3. Applications
The CIU 850 is a gateway for connecting a Modbus
RTU/TCP network to Grundfos Remote
Management.
Grundfos Remote Management
Grundfos Remote Management is a web-based
solution for monitoring and control of networks. It
allows you to access information and control pumps
remotely using an ordinary computer or mobile
device. You must have a contract with Grundfos to
access GRM.
CIU 850 - Modbus RTU/TCP communication
The gateway functions as a Modbus RTU/TCP
master. It can be connected to Modbus RTU slave
devices via a wireless radio or wired (serial)
connection. A radio modem (SATELLINE-3AS or
similar) is required for wireless connection.
It can be connected to Modbus TCP slaves through a
external wireless 3G or 4G router or via an RJ45
connector to the network.
CIU 850 - GRM communication
The CIU 850 communicates with GRM via an HTTP
TCP/IP Ethernet connection. A connection and a
network router with Internet access or a wireless
modem (GPRS or similar) is required.
