For OPC UA: Denotes the OPC UA path for the tag to subscribe data.
The syntax for OPC UA path is:
opc.tcp://nodename:port/progid//ItemId;namespace=name
For example:
opc.tcp://fi8-
main:4841///Variable.SYS_CPU0_Time;UaNamespace=http://fi.abb.c
om/Vtrin
The progid value is just some name that can be used if multiple
connections to the same OPC UA server is wanted to be configured. If
the ProgId is present, the SID name for the connection is
nodename_port_progid. If ProgId is not present, the SID name is just
nodename_port. (The SID name is just an identifying name for the
server connection in the RTDB OPC client. The SID name is present in
the diagnostic messages, and also in the name of the Item Report file
("EcOpcClient-ItemReport-sid.txt"). The DaPath has also space for a
class id name after the progid. The class id should be left as
empty.The namespace definition can be omitted if a default has been
defined in SimpleConfig setting AppName/SID_sid as
"NameSpace=name".
For example:
insert into SimpleConfig(SectionName,KeyName,StrValue)
values('RTDB-EcOpcClient', 'SID_fi8-main_4841',
'UaNamespace=http://fi.abb.com/Vtrin')
