Understanding Configurable FLEX Ex Analog Module Features 2-9
Analog Fault State
The Analog Fault State feature determines how your I/O module reacts to
faults when a channel is used in analog mode. After a fault condition occurs,
the module may got to minimum value, maximum value, hold last state or 50%
of range.
Use your programming software to set the Analog Fault State bits on the
I/O module for one of the following fault reactions:
• 0 = minimum value
• 1 = maximum value
• 2 = hold last state
• 3 = 50% of range
You can set these parameters independently for channels 0-1, 2-3, 4-5, 6-7.
Digital Fault State
The Digital Fault State feature determines how your I/O module reacts to
faults when a channel is used in digital mode. After a fault condition occurs,
the module may reset channel outputs or hold last state of the outputs.
Use your programming software to set the Digital Fault State bit to 0 to reset
outputs. Set to 1 to hold last state of the outputs after a fault occurs. This
feature is available on a per channel basis.
