2.2 Designs and Types of the PES
The controls can be adapted to the requirements of the plant by equipping them with the ap-
propriate central modules. The following structures are possible with the H41q or H51q system
family:
* Central modules, communication modules and I/O modules are installed in the system sub-
rack.

Notes:
Mono = single channel system structure
Redundant = redundant central modules and/or separated I/O bus system structure
SIL = Safety Integrity Level according to IEC 61508
I/O = input and output
