Sleep Mode
Each High Voltage 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 predefined values
(PDV) for each I/O.
Module Status and Diagnostics
In the event of High Voltage DI Module failure, the I/O module ERR LED will be lit. This
event is registered by the CPU in the Error Logger. DI Module failure status is also visible to
the user application program.
The High Voltage DI module can be diagnosed and monitored using the STS Hardware Test
utility. This test verifies that the module is operational, presents the module configuration and
shows the actual value of each input. It is also possible to change the input filter setup
temporarily for the duration of the Hardware Test.
In the Hardware Test utility, it is possible to set the High Voltage DI module to Freeze Mode.
In this mode the user application program will get the predefined value of each input in the
module, instead of the actual input value. Freeze mode enables testing the inputs while the user
application program is running.
For details on configuring the High Voltage DI modules, see the Site Configuration section,
and the Application Programming section of the STS User Guide.
