The Ethernet bus coupler opens a local bus for up to 16 devices. Additional functions: 10 Mbps and
100 Mbps, auto negotiation, auto crossover, 8 digital inputs, channel-specific diagnostics, short-
circuit and overload protection, M12 fast connection technology.
Product Description
The Fieldline Modular FLM BK ETH M12 DI8 M12 bus coupler with 8 digital inputs couples a Fieldline Modular local bus station to an
Ethernet network and is also used for measuring digital signals. The bus coupler consists of two Ethernet connections that are designed
as D-coded M12 sockets. Additional Ethernet devices can be connected due to the integrated, manageable 3-port switch to implement
a line structure. The transmission speeds are 10 Mbps and 100 Mbps and are automatically selected by the device (autonegotiation).
The interfaces can automatically interchange the receive and transmit cables (autocrossover). Following network protocols are
supported by the FLM BK ETH M12 DI8 M12 bus coupler:– Modbus/TCP– Modbus/UDP– DDI (Device Driver Interface)The Ethernet
bus coupler provides a powerful local bus as lower-level bus. The total length of the local bus is 20 m and it can connect up to 16 I/O
units. Selectable transmission speeds in the range 500 kBaud to 2 Mbaud allow for flexible adaptation to the application and also permit
savings on warehousing costs. The local bus connection is provided by 5-pos. B-coded M12 connectors. The four double-occupied
sensor slots can be assigned through 5-pos. A-coded M12 connectors with sensors in 2, 3 or 4 conductor technology respectively.The
sensor supply is short-circuit and overload-protected and thus guarantees a high plant availability. The diagnosis and status indicators
for voltage supply, network and local bus operation with the corresponding monitoring functions reduce bus downtime and provide
support if service becomes necessary.The high-performance SPEEDCON technology used allows connection times to be reduced by up
to 90 %. The classic M12 connections can continued to be used with full compatibility. 
