In order that a SINAUT MD720-3 can actively establish a GPRS connection to the

OPC Server SINAUT MICRO SC, the OPC Server SINAUT MICRO SC must have

a fixed IP address. There are three ways of obtaining a fixed IP address:

Fix IP address

The server is connected to the GPRS network via a dedicated line. In this case it

has normally been assigned a fixed IP address by the network operator. (An IP

address consists of 4 numbers, separated by full stops, which can each have up to

three digits, e.g. 184.17.20.30).

The server can be accessed via the Internet and has been assigned a fixed IP

address by the Internet service provider (the address can be applied for from some

Internet service providers).

Fixed IP address via DynamicDNS provider

The server can be accessed via the Internet and is assigned dynamic IP addresses

but he is registered with a DynamicDNS provider (DNS = Domain Name Server) -

see Glossary. Thus, he has a fixed name (URL = Uniform Resource Locator) in

URL format.
