ASM is a PC-based HMI system for monitoring, testing and management of analyzers in subsystems or in the complete plant. The relevant information of different analyzers is collected via various communications protocols and saved in a central database. Using the PC's user-friendly operator interface, it is possible to access measured value trends, device states and statistical evaluations, among others, or to start test routines for validation of the results. A comprehensive reporting module that can be tailored to customer requirements is available to document the evaluation.
