1.1 Overview

Task

1.1

Overview

Introduction
In many plants, especially for warehouses and conveyor systems, RFID (Radio
Frequency Identification) is used for tracking and identifying goods. Since the
topologies are becoming more and more decentralized, the connection of RFID
readers must meet this development. SIMATIC ET 200 systems are the common
decentralized periphery systems. In the course of this application, block libraries
(Identification_ET200) are provided which enable operating SIMATIC RFID
readers in a simple, user-friendly and cost-efficient way via SIMATIC ET 200. The
readers are connected to the SIMATIC ET 200 via serial communication modules
and controlled by a SIMATIC PLC via the blocks of the library.

Description of the automation task

SIMATIC RFID readers shall be operated via ET 200 systems for automatic
identification of goods in a warehouse. Three stations specify this warehouse
simulation: Incoming goods, Processing and Outgoing goods.

1 Task
1.1 Overview
Requirements of the automation task
Table 1-1
Requirements

Explanations

Incoming goods: RFID reader 1

In Incoming goods, TAGs are initialized via the

RFID reader with a certain byte pattern.

Processing: RFID reader 2

In Processing, TAGs are read and checked for the bit

pattern of the initialization. If the initialization has
been performed correctly, a time stamp is written to
the TAGs in order to simulate successful processing.

Outgoing goods: RFID reader 3

In Outgoing goods, TAGs are checked for the correct

processing time stamp. If successful, the goods have
passed through the warehouse without errors.

Reader reset and antennae

On/Off

In addition to the tasks of the warehouse, the readers

can also be reset manually and the antennas be
switched on and off.

Operation/visualization via an HMI

For each station in the warehouse there is a picture

on the HMI. The state and status of the reader jobs/
warehouse station are visualized in the pictures.

Siemens AG 2014 All rights reserved

The user can reset the readers of the three stations

and switch the antenna fields on and off via a
separate HMI screen.

Application requirements
This warehouse simulation example shall illustrate

how SIMATIC RFID readers can be connected to SIMATIC PLCs via ET 200
systems,

how the blocks of the Identification_ET200 library can be used.

2.

The TAG is initialized with a byte pattern.

3.

The DONE, BUSY and ERROR states are signaled by the status displays via
alarm displays on the HMI. Furthermore, the job status is output in form of
continuous text.

4.

The TAG is read and checked for the byte pattern of the initialization.

5.

If step 4 is successful, a time stamp of the CPU is written to the TAG.

Explanations on the sequence

In function block PROCESSING, the ET200MP-SP_READ library block is called
in the first network. It is interconnected so it automatically triggers the READ job
when a transponder is present in the antenna field (PRESENCE). The first 100
bytes of the user memory of the transponder are read here. In network 2, it is then
checked whether the initialization byte pattern (AF) exists in the receive buffer of
the READ block. If the byte pattern does not exist, an error is output (Error +
Status). If it exists, the current CPU time is read in network 3 and written to the
write buffer of library block ET200MP-SP_WRITE, which is called in network 5
and automatically starts the WRITE job to write the time stamp to the transponder.

checked whether the time stamp of station 2 exists in the receive buffer of the
READ block. If the time stamp does not exist, an error is output (Error + Status).
If it exists, a successful job processing is output (Done).
