4-16 Module Data, Status, and Channel Configuration for the Output Modules

1769-OF4CI and -OF4VI Program/Idle Value

Use each channel’s Program/Idle Mode word 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.

For example, if you select engineering units for the 0 to 20 mA range and enter
a program/idle value within the normal operating range (0 to 20000), the
module will configure and operate correctly. However, if you enter a value
outside the normal operating range (for example 21000), the module indicates
a configuration error.

TIP

Not all controllers support this function. Refer to your
controller’s user manual for details.

EXAMPLE

 If the default value, 0000, is used and the range selected

is 0 to 20 mA, the module will output 0 mA for all data
formats.

 If the raw/proportional or engineering units format is

selected and zero is entered as Program/Idle mode
word in the 4 to 20 mA range (for 1769-OF4CI) or the
1 to 5V range (for 1769-OF4VI), a configuration error
results.
