6. GRM data communication
This section describes how data communication and
data collection work in Grundfos Remote
Management.
We distinguish between four different types of data:
Data type
Description
These data are used to create trend curves and reports.
They are stored in the CIM 500 and sent every 30 minutes to the server.
Sample data
Sample data can be minimum, maximum and average value of system characteristics, such
as flow rate, head, temperature, etc.
These data are real-time data. They tell you what is going on in the installation right now.
Event data
The data are collected and displayed when you establish a connection to the installation.
They are updated approximately every 5 minutes.
Alarm data are a special type of event data. When a CIM 500 sends an alarm to the central
Alarm data
server, it also delivers a snapshot of event data present for that installation at the time the
event occurred.
Manage
You can send configuration and control commands to a GENIbus device directly via the GRM
commands
user interface.
