The Web Server hosts the web pages for both configuring and operating equipment line performance monitoring using, for example, MES Web Portal and MES model-driven application content accessed on Work Tasks Enterprise Console. If using Enterprise Integration, the Web Server also hosts the corresponding configuration and monitoring web pages for Enterprise Integration.
This server can reside in the corporate domain or plant domain depending on its usage. This server should have a dedicated MES middleware for managing all the client transactions. The MES middleware also provides access to the MES Web API.
