■ Protection class IP20

■ 2 x end brackets BL20-WEW35/2-SW

■ 1 x end plate BL20-ABPL

■ LEDs for display of supply voltage, group

and bus errors

■ Multiprotocol gateway between the BL20

system and the Ethernet protocols Modbus

TCP, EtherNet/IP? and PROFINET (from

VN 03-00)

■ PROFINET supports fast start-up (FSU)

■ EtherNet/IP? supports QuickConnect

(QC)

■ Integrated switch 10/100 Mbps

■ Two RJ45 ports for fieldbus connection

■ Push-in terminals for connection of power

supply

Functional principle

BL20 gateways are the head component of

a BL20 station. They are designed to interface the modular fieldbus nodes to the higher level fieldbus (PROFIBUS-DP, DeviceNet,

CANopen, Ethernet).

All BL20 electronic modules communicate

over the internal module bus, the data of

which is transferred to the fieldbus via the

gateway, so that all I/O modules can be configured independently of the bus system.
