Introduction
CB-7000 is a family of network data acquisition and control modules. They provide A/D, D/A, DI/O,
Timing/Counting and other functions. These modules can be remote controlled by a set of commands.
The common features of the CB-7080 and CB-7080D include:
 Two independent 32-bit counters, counter 0 and counter 1.
 Input signals can be isolated or non-isolated.
 Programmable digital filter for isolated and non-isolated input.
 External gate control for isolated and non-isolated input.
 Programmable threshold value for non-isolated input.
 Programmable alarm output.
 Input frequency measurement up to 100 kHz.
The CB-7080D module identical to the CB-7080 with a 5-digit LED display added. The LEDs can display the
counter value and input signal frequency without PC control.

Counter alarm mode selection
There are no alarm functions in frequency mode (51). There are two counter alarm modes, Alarm Mode 0 and
Alarm Mode 1 . These two alarm modes can be used in both CB-7080 and CB-7080D.
Alarm Mode 0 is used for two-channel applications, as follows:
 To select alarm mode 0: ~AAA0 (for both channels)
 To enable channel 0: @AAEA0
 To disable channel 0: @AADA0
Set the High alarm limit of channel 0: @AAPA(data)
 if (counter 0 >= alarm limit 0)  D/O 0 turn ON
 if (counter 0 < alarm limit 0)  D/O 0 turn OFF
 Enable channel 1: @AAEA1
 Disable channel 1: @AADA1
Set the High alarm limit of channel 1: @AASA(data)
 if (counter 1 >= alarm limit 1)  D/O 1 turn ON
 if (counter 1 < alarm limit 1)  D/O 1 turn OFF
Alarm mode 1 is used for single-channel applications, as follows:
 Select alarm mode 1: ~AAA1 (for channel 0 only)
 Enable channel 0: @AAEAT
 Disable channel 0: @AADA
 Clear latch alarm: @AACA
 Set High alarm limit: @AAPA(data)
 Set High-High alarm limit: @AASA(data)
Counter 0 < High alarm OFF OFF
High alarm <= counter 0, and
counter 0 < High-High alarm
ON OFF
High-High alarm <= counter 0 ON ON
Note:
The High-High alarm must greater than the High alarm.
Digital output application notes
The D/O0 and D/O1 can be used as D/O or an alarm output, as follows:
 D/O in the frequency mode.
 D/O in the counter mode and alarm disabled (by @AADA or @AADAN command).
 An alarm output in the counter mode and an alarm enable (by @AAEAT or @AAEAN command).

Programmable t res old voltage setting
The programmable threshold voltage is valid for a non-isolated input of counter mode (50) and frequency
mode (51). The default settings are:
 TTL compatible
 Low trigger level = 0.8 volt
 High trigger level = 2.4 volts
You can change the high trigger level by the $AA1H (data) command. The low trigger can be changed by the
$AA1L (data) command. The high trigger level must be greater than the low trigger level.
Digital filter setting
The digital filter is disabled in frequency mode (51). It is designed as a pulse-width filter for both high/low
pulses, and is valid for both non-isolated and isolated inputs. The digital filter can be enabled or disabled. Key
points of digital filter usage include:
1. Use $AABS to select the input signal.
2. Use $AA0H(data) to set the minimum width of high level.
3. Use $AA0L(data) to set the minimum width of low level.
4. Use $AA4S to enable/disable the digital filter (both channels).
If the high width of the input signal is smaller than the minimum high width of digital filter, the input signal is
filtered out. Also, the low width of the input signal must be greater than the minimum low width of digital
filter.
For example, if the width of the input signal is >1000 µs, set the digital filter at 900 µs. Therefore, all noise
<900 µs is filtered out by the digital filter. These steps are given as follows:
 $AAB0
 $AA0H00900
 $AA0L00900
 $AA41

CB-7080 & CB-7080D Counter/Timer User's Guide Application notes

Gate control setting
The gate control is ignored in frequency mode (51). The gate control is disabled in counter mode (50) by
default. Use the following commands to enable/disable the gate control:
 When you use the $AAA0 command, the gate input must be low to enable the counter.
 When you use the $AAA1 command, the gate input must be high to enable the counter.
 When you use the $AAA2 command, the gate input is disabled. The counter is
always enabled.
Preset value setting
The preset value is ignored in frequency mode (51). The counters go to their preset value in the first power-on
state. The reset counter command, $AA6N, also forces the counters to go to their preset value. The default
preset value is 0. Use the $AAPN(data) command to change the preset value. The key points include:
Table 1-5: Preset values
Factory default setting Counter preset value is 0
Power on state Counters 0/1 are set to the preset value
$AA6N Counter N is set to the preset value
$AAPN(data) Sets the preset value of counter N
Frequency input applications
To set the module to frequency mode set the configuration code to 51in the Set module configuration
command.

To measure frequency:
1. Use the $AA1H(data) and $AA1L(data) commands to set the threshold voltage values, if the frequency
input is a non-isolated input.
2. Use the $AAB? command to select the mode (this command will clear the current frequency first).
3. Use the #AA? command to perform frequency measurement.
Only four commands are important in frequency measurement mode:
$AAB? Select mode
$AA1H(data) Set high-level threshold value
$AA1L(data) Set low-level threshold value
#AA? Perform frequency measurement
The status-read-back commands are:
$AAB? Mode read back
$AA1H High_level threshold value read back
$AA1L(data) Low_level threshold value read back

General syntax format
Commands are constructed with individual pieces of information represented as code. Each command is
structured as follows:
 One-character Delimiter that indicates the type of command to execute.
 Two-character HEX module address, from 00 to FF
 Function, which indicates the task to execute.
 Terminator character, to indicate the end of the command.
This section lists the commands to use to perform specific functions. When writing a command, replace the
generic address with the address of the module you want to perform the task on. For example, to read the
name of module 1:
Select $AAM, the command used to read the name of a module (see page 35).
1. Replace the address (AA) with 01, to indicate module 1.
2. Terminate the command with a carriage return (cr).
This command would then be written as $01M(cr).
