Beckhoff‚â€™s BC9120, BC9020, and BC9050 Ethernet PLCs for the Bus Terminal I/O system 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. They all implement the Modbus TCP, ADS/TCP, ADS/UDP, BootP, DHCP, SNTP, and SMTP protocols.
The BC9050 Bus Terminal Controller is cost-effective and saves space. The BC9020 and BC9120 models have 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 traditionalstar topology.
