Each DO/DI module can be switched by the user application program to Sleep Mode. In
Sleep Mode, the module does not function and the power consumption is minimized.
During Sleep mode, the user application program will get the KLV or PDV per each DI.
In the event of a DO/DI module failure, the ERR LED on the module will be lit. This
event is registered by the CPU in the Error Logger. DO/DI module failure status is also
visible to the user application program.
The DO/DI module can be diagnosed and monitored using the STS Hardware Test utility.
The Hardware Test verifies that the module is operational, presents the module
configuration and shows the actual value of each input and output. It is also possible to
change the input filter setup for the duration of the Hardware test and change the value of
the DOs.
In the Hardware Test utility, it is possible to set the module to Freeze Mode. In this mode
the user application program will get the KLV/PDV of each input in the module instead
of the actual input value. The DO values will keep the last value they had when the
module was switched to Freeze Mode. Freeze mode enables testing the inputs and outputs
while the user application program is running.
