2.4 Communications
All of the gas analyzers in Series 6, ULTRAMAT
6, OXYMAT 6/ 61, CALOMAT 6, ULTRAMAT 23
and also FIDAMAT 6 provide the following
communication methods:
•
ELAN interface (also with SIPROM GA)
•
PROFIBUS DP / PA
•
AK interface
ELAN interface
ELAN is a serial interface (RS 485) built in as
standard and which allows communication
between several analyzers. A maximum of 12
analyzers with no more than four components
may be networked together. Connection can be
made even without a PC.
The following diagram shows how this works.
