HIMax System 3 Product Description<br />
3 Product Description<br />
HIMax is a safety-related control <strong>system</strong> and is intended for continuous operation and<br />
maximum availability.<br />
HIMax is a modular <strong>system</strong>. Functions such as processing, input and output or communication<br />
are distributed on plug-in modules that can be inserted in one or several base plates. A<br />
controller specific to the application can be created by selecting appropriate modules.<br />
Ethernet cables are used to interconnect the base plates.<br />
The controller can be easily adapted to future extensions of the process to be controlled,<br />
e.g., by adding modules or base plates containing modules.<br />
Figure 1 shows the structure of the HIMax <strong>system</strong>. The figure shows the base plates, both<br />
<strong>system</strong> busses, the <strong>system</strong> bus modules, the processor modules and the Connector<br />
Boards of the modules.<br />
To increase availability, HIMax is intended for redundant operation. For more information,<br />
refer to Chapter 4.<br />
The <strong>system</strong> can also be used as mono, non-redundant <strong>system</strong>. For more information, refer<br />
to Chapter 3.3.2, Variant 1, and Appendix.<br />
In either case, safety-related operation up to SIL 3 is ensured.<br />
