Publication 1769-UM002B-EN-P - July 2005
4-32 Module Data, Status, and Channel Configuration for the Output Modules
1769-OF8C and -OF8V 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-OF8C) or the
1 to 5V range (for 1769-OF8V), a configuration error
results.
• See Table 4.17 1769-OF8C Valid Output Data Table
on page 4-33 and Table 4.18 1769-OF8V Valid Output
Data Table on page 4-34 for more examples.
