Expansion model
In future there are different 2-port flexotron®800 models (Available only on request).
For a list of the different models, see the flexotron®800 model overview in chapter 2.
17.1
Port 1
On a 2-port flexotron® 800, port one is used for connection to CASE flexotron® and
possibly a SCADA system. On an WEB model, port 1 is the TCP/IP output.
17.2
Port 2
Port 2 is used for expansion units, e.g. expansion controllers and the Vacon NXL/Lenze
SMV/Omron/Emerson frequency converters. A maximum of two frequency converters
and two expansion controllers can be connected. The controllers must be of the type
flexotron® 800. There is no point in utilising slave controllers with display since the
display cannot be used or show anything. However, an external display is required
when starting up slave controllers without display for the first time (if the configuration is
not done via CASE flexotron®). All configuration takes place either via CASE flexotron®
or via the display on the master controller. All inputs and outputs can be viewed in the
master controller. For configuration of port 2, see section 16.27.2.
Frequency converters and expansion units can be used together, connected to port 2.

Wiring
17.3.1
Vacon/Lenze/Omron/Emerson frequency converters
If the flexotron®800 is intended to control of one or two of the Vacon NXL/Lenze
SMV/Omron V1000/Emerson frequency converters, Modbus communication via port
two is utilised.
17.3.2
Expansion controllers
Communication between the master and expansion controllers takes place via prioritary
bus. The slave controllers will be given the addresses 241:1 and 241:2 (ELA:PLA)
respectively.
