1.2 isNet Lite
The Ethernet module isNet Lite is the head module of every isNet
Line gateway solution. In combination with any of the fieldbus
expansion modules its purpose is to exchange process data between
field devices and Ethernet based PLCs. Additionally it allows engi-
neering stations to access field device parameters for configuration
purposes, diagnosis and asset management.
The isNet Lite is equipped with a RJ45 socket for an Ethernet cable,
a side connector for the fieldbus expansion modules and a 24V DC
connector for power supply. Incoming power is also forwarded to
the side connector to supply all connected fieldbus expansion mod-
ules.
The firmware of the isNet Lite implements Ethernet based fieldbus
protocols for a direct communication link to a PLC. The gateway can
be used as a Profinet device or as a Modbus-TCP server. For access to
HART field devices the HART over IP protocol is implemented too.
To provide parameter access from a PC based solution, a Communi-
cation DTM is available, which allows to integrate the isNet gateway
into any FDT based application such as PACTware, Fieldcare or Asset
Vision Basic. Also an OPC server is available for data access from any
OPC client application. For further customization of the device, a
driver interface allows integration into customer specific applica-
tions.
The isNet Lite can be controlled and configured by using a web in-
terface which allows diagnosis and maintenance of the main module
and its connected expansion modules (see chapter 3 “Web Interface”
on page 39)
