4-10 Module Data, Status, and Channel Configuration for the Output Modules
If this selection is enabled [the bit is set (1)] and the system enters the program
mode, it commands the module to convert the user-specified value from the
channel’s program/idle value word (3 or 5) to the appropriate analog output
for the range selected.
1769-OF2 Program/Idle to Fault Enable (PFE0 and PFE1)
If a system currently in program/idle mode faults, this setting (word 0, bit 0;
word 1, bit 0) determines whether the program/idle or fault mode value is
applied to the output. If the selection is enabled [the bit is set (1)], the module
applies the fault mode data value. If the selection is disabled [the bit is reset
(0)], the module applies the program/idle mode data value. The default setting
is disabled.
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 the program/idle value
in either a 1 to 5V dc or 4 to 20 mA range, a
configuration error results.
• See Table 4.5 1769-OF2 Valid Output Data Table on
page 4-12 for more examples.
