Overview Safety

A safety-inspected power cable that satisfies the regulations of the country of use is required for the device. Devices with metal housings must only be connected to a grounded, shock proof socket.

The device must not be operated unless the nominal voltage of the device matches the local supply voltage. Check the supply voltage of the device in stationary devices.

When connecting and disconnecting wires, refer to the instructions in the operating instructions for the device.

Do not use any damaged wires (damaged insulation, exposed wires). A faulty wire poses a risk of electric shock or fire hazard.

Polarity reversal or otherwise faulty connection can damage the LPR1DHP station. In that case the station must be send to the SYMEO service.

During installation, make sure that no objects or fluids enter the device (risk of electric shock, short circuit).

In emergencies (e. g. if there is damage to the housing, control elements or the mains cable, if fluids or foreign bodies have infiltrated the equipment), switch off the power supply to the device immediately and notify your SYMEO Service.

Protect the contacts of all of the device's sockets and plugs from static electricity. Do not touch the contacts. If it is ever necessary to touch the contacts, take the following precautionary measures: Touch a grounded object or carry a ground strap before touching the contacts. This will divert static charges.

Proper operation (in accordance with IEC60950/EN60950) of the device is only assured if the housing and integral covers for mounting slots are fully installed (electric shock, cooling, fire protection, noise suppression). If necessary, refer to the corresponding instructions in the operating instructions for the device.

In the case of high outside temperatures and intense, direct solar radiation or other radiant heat, it may be necessary to provide a sun or heat shield.

Data links to peripheral devices must be provided with adequate shielding.

For LAN cabling, the requirements in accordance with EN 50173 and EN 50174-1/2 apply. Use of either a Category 5 shielded cable for 10/100 Ethernet or Category 5e shielded cable for gigabit Ethernet is a minimum requirement. The specifications of standard ISO/IEC 11801

2 Overview of the LPR-1DHP system

An LPR-1DHP system consists of two units named BS and TS that conduct the measurements. One unit (BS) initiates the measurement and the second unit (TS) replies. Both units are shipped in a pre-configured set. Unit BS1 is configured to measure with TS1, BS2 with TS2 and so on. The distance values are only available on the unit labeled BS. Consequently, the unit BS must be mounted at the position where the distance values are required, e.g. on the crane-bridge. Figure 1 shows the complete system including mounting bracket for mounting on tubes.

Port number of the TCP/IP port designated for sending and receiving data from serial port (ttyS2). ttyS2 is the port for the parameterization interface (Service Port, default: 3045)

ttyS3

Port number of the TCP/IP port via which the data from serial port (ttyS3) is sent and received. ttyS3 is the port for the data interface (Binary Port, default: 3046)

IP (Server)

For all active connection types the IP-address of the server is required to which the connection should be established.

Data Port

Port-Number of TCP/IP Port. Data of serial interface (ttyS3) is sent and received. ttyS3 is the binary port. Default value is

3046.

Reverse Port

For all active connection types a reverse channel for data transmission is required.

Packet Filter

If selected type “Fixed Frame” it is possible to filter packed

data. Default value is „none”. Example: “2,3” filters the data type 0x02 (Send request) and data type 0x03 (relay switching command).

Receive Size

If selected type “Fixed Frame” it is possible to set the frame

size of the received data packed. Example: For 1Dapplication a frame size of 15 Byte is sufficient. A smaller telegram must me filled with 0x00.

Send Size

If selected type “Fixed Frame” it is possible to set the frame

size of the sent data packet. Example: For 1D-applicaiton a frame size of 21 Byte is sufficient. A smaller telegram is filled with 0x00 by the LPR-1DHP station.

8 Protocol XP Description for TCP/IP and RS232

8.1 General Description

This protocol is the interface between a LPR-1DHP station and the user. The binary protocol XP protocol provides information in high density. Its structure ensures a simple implementation. The transfer is done in single data frames.

The interface for the binary protocol XP can either be a serial (RS232) interface or a TCP/IP or UDP interface. The baudrate of the serial interface must be set to 19200 baud.

8.1.1 Structure of Data Packet

The binary protocol XP was originally designed for transmission over RS232 interfaces. When the protocol is used on a RS232 interface each data packet starts and ends with a

reserved symbol. This reserved symbol cannot appear in the data stream. Figure 1 shows the general structure of the data packet.

Figure 1: Structure of data the packet

The START and the STOP-field is in each data packet the reserved symbol 0x7e and 0x7f. TYPE indicates the type of the data packet. Therefore up to 256 different types can be defined . The TYPE-field is followed by the DATA-field. The DATA field contains the real data of the packet of the type TYPE. The CRC-field contains a check sum. The check sum is applied to all previous data fields except the START and END data field.

All multi-byte integers (e.g. CRC field) are encoded in Network-Byte-Order (Big Endian).

8.1.2 Byte Stuffing

The two symbols 0x7E and 0x7F are unique for START and STOP-fields. If these symbols occur within any other field (TYPE, DATA or CRC), they must be replaced by the following order:

This byte stuffing scheme ensures that the receiver of the protocol can identify definitely the START-field within a flow of data, even if the symbol of the start field occurs within the DATA-field.

Example: If the symbol 0x7d is read, it must be cancelled. The following symbol must be XOR combined with 0x20 to recreate the original symbol.

Protocol XP Description for TCP/IP and RS232

Byte stuffing is deactivated for the fixed frame protocol (compare chapter

8.3).

8.1.3 CRC

The CRC-16-IBM with polynomial x16+x15+x2+1 is used for the CRC. The CRC is calculated over all data fields (TYPE and DATA), but not for the START and END field.

The CRC-calculation is only applied to the original symbols. The appropriate calculation for coding must applied before byte stuffing. If receiving the data from the LPR-1DHP system the byte stuffing must be resolved to get the original symbol. Then the CRC is updated with the original symbol.

8.3 Binary protocol XP over TCP/IP: Fixed Frame Protocol

If the LPR-1DHP station has a TCP/IP interface two options are available for the protocol. Either you use the protocol as it is sent from the serial interface (with different data type lengths, byte stuffing) or you use a fixed frame protocol.

In the first case the data symbols 0x7e und 0x7f (which are reserved for the START and END field) are replaced (see chapter 8.1.2.) Byte stuffing causes a different protocol length.

For the fixed frame protocol each LPR-1DHP data packet is filled up with zero bytes to a fixed length of bytes (i.e. 87 bytes) before the data packet is sent. Byte stuffing does not occur. The START and the END byte are still used but not clear anymore due to not applying byte stuffing. The fixed length of the data packets can be set on the web-interface of the LPR-1DHP unit.

If TCP/IP is used the transmitted data have already a checksum. Therefore the checksum in the protocol is not as important as for the serial interface.

8.3.1 Detailed description TCP Fixed-Frame Protocol

If a TCP fixed-frame protocol is used, a working TCP connection between the PC and the LPR unit has to be guaranteed. Depending on the configuration of the LPR protocol

converter either the connection to a port on the LPR has to be initialized from the PC or the LPR unit is establishing a connection to a PC.

If the connection is established, the PC has to read the data from the LPR in fixed data length (i.e. 89 bytes). The first byte is always the START-byte and the second byte is always the TYPE-byte. The relevance of the following data is depending on the data type. Because no byte stuffing occurs the content for a special data type is always constant. For example the measured velocity of the distance data is always written in data bytes 12-15

8.3.2 Detailed description UDP Fixed-Frame Protocol

If a UDP fixed frame protocol is used, the IP and the UDP port of the PC has to be configured in the LPR protocol inverter. The converter sends each data packet as a UDP packet of a fixed length (89 byte) to the PC. Compared to the TCP fixed frame option the UDP fixed frame does not verify if the data packed arrived. The content is the same as for the TCP fixed frame protocol.

8.4 Error messages

The distance data contains an error field which indicates the status of the message. The following errors can occur:
