The ASM is a PC-based HMI system for monitoring, testing and administration of analyzers in subsystems or in the complete plant. The relevant information of the analyzers is collected over a uniform communications network and saved in a central database. By means of the PC's user-friendly operator interface it is possible to access measured-value trends, device statuses and statistical evaluations, among others, or to start test routines for validation of the results. A comprehensive reporting module is available to document the evaluations.
