Help - HMI Monitoring
Overview:
The HMI server offers the ability to monitor the following features:
HMI Protocol Messages:
The system keeps a temporary record of the most recent HMI requests and responses in a buffer. Selecting the "HMI Messages" menu will display these messages in a list, with the newest messages at the top, and the oldest at the bottom. These messages are in "raw" format, showing you the actual data being transmitted. This page can be useful in diagnosing communications problems between HMI clients (web pages) and the HMI server.
Field Data Messages:
The system keeps a temporary record of the most recent field device requests and responses in a buffer. Selecting the "Field Data Messages" menu will display these messages in a list, with the newest messages at the top, and the oldest at the bottom. These messages are in a processed format, showing you the contents of each message in human readable format. This page can be useful in diagnosing communications problems between the HMI server and the field device server acting as the source of the data.
