Module Operating Features All features of the 1794-OF8IH analog output module are independently
configurable.
Local Fault Mode
The Local Fault Mode can be programmed to determine how the module
responds to communications faults and internal module faults.
When setting the Local Fault Mode feature in your programming software, set
this feature’s bit to 0 to use the analog fault state or digital fault state only if a
communications fault occurs. Set the bit to 1 to use the Analog Fault state or
Digital Fault state if any fault occurs.
