Ethernet Base Controller, H2-EBC(100)(-F)
The Ethernet Base Controller module H2-EBC(100)(-F) provides a low-cost, high-performance
Ethernet link between a network master controller and an DirectLOGIC PLC I/O slave system.
Also, the H2-EBC100 supports the Modbus TCP/IP client/server protocol.
The Ethernet Base Controller (EBC) serves as an interface between the master control system
and the DL205/405 I/O modules. The control function is performed by the master controller,
not the EBC slave. The EBC occupies the CPU slot in the base and communicates across the
backplane to input and output modules. Various master controllers with EBC slaves are shown
in the diagram below.
The H2-EBC module supports industry standard 10BaseT Ethernet communications, the
H2-EBC100 module supports industry standard 10/100BaseT Ethernet communications and
the H2-EBC-F module supports 10BaseFL (fiber optic) Ethernet standards.
