10.2.2 OPC UA address space
OPC UA provides different services on the LioN-X devices with which a client
can navigate through the hierarchy of the address space and read or write
variables. In addition, the client can monitor up to 10 attributes from the
address space for value changes.
A connection to an OPC UA server is established via the endpoint URL:
opc.tcp://[ip-address]:[port]
Various device data such as MAC address, device settings, diagnostics or
status information can be read via
Identity objects
,
Config objects
,
Status
objects
and
Process objects
.
Command objects
can be read and written. This makes it possible, for
example, to transfer new network parameters to the device, to use Force
Mode or to reset the entire device to its factory settings.
The following figures illustrate the OPC UA address space of the LioN-X
devices. The objects and information displayed depend on the device variant
used.
