6.3 Explanation of the module/channel parameters
6.3.1

Diagnostics, Missing supply voltage L+

Definition
Enabling of the diagnostics for missing or insufficient supply voltage L+.
6.3.2

IO redundancy

Definition
You can configure two identical modules redundantly. To do so, plug both modules into a
redundant terminal block side by side. You can find additional information on mounting
modules in an IO redundancy configuration in the ET 200SP HA System Manual, section
"Installing", "Installing terminal block".
In IO redundancy mode, the left module is the master and the right module is the slave. The
HART communication takes place exclusively via one of the two redundant channels.
