Data Communication; Figure 3-3 Data Communication Paths - Siemens Maxum II Manual

The original SYSCON consists of a single controller board. The newest version of SYSCON,
called SYSCON2, is a base SIB (SYSCON Interface Board) with an attached CAC3
(Communication and Control board). The SYSCON combines all data results and performs
additional high level data processing and calculations. The SYSCON connects to a color
touchscreen display, strip chart recorder, other analyzers, printers, the Advance
Communication System (ACS), or other connected networks.
The SYSCON is the analyzer control system in addition to containing the application database.
The application database also contains analytical hardware database definitions that are used
to perform the following functions:
● Obtain desired sampling measurements
● I/O and SNE schedule of timing events
● Sequence of sampling streams
