Note
Ongoing pulse stretching is reset when an error occurs in the value status (QI = 0, for example
wire break).
Inversion
Specifies whether or not the input signal is to be inverted.
Inversion can be used with the following encoder types:
● NAMUR sensor
● Single contact, unconnected
● Single contact with 10 kΩ
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 block section take the potentials of self-assembling voltage rails 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
