3 Features and Functions
The Multifunction Module
The multifunction module (DAQM907A) adds two additional measurement input capabilities to the system: digital
input and event totalize.
The multifunction module also contains a dual voltage output (DAC). For more details, see
Transducers and
sensors.
Digital input
The multifunction module has two non-isolated 8-bit input/output ports which you can use for reading digital
patterns. You can read the live status of the bits on the port or you can configure a scan to include a digital read.
Each port has a separate channel number on the module and contains 8-bits. You can combine the two ports to read
a 16-bit word.
Totalizer
The multifunction module has a 26-bit totalizer which can count pulses at a 100 kHz rate. You can manually read the
totalizer count or you can configure a scan to read the count.
You can configure the totalizer to count on the rising edge or falling edge of the input signal. The maximum count is
26
67,108,863 (2
-1). The count rolls over to "0" after reaching the maximum allowed value. You can configure the
totalizer to read without affecting the count or reset the count to zero without losing any counts.
