Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

Introduction
1
Purpose of this operating manual
This manual describes the communications procedure of the SIMATIC RF200 readers with
the ASCII protocol (article numbers: 6GT2821-xAC40).
With the ASCII protocol, you can connect RF200 readers to any control systems with an RS-
232 interface quickly and easily. This document describes not only the protocol definition and
the possible interface parameters but also the command frames of the RF200 ASCII readers
(e.g. read and write from/to transponders). The section "Transponders" lists the ISO15693
transponders of the RF200 portfolio along with their memory configuration.
Target group
This manual is intended for application developers who want to operate the RFID system
“RF200” on controllers or host systems with the RS-232 serial interface.
Registered trademarks

Introduction
1.1 Properties of the protocol
ASCII protocol for RF200
6Operating Manual, 11/2016, C79000-G8976-C329-04
1.1
Properties of the protocol
This protocol represents a simple communications procedure for a point-to-point connection.
The communications parameters of the serial interface are set as follows in the factory:
●Data frame with 8 data bits 1)
●1 stop bit 1)
●Odd parity
●Transmission speed: 19.2 kBd
1) This value cannot be changed in RF200 readers.
Full duplex data transfer is possible. Since no handshake is defined, both stations can send
at the same time.
The net data is transferred with the ASCII characters '0' to '9' and 'A' to 'F'. Other characters
are not permitted. For the frame, two uniquely recognizable control characters are used,
"STX [02]" for the start of the frame and "ETX [03]" for the end of the frame.
With the ASCII protocol, a third optional control character "LF [0A] = new line" (before ETX)
is possible. The reader understands this control character, configuration on the reader is
unnecessary. A frame is uniquely identified by the control characters for the start and end,
the procedure has no other reliability mechanisms or length information. The amount of data
to be transferred is restricted by the monitoring time and by the length byte in the frame.
Receipt of the frame is monitored with a monitoring time of 300 ms. If the host does not
manage to send the next character to the reader within this time until "ETX" is reached, the
frame is ignored.
Note
Restrictions resulting from the ASCII protocol
The ASCII protocol has no data consistency mechanisms. You should take this into account
in your application (e.g. checksum).
The ASCII protocol has no line monitoring mechanisms. Execute the "SLG
-STATUS"
command (mode 0) at regular intervals, to ensure th
at the reader is reachable.

Introduction
1.2 Interface parameters
ASCII protocol for RF200
Operating Manual, 11/2016, C79000-G8976-C329-04 7
1.2
Interface parameters
You can select the following interface parameters:
●Transmission speed:
–19.2 kBd (default),
–57.6 kBd,
–115.2 kBd
●Parity:
–without,
–even,
–odd (default)
●Stop bits:
–1 (default),
–2
The reader stores these parameters retentively. You can modify these parameters using the
"SET RS232" command and read them out using the "SLG-STATUS" command.
NOTICE
Documenting changes to the interface parameters
Document all changes that you make to the interface parameters. You can only read out
data when the interface parameters set in the driver and on the reader match.
If you cannot use the reader with the default settings, follow the steps below to change
settings of the serial interface:
1. Connect the reader to a PC.
2. Send the interface frame "SET RS232" using a standard PC tool (e.g. HyperTerminal).
The reader can then be deployed in the target environment.
Note
Run "SET-RS232" before the first "RESET"
To change the interface parameters, the "SET RS
-232" command must be sent before the
first "RESET" command. The acknowledgement of the command is still made with the
or
iginal interface parameters; following this the reader is ready for operation with the new
parameters.
Make sure that you perform this procedure when necessary with all readers since all readers
ship with the default transmission speed 19.2 kBd.

Introduction
1.3 Specifications for data transmission
ASCII protocol for RF200
8Operating Manual, 11/2016, C79000-G8976-C329-04
1.3
Specifications for data transmission
The data transfer must meet the following specification:
With each byte, first the high nibble and then the low nibble are transferred.
e.g. in the case of 0x87: first character →0x38; second character →0x37.
"Words" represented in the frame structure are transferred first with the MSB. These "words"
contain, for example, the length and address information for write/read commands. The net
data is treated as bytes.
To ensure that the handling remains simple, the chaining of commands was dispensed with
in the ASCII protocol. A command is always followed by the corresponding
acknowledgement that must arrive before new commands can be sent. This means that
interface communication remains simple.
Only one command can ever be active on the reader. This rule does not apply to the
following commands:
●The "RESET" command can be sent at any time to re-initialize the reader.
●The "SLG-STATUS" command can be queried at any time.
Since the sender of an ASCII frame has no information as to whether the frame has arrived
at the other node, the new command "SLG-STATUS" (mode 0) was defined with which the
reader can be queried to establish whether a command is active or not or whether a
transponder is located in the antenna field or not.
Over and above this, the command can also be used to implement line monitoring.

2.1
Overview of commands
The ASCII protocol supports the single tag mode with normal addressing. The following
modes can be selected:
●with presence (MDS_Control On)
●without presence (MDS_Control Off)
●without presence including command-dependent antenna on/off (MDS_Control, HF Off)
If the presence check is active "with presence", transponders entering the antenna field are
displayed. The presence of a transponder is signaled by the reader LED being lit yellow. The
presence of the transponder is signaled to the host system using the presence frame. You
will find more information on this in the section ""ANW-MELD" message (Page 19)".
With the passive presence check "without presence", the presence of a transponder is also
indicated by the yellow reader LED lighting up, however no frame is sent to the host system.
In this mode, presence can be queried on the reader by the host with the "SLG-STATUS"
command (mode 0).
Table 2- 1 The following commands are supported:

Byte 9 0x30 / 0x31
With the active presence check, if there is a change in the presence status, the reader sends
a frame with the number of transponders in the antenna field. If a transponder leaves the
field at the same time as another transponder enters the field, two "ANW-MELD" messages
are sent.
Note
Reachability of the host
The presence message is asynchronous (i.e. without a request from the host).
This means that the host must always be ready to receive and must make suitable buffers
available so that the message ca
n be processed immediately.
