Counter alarm mode selection

There are no alarm functions in frequency mode (51). There are two counter alarm modes,

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:

Alarm Mode 0

and

 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 High-High alarm <= counter 0 ON ON

Note:

ON OFF

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 threshold 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

1-8

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.

Table 1-6. Frequency mode settings

Command Result - Frequency 0 Result - Frequency 1

$AAB0 to set input mode 0 $AA1H(data) and $AA1L(data)

$AAB1 to set input mode 1

$AAB2 to set input mode 2 $AA1H(data) & $AA1L(data)

$AAB3 to set input mode 3 $AA1H(data) & $AA1L(data)

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

Non-isolated channel 0 and threshold voltage values active

Isolated channel 0 Isolated channel 1

Non-isolated channel 0 and threshold voltage values active

Isolated channel 0 Non-isolated channel 1 and

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).

Operating principle and application notes

INIT*_pin operation principle

All CB-7000 modules contain an EEPROM to store configuration information. To determine the status of the CB-7080 modules, connect the INIT*_pin to the GND_pin and apply power to the module. The CB-7080 modules will go to the factory default setting without changing the EEPROM data. The factory default setting is as follows:

Address = 00 baud rate = 9600 checksum = DISABLED data format = 1 start + 8 data bits + 1 stop bit

To auto-configure the CB-7080/7080D module according to the EEPROM data:

Disconnect the INIT*_pin and GND_pin.

To find the EEPROM configuration data easily in the default setting:

1. Power-down the module, and connect the INIT*_pin to GND_pin.

2. Power-up the module.

3. Send command string $002[0x0D] to the module.

The module returns EPROM data.

4. Record the EEPROM data.

5. Power-down the module, and disconnect the INIT*_pin from the GND pin.

6. Power-up the module.

D/O operation principles

Refer to Digital output application notes on page 1-7 for more information.

 The D/O outputs of CB-7080 and CB-7080D modules are OFF on the first power-up.

 The D/O outputs are changed to the desired state if the “@AADO0D” command is received. Then, all

D/Os will stay in the same states until the next “@AADO0D” command.

 If the host watchdog is active, D/Os do not change, and the module status is set to 04. If the host

computer sends “@AADO0D” to those modules now, those modules will ignore this command and return “!” as warning information. The host must use “~AA1” command to clear the module status to 0, then the CB-7080 and CB-7080D module will accept the “@AADO0D” again.

 If a D/O output is configured as an alarm output, the module controls the ON/OFF state automatically.

The “@AADO0D” command is ignored in this condition.
