User manual for universal counter with batching function SLIK-73
where:
W - displayed result
L
m
- the internal main counter value
L
w
- the internal (modulo) precounter value
Parameter
“div”
can't be set to “000000”, entered value is controlled by firmware.
The precounter (modulo) and main counter are internal registers of the counter's
firmware and they contain not calculated (by
mul
and
div
parameters) numbers of pulses
delivered to the counting inputs {A} and {B}. The modulo counter contains the fractional part of
the result (ratio of
„div”
parameter). Main counter contains the integer part of the result (not
recalculated). If parameter “
div
” is set to 1, then main counter contains the number of all
pulses delivered to counting inputs.
Firmware uses fixed point arithmetic (rounding down).

”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 04h ÷ 08h 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:
27
