Registration Numbers listed in the left column refer to the position where the software has registered
the I/O module. Registration Number will not necessarily be the same as the physical position of the
module in the system. To change the Registration Number of an I/O module, click the box in the left
column next to the Registration Number, then use the Up and Down buttons to move the module
within the sequence. The system automatically reassigns the I/O modules above and below the one
moved. Repeat for other modules if desired. The MAQ20-COMx module always has Registration
Number 0 and cannot be moved.
Press ‘Save’ to save the new configuration. The new registration
sequence is permanent across power cycles and any other system configuration as long as I/O
modules are not removed from or added to a system.
13.0 Range Selection, Channel Enable & Reading Signals
The MAQ20-RTD31 module has three user selectable sensor types and five user selectable input
ranges. The MAQ20-RTD41 module has two user selectable sensor types and four user selectable
input ranges. Sensor type and input ranges are selectable on a per-channel basis. Over-range and
Under-range up to 2% beyond the specified input values will be measured as applicable for each
sensor type and range. Sensor linearization is performed in the module and accuracy is guaranteed
to ±f.s. The
following the
and the
at the end of this manual show the
sensor types, input ranges, and input temperature to counts mapping for each of the two modules.
The Range Table for the MAQ20-RTD31 module is shown below for reference.
