ADAM-5080 Counter/Frequency Module 1
User's Manual
Overview
Compatible ADAM-5000 Series Main Units
ADAM-5080 is a 4-channel counter/frequency module designed to
be implemented within the following Advantech ADAM-5000 series
main units:
ADAM-5000/485 (withfirmware Version A2.3 orabove)
ADAM-5510 (with library Version V1.00 or above)
ADAM-5510/P31 (withI/O driver VersionV1.00 orabove)
ADAM-5080 4-channel Counter/Frequency Module
With ADAM-5080 4-Channel Counter/Frequency Module, users
can select either counter or frequency mode for data output.
ADAM-5080 offers users a variety of very flexible and versatile
applications such as below:
Counter Mode or Frenquency Mode
If you want to measure the number of input signals for totalizer
function, you may use counter mode to measure quantities such as
movement and flow quantity. Alternatively, you can also select
frequency mode to calculate the instantaneous differential of
quantities such as rotating speed, frequency or flow rate, and
present them in specific engineering formats.
Up/Down or Bi-direction Function
When operating in counter mode, you can choose either the
Up/Down function or the Bi-direction function for different applica-
tion purposes. The counter will count up or down according to
your applications. This counting function helps users obtain the
most accurate data.
Alarm Setting Function
While in counter mode, you can set alarm status--Disable and Latch.
If you want to disable it, you can select Disable.If Latch status is
Please make sure that the ADAM-5080 counter/frequency
module is properly inserted into the compatible main units.

selected, it means the Alarm status will be "latched" whenever the
alarm being triggered. Once the alarm status being "latched," it will
thereafter stay in that triggered state. Users will have to issue a
"Clear Alarm Status" command to return the "latched" alarm status
back to normal. Users can designate the high-limit value and low-
limit value to regulate your alarm behavior through the utility
program.
Digital Output Mapping
Users can either run the utility program or issue a "Set Alarm
Connetion" command to designate a specific digital output module
for the alarm signal to be sent through.

Bi-direction Counting
For implementing Bi-derection Counting, you need to connect
C0B+/D+and C0B-/D- toimplement the control function for
Up/Down Counting.
Features -- Counter Mode
Up/Down Counting
The Up/Down Counter Function offers two types of counting:
Up Couting (increasingly) and Down Counting (decreasingly).
Up Counting : when C0A+ and C0A- sense any input signals, the
counter counts up.
Down Counting : when C0B+ and C0B- sense any input signals, the
counter counts down.
On receiving Up and Down signal simultaneously, the counter will
not perform each specific counting accordingly, but will remain at
the previous counting value, since these simultaneous signals won't
have any effect on counting values.
Figure5Wiring forUp/DownCounting
Note:Ifyou needonly one type of counting,connect C0A+
andC0A- forUp Counting only; or connectC0B+
andC0B- for Down Countingonly.

Features -- Frequency Mode
If users want to select frequency mode, they can only utilize Up
Counting type, and can only connect to C0A+ and C0A-.

UpCounting: when the input signal is within logic level "1", the
counter value increases.
DownCounting: when the input signal is within logic level "0", the
counter value decreases.

Setting Initial Counter Value
In oder to utilize the alarm function, users have to set a high-alarm
limitvalue and/or a low alarmlimit value,and a initial value tofulfill
the requirements for a basic alarm setting.
Figure 8 Setting Alarm Limit
Features -- Alarm Setting
According to your application purposes, you can run the utility
program to set different limit values for High/Low Alarm.

Overflow Value
Overflow value is the number of times the counter value exceeds the
Max/Min values you specified. When the counter value exceeds
Maximum value, the overflow value increases; When the counter
value goes under Minimum value, the overflow value decreases.
Besides, when the counter value runs beyond the range of Max/Min
value, it will continue counting from the initial value. Furthermore, if
users want to check the counter value to see if it is higher or lower
than the Max/Min value, they can run the "$aaSi7" command to gain
a readout of the overflow value.
Getting the Totalizer Value
If users want to get the actual counter value, a formula such as
follows can facilitate an easy calculation from the initial counter
value, overflow value and current counter value:
Vtol= {|Vini-Vmin(or Vmax)|+1}x|Vvf|+|Vini -Vcur|
Vtol : totalizer value
Vini : initial counter value
Vmin : min. couner value = 0 (fixed value)
Vmax :max. counter value= 2 32=4,294,967,295 (fixed value)
Vvf : overflow value
Vcur : current counter value
Example:
If the initial value =10, overflow value =4, min. value = 0, current
counter value = 3, the totalizer value could be calculated as
totalizer value = {|10 - 0| + 1} x| 4 |+ |10 -3| = 51
