User manual - COUNTER SLN-94
7.3.7.
“FiL” parameter
This parameter enables the digital filter, which filters the contacts oscillations of switches
(mechanical detectors). Digital filter eliminates the counting errors when mechanical detectors
are used. This parameter can be set to values:
”OFF”
,
”10”
÷
”90”,
where its value express
the maximum passed frequency, if
”OFF”
is set the filter is disabled (see
DIGITAL FILTER
,
page 18).
7.3.8.
”CAL” menu
This menu contains parameters which define method of pulses recalculation and
presentation.
“muL”
- internal multiplier, range: 1 to 999.
“div”
- internal divider, range: 1 to 999 (this is internal modulo N counter, it means
counter which counts from 0 to selected value, and after that turns to 0 and counts
again),
The displayed value is calculated according to formula:
D
UP
=
integer part of
A
pulses
"div"
×
"mUL"
D
DN
=
round up of
[
integer part of
"Pr1"
"muL"
×
"div"
−
A
pulses
]
×
"muL"
"div"
where:
D
UP
- displayed result while counting UP,
D
DN
- displayed result while counting DOWN,
A
pulses
- number of pulses from counting input {
A
}.
“Pnt”
- decimal point position. I
t changes decimal point position on both displays
7.3.9.
”rS” menu
This menu is connected with RS-485 interface, and sets his properties:
”Adr”
- 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).
”bAu”
- 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”
,
which respond to the baud rates of 1200, 2400, 4800, 9600, 19200, 38400,
57600 and 115200 bit/s respectively.
