nc-link-gateway is a server process that connects to MTConnect agents and provides an NC-Link interface according to NC-Link Specification.
Usage:
nc-link-gateway [config file - default is nc-link-gateway.cfg]
# MTConnect agents information
agents:
#
# - name: <device name>
# id: <device id prefix for NC-Link>
# url: <MTConnect Agent url>
# freq: <poll period in seconds>
#
# Sampling and upload interval (ms) for Samples, Events and Conditions - optional
# Override defaultSampleInterval and defaultUploadInterval
#

agents
name / url / frequency : Specify the MTConnect agent's URL and how often to poll the data.ampleInterval_Sample : Specify the time interval of sampling the Sample data.sampleInterval_Event : Specify the time interval of sampling the Event data.sampleInterval_Condition : Specify the time interval of sampling the Condition data.uploadInterval_Sample : Specify the time interval of publishing the Sample data. Upload Interval must be equal or greater than its Sample Interval.uploadInterval_Event : Specify the time interval of publishing the Event data. Upload Interval must be equal or greater than its Sample Interval.uploadInterval_Condition : Specify the time interval of publishing the Condition data. Upload Interval must be equal or greater than its Sample Interval.server
port : The port number that the OPC UA server will serve.user/password : If not specified, use an anonymous login.defaultSampleInterval - default sampling intervals in milliseconds for any data types if they are not specified.defaultUploadInterval - default publishing intervals in milliseconds for any data types if they are not specified.mode : Select agent or adapter.agent mode is to incorporate the MQTT broker as part of the NC-Link server. Set up key/cert parameters.key/cert File : MQTT server's certificate and its key file.adapter mode is to connect to an external MQTT broker. Set up mqtt and cacert parameters.mqtt : the hostname of the external MQTT broker.cacert : CA cert file for the client connection.
