The channel settings for the modules create the connection from the CMU to the plant configuration and the installed sensors.
ibaDAQ/ibaM-DAQ
You can set the debounce time for the digital inputs on the processor modules ibaDAQ and ibaM-DAQ. The default debounce time value is 5000 µs.
Input modules
Drag the relevant sensor from the plant tree to an empty channel to assign it.
Note:
For this functionality to be available, the sensor must be electrically connected to this channel.
The sensor name is then displayed in the list. The link can be removed by clicking on the Delete icon. The signal type in the channel list is defined by the module itself. Depending on the module, further parameters can be set. To edit the channel parameters, open the channel directly below the module in the plant tree. They can be adjusted under Channel data. For the ICP module, a change to the hardware gain can be made directly in the channel list.
The following information can be seen by expanding the row in the table:
Antialiasing Filter
The antialiasing filter is displayed in % (fixed setting at 33%). The value cannot be changed and is always specified as a percentage of the set sampling rate.
Gain
Logarithmic value for the channel gain in dB (e.g. a setting of 20 dB means a linear factor of 10). Of course, the module hardware must also support this parameter. Details can be found in the manual for the relevant module.
Resolution Max
Maximum value at the channel input combined with the resolution of the AD converter for the module (e.g. 32767 for 16 bit resolution). This value cannot be changed.
Resolution Min
Minimum value at the channel input combined with the resolution of the AD converter for the module (e.g. -32768 for 16 bit resolution). This value cannot be changed.
Output via DO Module
With a digital output module (DO), it is possible to output a virtual trend directly with “High” = Limit exceeded or “Low” = Limit not exceeded. To do this, select a module with digital outputs, e.g. ibaMS32xDO-24V. The selected trends are listed in the Trends column.
Note:
Entire items, for example a bearing or a sensor, can be dragged in from the plant tree using drag & drop to add their trends.
If multiple virtual trends are dragged in, the states are linked to the digital output using a logic OR, i.e. as soon as a limit is exceeded in one of the virtual trends, the digital output is switched.
