Channel Activated; Reaction To Cpu Stop; Substitute Value; Potential Group - Siemens SIMATIC ET 200SP HA Equipment Manual

Parameters
6.3 Explanation of the module/channel parameters
6.3.7

Channel activated

Definition
Specifies whether a channel is activated or deactivated.
6.3.8

Reaction to CPU STOP

Definition
Specifies the behavior of the digital output as a reaction to CPU stop or to failure of
communication between the interface module and CPU.
6.3.9

Substitute value

Definition
The substitute value is output by the module at CPU STOP if you set the "Reaction to CPU STOP"
parameter to "Substitute value".
Description
The entered substitute value is output by the I/O module in the following cases:
• When there is no connection to the CPU (for example, PROFInet cable unplugged)
• With CPU STOP
6.3.10

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.
