to begin execution.

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.

InProgress – This contact closes when the read command begins execution.

RFID_1:I:Channel[0].Busy – This contact will be open while the command is in process.

EQU RFID_1:I:Channel[0].Command = Upon completion of the command the interface block copies the value from output command to the input command. If the input command value equals the value of the command, the EQU output goes HI.

InProgress – This bit is unlatched when the command is successfully completed. The routine is now ready for the next RFID tag or other routine.

Chapter 9 RSLogix 5000 Code Examples

Clear Multiple Bytes

The Clear Multiple Bytes command clears multiple bytes of user data in a RFID tag. The user can specify the number of bytes to clear and the address from which to begin. This is very similar to a “copy” command. It copies the value you specify in the output data image Data[0] location to the addresses you specify.

Set the following values in the output image table:

a. xx:O.Channel[0].Command = 13 b. xx:O.Channel[0].Address = starting address c. xx:O.Channel[0].BlockSize = 0 d. xx:O.Channel[0].Data[0] = 0 (or value used to clear the byte) e. xx:O.Channel[0].Length = the number of bytes to clear f. xx:O.Channel[0].Reset = 0 g. xx:O.Channel[0].Timeout = 0 h. xx:O.Channel[0].UIDLow = 0 (or UIDLow) i. xx:O.Channel[0].UIDHi = 0 (or UIDHi)

Unless a UUID is specified, this command will operate 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 example routine below, the initialization in Rung 1 sets the address, length data, the value 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 value to be copied is initially stored in the controller tag CMB_Data. In the example below, CMB_Data is set to 0, but the user can set this to be any valid SINT value.

70 Rockwell Automation Publication 56RF-UM001A-EN-P - October 2011

RSLogix 5000 Code Examples Chapter 9

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. Note the counter is 31.

The Clear Multiple Byte command is executed successfully as the ChError = 0 and all the data bytes are zero. The counter increments to 32.

The tag is read again (command = 4) to confirm the clearing. Data bytes 2 through 4 are successfully set to 0.

Get Multiple Block Security Status

The Get Multiple Block Security Status command retrieves the security status of multiple blocks within a tag. It will also display 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].Length = the number of blocks to read. f. xx:O.Channel[0].Reset = 0 g. xx:O.Channel[0].Timeout = 0 h. xx:O.Channel[0].UIDLow = 0 (or UIDLow) i. xx:O.Channel[0].UIDHi = 0 (or UIDHi)

Unless a UUID is specified, this command will operate 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 example routine below, the initialization in Rung 1 sets the address, length data, the Data[0] value 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 starting address is block 0. The command reads 28 blocks (all the blocks of this RFID tag).

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 need to be in the field to complete the inventory command. By setting the output image fields to specific values, the Inventory command returns the following information:

1. Returns the number of tags in the field and the UUID of each tag. Set Address =0, Length = 0 and Data[0] = 0

2. Returns the number of tags in the field, the UUID and the DSFID of each tag. Set Address =0, Length = 1 and Data[0] = 0

3. Returns the number of tags in the field, the UUID and the DSFID of each tag that meets the specified AFI. Set Address =1, Length = 1 and Data[0] = AFI value. If the AFI value is 0, then all the tags are reported.

Set the following values in the output image table:

a. xx:O.Channel[0].Command = 20 b. xx:O.Channel[0].Address = 0 (or 1, see below) c. xx:O.Channel[0].Block = 0 d. xx:O.Channel[0].Data[0] = 0 (or 1, see below) e. xx:O.Channel[0].Length = 0 (or 1, see below) 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].UIDHi = 0

Notes:

1. Set Address = 0 to get all tags in the RF field.

2. Set Address = 1 to get all tags that have the AFI value specified in the

Data[0] location.

3. Set Length = 0 to get only the UUID for each tag.

4. Set Length = 1 to get both the UUID and the DSFID for each tag.

5. Set Data[0] = 0 to return all tags in the RF field.

6. Set Data[0] = AFI value (but not zero) to return only those tags that have

that AFI value

Example Routine

The example ladder diagram is initially set for Address =0, Length = 0 and Data[0] = 0. These values are then changed to get obtain example results for the three versions of the Inventory command.

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 below. The data shows the number of tags in the RF field and the UUID for each tag.

78 Rockwell Automation Publication 56RF-UM001A-EN-P - October 2011

Page 79

RSLogix 5000 Code Examples Chapter 9

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. The controller tag values are shown below. The data shows the number of tags in the RF field, the DSFID and the UUID for each tag.

Rockwell Automation Publication 56RF-UM001A-EN-P - October 2011 79

Page 80

Chapter 9 RSLogix 5000 Code Examples

In example 3, we get the tag information for only those tags the 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 below. The data shows the number of tags in the RF field, the DSFID and the UUID for each of these tags.

Lock AFI

The Lock AFI command will lock the one byte of information for the Application Family Identifier (AFI), preventing it from being modified in the future. Once the AFI byte is locked, it cannot be unlocked.

The AFI is used to group RFID tags by application. This allows the transceiver to send out an AFI and target only the tags that meet the application criteria.

Set the following values in the output image table:

a. xx:O.Channel[0].Command = 42 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 = UIDLow i. xx:O.Channel[0].UIDHi = UIDHi

The UIDLow and UIDHi bytes must be specified to lock the AFI value. The UUID can be found by performing the Inventory command.

80 Rockwell Automation Publication 56RF-UM001A-EN-P - October 2011

Page 81

RSLogix 5000 Code Examples Chapter 9

Example Routine

In the example routine below, 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

The following figure 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.

Errors

The following ChErrors will be generated:

• 0 – AFI was successfully locked.

• 4 – A tag with the wrong UUID entered the RF field.

• 8 – A tag that has already been locked entered the RF field.

Chapter 9 RSLogix 5000 Code Examples

Lock Block

The Lock Block command locks one block of user data, preventing future writing. Once the block is locked, the block cannot be unlocked. The transceiver automatically determines the block size of the RFID tag.

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].Length = 0 f. xx:O.Channel[0].Reset = 0 g. xx:O.Channel[0].Timeout = 0 h. xx:O.Channel[0].UIDLow = UIDLow i. xx:O.Channel[0].UIDHi = UIDHi

The UIDLow and UIDHi bytes must be specified to lock the block values. The UUID can be found by performing the Inventory command.

Example Routine

In the example routine below, the initialization in Rung 1 sets the address, length, the Data[0], UIDLow and UIDHi values used to lock the block and sets the command value to 0. The BlockSize, Reset, and Timeout are set to 0 in the output image table.

In the example routine, rung 1 initializes the output image table. The UUID is stored in a controllers tags UIDLow and UIDHi. The block that is being locked is block 26. This tag has a total of 27 blocks.

82 Rockwell Automation Publication 56RF-UM001A-EN-P - October 2011

Page 83

RSLogix 5000 Code Examples Chapter 9

Example Results

The output image table shows address 26. This is the second to last block of the Cat. No. 56RF-TG-30 tag. The command is 40. The UUID must be specified to lock any blocks.

After completion of the lock block command, the input image table should show the command is 40 and the ChError is 0.

Errors

The ChErrorfield will show will be 8 if you try to lock a block that is already locked.

Rockwell Automation Publication 56RF-UM001A-EN-P - October 2011 83

Chapter 9 RSLogix 5000 Code Examples

Lock DSFID

The Lock DSFID command will lock the 1 byte of information for the Data Storage Format Identifier (DSFID) area of the tag, preventing it from being modified.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. xx:O.Channel[0].UIDLow = UIDLow h. xx:O.Channel[0].UIDHi = UIDHi

The UIDLow and UIDHi bytes must be specified to lock the DSFID value. The UUID can be found by performing the Inventory command.

Example Routine

In the example routine below, the initialization in Rung 1 sets the address, length, the Data[0], UIDLow and UIDHi values used to lock the DSFID and sets the command value to 0. The BlockSize, Reset, and Timeout are set to 0 in the output image table.

84 Rockwell Automation Publication 56RF-UM001A-EN-P - October 2011

Page 85

RSLogix 5000 Code Examples Chapter 9

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 already locked, the ChError will be 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. The maximum number of bytes that can be read at a time is 160bytes using option flag 0, and 152 bytes using option flag 1.

•Option Flag 0 – Returns the specified user data. Set xx:O.Channel[0].Data[0] = 0.

•Option Flag 1 – Returns the UUID of the RFID tag and the specified user data. Set xx:O.Channel[0].Data[0] = 1.

Set the following values in the output image table:

a. xx:O.Channel[0].Command = 4 b. xx:O.Channel[0].Address = starting address to read c. xx:O.Channel[0].BlockSize = 0 d. xx:O.Channel[0].Data[0] = Option Flag e. xx:O.Channel[0].Length = the number of bytes to read 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].UIDHi = 0

This command operates only on the first tag in the field.

Note that Data[1] must also be set to 0.
