”rS-485” menu
This menu is connected with RS-485 interface, and sets his properties:
Addr
- this parameter defines the address of the device, accordingly to Modbus protocol.
It can be set in range from 0 to 199. If the value 0 is set then device, responds to
frames with address 255 (FFh).
bAud
- this parameter determines RS-485 interface baud rate. It can be set to one of
8 possible values:
1.2
,
2.4
,
4.8 , 9.6
,
19.2
,
38.4
,
57.6
,
115.2
,
which respond to the baud rates of 1200, 2400, 4800, 9600, 19200, 38400,
57600 and 115200 bit/s respectively.
mbAccE
- this parameter sets the access to the configuration registers of the device.
Possible values:
”on”
- configuration registers can be set via RS-485 interface,
”oFF”
- configuration registers can not be set via RS-485 interface.
The access to registers no 05h ÷ 0Eh cant be denied by
mbAccE
parameter
(see:
LIST OF REGISTERS
).
mbtimE
- this parameter defines maximal time (sec) between following frames received by
the device. Parameter
mbtimE
can be set to values from 0 to 99 seconds. The
value 0 means that the time will be not controlled.
rESP
- this parameter defines minimal (additional) delay between the Modbus message
and the answer of the device (received and sent via RS-485 interface). This
additional delay allows the device to work with poor RS-converters which do not
works properly on baud rates higher than 19200. This parameter can be set to one
of values:
”Std”
- answer as quick as possible, no additional delay
” 10c”
” 20c”
” 50c”
”100c”
”200c”
- answer delayed of 10, 20, 50, 100 of 200 chars respectively, where
one character time depends on selected baud rate
