Explanation of parameters

Diagnostics, Missing supply voltage L+
Defines whether a diagnostic interrupt is generated when the supply voltage L+ is missing or is
too low.
Potential group
An Ex module group consists of the associated Ex power module and a group of Ex I/O modules
placed directly adjacent to one another, which are supplied by the Ex power module via the
power bus.
An Ex module group begins with an Ex power module, via which the required voltage for all Ex
I/O modules of the potential group is supplied.
An Ex module group ends when an Ex power module or a server module in the station
configuration follows an Ex BaseUnit.
Additional information
You can find information on the configuration of potential groups in the basic assembly of the
I/O station in the respective system manual for the distributed I/O system.
