User Manual For - CONTROLLER/DATA RECORDER MultiCon CMC-99/141
Counters parameters are:
–
Name
– each built-in input already has a name given by the device and user cannot
change it, for description of
Name
parameter see
Fig. 7.75
,
–
Unit
– read only parameter, it is
Pulses
,
–
Low Limit
– value determining amount of pulses, bellow which in logical channel will
be displayed
Lo
state,
–
High Limit
– value determining amount of pulses, bellow which in logical channel will
be displayed
Hi
state,
–
Function mode
– specifies the pulse counting:
•
A + B
– every rising edge on both inputs increments counter value,
•
A - B
– every rising edge on input 1 increments counter value and every rising
edge on input 2 decrements counter value,
•
quad 1
– counter becomes an encoder element used to measure pulses on
inputs using quad method. Direction of counter value changes depends on input
2 state (0 - down, 1 – up), and counting take place when on input 1 rising edge
appears,
•
quad 4
– counter becomes an encoder element used to measure pulses on
inputs using quad method. Direction of counter value changes depends on input
1 (2) state (0 - down, 1 – up), and counting take place when on input 2 (1) rising
edge appears. Thanks to this method user gains four times higher measurement
resolution,
–
Reset now
– button which allows user to manually reset the counter,
–
Reset mode
– it allows to choose an additional resets for the counter, it has
following parameters:
•
disable
– no additional resets,
•
from log. channel
– an additional reset is logical channel selected from list in
Reset source
parameter, it is activated by high state,
•
external
– an additional reset is
Res.
input, activated by high state,
•
both
– both of options shown above are active,
–
Reset source
– this parameter is visible when
Reset mode
is set as
from log. channel
or
both
, it contains a list of logical channels and the chosen one
will reset the counter when its value is higher than
0
,
–
Prog. inp. mode
- specifies counter reaction on higher than
0
value appearance on
Prog. input
; it has following parameters:
•
disable
–
Prog.
input is inactive, any changes on this input will be ignored,
•
direction
– it allows to change mode or counting direction. When
Function mode
parameter is set as:
◦
A + B
– active
Prog.
input changes mode to
- (A + B)
,
◦
A - B
– active
Prog.
input changes mode to
B - A
,
◦
quad 1
– active
Prog.
input changes counting direction,
◦
quad 4
– active
Prog.
input changes counting direction,
•
inhibit
– it allows to temporary stop pulses counting,
–
Filter
– sets filter on counter inputs which allows to getting rid of negative effects of
signal bounces; it has following parameters:
•
disable
– filter is inactive, recommended only in situation when to counter input
is connected electronic input of other device,
•
10 ÷ 90
– filter is active; setting one of frequencies causes that input signals
which duration corresponds to half of the selected frequency, will be considered
as a unwanted signal bounces and ignored. Using this option is recommended
when to counter input is connected contact output of the other device,
