Module Data, Status, and Channel Configuration for the Output Modules 4-11
1769-OF2 Fault Value (Channel 0 and 1)
Using words 2 and 4 for channels 0 and 1, you can specify the values the
outputs will assume when the system enters the fault mode. The default value
is 0. Valid values are dependent upon the range selected in the range selection
field. If the value you entered is outside the normal operating range for the
output range selected, the module generates a configuration error.
For example, if you select engineering units for the ±10V dc range and enter a
fault value within the normal operating range (0 to 10000), the module will
configure and operate correctly. However, if you enter a value outside the
normal operating range (for example 11000), the module indicates a
configuration error.
1769-OF2 Program/Idle Value (Channel 0 and 1)
Use words 3 and 5 to set the integer values for the outputs to assume when the
system enters the program mode. The values are dependent upon the range
selected in the range selection field. If the value you entered is outside the
normal operating range for the output range selected, the module generates a
configuration error. The default value is 0.
