Operating guide
2.0 Introduction
2.1 Use 3G or 4G mobile internet connection when wired internet connetion is not available
The ECL Comfort 296 / 310 controller can be connected to a SCADA
system via a 3G or 4G mobile internet connection if a wired internet
connection is not available. Some important limitations and
restrictions apply however, if a 3G or 4G mobile internet connection
is used.
2.2 Designed to handle mobile internet
When a connection is less reliable then the SCADA server and the
ECL Comfort 296 / 310 controller may experience the connection to
be lost.
This situation sets higher demands for mechanisms to re-establish
the connection and also higher demands for retransmission and error
handling mechanisms.

Mobile internet connections are in general to be considered as being
less reliable and having lower data throughput than wired internet
connections.
The Danfoss ECL Comfort 296 / 310 controller and OPC Server are
designed to handle mobile internet connections being less reliable
than wired internet connections.
The OPC Server software must, however, be configured accordingly.
