Page 15: The Basic Concept
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 ...
Page 16: Bl20 Components
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.
Page 17: Power Distribution Modules
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-GW-EN-PN, 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.
Page 18: Electronics Modules (Standard Product Line)
BL20 components 2.2.3 Electronics modules (standard product line) The standard electronics modules contain the I/O-functions of the BL20 modules (power distribution modules, digital and analog input/output modules, and technology modules). They are plugged onto the base modules and are not directly connected to the wiring and can be plugged or pulled when the station is being commissioned or for maintenance purposes, without having to disconnect the field wiring from the base modules.
Page 19: Eco Electronics Modules
BL20-philosophy 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.
Page 20: Base Modules
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 2-5: Base module with tension...
Page 21: End Plate
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 2-8: End plate 2.2.7...
Page 22: Jumpers
BL20 components 2.2.8 Jumpers Jumpers (QVRs) are used to bridge a connection level of a 4-wire base module. They can be used to connect potentials in relay modules (bridging the relay roots); thus considerably reducing the amount of wiring. Figure 2-10: Jumpers 2.2.9 Marking material...
Page 23: Shield Connection Gateway
BL20-philosophy 2.2.10 Shield connection gateway If the gateway is wired directly to the fieldbus, it is possible to shield the connection using a special gateway-shielding connection attachment (BS3511/KLBUE4-31.5).

Implementation of Modbus TCP Common Modbus description Note The following description of the Modbus protocol is taken from the Modbus Application Protocol Specification V1.1 of Modbus-IDA. Modbus is an application layer messaging protocol, positioned at level 7 of the OSI model, that provides client/server communication between devices connected on different types of buses or networks.
Page 134: Protocol Description
Common Modbus description 6.1.1 Protocol description The Modbus protocol defines a simple protocol data unit (PDU) independent of the underlying communication layers. The mapping of Modbus protocol on specific buses or network can introduce some additional fields on the application data unit (ADU). Figure 6-2: Modbus tele- gram acc.

Diagnosis in PROFINET® Diagnosis in PROFINET® In PROFINET®, critical events (diagnostic messages) are reported acyclically as alarms. In addition to information as slot-number, subslot-number, channel type etc., the diagnostic telegrams contain error codes which define the diagnostic event more precisely. The error codes are interpreted by the PLC-software or respective function block, so that the diagnostic messages are normally displayed as plain text.

Page 229: Module Arrangement
Guidelines for station planning 10.1 Module arrangement 10.1.1 Random module arrangement The arrangement of the I/O-modules within a BL20 station can basically be chosen at will. Nevertheless, it can be useful with some applications to group certain modules together. Note A mixed usage of gateways of the BL20 ECO and the BL20 standard product line and I/O modules of both product lines (base modules with tension clamp terminals) is possible without any problems.
Page 230: Maximum System Extension
Module arrangement 10.1.3 Maximum system extension The maximum number of modules connected to the gateway BL20-E-GW-EN depends on the following:  The station extension may not exceed the maximum number of 32 modules.  Die maximum number of 192 communications bytes, which are transferred via the module bus from the gateway to the modules may not be exceeded (see below Table 10-1: Communication bytes and nominal current consumption of the...

Page 234: Creating Potential Groups
Power supply 10.2.3 Creating potential groups Power Feeding modules can be used to create potential groups. The potential isolation of potential groups to the left of the respective power distribution modules is provided by the base modules. Note The system can be supplied with power independent of the potential group formation. When using a digital input module for 120/230 V AC, it should be ensured that a potential group is created in conjunction with the Power Feeding module BL20-PF-120/230VAC-D.
Page 235 Guidelines for station planning Warning It is permitted to load the C-rail with a maximum of 24 V. Not 230 V! The C-rail can be used as required by the application, for example, as a protective earth (PE). In this case, the PE connection of each power distribution module must be connected to the mounting rail via an additional PE terminal, which is available as an accessory.

Page 241: General Notes
Guidelines for Electrical Installation 11.1 General notes 11.1.1 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.

Page 243: Potential Relationships
Guidelines for Electrical Installation 11.2 Potential relationships 11.2.1 General The potential relationship of a Ethernet system realized with BL20 modules is characterized by the following:  The system supply of gateway and I/O-modules as well as the field supply are realized via one power feed at the gateway.
Page 244: Electromagnetic Compatibility
Electromagnetic compatibility(EMC 11.3 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. 11.3.1 Ensuring electromagnetic compatibility The EMC of BL20 modules is guaranteed when the following basic rules are adhered to: ...

Page 246: Shielding Of Cables
Shielding of cables 11.4 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).
Page 247: Potential Compensation
Guidelines for Electrical Installation 11.5 Potential compensation Potential differences can occur between installation components that are in separate areas if 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. Warning Never use the shield as a potential compensation.
