3.6.5 c.pCOe expansion cards
c.pCOe is an expansion module that can be used to increase the number of available I/Os.
For details on mounting the c.pCOe expansion cards, see technical leaflet +0500059IE.
The k.Air controller is designed to be able to host up to four c.pCOe cards with serial addresses from 2 to
5; to assign the serial address to the c.pCOe card, the dipswitches on the card must be set as shown in the
figure; the "Ext" dipswitch must be set to "OFF" (no offset).
Important: the dipswitches must be set when the unit is off.
Fig.3.u
In the same way as for serial communication, the factory configuration of the c.pCOe expansion cards is
already set up for communication with k.Air via the FieldBus2 port, with Modbus protocol and baud rate
19.2 kbps. For more details, see manual +0300057EN.
