In September, we released Neuron 2.2. This version adds a series of new drivers and new features: new Beckhoff ADS, OPC DA, NONA11 drivers are added to unify the ports exposed by HTTP services.In addition, this month, we focus on the construction of data statistics and event alarm system. We plan to feed back the key data statistics and key events in the system through the Prometheus specification in Neuron 2.3, so as to improve the system in Neuron 2.3.NeuronMonitoring and management of it and its connected devices during use.

Data upgrade

The latest version adds a data upgrade script for upgrading from Neuron 1.x to 2.x. At the same time, after Neuron 2.2, the data upgrade is integrated in the installation package. When installing a new version, the data of the old version can be automatically upgraded to the new version Yes, there is no need to configure the device and device point data again after installing the new version.

After the introduction of SQLite in Neuron 2.2 to store Neuron configuration information, Neuron adopts SQL schema to manage the version of the data storage organization format, which is convenient for data upgrade when the version is upgraded.

Key data statistics and event notifications

Neuron will provide a data statistics plug-in based on HTTP and MQTT in version 2.3 to feed back some key data and key events in Neuron.

The statistical information is mainly the statistics of north-south node data, including the number of nodes, the number of running nodes, the number of nodes disconnected from the device, the number of points configured in the south-bound node, the number of bytes of data sent and received by the node, the number of instructions, and Some more detailed state information in the node, such as the delay between the device and so on.

Event notification is mainly within Neuron, and some key changes are used as events to notify the outside. Such as adding, deleting and modifying the relevant configuration and point information of the device, establishing and disconnecting the connection between Neuron and the device, etc.

Among them, the HTTP Server-based interface will summarize statistical information and events in a data format that conforms to the Prometheus specification, which facilitates access to the Prometheus monitoring system to monitor and manage Neuron and its equipment.

upcoming drive

QnA 1E driver

This driver is similar to the existing driver QnA 3E, it is mainly connected to some older models in Mitsubishi PLC, and supports communication through serial port connection. The supported data types are the same as those of QnA 3E, including commonly used data types.

CNC FANUC driver

This driver is mainly used in CNC (Numerical Control Machine Tool), interacts with FANUC’s CNC machine tool, and obtains some basic information of the machine tool, such as spindle speed, distance, absolute and relative position information, etc.
