Temperature Units is ignored for the resistance device inputs for channels 4
and 5. However, Engineering Units x 10 is used for these channels to receive
actual resistance in ohms in the tag database. The Excitation Current for
channels 4 and 5 must be 0.5mA. The Open-Circuit Selection is Upscale. This
means that if an open-circuit or short-circuit condition should occur at any of
the 6 input channels, the input value for that channel is the full-scale value
selected by the input type and data format. We can therefore monitor each
channel for full scale (open-circuit) as well as monitor the Open-Circuit bits in
Input word 6, for each channel. When complete, the configuration screen
looks like the following:
Click OK and your configuration for the 1769-IR6 RTD Input module is
complete.
