17.29.1 Modbus communication
Corrigo can be connected to a network for Modbus communication.
Modbus slave com-
munication, 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.

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).

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 two separate Vacon NXL / Lenze SMV / Omron V1000 / Emerson Commander / LS iG5a /
LS iS7 / EBM-PABST / Danfoss FC 101 frequency converters can be controlled via Modbus
communication. 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 the Corrigo
variable list. Information is also available at the end of this manual.
The Corrigo Modbus settings are listed below. They are not adjustable and must also be set in the
Vacon NXL/Lenze SMV/Omron V1000/Emerson Commander/ LS iG5a / LS iS7 / EBM-PABST /
Danfoss FC 101 frequency converters.
