3.2 Explanation of the parameters

3.2 Explanation of the parameters
Group diagnostics: No supply voltage L+
When you enable this parameter, the ET 200SP generates one diagnostic per potential
group (as group information) when the supply voltage L+ fails.
This function does not depend on enabling the parameter "Diagnostics: No supply voltage
L+" of the I/O modules.
The diagnostics is formed from the states of the supply voltage of the installed I/O modules
within the potential group.
Requirements
● All I/O modules must be inserted, i.e. the current configuration must not have any empty
slots.
● If no I/O modules are inserted on light-colored BaseUnits BU..D, the beginning of this
potential group is not recognized. The I/O modules of this potential group are therefore
part of the previous potential group.
If the I/O module is installed on the light-colored BaseUnit, the potential group is
detected, the diagnostics is reevaluated according to the potential group arrangement
and new diagnostics may be reported. The position of the light-colored BaseUnit remains
stored in the structure until the supply voltage 1L+ of the CPU/interface module is turned
off.
3.3

Address space

Introduction
You can read out the status of the supply voltage L+ and the feedback voltage of I/O
modules via the address space of the server module:
● All I/O modules:
No supply voltage L+ or no I/O module available
● Additional digital output module HF:
feedback voltage present
Requirements
● The I/O module used must support monitoring of the supply voltage.
● The I/O module used must support monitoring of a feedback voltage.
