scalable, Modbus TCP, ADS/TCP, ADS/UDP, BootP, DHCP, SNTP and SMTP

The existing range of BC9000 and BX9000 Ethernet controllers for the Bus Terminal I/O system is complemented by the BC9120, BC9020 and BC9050 versions. The controllers differ in terms of technical features and price. They can be operated as stand-alone PLC or as decentralised intelligence in an Ethernet network. All Ethernet controllers have implemented the Modbus TCP, ADS/TCP, ADS/UDP, BootP, DHCP, SNTP and SMTP protocols. The compact BC9050 Bus Terminal Controller extends the system by a cost-optimised variant in a compact housing. The BC9020 and BC9120 models offer more program and data memory than the BC9050. The BC9120 has two Ethernet ports that act as a two-channel switch. The I/O stations can thus be configured with a line topology, instead of the classic star topology. The system offers more than 250 types of I/O terminals.
