BL20-philosophy

2.1 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 in any given fieldbus structure. A BL20 station consists of a gateway, power distribution modules and I/O modules.

The connection to the relevant fieldbus is made via the bus-specific gateway, which is responsible for the communication between the BL20 station and the other fieldbus stations.

The communication within the BL20 station between the gateway and the individual BL20 modules is regulated via an internal module bus.

2.1.1 Flexibility

All BL20 stations can be planned to accommodate the exact number of channels to suit your needs, because the modules are available with different numbers of channels in block and slice design.

A BL20 station can contain modules in any combination, which means it is possible to adapt the system to practically all applications in automated industry.

2.1.2 Compactness

The slim design of the BL20 modules (standard gateway 50.4 mm / 1.98 inch, ECO gateway 34 mm/ 1.34 inch, standard slice 12.6 mm / 0.49 inch, ECO slice 13 mm / 0.51 inch and block 100.8 mm / 3.97 inch) and their low overall height favor the installation of this system in confined spaces.

2.1.3 Easy to handle

All BL20 modules of the standard line, with the exception of the gateway, consist of a base module and an electronics module. The gateway and the base modules are snapped onto a mounting rail. The electronics modules are plugged onto the appropriate base modules.

The base modules of the standard line are designed as terminal blocks. The wiring is secured by tension clamp or screw connection.

The electronics modules 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.

Note

The gateway is the only fieldbus-dependent module on a BL20 station. All other BL20 modules are not dependent on the fieldbus used.

The ECO electronics modules combine base module and electronics module in one housing. All BL20ECO modules can be used with the standard products with tension clamp connection technology.

2.2 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/OASSISTANT.

ECO-gateways

The BL20-ECO gateways enlarge the product portfolio of BL20. They offer an excellent cost/ performance ratio.

Further advantages of the gateways in the ECO-housing:



At the moment available for PROFIBUS-DP, DeviceNet™, CANopen, Modbus TCP, EtherNet/IP™, EtherCAT® and PROFINET®

 Low required space: width 34 mm/ 1.34 inch minimal space requirements

 Can be combined with all existing standard modules (with tension clamp connection technology)

and ECO modules

Figure 2-1: Gateway BL20-E-GW-EN

 Simple wiring with "Push-in" tension clamp terminals, via DeviceNet™-Open Style Connector or via

Ethernet RJ45-connectors

 Automatic bit rate detection for PROFIBUS-DP and DeviceNet™

 Setting of fieldbus address and bus terminating resistor (PROFIBUS-DP, DeviceNet™, CANopen) via

DIP-switches

 Service interface for commissioning with I/O-ASSISTANT 3 (FDT/DTM), without PLC)

BL20-philosophy

Gateways with integrated power supply

All standard gateways BL20-GWBR-××× as well as the BL20-gateways for DPV1 and Ethernet (BL20-GWDPV1, 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.

Gateways without integrated power supply

Note

The gateways without integrated power supply unit need an additional power supply module (bus refreshing module) which feeds the gateway an the connected I/O modules.

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 2-2: Power distribution module

D301173 0713 - BL20- Ethernet multiprotocol gateway 2-4

Page 18

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.

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.

All advantages at a glance:



Space saving thanks to 16 channels on 13 mm/ 0.51 inch width

 Cost saving thanks to electronics with integrated connection level

 High signal density

 Tool-less connection via "push-in" spring-type terminal technology for simple and fast mounting

 Flexibility in combining them with standard I/O-modules in tension clamp technology, the

standard- and the ECO-gateways.

 Simple assembly reduces error sources

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).

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 End bracket

A second end bracket to the left of the gateway is necessary, as well as the one mounted into the end plate to secure the station.

Figure 2-9: End bracket

Note

The end plate and two end brackets are delivered with the gateway.

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.

2.2.9 Marking material

 Labels: for labeling BL20 electronics modules.

 Markers: for colored identification of connection levels of BL20 base modules.

 Dekafix connector markers: for numbering the mounting slots on BL20 base modules.

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).

Attention

After every change of the address-mode, a voltage reset must be carried done.

DHCP supports three mechanisms for IP address allocation:



In "automatic allocation", the DHCP-server assigns a permanent IP address to a client.

 In "dynamic allocation", DHCP assigns an IP address to a client for a limited period of time. After this

time, or until the client explicitly relinquishes the address, the address can be re-assigned.

 In "manual allocation", a client's IP address is assigned by the network administrator, and DHCP is

used simply to convey the assigned address to the client.

PROFINET®

Please assure, that in PROFINET® -applications, the address assigned via a BootP-server corresponds to the address, which is assigned in the configuration tool.

The device sends DHCP-requests until a IP-address is assigned (DHCP-server, PROFINET®-controller).

The assigned IP-address is stored to the device and the DCHP-client is stopped.

Even after a restart of the device, the device sends no further DHCP-requests.

PROFINET®

This mode assures a PROFINET®-compliant operation of the modules.

Note

If a DHCP-server is used within the network, problems may occur during IP-assignment.

In this case, both, the DHCP-server as well as the PROFINET®-controller (via DCP), try an IPaddress-assignment.

Switching from OFF to ON starts the storage of the Current Configuration as the Required Configuration (Reference configuration).

Procedure:

Switching the DIP-switch "CFG" from OFF to ON

 Starting of storage process

 LED IOs flashes green (1 Hz)

 LED IOs shortly lits up orange

 storage process active

 set back the DIP-switch from ON to OFF

 storage process terminated successfully, if the LEDs IOs and GW are constant green.

Note

If the DIP-switch is not set back, the gateway will continuously restart the storage process. Only setting the switch back from ON to OFF will terminate this process.

Implementation of EtherNet/IP™

4.1 The EtherNet/IP™ Communications Profile

TECHNICAL BASICS

EtherNet/IP™ is based on a connection-oriented communication model. This means that it is only possible to exchange data via specified connections assigned to the devices. Communication between the nodes in the EtherNet/IP™ network can be carried out either via I/O Messages or Explicit Messages.

I/O Messages

I/O Messages serve to exchange high priority process and application data over the network. Communication between the slaves in the EtherNet/IP™ network is carried out according to the Server/Client Model, which means a producing application transmits data to another or a number of consuming applications. It is quite possible that information is passed to a number of Application Objects in a single device.

Explicit Messages

Explicit Messages are used to transmit low-priority configuration data, general management data or diagnostic data between two specific devices. This is a point-to-point connection in a Server/Client System that requires a request from a client always to be confirmed by a response from the server. – Message Router Request

Consists of a service code, path size value, a message router path and service data. An EPATH is used in the message router path to indicate the target object.

– Message Router Response

Consists of a service field with the most significant bit set. This is an echo of the service code in the request message with the most significant bit set. A reserved byte follows the service code, which is followed by the General Status code.

The EtherNet/IP™ Communications Profile

4.1.1 Communications Profile for BL20

BL20 behaves as an EtherNet/IP™ Server in the network; the scanner of the higher-level controller operates as a EtherNet/IP™ Client.

The following EtherNet/IP™ communications types are supported:



Unicast

 Multicast

 Cyclic Connection

 Unconnected (UCMM) Explicit Messaging

 Connected Explicit Messaging

TECHNICAL BASICS

Unicast

A point-to-point connection that exists between two nodes only.

Multicast

A packet with a special destination address, which multiple nodes on the network may be willing to receive.

COS I/O Connection

COS (Change Of State) I/O Connections establish event-controlled connections. This means that the EtherNet/IP™ devices generate messages as soon as a change of status occurs.

Cyclic I/O Connection

Messages are triggered time-controlled in Cyclic I/O connections by means of a time generator.

UCMM

The EtherNet/IP™ gateway offers the option of establishing explicit messaging via the UCMM port (Unconnected Message Manager Port). UCMM-based explicit messaging is normally used for random, non-periodic requests. It is not recommended for frequent messaging because the UCMM input queue in a product is typically limited to just a few messages. Once this limit is reached, subsequent requests are ignored and must be retried.

Connected Explicit Messaging

CIP is a connection-based system. For most communications between nodes, a connection is used. A connection is a path or a virtual circuit between two or more end points in a system. The purpose is to transfer data in the most efficient manner possible. The Connection ID is a number that is associated with a communication relationship. Receiving nodes decode this key to know whether they must accept the data or not.

Implementation of EtherNet/IP™

4.2 Device Level Ring (DLR)

The BL20-E-GW-EN (FW-Version  V 3.2.8.0) supports DLR.

TECHNICAL BASICS

The Device Level Ring (DLR)-redundancy protocol is used to increase the stability of EtherNet/IP™ networks.

DLR-capable products provide an integrated switch and can thus be integrated into a ring topology. The DLR-protocol is used to recognize a ring fault. In case of an interruption of the data line, data are sent through an alternative network section, so that the network can be reconfigured as soon as possible. DLR-capable network nodes are provided with extended diagnostic functions which enable the devices to localize errors and thus decrease the time for error search and maintenance.

Diagnostic messages via the process data

4.3 Diagnostic messages via the process data

Besides the evaluation of diagnostic data via Explicit Messages, BL20 with EtherNet/IP™ offers the possibility of mapping diagnostic data into the process data (see also the stations‘ process data mappings (page 4-11 ff.).

2 different forms of diagnostic data handling are provided:



summarized diagnostics

 Scheduled Diagnostics

4.3.1 Summarized Diagnostics

The summarized diagnostic data mode will send back 1 bit for each slice within the station.

This bit will be "0" if there are no diagnostic flags set on the slice. If there are any diagnostic events on the device, the bit will be set to "1".

The diagnostic bits are placed at the end of the input data. The diagnostic data start WORD aligned (see

page 4-11).

Bit „I/O Diag Warn“

0 = OK, no diagnostics present

at least one module sends diagnostics (acc. to VSC 100, Gateway Class, Attr. 116, page 4-20)

4.3.2 Scheduled Diagnostics

If scheduled diagnostics is activated (Process Data Class (VSC102, 66h) (page 4-23)), the manufacturer specific diagnostic bits are mapped into the station's process data(page 4-5 ff.).

The scheduled diagnostic data is placed at the end of the input data and after the summarized diagnostic data (see page 4-11).

The scheduled diagnostic data is a time sliced module related data block, which holds diagnostic data of all modules with active diagnostics using a round robin mechanism.

This diagnostic "window" visualizes a specific module diagnostic data for approx. 125 ms and changes over to the next active diagnostics afterwards. This is done automatically by the gateway.
