9 SERIAL PORTS
Controllers EV3 MVC and EVD MVC have the following serial ports:
- INTRABUS baud rate 19,200, even, 1 stop bit
proprietary communications protocol INTRABUS node 1 (MASTER)
- RS-485 baud rate from parameter C61 (default 9600)
even from parameter C62 (default even)
stop bit from parameter C63 (default 1)
MODBUS SLAVE communications protocol node from parameter C22 (default=1).
The MODBUS RS-485 serial port can be used to communicate with a supervision system or a personal computer.
The document “MODBUS IMPLEMENTATION TABLE” (document code 1463DMVC104) describes the resources of the devices accessible
via the RS-485 serial port. The document is available on the www.evco.it website.
The INTRABUS serial port enables a remote keypad (EVK3K11 or EVJ LCD) to be connected to the EV3 or the EVD MVC controller.
