X20BC00G3

Description:

• Fieldbus: EtherCAT

• Auto-configuration of I/O modules

• I/O configuration and firmware update via the fieldbus (FoE)

• Full support of the modular slice concept via CoE (CANopen over EtherCAT)

• Configurable I/O cycle (0.2 to 4 ms)

• Synchronization between the fieldbus and X2X Link

EtherCAT is an Ethernet-based fieldbus developed by Beckhoff. This protocol is suitable

for both hard and soft real-time requirements in automation technology. In addition to

a ring structure, which becomes logically necessary because of the summation frame

telegram used, the EtherCAT technology also physically supports topologies such as line,

tree, star (limited) and combinations of these topologies. B&R’s X20BC80G3 (expandable

bus controller module) and X20HB88G0 (standalone junction base module) are available

for implementing these topologies.

EtherCAT slave devices take the data designated for them from a telegram as it is passing

through the device. Input data is also added to the telegram as it is passing through.

The bus controller allows X2X Link I/O modules to be coupled to EtherCAT and operated on

any EtherCAT master system. A transition between IP20 and IP67 protection outside of the

control cabinet is possible by arranging X20. X67 or XV modules one after the other as

needed at distances up to 100 m.

Master systems without FoE (File access over EtherCAT) support require an appropriate

configuration tool to transfer the configuration (optional).

modules. Various bus and network systems can easily be integrated into

the X20 system through the use of communication modules.

The EtherCAT interface

From an Ethernet standpoint, the EtherCAT bus is simply a single large Ethernet station. This “station” re

ceives and transmits Ethernet telegrams. The station does not include an Ethernet controller with down

stream microprocessor, however, but rather a large number of EtherCAT slaves. These slaves process the

incoming telegrams during the cycle and extract the relevant payload data or add it and then forward the

telegram to the next EtherCAT slave. The last EtherCAT slave then returns the now fully processed telegram

so that it will be sent back to the master by the first slave as a kind of response telegram. This procedure

utilizes the fact that Ethernet deals separately with transfers in separate directions (Tx and Rx lines) and

operates in full-duplex mode.

The telegrams are processed in a continuous process. While the telegrams are already being sent on, de

layed by just a few bits, the slave recognizes certain commands for itself and executes them accordingly.

Processing takes place in the hardware and is therefore independent of the response times of the slave.

Each station has an addressable memory area of 64 kB, within which it is possible to read, write or write

and read simultaneously. Several EtherCAT commands can be embedded within an Ethernet telegram, each

of which addresses individual stations and/or memory areas.

Supported protocols and functions

Supported protocols:

• File access over EtherCAT (FoE object)

• Complete access (supported since firmware version 18)

° Enabled: Objects are read or written with all existing subindices.

° Disabled: Objects are only read or written with the specific subindex.

Additional supported functions:

• 32-bit “distributed clocks” function

Firmware

The module comes with preinstalled firmware. The firmware is part of the Automation Studio project. The

module is automatically brought up to this level.

A hardware upgrade must be performed to upgrade the firmware included in Automation Studio (see Help

“Project management – Workspace – Upgrades” in Automation Help).

Error codes

The module returns an error code if an error occurs. A complete list of all error codes in PDF format is avail

able in under item “Communication_Error” in section “Communication / Fieldbus systems / Support with

FDT/DTM / Diagnostic functions / Diagnostics on the runtime system / Master diagnostics” in Automation

Help.

Module description

The interface module is equipped with an EtherCAT interface. This allows the B&R system (I/O modules,

POWERLINK, etc.) to be connected to systems from other manufacturers and makes it possible to quickly

and easily transfer data in both directions.

The interface is equipped with 2 RJ45 connections. Both connections result in an integrated switch. This

makes it easy to implement daisy chain cabling.

Functions:

• EtherCAT slave

• Error monitoring

EtherCAT

EtherCAT is an Ethernet-based fieldbus developed by Beckhoff. This protocol is suitable for both hard and

soft real-time requirements in automation technology.

Error monitoring

The status of the module and fieldbus is monitored. An error code is returned if an error occurs.

The resulting measured values include the pure phase current; line-to-line voltage or phase

voltage; the effective, reactive and apparent power parts; the mains frequency; the power

factor and much more. In addition, peak values and energy meters are stored on the module

in nonvolatile memory. Depending on the configuration, it is also possible to use a digital

output as a pulse encoder for an external energy meter.

The synchronization unit doesn’t just take the phasing and phase voltage into consideration;

integrated intelligence also monitors the rate of change and other parameters, allowing them

to influence when the synchronization output is switched. It is also possible to monitor a

generator using a large number of additional conditions. A total of 4 voltage inputs provide

substantial overall flexibility.

Monitoring functions expand the features of the module. Dependent overcurrent monitoring is

included, which utilizes the thermal capacity of the motor/generator to allow short overloads

while still providing full protection. The dependent, delayed imbalanced load monitoring used

to protect three-phase generator and three-phase networks from imbalanced load can be

adapted to the characteristics of different generator types using parameters while taking their

special thermal time constants into account.

special features with a synchronization unit that is able to meet all demands.

The measurement unit’s 3 current inputs are suitable for both X: 1 A and X: 5 A current

transformers. Overcurrent resistance and the high resolution of the measurement unit

round off its features. For the voltage inputs, the value range can be configured between

480 VAC and 120 VAC.

The area of use includes 4-wire AC networks with a phase voltage up to 480 VAC and

3-wire systems, whereas L2 can be grounded (V-connection). The module can also handle

Aron measuring circuits.
