AUTOSOL Edge ACM is a suite of applications installed on a field device that work in conjunction to poll real-time data and publish it using standardized Sparkplug B message formatting. There are five applications that make up AUTOSOL Edge ACM and are managed by the AUTOSOL App Manager. These five are:
eACM/Edge ACM: The polling engine that collects data from the field device using native protocols.
Enables report-by-exception data to be sent to any MQTT broker
Provides backfill for data retention during communication outages.
AUTOSOL MQTT: The publisher that publishes the polled data to a broker and can receive “writes” from a broker intended for the connected end device.
Azure: The native MS Azure Connector used when communicating with Azure enabled services.
File Handler: Publishes files via MQTT in Base64 format.
Priority Forward: Enables multiple connections to a single serial device port; directs traffic per user defined rules to avoid communication interruptions
AUTOSOL App Manager and Edge Manager
The AUTOSOL App Manager and Edge Manager are built-in, easy-to-use web pages used for configuration. The Edge Manager exists on the field devices and allows configuration of only that device. The AUTOSOL App Manager exists on a centralized Windows computer and allows configuration of multiple AUTOSOL Edge Nodes with lower bandwidth requirements than directly accessing their configuration websites.
Native Polling Protocols
eACM currently supports Modbus, Totalflow, ROC, FloBoss, and ControlLogix.
