7.9.5.10. Optoisolated universal counters modules
The CP modules can be equipped with two or four universal counters inputs (see
Appendices 8.10. CP2, CP4 – OPTOISOLATED UNIVERSAL COUNTERS MODULES ).
Each counter can be configured individually and is equipped with two counting inputs:
Inp[n]1
,
Inp[n]2
, programming input
Prog[n]
, reset input
Res[n]
, where
n
means a counter
number from 1 to 4.
The counters parameters are:
– Name – each built-in input already has a name given by the device and the user
cannot change it, for the description of the Name parameter see Fig. 7.81 ,
– Unit – a read only parameter, it is Pulses ,
–
Low Limit
– the value determining the amount of pulses, below which the
Lo
state
will be displayed in the logical channel,
–
High Limit
– the value determining the amount of pulses, above which the
Hi
state
will be displayed in the logical channel,
– Function mode – specifies the pulse counting:
•
A + B – every rising edge on any input increments the counter value,
•
A - B
– every rising edge on input 1 increments the counter value and every
rising edge on input 2 decrements the counter value,
•
quad 1 – the counter becomes an encoder element used to measure pulses on
inputs using the quad method. The counter value direction changes depending
on input 2 state (0 - down, 1 – up), and counting takes place when the rising
edge appears on input 1,
•
quad 4 – the counter becomes an encoder element used to measure pulses on
inputs using the quad method. The counter value direction changes depending
on input 1 (2) state (0 - down, 1 – up), and counting takes place when the rising
edge appears on input 2 (1). Thanks to this method the user gains four times
higher measurement resolution,
– Reset now – the button which allows the user to reset the counter manually,
– Reset mode – it allows to choose an additional reset for the counter, it has
the following parameters:
•
disable – no additional resets,
•
from log. channel
– an additional reset is a logical channel selected from the
list in the
Reset source
parameter, it is activated by a high state,
•
external – an additional reset is the Res. input, activated by a high state,
•
both – both options shown above are active,
–
Reset source
– this parameter is visible when the
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 the counter reaction to higher than 0 value appearance
on Prog. input ; it has the following parameters:
•
disable
–
Prog.
input is inactive, any changes on this input will be ignored,
•
direction – it allows to change a mode or a counting direction. When
the Function mode parameter is set as:
◦ A + B – active Prog. input changes the mode to - (A + B) ,
◦ A - B – active Prog. input changes the mode to B - A ,
◦
quad 1
– active
Prog.
input changes the counting direction,
◦
quad 4
– active
Prog.
input changes the counting direction,
