17.29 Communication
17.29.1 Modbus communication
Corrigo can be connected to a network for Modbus communication.
Modbus
communication
slave, port 1
Not Active
If Modbus communication is activated, you can set the address etc.
Modbus communication takes place using 1 stop bit.
Modbus address: 1
Speed: 9600 bps
Two stop bits:Yes
Parity:No
NOTE: Only one stop bit can be used.
Slave
For connection to E tool

and a Modbus SCADA system.
Function port1 
Slave
Expansion unit
In order to connect additional I/Os (in- and outputs) to the Corrigo, port 1 or 2 should be set as an
expansion unit (only Corrigo controllers can be connected). It is possible to connect two expansion
units, giving a maximum number of 28*3 = 84 inputs/outputs. The expansion units must have the
addresses 241:1 and 241:2 respectively (ELA:PLA).
Expansion unit1
None
Expansion unit2
None
To initiate the expanded controllers, select ”Expansion unit” at start-up (see below). If the controller
does not contain program version 3.0 or later, the initiation must be made via E tool
©
(see the E tool
©
manual). However, this requires that the controller hardware is of a second generation Corrigo (…S).
After initiating the expansion units and setting the master controller, all inputs and outputs are
available for configuration in the master controller under "Configuration" / "Inputs/Outputs" (the
expansion units’ in-/outputs are named Exp1/Exp2).

Frequency converters
Up to four separate Vacon NXL / Lenze SMV/ Omron V1000 / Emerson Commander/ LS iG5a/ LS
iS7/ EBM-PABST/ Danfoss FC 101/ ABB ACS/ ECBlue frequency converters can be controlled
using Modbus communication. The Corrigo can handle two parallel supply air fans and two parallel
extract air fans. Miscellaneous alarms and indications can be read from the frequency converters. For
a complete list of alarms, see the alarm list. For communication addresses see “Appendix 1”, located
at the end of this manual.
The Corrigo Modbus settings are listed below. They are not adjustable and must also be set in the
current frequency converters.
