MODBUS FEATURES
Serial ports (Modbus RTU)
The physical communication line is compliant with EIA-RS485 standard (2 wire half-duplex mode).
For Modbus communication, it is also possible to use the RS232 port (P2P mode).
For Modbus, protocol RTU (Remote Terminal Unit)will be used.
The serial baudrate can be selected among:
1200 bps, 2400 bps, 4800 bps, 9600 bps, 19200 bps, 28800 bps, 38400 bps, 56000 bps, 57600 bps, 115200
bps
The RTU byte is composed by 11-bit:
•
1 start bit
•
8 data bit
•
1 parity bit (NONE, ODD, EVEN)
•
1 or 2 stop bit (2-if parity is set to NONE)
Ethernet port (Modbus TCP)
It is possible to connect Modbus TCP devices to the ethernet ports eth0 and eth1.
The network configuration (device IP and subnet) has to be initially set by using the integrated web server.
