Test manager for industrial automation controllers

摘要

An engineering tool for testing a process control system includes one or more test manager instances. Each test manager instance includes circuitry that receives test cases and associated test requests. The circuitry also identifies a target for each test request, translates each test request into instructions to the identified target, checks each test request for validity, initiates execution of each test case, monitors subscribed data generated by the target, computes a difference between the subscribed data at a first point in time and a second point in time, and generates a notification when the computed difference is greater than a predetermined threshold.
