Networking Features

Alarms can be enabled to monitor both analog and digital signals with fixed, adjustable, and tracking alarm limits. Alarm limits can be defined for high high, high, low, low low, rate of change, and digital alarms. Further customize your alarm conditions with a dead band, and even automate the tracking of alarm conditions to disable or enable them based on time of day or any other value within the system. OPC UA and OPC Alarm and Events can also be a source of alarms along with all OAS IIoT data sources.
