Diagnostics, Missing supply voltage L+
Enabling of the diagnostics for missing or insufficient supply voltage L+.
Channel activated
Specifies whether a digital output is activated or deactivated.
Reaction to CPU STOP
Determines the reaction of the digital output to CPU STOP or to failure of communication
between the interface module and CPU.
Substitute value
The substitute value is output by the module at CPU STOP if you set the "Reaction to CPU
STOP" parameter to "Substitute value".
Potential group
A potential group consists of a group of directly adjacent I/O modules within an ET 200SP
station HA, which are supplied via a common supply voltage.
A potential group begins with a light terminal block, via which the required supply voltage is
fed to all I/O modules of the potential group. The light-colored terminal block interrupts the self-
assembling voltage buses to the left neighbor
All other I/O modules of this potential group are plugged into dark terminal blocks. I/O modules
on dark terminal blocks take the potential of self-assembling voltage rail from the left neighbor.
A potential group ends with the dark terminal block, which follows a light terminal block or a
server module in the station configuration.
You can find additional information on the configuration of the potential group in the system
manual
SIMATIC; Distributed I/O System; ET 200SP HA.
