Potential group
Definition
A potential group consists of a group of directly adjacent I/O modules within an ET 200SP HA
station that are supplied via a common supply voltage.
Description
A potential group is built up from left to right by using terminal blocks.
A new potential group starts on the left side with a light gray terminal block, via which the supply
voltage for the potential group is fed in.
The potential group is continued to the right with dark gray terminal blocks and ends when a
new potential group is built up next to it.
The potential group also ends if there is a black terminal block next to it. Black terminal blocks
are fed individually and cannot be included in potential groups.
You can find additional information on the configuration of the potential group in the system
manual SIMATIC; Distributed I/O System; ET 200SP HA.
