Ethernet Base Controller, H2-EBC(100)(-F)
1
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.
2
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
3
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
4
slaves are shown in the diagram below.
