    ID is determined for each device by the IEEE (Institute of Electrical and Electronics Engineers, New York). The first 3 bytes of the MAC-ID contain a manufacturer identifier (Turck: 00:07:46:××:××:××). The last 3 bytes can be chosen freely by the manufacturer for each device and contain a definite serial number.

  • Page 25: Checking The Communication Via "Ping-Signals

    Ethernet Modbus TCP In Ethernet TCP/IP networks, Modbus TCP uses the Transport Control Protocol (TCP) for the transmission of the Modbus application protocol. All parameters and data are embedded in the user data of the TCP-telegram using the encapsulation protocol: the client generates a special header (MBAP = Modbus Application Header), which enables the server to clearly interpret the received Modbus-parameters and -commands.

  • Page 26: Arp (Address Resolution Protocol)

    System Description 3.1.6 ARP (Address Resolution Protocol) In each TCP/IP-capable computer, ARP serves to clearly assign the worldwide unique hardware addresses (MAC-IDs) to the single IP addresses of the network nodes via internal tables. Using ARP in the DOS-prompt, every node in a network can be clearly identified via its MAC-ID. Write a ping command for the respective station/ IP address: (example: "x:\\ping 192.168.1.100").

  • Page 37: Address Setting

    Technical Features Address Setting The addressing of the BL20 Modbus TCP gateway can be realized via different modes: rotary mode (manual addressing via rotary coding-switches) PGM mode (manual addressing via software) BootP mode, DHCP mode (automatic addressing via BootP/DHCP-server at the boot-up of the gateway).

  • Page 38: Default Setting Of The Gateway

    Address Setting 4.6.2 Default setting of the gateway The gateway’s default-settings are the following: IP address 192.168.1.254 subnet mask 255.255.255.000 default gateway 192.168.1.001 Note The gateway can be reset to these default settings by the user at any time. To reset the gateway, please set the three coding-switches at the gateway to "000" followed by a power-on reset.

  • Page 40: Address Setting Via Dhcp-Mode

    Address Setting Note The IP address as well as the default subnet mask assigned to the gateway by the BootP-server are stored in the gateway’s non-volatile memory. If the gateway is subsequently switched to rotary- or PGM-mode, the settings carried out via BootP (IP address, subnet mask, etc.) will be taken from the module’s EEPROM.

    Shielding of cables Shielding of cables Shielding is used to prevent interference from voltages and the radiation of interference fields by cables. Therefore, use only shielded cables with shielding braids made from good conducting materials (copper or aluminum) with a minimum degree of coverage of 80 %. The cable shield should always be connected to both sides of the respective reference potential (if no exception is made, for example, such as high-resistant, symmetrical, analog signal cables).

    Guidelines for Electrical Installation Potential Compensation Potential differences can occur between installation components that are in separate areas and these are fed by different supplies, have double-sided conductor shields which are grounded on different installation components. A potential-compensation cable must be routed to the potential compensation. Danger Never use the shield as a potential compensation.

    11 Glossary Acknowledge Acknowledgment of a signal received. Active metal component Conductor or conducting component that is electrically live during operation. Address Identification number of, e.g. a memory position, a system or a module within a network. Addressing Allocation or setting of an address, e. g. for a module in a network. Used to definitely allocate the hardware addresses (MAC-IDs) assigned worldwide to the IP addresses of the network clients via internal tables.
  • Page 157 Glossary Bus system All units which communicate with one another via a bus. Capacitive coupling Electrical capacitive couplings occur between cables with different potentials. Typical sources of interference are, for example, parallel-routed signal cables, contactors and electrostatic discharges. Check-back interface The check-back interface is the interface from the counter module to the internal module bus.
  • Page 158 German acronym for European Standard. Electrostatic Discharge. Field power supply Voltage supply for devices in the field as well as the signal voltage. Fieldbus Data network on sensor/actuator level. A fieldbus connects the equipment on the field level. Characteristics of a fieldbus are a high transmission security and real-time behavior.
  • Page 159 Glossary Inactive metal components Conductive components that cannot be touched and are electrically isolated from active metal components by insulation, but can adopt voltage in the event of a fault. Inductive coupling Magnetic inductive couplings occur between two cables through which an electrical current is flowing. The magnetic effect caused by the electrical currents induces an interference voltage.
  • Page 160 Modbus TCP The Modbus protocol is part of the TCP/IP protocol. The communication is realized via function codes, which are implemented into the data telegram. Modbus TCP uses the Transport Control Protocol (TCP) for the transmission of the Modbus user protocol in Ethernet-TCP-IP networks.
  • Page 161 Glossary Root-connecting Creating a new potential group using a power distribution module. This allows sensors and loads to be supplied individually. RS 485 Serial interface in accordance with EIA standards, for fast data transmission via multiple transmitters. Serial Type of information transmission, by which data is transmitted bit by bit via a cable. Setting parameters Setting parameters of individual stations on the bus and their modules in the configuration software of the master.
