Data acquisition begins usually with components installed on the edge, on premise, on the local factory network. With Logix LogiX we provide proprietary Logix Gate which requires an Industrial PC , Raspberry PI class device or other environment supporting JavaScript runtime. Logix featureswhich:
can handle many communication protocols in parallel - Modbus, OPC, HTTP, SQL. It listen for value changes and send them to our cloud-based processing.
buffers all messages if connection is not available, and send them as soon as it’s back.
sends messages in batches of configurable size.

On cloud side data are received by platform-managed event ingestion service. In most cases it is Azure Iot Hub, which can scale to receive huge amounts of events per second.
Internal Event Bus
Logix LogiX is an event-driven platform: all back-end services communicate using messages exchanged on Azure Service BusEvent Hub (implementing Kafka APIs).
Data processing
Each signal (value change transmitted from the Edge) can trigger rule evaluation in Logix LogiX Processing Engine. It is implemented as state-of-the-art complex event processing engine and it is intended to process huge amounts of events in near-realtime speeds. Rules can be configured as simple expressions or complex scripts.
Processing rules, signals configuration along with factory structure and supporting parameters are maintained in dedicates Logix Serivces LogiX Serivices (LIB/HUB)
Data storage
All data, both incoming raw signals and facts augmented by Processing engine are saved in dedicated storage services: SQL Database for relational queries, Time Series for fast access to temporal data and File (blob) storage for files (i.e. video files)
Domain Services
Logix LogiX backend components supporting domain and client applications are decomposed into separate microservices dedicated to specialized subdomains (ie. Production Order Management, Asset inventory, Reporting/Notfications, User Administration etc). They are deployed as containers using Azure Kubernetes Cluster.
