Chapter 4 Measurement Definition
Module Definition - Define Module Functionality Page
Define two channels for the sensor. One must be a Dynamic channel for the
vibration measurement, the other a Static channel, which is used to read the
temperature measurement.
The Dynamix 1444-DYN04-01RA module includes two Analog-to-Digital
Converters. One ADC is connected to channels 0 and 1 and the other is
connected to channels 2 and 3. While the module allows significant
individuality in channel configuration, the rate the ADC samples must be the
same for both channels in the pair it serves. Consequently it can be
advantageous to use the same pair for both vibration and temperature
measurements. Use of both measurements allows greater flexibility to define
the dynamic channels since they then do not share ADC. For example, if two
AT sensors are connected to the module, then wire the vibration signals to
channels 0 and 2, and the temperature signals to channels 1 and 3. As a result,
the sample rate (FMAX) for each of the two vibration channels can be set
independently.
Module Definition - Input Data Page
It is not necessary to configure a tag to communicate the temperature value to
the controller*. However, if a tag is required, then for the static channel that is
used with the sensor, select the Proportional DC tag for input.
*Add this tag if a specific calibration offset is measured rather than a nominal
value entered.
