3. Set the gain and offset for each channel.
See the Thermocouple/Millivolt Input Module User Manual,
publication
, for more information.
4. If desired, enable real-time sampling (RTS) and set the sampling
rate, from 0.1 to 3.1 seconds.
This becomes the effective data update rate and may override
the update rate if the update rate is smaller.
5. Set the Update Time for the module’s block transfer.
The range is 1 to 16382 milliseconds. This sets the requested
update rate; the actual rate depends on the baud rate, the
number of racks on the RIO network and whether block
transfers are running to other modules in the same rack.
I/O Data
The 1771-IXE module returns 9 words of floating point data.
This data can be mapped to a numeric read tag.
