Release 10.1 introduced a REST-compliant Metasys Monitoring and Commanding
Application Programming Interface (API). This API enables reading, writing, and
commanding of Metasys objects or properties to provide a secure way to bi-directionally
integrate with third-party applications. From Release 12.0, this API includes dynamic
updating using Change of Value (COV) subscriptions. Dynamic updating eliminates the need
for applications that are leveraging the Monitoring and Commanding API to constantly
poll for data, which reduces cost and time on task.
Important: Existing customers who want to upgrade their Metasys Server
software and the Monitoring and Commanding API add-on need to purchase both the
relevant -6 upgrade product code number for the Server software license upgrade and
the M4-APIMOCMD-6 upgrade product code to upgrade the Monitoring and Commanding API.
If existing customers do not purchase both upgrade product code numbers, the API is
no longer functional. Customers who purchased the API upgrade at Release 12.0 need
only upgrade their Server software license to use the API at Release 13.0 or later.
