RFID is a technology to automate processes. Information is being incurred automatically and randomly (transponder data and other) and must be processed in the very same moment (real time). In addition the information has to be verified and conditioned in a way that conventional business applications (like SAP and other) are able to work with that data. Software that is dedicated to do this is called RFID middleware. It is the interface between RFID infrastructures and IT systems. It is not possible to connect RFID readers directly with e.g. a Warehouse Management System or similar.

A single RFID Control Unit can manage up to 100 readers or antennas respectively.

The readers are connected via TCP/IP network or serial.

The RCU does not need any operating, nor does it need maintenance. It is supplied with a PC based software tool called identVUE. identVUE is used to centrally set up, configure and commission RFID solutions. The configuration for a RFID project is then loaded up to the respective Control Unit. That’s all.

The RFID software embedded in the RFID Control Unit is based on powerful algorithms that e.g. securely blank out unwanted transponder readings caused e.g. by reflections of the radio signal on metal surfaces. The RCU is especially helpful with demanding radio conditions. Another example is separating transponders that are located next to RFID gates – i.e. “static” tags – from transponders passing through the gate and blanking them out without need for expensive shielding efforts.

Yes. Via the configuration and commissioning tool identVUE (supplied with the RCU) all sensors and actuators (I/Os) are configured and managed. The I/Os can be connected to suitable readers or to the RCU.

No. Via the configuration and commissioning tool identVUE logical read zones are defined that make the RFID Control Unit blank out readings from a wrong dock door without need for shielding.

Yes. The RCU is independent of the auto ID technology used.

Yes. The RFID Control Unit supports interrogators of renowned manufacturers.

Yes. Every reader specific configuration is stored in the RCU. You can replace the broken device without need for configuration or programming (hot-swap).

Servers, PCs, ERP systems, etc. do not operate in real time and cannot process RFID data in good time. In addition when using more than one reader umbrella intelligence is needed for coordinating the readers and for allocating transponder readings correctly as e.g. metal causes unwanted readings through reflections.

The RFID Control Unit identIQ is very flexible and links to almost any system via the following interfaces:

• SQL/ODBC via PC besed service or gateway
• SMTP
• TCP/IP, UDP
• RS232
• Universal C-API for customized software applications
• Optional: SAP via gateway
• Optional: SIMATIC© S7

The RCU identIQ is connected to the superior system via Ethernet. Various interfaces are available (see previous question).

Yes, via an optional SAP gateway.

Yes. Via optional software the RCU identIQ can communicate directly with SIMATIC© S7 PLC. MPI (Multiple Protocol Interface) and Industrial Ethernet via respective Ethernet CPx43 are supported. A simple project planning defines which RFID data like e.g. the EPC and the time stamp are transmitted to which storage block of the S7 control. During operation the selected information is then automatically transferred to data blocks and markers. No programming in Step 7 is needed.

Some readers have functions integrated for processing transponder data. However an intelligent reader is intelligent only for itself – it does not know of other readers within a RFID installation. This makes it difficult to handle false readings at e.g. adjacent dock doors (RFID gates). Also programming on the reader protocol level is required for installation. The RCU identIQ with its efficient RFID software is the top layer keeping the general view and generating validated data. It also integrates without programming needs.

When there is only one reader in your application you may want to use the RFID gateway identIQ.mini. It also avoids programming or handling reader protocols.

No. Depending on the number of antennas connected to a RCU there is a single charge for a lifetime license.

No. There are no moving parts in the device. The RCU identIQ can be installed next to the equipment.

Yes. The RCU identIQ enables execution of individual software.

Yes. The RFID software of the RCU identIQ provides a Application Programming Interface as Windows DLL (C-API).

Yes. There is a software option that enables the RFID Control Unit for direct communication with SIMATIC© S7 PLC (see also question 16).

No. RFID projects are set up and configured with the identVUE tool and uploaded to the RCU. However identIQ offers ports to connect a monitor and keyboard. This can be helpful with e.g. stand alone RFID applications.

The RCU identIQ runs on 9-36 VDC. It comes with an appropriate power pack to connect to the 220V power supply system.

Yes. You can use several RFID Control Units in one project.

Under a maintenance contract you will receive updates of the firmware free of charge. We inform you when an update would bring advantages for your application.

A maintenance contract entitles you to automatically benefit from hardware and software improvements. You will receive quick on-site troubleshooting when required. Broken devices will be replaced free of charge as the fixed rate includes spare parts. Also any additional cost for travel and mileage can be avoided with a maintenance contract. The maintenance contract protects your budgets from unforeseen repair costs.

Yes. IdentPro offers leasing for the entire product and service range. Just ask for your personal offer.

That of course depends on the individual situation. Usually the ROI with RFID projects is achieved in approx. one year.
