Modular AS 410-5H and AS 410E systems
Flexible and scalable availability
A particular characteristic of the modular S7-400 systems is the
flexible and scalable availability of various components.
For a SIMATIC PCS 7 AS Single Station of the AS 410 type, you
have the option of specifically increasing the availability by im-
plementing a redundant configuration of the power supply or the
Industrial Ethernet communications module, and combining
these measures.
Even the AS Redundancy Station of the AS 410 type with its re-
dundant CPUs offers significantly higher availability. It operates
according to the 1oo2 principle, in which a switch is made from
the active subsystem to the standby system in the event of a
fault. Starting from here, you can double the power supply or the
Industrial Ethernet communications module for each subsystem,
and combine these measures.
