6. OPC UA Server Connection
The TigoMaster 2TH contains an OPC UA server, to which an OPC UA client can connect. The client can
then access the following parameters:
• TigoMaster 2TH identification parameters
• Sensor/Actuator identification parameters
The OPC UA client connects via the following URL: opc.tcp://IP address:4840, wherein IP address is
the IP address of the TigoMaster 2TH.
The OPC UA client can access parameters anonymously (read only) or with a username and password
(read and write). The username and password are set by means of TigoEngine and the Integrated Web
Server.
6.1. TigoMaster 2TH Identification
The TigoMaster 2TH includes nodes for its identification. For example, the OPC UA client can read the
version of the TigoMaster 2TH firmware in the SoftwareRevision node (node path: Root > Objects >
DeviceSet > [Device Name] > ParameterSet > SoftwareRevision). Figure 24 shows the path to the
nodes, and Table 28 details the nodes.
