opcua-adapter is an MTConnect adapter process to collect data from OPC UA servers and provide the stream updates for MTConnect Agent according to the requirements of MTConnect specification.
Usage:
opcua-adapter [config file - default is opcua-adapter.cfg]
# This configuration is for MetaAgent opcua-adapter
#
# OPC UA Server connection info
#
OpcUAServer:
name: OPCUA
# url: <opcua server's url>
url: opc.tcp://milo.digitalpetri.com:62541/milo
#
# applicationUri: <application name, for some OPC UA server, they may require it to match the client's certificate and/or the server's application name>
# default is urn:open62541.server.application
#
# namespaceFilter: <comma separated list of node's id using regex matching. stream data only from this node or below>
namespaceFilter: ns=2;s=File.*, \ # top nodes allows regex
ns=2;s=Dynamic/RandomDouble, \ # any individual node and their children
ns=2;s=Dynamic/RandomFloat, \
ns=2;s=Dynamic/RandomInt32, \
ns=2;s=CTT/Static/DA Profile/Analog Type
#
# sampleInterval: <the fastest rate at which OPC UA server's monitored items should be accessed and evaluated (ms)>
# default is 0, indicates that it should use the fastest practical rate
#
# Additional optional connection info
# cert: <location of the certificate file. Format: DER>
# key: <location of the key file. Format: PEM>
# user: <user's id>
# password: <user's password>
#
# certificateCheck: [true, false]
# default is false
#
# messageSecurityMode: [None, sign, sign&encrypt]
# securityPolicy: [None, Basic128Rsa15, Basic256, Basic256Sha256, Aes128_Sha256_RsaOaep]
#
# messageSecurityMode and SecurityPolicy are only required if the server does not provide discovery service
#

[2023-10-29T06:16:31] warn The server returned Endpoints with a different EndpointUrl opc.tcp://milo.digitalpetri.com:62541/milo/discovery than was used to initialize the connection: opc.tcp://milo.digitalpetri.com:62541/milo/discovery. Some servers require a complete match of the EndpointUrl/DiscoveryUrl (including the path) to return all endpoints.
