Gateway functionality

The Gateway functionality provides a framework that enables the use of OPC server and
client components, such as OPC Client for IEC 60870-5-101 and OPC Server for LON
LAG 1.4. This manual presents the principles that are common to the protocols available
at the moment as well as to those that will be applicable in the future. For protocol-specific
information , refer to the respective client and server user's manuals.

Normally, there is one OPC client per NCC connection. If you want to create several
NCC connections with the same protocol, use multiple instances.
COM600 consists of OPC Data Access (DA) server and client components. OPC Servers
are used mainly for master/client protocol stacks to provide access to the data in the
devices in the protocol. OPC Clients are used for slave/server protocol stacks to enable
external systems to access data available in the OPC Servers.
