Small PLCs are designed for Ethernet TCP/IP control.

Press Release Summary:

Featuring direct connection to Beckhoff I/O terminals, models BC9120, BC9020, and BC9050 can be operated as stand-alone PLCs or decentralized intelligence in Ethernet network. Each has implemented Modbus TCP, ADS/TCP, ADS/UDP, BootP, DHCP, SNTP, and SMTP protocols. While BC9050 extends Beckhoff Bus Terminal system in space-saving housing, BC9020 and BC9120 offer additional program and data memory. Also, BC9120 has 2 Ethernet ports that act as 2-channel switch.

Beckhoff Automation Adds New Models to Comprehensive Ethernet PLC Family

Enhanced range of small PLCs for Ethernet TCP/IP

MINNEAPOLIS, June 12, 2008 - In order to provide a leading array of small, flexible PLCs, Beckhoff Automation has announced new models in its Ethernet TCP/IP controller family. Beckhoff's BC9000 and BX9000 series Ethernet PLCs for the Bus Terminal I/O system are now complemented with the new BC9120, BC9020 and BC9050 variants.

These new controllers range in features and price, offering a scalable solution to help balance performance with cost. The BC controllers include a direct connection to Beckhoff I/O terminals and can be operated as a stand-alone PLC or as decentralized intelligence in an Ethernet network. All Beckhoff Ethernet controllers have implemented the Modbus TCP, ADS/TCP, ADS/UDP, BootP, DHCP, SNTP and SMTP protocols.

New Beckhoff PLCs in detail

The new "Compact" BC9050 Bus Terminal Controller extends the Beckhoff Bus Terminal system with a cost-optimized variant in a space-saving housing. As a step up in performance, the new BC9020 and BC9120 models offer more program and data memory than the BC9050. The BC9120 has two Ethernet ports that act as a 2-channel switch. The I/O stations can be configured with a line topology instead of the traditional star topology.

Beckhoff has built a strong reputation on PC-based control, but the company also has a scalable PLC product portfolio with devices that cost-effectively provide powerful control functionality. Since the introduction of Ethernet as a communications standard for automation technology, Beckhoff has continuously enhanced its product range to be optimized for Industrial Ethernet. In addition to Ethernet TCP/IP, Beckhoff also offers PLCs for several major fieldbus networks including EtherCAT, DeviceNet, PROFIBUS, SERCOS, CANopen, Lightbus and Interbus.

Beckhoff Automation provides advanced, open automation products based upon proven technologies so that customers can implement high performance control systems faster and at a lower overall cost than traditional PLC and motion control systems. Beckhoff's "New Automation Technology" product range includes PC based control, industrial PCs, automation controllers, operator interface, I/O, servo drives and motors. With representation in more than 60 countries, Beckhoff is well positioned to provide global sales and service to its customers. Sales and service are handled directly, with no intermediaries involved to provide faster response and improved communications.
