The BK1150 EtherCAT Coupler is the link between the EtherCAT protocol at fieldbus level and the Bus Terminals. The coupler converts the passing telegrams from Ethernet 100BASE-TX to the internal, fieldbus-independent terminal bus.
The KL1154 digital input terminal acquires the binary 24 V DC control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The Bus Terminal contains four channels that indicate its signal state by means of light emitting diodes.
The CX9020 is a compact, DIN rail-mountable Ethernet control system with 1 GHz ARM Cortex™-A8 CPU. The connection for the Beckhoff I/O systems is directly integrated into the CPU module.
