6. Functional description
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 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.
Basic functions - operating modes
During normal operation, the LF reading device supports various basic functions:
Heartbeat function, software version query  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!
6.2.3 Sensor-triggered operation
Device versions with IO port offer the function of a sensor-triggered automatic reading operation. The reading device automatically performs a reading operation when the input is triggered. The type of action

LFM LP Reader 15.01.2019
Page 16 of 119
(inventory/reading) can be defined with the parameters „Read mode“ and „Read page“. The read data is automatically sent to the host. The result of the reading operation (successful, not successful) can be optionally output via I/O s of the antenna port.
6.2.4 Test module
The HERMOS LF reading devices support a test mode that facilitates setting up the antenna and checking the reading ranges during commissioning. These test mode can be activate with a push button.
If the device is in test mode (maintenance mode) three tri-colour LEDs shows the state of the test mode. The chapter "Status LEDs" describes the behaviour in test mode.

7.6.2 Test push button
If the button is held pressed for a defined time (->parameter 56+57), the status of the button is changed. If the state changes from "Off" to "On", the test mode Read is started when the Test push button is enabled
(->parameter 36). If the push-button is then held without interruption for a further defined period of time (-
>parameter 56), it switches to the Write test mode. If the state of the button changes from "On" to "Off", the
test mode Read or Write is terminated. The current state of the test mode is indicated by a unique status LED (->Status LED).
Status LEDs
Status LEDs: The status LED is a tri-colour/RGB LED. The white or blue status LED indicates the status of the test mode. If the reader is in maintenance mode or the reading test mode is running, the white status LED flashes at about 1 Hz in reading testmode and 2 Hz in maintenance mode. If the reader is in maintenance mode and the writing test mode is running, the blue status LED flashes at about 1 Hz. If the reader is in normal operation mode, the green status LED is permanently shining (->parameter 35).
Test LEDs: The test LED is a tri-colour/RGB LED. The red and green Test LEDs are used for the reading and writing feedback in test or polling mode. If the read or write process is successful, the green test LED remains permanently lit. If the read or write process fails, the red test LED shines.
In normal operation mode the red and green test LEDs are used for the last reading and writing feedback. In this mode the red or green test LED will light for 5 seconds (->parameter 84) after the last reading.
Tuning LEDs: The tuning LED is a tri-colour/RGB LED. The red and green tuning LEDs are used for the tuning feedback. After a successful antenna tuning, the green tuning LED is switched on for 5 seconds (->parameter 84). If no valid antenna tuning is found during antenna tuning or if an invalid tuning is detected during a read operation, the red tuning LED flashes quickly for 5 seconds (->parameter 84 and 85). During automatic antenna tuning, the blue tuning LED flashes.
After a powerup reset, the Tri-Colour LEDs undergo a short self-test and then display the set communication protocol for one second: SECS: The red status LED goes on briefly ASCII: The red test LED goes on briefly
RS232 connection
The serial interface is implemented as a Sub-D plug connector (9-pin, female). A serial connection line (1:1 circuit) can be used.

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 (->Status LEDs) during the boot process.
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 reinitialized. 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 possible after another reset. Automatic log detection can be enbaled or disabled with parameter 98.
9.2.3 Triggered protocol change
During a powerup reset a protocol change can be performed. To do this, press and hold the test and tuning button during the powerup reset until only red LED lights up at the end. If the red test LED is lit then the protocol has been changed from SECS to ASCII. If the red status LED is lit then the protocol has been changed from ASCII to SECS.

10. ASCI-I1 Communication protocol
The ASCI-I1 communication protocol defines a simple communication interface that is suitable for exchanging messages between a HERMOS reader and a host. A host is a computer or computer network that exchanges the information with the systems to carry out the production.
Serial communication:
On serial communication the ASCI-I1 message is transmitted with 4 bytes checksum. The data is transmitted or received as a serial bit stream with 11 bits per character in a supported data rate. A standard character has a start bit, 8 data bits, a parity bit and a stop bit. An even parity bit is used for transmitting the individual bytes.
Default setting: 19200 / 8E1
Ethernet communication:
On default the reading device functions as a server. This means that it waits for a connection request from a HOST PC (client).
TCP/IP: IP-Adresse xxx.xxx.xxx.xxx Port 3241
After a connection is established, the ASCI-I1 messages defined in the message record are transmitted from the reading device to the respective HOST and vice versa. On default settings ASCI-I1 messages are transmitted without any checksum. The 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 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.
Structure of the communication protocol
The communication is carried out via ASCII packets. After each command to the reading device, a specific reply is transmitted. We recommend waiting for this reply before transmitting a new command.
Packet content
Each message packet consists of a packet header (header = 3 characters), the message data (2 or more characters) and the packet end.

10.4.1 X – Read data
The command X starts reading of the data area from a transponder.
If there is no transponder in the read range of the antenna, the reader sends an error message (error 4
- no transponder). The data element "page" can have the following values.
1) „E“ or „F“ in ID, Bit 0…3 of the read ID
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 multi-page 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:
Read Mode:
0 Reading the page defined in parameter 2 1 sequential reading of a transponder to the end character
('E' - end character or 'F' empty) in ID bit 0 ... 3
2 Reading the entire transponder (all 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 delay 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.6: 'RS232 repeattime') 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.
10.4.4 G Query parameter

10.4.6 P – Set parameter
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 customer mode selected, the data elements parameter number and parameter value must be interpreted differently:
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
For two-digit hexadecimal parameter numbers, the value parameter must always be sent in two digits hexadecimal.

10.4.7 N – Reset
The command N performs a reset of the hardware/software of the reader.
After performing the reset operation, the device sends a confirmation message.
After a hardware reset, a confirmation ("n0") is sent to the host. If TCP / IP is used as the interface, it will not be received because an existing TCP / IP connection is interrupted by the reset.

This message is only available in standard ASC-I1 mode!
If an error occurs the device will send an error message with the respective error code. This message must be acknowledged by the host
Further information about error codes and the corresponding measures can be found in the chapter
Error Codes.
10.4.9 H – Heartbeat
The command "H" sends a heartbeat request to the reader. The reader responds with its serial number and a response code.
The heartbeat function can be performed for all 4 antenna ports (1-4). If another reader is operated as a customer variant on the RS232 port, a heartbeat can be sent to the external reader via reader ID "5". The response code is part of the protocol but is not used for this device. The response code is always '0000'.

Page 52 of 119
10.4.11 L – Lock data area
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.

10.4.12 I – Adjust RF module
It is necessary to adjust the RF module in order to adapt an antenna to the ambient conditions optimally. The tuning achieves an optimal read / write range for the present installation environment.
Tuning is performed one at a time for the antenna port and the determined tuning value is stored for the 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 10 .
Example: I110 … automatic tuning of antenna 1
If the reader can not determine the appropriate calibration, the error "5 - Invalid" is sent instead of the
confirmation.

The command "J" can be used to query the tuning values of the individual antennas. Each antenna port has its own tuning value.
The tuning value is a set value for the optimal antenna tuning. For optimum read and write ranges, the value is automatically determined by the reader (I-message). The value is measured in 16 steps (00-0F).

The Q command can be used to query the current status of all outputs. The status of the outputs is
queried in a message. In the current version, the value of the data element Head-ID always has the
value "1" for the outputs.
Example: Status LEDs >> Q01 << q012000000001 external LED (2 = flash), green status LED (1 = on)
The status of the input sensor can be queried via head ID „0“. In this case, the answer contains the sensor state (0 -1) instead of the 10 output states. Example: Status of input sensor >> Q00 << q000

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-Adresse 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.
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 (->Parameter 0) and Reader ID (->Parameter 0x0B) 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.
