11.3.5 Output operations of the digital output module

When an error occurs, such as ladder operations not being possible on the CPU module or disconnection of
the remote I/O line of the PI/O unit, the state of the output of the digital output module installed in each unit
becomes RESET or HOLD depending on what was set in 9.3.3 Output hold setting for digital output modules.
If RESET is set, output is turned off. If HOLD is set, the output from immediately before the error occurred is
held.
Note: The output hold setting is valid only for the digital output module.
It is not valid for the analog output module, which always operates with an output hold.
