Sleep Mode
Each DO module can be switched by the user program to Sleep Mode. In Sleep Mode, the
module is not functioning and the power consumption is minimized.
Module Status and Diagnostics
In the event of module failure, the module’s ERR LED will be lit. This event is registered by
the CPU in the Error Logger. Module failure status is also visible to the user program.
The DO 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 output. It is also possible to change the DO’s value.
In the Hardware Test utility, it is possible to set the module to Freeze Mode. In this mode, the
DOs will keep the last value they had at the time they were frozen. Freeze mode enables
testing the inputs and outputs while the user program is running.
For details on configuring the DO modules, see the Configuring a Site section and the
Application Programmer section of the ACE3600 STS User Guide.
