TCP Network Adapter
EPXMBE001/EPXMBE101
The EPXMBE001 network adapter is a Modbus TCP participant developed according to IEC
61158. The network adapter is the head module for the RSTi-EP communication bus, to
which up to 64 active RSTi-EP modules can be connected. The Modbus TCP network adapter
has two Ethernet ports and an integrated switch supporting a line network structure.
The EPXMBE101 network adapter is a variant of EPXMBE001 network adaptor, which
supports “Modbus Dual LAN mode” of operation. In this mode of operation, both the
Ethernet ports communicate with two separate networks. For this purpose, the EPXMBE101
has two MAC addresses and two IP addresses that can be defined separately over two
different LAN networks. The “Modbus Dual LAN mode” is suitable to communicate with two
synchronized control units simultaneously. Thereby both the control units have the
complete read and write access. If the “Modbus Dual LAN mode” is disabled in EPXMBE101,
the network adaptor functions as EPXMBE001 with a single LAN network.
The network adapter can be accessed with a system-independent web server application via
the USB service interface or the Ethernet. Thus, all information, such as diagnostics, status
values and parameters, can be read and all connectedmodules can be simulated or forced.
The station's main power supply is integrated in the network adapter. Power is supplied via
two 4-pole connectors, separated into the input and output current paths.
