Functionality
The Hilscher netHOST is a communication device that connects a TCP/IP
network to a fieldbus or Real-Time Ethernet (RTE) network. The netHOST
device has a compact housing and is suited for DIN rail mounting according
to DIN EN 60715.
The netHOST device allows you to access data of a fieldbus or Real-Time
Ethernet network from your PC, terminal or other host system via TCP/IP.
Thus, the device serves as a gateway, respectively programming interface
between your PC/terminal/host system and the fieldbus or RTE network.
Once configured, the netHOST device controls the secondary network on
its own.
An appropriate application program establishes the TCP/IP connection to
the device and accesses the data of the fieldbus/RTE network.
Access to the netHOST device takes place according to the “Ethernet
Marshalling” procedures, by which locally generated service requests of an
initiator (i. e. the host application) are being transmitted to a receiver (i. e.
the netHOST device) by an appropriate method (i. e. coded/decoded in
Ethernet telegrams). The service requests are then called and executed
“remotely” on the netHOST device.
The host system can be based on a Windows operating system, but is,
however, not restricted to Windows only. For Windows developers, the
netHOST Solutions DVD provides the code with the Ethernet Marshalling
function both as C++ source code and as Windows DLL
(netXTransport.dll). For developers of embedded systems, the DVD
provides a C source code which is independent from any specific type of
operating system.
Important:
The Ethernet LAN connection to the netHOST device is not
protected by password or encryption. Protection against
unauthorized access by external networks has to be ensured by
using adequate measures !
