Chapter 17 Expansion model
There are eight different 2-port Corrigo models with 15/28 inputs/outputs, with or without display,
and with or without TCP/IP port. For a list of the different models, see page 8 (Corrigo E model
overview).
17.1 Port 1
On a 2-port Corrigo, port 1 is used for connection to E tool and possibly a SCADA system. On an
Exx2S-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 frequency
converters. As a maximum, either two frequency converters or two expansion controllers can be
connected. The controllers must be of the type Corrigo E. 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 done via E tool). All configuration takes place either via E tool 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 16.26.2.
17.3 Wiring
17.3.1 Vacon frequency converters
If the Corrigo is intended to control of one or two of Vacon’s NXL frequency converters, Modbus
communication via port 2 is utilised.
17.3.2 Expansion controllers EXOline
Communication between the master and expansion controllers takes place via EXOline. The slave
controllers will be given the addresses 241:1 and 241:2 (ELA:PLA) respectively.
