D-6 Configuring Your 1769-IR6 RTD/resistance Input Module in a Remote DeviceNet System with a 1769-ADN DeviceNet Adapter
temperature data in degrees F. For the thermocouple used, the default
Excitation Current of 1.0 mA is used.
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.
Refer to your Compact™ I/O 1769-ADN DeviceNet Adapter user’s manual,
publication number 1769-UM001A-US-P, for information concerning
DeviceNet network configuration and operation.
