6. Functional description
6.1 General information
LF reading devices are radio frequency identification systems that use radio transmission to read
or write data of LF transponders (134,2 kHz), which operate as tamper-proof electronic tags. The
LF reading devices communicate with common transponders (134,2kHz) according to ISO 18000-2
and ISO 11785 that are available on the market.
The data is transmitted via the existing interface with the preset transmission parameters. If several interfaces are available and connected to the host, the transmission is always carried out on the
most recently used interface. The data is embedded in a defined communication protocol and
exchanged between the reader and host.
6.2 Basic functions - operating modes
During normal operation, the LF reading device supports various basic functions:
• Heartbeat function, software version query
• Scanning of transponders in the antenna area (UID)
• Reading data
• Writing data
• Locking data
• Setting and reading out parameters
• Setting and querying inputs and outputs
The LF devices can be set in 3 other operating modes by setting the parameters: Polling operation
(optional), sensor-triggered automatic reading and test mode.
6.2.1 Normal operation
During normal operation, the LF reading device is immediately ready for operation after a reset. It
does not perform any automatic actions in this mode (standby). During normal operation, actions are
triggered by protocol commands from the host.
A scanning procedure or reading in the data area is initiated by a command of the host system
using the communication protocol.¬
In addition to the actions triggered by the host, a corresponding message can be automatically sent
to the host and an automatic reading operation can be started by activating or releasing a sensor.
When the reading operation is successful, the read data is immediately transmitted to the host. If
several antenna ports are occupied simultaneously, the reading operations are processed sequentially.
Writing actions (data saved to a transponder) are generally only possible via commands from the
host.
6.2.2 Polling mode
LF reading devices can be set into a continuous reading state, which is referred to as
polling mode. The device then performs reading operations at regular intervals and
outputs the corresponding data of the read LF transponder.
The reading device also continues carrying out protocol messages in polling mode. This
may, however, result in delays in the poll rhythm. The polling functionality is optional
customer-specific available!

www.hermos.com
www.hermos.com
The HERMOS LF reading devices support a test mode that facilitates setting up the antenna and
checking the reading ranges during commissioning. HF reading devices feature several DIP switches on the housing. These switches can be used to activate test mode.
The functions in test mode are described on a sticker located on the reading device housing. The
evaluation of the DIP switch depends on parameters
If the device is in test mode, the red status LED flashes at about 1 Hz. The yellow status LED then
indicates the status of the test mode. If the read or write process was unsuccessful, the yellow LED
flashes at the read or write frequency. If the read or write process is successful, the yellow LED
remains permanently lit.
With the existing I / O module, HERMOS LF readers with ASC-W1 protocol also show the successful or incorrect reading of the transponder at the respective first output port. See also behavior of
the output ports in test mode.

Component
Description
Power supply
connection
Three-pin socket for the connection of the 24V DC power supply.
Power-LED
The power LED indicates that the operating voltage is present and
the rea- ding device is ready for operation.
Status-LEDs
The two status LEDs are used for the reading and writing feedback in
test and polling mode. If the device is in test mode, the red status
LED flashes at about 1 Hz. The yellow status LED then indicates the
status of the test mode. If the read or write process was
unsuccessful, the yellow LED flas- hes at the read or write frequency.
If the read or write process is successful, the yellow LED remains
permanently lit.
In normal operation, if an error occurs, the display of this
occurs via the red LED:
Red LED constantly on: read error (no tag)
red LED flashing rapidly: antenna error (tuning, cable
break). This display will reset automatically with the next
valid reading.
After a restart, a short self-test of the LEDs, then display of the
protocol: SECS: The red LED goes on briefly
ASCII: The yellow LED goes on briefly
DIP-switch
DIP-switch 4 starts an automatic antenna
tuning. DIP-switch 3 activates a test
mode.
DIP-switch 1 and 2 serve the antenna selection.
Ethernet interface
The reading device features an Ethernet interface depending on the
de- vice model. The communication with the device can be carried
out via the 10/100 BaseT interface.
RS232 interface
Depending on the device model, the reading device features a RS232
in- terface. The communication with the device can be carried out via
the serial interface (9-pin Sub D)

9. Operating
9.1 Operating personnel
The device should only be operated by specially trained personnel. If you have any
doubts about the required qualifications, please contact the manufacturer.
The operation of the device without special expertise can result in damages to the
device or on connected devices.
9.2 Protocol change
9.2.1 General
To communicate with a connected host system, the reader supports ASCII or SECS /
HSMS protocols. The protocol selection takes place by means of automatic protocol
recognition.
The currently set protocol is displayed on the status LED during the boot process.
SECS: The red LED goes on briefly after self test
ASCII: The yellow LED goes on several times
9.2.2 Automatic protocol detection
The reader automatically adjusts to the protocol used by checking and evaluating the first
message after a reset. The interface is changed accordingly when the protocol is changed
and reinitiali- zed. This process can take several seconds. Already sent messages are lost.
The newly recognized protocol is used for further communication. A renewed change is
only pos- sible after another reset. Automatic protocol detection can be disabled by setting
parameter 98 (0x62).
If the reader receives undefined or random characters, this may result in an
accidental protocol change.
Automatic protocol detection can be deactivated in parameter 98 (0x62).

9.3 Addressing the antenna port
The reader LFM 4x is equipped with 4 antenna ports. Each of these ports has its own
antenna tuning with which the connected antenna is tuned to the ambient conditions.
In the set protocol, the read or write commands are always executed by port. The 4 antenna
ports from 1 to 4 are numbered consecutively and are addressed accordingly in the logging
command.
In the ASCII protocol, the reader ID decides on the selection of the antenna port.
The reader ID („1“ to „4“) responds to the respective antenna port 1 to 4. Depending on the
Factoryparameterset, it is possible to select the value range of the reader ID from „0“ to „3“ or
from „1“ to „4“.
In the SECS protocol, the target ID is used to select the antenna port: Target ID „01“ to „04“
responds to the respective antenna port 1 to 4.
For customer-specific solutions, another reader (eg HFS ESN) can be connected to the
RS232 interface. This reader is then used to communicate via the Target ID „05“ or Reader
ID „05“.

The antenna is addressed by the ReaderID „0“ to „3“, or TargetID „1“ to „4“. For SECS
protocol there is no MID area defined.
The rs232 connector can be used for serial host communication.
For the TCP/IP communication the complete end packet of the ASCI-I1 protocol will be
transmitted (end character and 4 bytes checksum).
P-command: The parameter value will be interpreted as hexadecimal value.
The additional F-command can be used to deliver the parameter value with hexadecimal
interpretation. X/R/W-command: The page value will be interpreted as hexadecimal value.
Errors will be send with the command “E”. With default settings a confirmation has to be
send. The additional B-command can be used for signal the detection of an object.
Factoryparameterset 4: (standard ASC-I1 mode)
The antenna will be addressed by the ReaderID „0“ to „3“ or TargetID „1“ to „4“.
For the SECS protocol, the standard MID range of 2 pages / 16 characters is defined. The
RS232 port can be used for serial host communication.
Factoryparameterset 5: (standard ASC-I1 mode)
The antenna will be addressed by the ReaderID „0“ to „3“ or TargetID „1“ to „4“.
For the SECS protocol, the standard MID range of 2 pages / 16 characters is defined. The

If there is no transponder in the reading range of the antenna, the reader repeats the reading
function several times before an error message is sent. The number of repetitions is defined in
parameter 4 (‚r / w maxrepeat‘). If reading is still not possible, the reader sends the error
message ‚no tag (4)‘ to the host after the repetitions have been carried out.
No confirmation is expected from the host.
For a multipage read request (98 or 99), the protocol is retried. At the end of reading, the
reader sends an additional packet.
If the sensor check is activated (parameter 1: readmode), the assignment of the external input
is checked before the initiation of a read process by the host. The reading process is only
started if the sensor is occupied, otherwise the error message ‚no tag (4)‘ is sent.
10.4.2 R – Automatic read
By assigning the external input, an automatic read operation can be triggered.
The command „R“ sends the read data to the host. The host then has to confirm the
message. Depending on the setting of the reader (parameter 1: readmode), the reader
reads the following pages:

When reading several pages (par. 1: readmode „tag“ or „everything“) the command is repeated
for each read page. The last package contains the command ‚R‘ and the reader ID.
The host expects a confirmation of the read data. If there is no confirmation from the host, the
command is repeated. (par.5: ‚RS232 repeat time‘, par.6: ‚RS232 maxrepeat‘).
If a reading is not possible, the reader automatically repeats the reading with the set
parameters. (par.3: ‚r / w delay time‘, par.4 ‚r / w maxrepeat‘).
If no reading is possible, the reader sends the error message ‚no tag (4)‘ to the host.
The delay time for the presence sensor can be set (parameter 0: ‚sensor delay‘).
An automatic reading is only possible if all messages to be confirmed have been confirmed by
the previous reading or the waiting time (par.5: ‚RS232 repeat time‘, par.6: ‚RS232 maxrepeat‘)
has elapsed after the last transmission.
10.4.3 W - Write data
The command W starts writing a defined data area of a transponder.
If there is no transponder in the write range of the antenna, the reader sends an
error message (error 4 - no transponder).
If the describing of the tag fails, the reader repeats the writing operation several times before
sending an error message. The number of repetitions is defined in parameter 4 (‚r / w
maxrepeat‘). If writing is still not possible, the reader sends the error message ‚no tag (4)‘ to the
host after the repetitions have been carried out.
If the sensor check is activated (parameter 1: readmode), the assignment of the external input
is checked before the start of the write process by the host. The write process is started only
when the sensor is busy, otherwise the error message ‚no tag (4)‘ is sent.

The command „P“ can be used to change the value of individual parameters. After a
parameter has been successfully changed, the reader sends a confirmation message.
Depending on the Factoryparameterset selected, the data elements parameter number and
parameter value must be interpreted differently. For single-digit hexadecimal parameter no. the
following interpretations must be observed:
In the standard ASC-I1 protocol mode the data element „Parameter Value“ with decimal values
(00-99) has to be used. The values for the data item „Parameter No.“ are hexadecimal values
(0-F).
Only in ASC-W1 mode (Factoryparameterset 3) the data elements „Parameter No.“ and

A single page of a multipage transponder can be disabled. The page can still be read, but not
rewritten. The process cannot be reversed.
If the lock of the transponder page fails, the reader repeats the procedure several times before
an error message is sent. The number of repetitions is defined in parameter 4 (‚r / w
maxrepeat‘). If writing is still not possible, the reader sends the error message ‚no tag (4)‘ to the
host after the repetitions have been carried out.
If the page was already locked, a positive confirmation will be sent (same as the first block).
If the sensor check is activated (parameter 1 readmode), the assignment of the external input is
checked before the blocking process is started by the host. The locking process is only started
when the sensor is occupied, otherwise the error message ‚no tag (4)‘ is sent.

10.4.13 I – Adjust RF module
It is necessary to adjust the RF module in ordert to adapt an antenna tot he ambient conditions
optimally. The tuning achieves an optimal read / write range for the present installation
environment. Tuning is performed one at a time for each antenna port and the determined
tuning value is stored for each antenna.
For optimal results, the vote should be automatic, but the voting value can also be set
manually.
To start the auto-tuning process, select the value 08.
Example: I108 … automatic tuning of antenna 1
If the reader can not determine the appropriate calibration, the error „5 - Invalid“ is sent instead
of the confirmation.

11.SECS / HSMS Communications protocol
The SECS I standard defines a communication interface that is suitable for exchanging
messages between the semiconductor processing systems and a host. A host is a computer or
computer network that exchanges the information with the systems to carry out the production.
The standard does not define the data contained in the message. The meaning of the
messages must be defined by a standard that defines the message content – e.g. by the SEMI
Equipment Communications Standard E5 (SECS-II).
This message record describes the communication between a reading device with SECS-I and
a host. The host and the RFID reading device can communicate via a RS232 interface (SECS-I)
or an Ethernet interface (10/100BaseT) with HSMS protocol. The meaning of the messages is
provided in the message details section in which the message content is defined.
Serial communication (SECS-I):
The data is transmitted or received as a serial bit stream with 10 bits per character in a
supported data rate. A standard character has a start bit, 8 data bits and a stop bit. No parity
bits or other controls are used for transmitting the individual bytes.
Default setting: 19200 / 8N1
Details about the data definition and the data transmission are provide in the SEMI Standard
E4. (SEMI Equipment Communication Standard 1 Message Transfer SECS-I)
Ethernet communication (HSMS):
The reading device functions as a HSMS server. This means that it waits for a connection
request from a HOST PC (client).
TCP/IP: IP-Adress xxx.xxx.xxx.xxx Port 3241
If there is a connection request from a HOST, a HSMS connection is set up and the SECS II
messages defined in the message record are transmitted from the reading device to the
respective HOST and vice versa. The HSMS connection remains intact until it is specifically
terminated by the host or the reading device.
All reading devices available in the network (LAN) can be operated from any HOST PC. A
HSMS reading device, however, can no longer be connected to more than one HOST
simultaneously.
The network settings can be changed using a configuration tool provided by HERMOS. Each
change to the network settings causes the unit to reboot and thus disconnects existing
communication connections.
11.1 Structure of a message
The communication structure and process is defined by the SEMI Equipment Communications
Standards E4, E5 and E37 (SECS-I, SECS-II, HSMS).
SECS message blocks always have a specified structure that consists of 1-4 length bytes, 10
bytes of message headers and message data.

The length contains all the bytes transmitted after the length byte with the exception of the two
checksum bytes. The maximum block length allowed by the SECS-I is 254 bytes and the
minimum is 10 bytes.
The reverse bit (R bit) indicates the direction of the message. The R bit (MSB) is set to „0“ for
messages to the reading device and „1“ for messages to the host.
The device ID is a unique number to establish the connection with the reading device. It
consists of an 8-bit gateway ID (bit 0-7) and a 7-bit reader ID (bit 8-14). The gateway ID in the
delivery state corresponds to the last two hexadecimal characters of the serial number of the
reader. The reader ID has the value 0x01 in the delivery state. Of course, the device ID can be
changed via the corresponding parameters Gateway ID and Reader ID within the validity range.
See example with Reader ID 0x01 and Gateway ID 0x00:

The W bit indicates whether the transmitter of the primary message wait for a reply. If the W bit
contains the value 1, it means that a reply is expected.
The message ID determines the format and the content of the transmitted message. It consists
of a stream and a function. The stream defines the message group and the function, the exact
meaning and the syntax of the message. A primary message (request) is defined as an
uneven message. A secondary message is defined as an even message (reply).
The end bit indicates whether a block is the last block of the message. A value of 1 means
that the block is the last block. Since all messages can be transmitted in a block, the block
number always has the value 1.
The system bytes in the header of each message are used to distinguish primary messages.
The system bytes of the reply message must correspond to the system bytes of the
corresponding primary message. The system bytes are incremented for each primary
message.
The checksum is calculated as the numerical sum of the unsigned binary values of all bytes –
after the length byte and before the checksum as well as in an individual block.
For more detailed information about the structure and transmission procedure, see SEMI E4,
E5, E37, E99.
