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.
Description
Both redundant modules measure simultaneously and independently in the process. Both
redundant modules generate diagnostics, interrupts and process values.
