2 Tasks of the LAN Gateway
2.1 Field of application
The LAN Gateway is used to connect an E•LDS system to a networ
k (LAN) for the purpose of local operation on
site (e.g. for the market manager), as well as for remote supervision and configuration. This TCP/IP-based form
of communication represents an alternative to transmission via serial interface, modem or CAN bus-PC adapter,
and it so helps the development towards a network-based communication solution:
It is possible to access the E•LDS system via a PC in the same network (local LAN) by means of the LDSWin
software. In addition, a connection can also be made via
the LAN Gateway to an E•LDS system outside the
network boundaries. To do this, existing Internet connections can be used to access an E•LDS system from a
PC at another location.
Violation of data protection!
The LAN gateway is not equipped with any security
mechanisms for the encryption of communication via the LAN interface. For this
reason connections should only be established in secure networks. For
communication via public or insecure networks additional security components (e.g.
VPN router etc.) should be employed.
Under no circumstances should the LAN gateway be connected
directly
with the
Internet.
CAN bus address conflict!
The parallel operation of a LAN gateway and a PC-CAN
bus adapter is only possible when the CAN bus address for the LAN gateway is
configured to 127 (see section 4.5.3).
