Parameters for ES930: Digital In Tab

Shows a consecutive number for each entry in the hardware configuration table.

You cannot edit this field.

Use this checkbox to enable or disable this signal for further configuration steps.

Disabled signals will not be available in the Experiment Environment.

You can also use the context menu commands Enable All Channels and Disable All Channels to enable or disable all channels at once that are displayed on the selected tab.

Shows the digital input mode of this channel (state, counter or timer).

You cannot edit this field.

This column shows the name of the hardware channel.

Shows the name of the measurement variable assigned to this channel. The name can be edited. It must be unique for the whole configuration.

Defines the default acquisition rate necessary for your measurement task.

The acquisition rate can be selected separately for each channel of a device. It is used as default rate within the measuring environment (e.g. INCA Experiment Environment), but you can overwrite it (e.g. in INCA's Configure Variables dialog). Some signals of a channel require the same acquisition rate for all signals to ensure consistency of the measure data, e.g. active time and inactive time when measuring in the mode PWM Out.

Enter the unit according to the signal to be measured.

The selected unit appears in the corresponding measure windows.

Select the active state of the signal.

• High

  Normal logic is applied, i.e. HIGH is interpreted as active state.

• Low

  Inverse logic is applied, i.e. LOW is interpreted as active and HIGH as inactive state.

Define what items are to be counted. The setting can only be edited for counter signals.

• Active-Inactive

  Counts all active-inactive edges.

• Inactive-Active

  Counts all inactive-active edges.

• Both

  Counts all active-inactive and inactive-active edges.

• Cycle

  Counts all cycles.

Define how the relevant measurement period is determined. The setting applies to the signals "active time" and "inactive time" of a hardware channel.

• Absolute

  The measurement goes from the beginning of the measurement to the current sample point, i.e. the timer value continuously increases unless the reset configuration applies.

  

• Pulse

  The time measurement starts with a pulse and includes an active and inactive state in arbitrary order, i.e. the duration of the last complete pulse gets measured.

  

  Note
  If the time measurement starts with a pulse, the sum of the duration of the active and the inactive state does not necessarily equal the duration of the period because they can belong to different periods. The sum only equals the period if the pulse that is the starting point of the time measurement is also the starting point of the period.

• Period

  The time measurement starts at the beginning of a period, i.e. the duration of the last complete period gets measured.

• Cycle

  The time measurement starts at the beginning of a cycle, i.e. the duration of the last complete cycle gets measured.

This setting can be edited for Counter and Timer signals.

For counters, it defines when the counter will be reset in order to restart counting.

For timers, it defines when the timer will be reset to measure the next time period. The setting applies to all of the active time and inactive time of a hardware channel. It can only be edited if the value Absolute is selected in the Relevant Period column.

• Off (free running)

  The count / time measurement goes from the absolute beginning of the measurement to each sample point, i.e. the value continuously increases. Please note that depending on the length of the measurement, overflow can occur in this mode.

• sample point

  The counter / timer is reset each time a new sample is generated by the measurement module.

For rapid prototyping use cases, the option "Sample point" should be selected.

Select whether a PWM period starts with an active-inactive or an active-inactive edge of the signal.

• Active-Inactive

  The PWM period starts with an active-inactive edge. It consists of a sequence of an inactive pulse with a subsequent active pulse, i.e. a LOW value is followed by a HIGH value in normal logic.

  

• Inactive-Active

  The PWM period starts with an inactive-active edge. It consists of a sequence of an active pulse with a subsequent inactive pulse, i.e. a HIGH value is followed by a LOW value in normal logic.

Enter the number of periods that each cycle consists of.

You can enter any number between 1 and 4095.

Determine whether timeout control is to be enabled or disabled.

• On

  Timeout control is enabled. You can now set in the Timeout [s] column the time after which a timeout shall occur.

• Off

  Timeout control is disabled.

Set the period in seconds after which a timeout shall be detected.

You can enter any time between 0 and 64.4 s. A timeout of 0 s means that timeout is disabled.

If there is no signal transition within the defined duration for the timeout, the (in-) active time provides the last measured value. Moreover, the corresponding diagnosis signal will get the value TRUE.

Determine whether a glitch filter is to be used on the input stage of the hardware channel. If enabled, it will be used for simple de-bouncing and elimination of unwanted spikes.

• On

  The glitch filter is enabled. You can now set in the Glitch Filter Time [ns] column the minimum duration of a pulse. Smaller pulses are ignored, only larger pulses are considered.

• Off

  The glitch filter is disabled.

Set the period in nano-seconds that determines whether a spike is to be regarded as unwanted and therefore filtered out by the glitch filter.

You can enter any value between 120 and 3000 ns; the resolution is 15 ns.

A value of 0 ns means that the glitch filter is disabled.

Enter the lower physical value according to the sensor used.

You can find this value in the datasheet of your sensor.

Enter the upper physical value according to the sensor used.

You can find this value in the datasheet of your sensor.

Enter the value of the lower sensor signal according to the lower physical value.

Enter the value of the upper sensor signal according to the upper physical value.

When you click into this field, an editor opens where you can create special conversion formulae.

Enter the lower limit of the expected physical measurement range.

This value is used together with the values of the Phys bottom, Sensor bottom and Formula parameters to calculate the amplification factor.

The highest amplification factor possible is selected to ensure that none of the connected channels is overloaded.

Enter the upper limit of the expected physical measurement range.

This value is used together with the values of the Phys top, Sensor top and Formula parameters to calculate the amplification factor.

The highest amplification factor possible is selected to ensure that none of the connected channels is overloaded.

Shows the lower physical limit of the measurement range actually possible for this channel.

This value is determined by the values of the Phys bottom, Sensor bottom and Formula parameters as well as by the actual measurement range of the module.

You cannot edit this field.
