Configuration parameters of the "UART1" sub-menu of the "Networks" menu
The following table shows the meaning of the configuration parameters of the "UART1" sub-menu or the "Networks" menu concerning
the RS-485 MODBUS master/slave port.
The parameters are visible if the application software allows the port to be configured to support the MODBUS communication protocol.
PARAM. MIN. MAX. M. U. DEF. DESCRIPTION
Address 1 247 - - - 1
MODBUS address of the device (significant only if the
communication protocol is of the MODBUS slave type)
Baudrate - - - - - - - - - 9600
baud rate of the MODBUS-type communication
1200 = 1.200 baud
2400 = 2.400 baud
4800 = 4.800 baud
9600 = 9.600 baud
19200 = 19.200 baud
28800 = 28.800 baud
38400 = 38.400 baud
57600 = 57.600 baud
Parity - - - - - - - - - EVEN
MODBUS-type communication parity
NONE = none
ODD = odd
EVEN = even
Stop - - - - - - - - - 1 BIT
number of stop bits of the MODBUS-type communication
1 BIT = 1 bit
2 BIT = 2 bit
Timeout 2 240 s 10
local MODBUS-type communication timeout, i.e., device timeout
(this parameter sets a delay from the sending of a request after
which, if no answer is received, the request sending is considered
failed and the next request is sent; it is significant only if the
communication protocol is of the MODBUS master type).
Polarization - - - - - - - - - NO
RS-485 MODBUS slave port polarisation
NO = the device does not polarise the RS-485 slave
port
YES = the device polarises the RS-485 slave port
