Function 
If system modules are added to a gas analyzer, replaced (changed) or re-
moved, this modification must be configured in the software. 
Definition 
System modules are 
•  Analyzer modules: Uras26, Limas11 IR, Limas21 UV, Limas21 HW,   
Magnos206, Magnos28, Magnos27, Caldos25, Caldos27, Fidas24,   
Fidas24 NMHC, ZO23 
•  I/O modules: Profibus, Modbus, 2-way analog output, 4-way analog 
output, 4-way analog input, digital input/output 
•  External I/O devices: e.g. cooler I/O board. 
Analyzer modules and external I/O devices 
Analyzer modules and external I/O devices are connected to the system 
controller via the system bus. They must be identified by their serial number 
(see below) in order to be recognized by the gas analyzer. 
I/O modules 
The I/O modules are attached and directly connected to the system control-
ler board. They have no serial numbers. 
An I/O module is automatically recognized by the gas analyzer when it is 
added for the first time or as replacement for an already existing I/O mod-
ule.
