BL20 Philosophy The Basic Concept BL20 is a modular I/O system for use in industrial automation. It connects the sensors and actuators in the field with the higher-level master. BL20 offers modules for practically all applications: Digital input and output modules Analog input and output modules Technology modules (counters, RS232 interface...) A complete BL20 station counts as one station on the bus and therefore occupies one fieldbus address...
BL20 Components BL20 Components 2.2.1 Gateways The gateway connects the fieldbus to the I/O modules. It is responsible for handling the entire process data and generates diagnostic information for the higher-level master and the software tool I/O- ASSISTANT. ECO-Gateways The BL20-ECO gateways enlarge the product portfolio of BL20. They offer an excellent cost/ performance ratio.
BL20 Philosophy Gateways with Integrated Power Supply All standard gateways BL20-GWBR-××× as well as the BL20-gateways for DPV1 and Ethernet (BL20-GW- DPV1, BL20-GW-EN, BL20-GW-EN-IP, BL20-PG-EN and BL20-PG-EN-IP) offer an integrated power supply unit for feeding the gateway and the connected I/O modules. It is not necessary to supply each individual module with a separate voltage.
BL20 Components 2.2.2 Power Distribution Modules The power supply for gateways and I/O modules is fed to the power distribution modules; therefore, it is not necessary to supply each individual module with a separate voltage. Figure 2-3: Power distribu- tion module 2.2.3 Electronics Modules (Standard Product Line) The standard electronics modules contain the I/O-functions of the BL20 modules (power distribution...
BL20 Philosophy Figure 2-5: Electronics module in block design 2.2.4 ECO Electronics Modules New ECONOMY modules with a high signal density and exceptionally low channel price expand the BL20 I/O bus terminal system. Depending on type, up to 16 digital inputs and outputs can be connected on only 13 mm. This high connection density considerably reduces the mounting width required for typical applications.
BL20 Components 2.2.5 Base Modules The field wiring is connected to the base modules. These are constructed as terminals in block and slice designs and are available in the following variations with either tension clamp or screw connections: 2- /3-wire (2-channel), 4-wire (2-channel) and 4 x 2-/3-wire (4-channel). Figure 2-7: Base module with tension clamp...
BL20 Philosophy 2.2.6 End Plate An end plate on the right-hand side physically completes the BL20 station. An end bracket mounted into the end plate ensures that the BL20 station remains secure on the mounting rail even when subjected to vibration. Figure 2-10: End plate 2.2.7...

Short description of CANopen CANopen Note The following description of CANopen is an excerpt from the homepage of CiA (CAN in Automation), the international users’ and manufacturers’ organization for CAN. 3.1.1 General CANopen is an open, non-proprietary network protocol. It consists of a profile family, based on a communication profile and several device profiles.
CANopen The NMT message is mapped to a single CAN frame with a data length of 2 byte. Its identifier is 0. The first byte contains the command specifier and the second contains the Node-ID of the device that must perform the command (in the case of Node-ID 0 all nodes have to perform the command).
Short description of CANopen Special Function Objects CANopen also defines three specific protocols for synchronization, emergency indication, and time- stamp transmission. Synchronization object (Sync) The Sync Object is broadcast periodically by the Sync Producer. The time period between Sync messages is defined by the Communication Cycle Period, which may be reset by a configuration tool to the application devices during the boot-up process.
BL20 and CANopen BL20 and CANopen BL20 supports the following CANopen functions: SDO transfer, any length of information Emergency object Sync frame evaluation Event-driven PDOs Synchronous PDOs (clock-synchronous) Remote-requested PDO/polling D301108 1211 - BL20-ECO CANopen...

Guidelines for Station Planning Protecting the Service Interface on the Gateway During operation, the label protecting the service interface and the DIP-switches must remain closed due to EMC and ESD. Plugging and Pulling Electronics Modules BL20 enables the pulling and plugging of electronics modules without having to disconnect the field wiring.
Guidelines for Electrical Installation General Notes 7.1.1 General Cables should be grouped together, for example: signal cables, data cables, heavy current cables, power supply cables. Heavy current cables and signal or data cables should always be routed in separate cable ducts or bundles.
Station x Cable Types Turck offers a variety of cable types for fieldbus lines as premoulded or bulk cables. The ordering information for the available cable types can be found in the TURCK BL20 catalogs. D301108 1211 - BL20-ECO CANopen...
Guidelines for Electrical Installation Potential Relationships 7.2.1 General The potential relationship of a PROFIBUS-DP system realized with BL20 modules is characterized by the following: The system’s power supply to the gateway, I/O modules and the field level is connected to the gateway.
Electromagnetic Compatibility (EMC) Electromagnetic Compatibility (EMC) BL20 products comply in full with the requirements pertaining to EMC regulations. Nevertheless, an EMC plan should be made before installation. Hereby, all potential electromechanical sources of interference should be considered such as galvanic, inductive and capacitive couplings as well as radiation couplings.
Guidelines for Electrical Installation 7.3.5 Protection against high frequency interference signals Attention In order to comply with radiation limit values in accordance with EN 55 011/2 000, the supply lines for supplying the gateway with power are to be fed through a ferrite ring (PS416-ZBX- 405).
Electromagnetic Compatibility (EMC) 7.3.7 EMC Compliant Cabinet Installation Figure 7-4: EMC compliant cabinet installa- tion A Bonding straps Bonding straps connect inactive metal components, if it is not possible to create a large surface area contact. Use short bonding straps with large surface areas. B Mounting plates Mounting plates used to hold control components must have a large surface area contact with the cabinet housing.
Guidelines for Electrical Installation 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).
