Description
4.7 Option modules
Option module 2.1
The option module 2.1 (OM2.1) is a "passive" module whose control is handled by the
relevant analyzer module. For every component measured by the analyzer module, the
OM2.1 makes an analog output available. This option module also provides three digital
outputs per analyzer module with a fixed function assignment.
Option module 2.2
Option module 2.2 (OM2.2) is a system module connected directly via the CAN bus. Just like
the analyzer modules, this module is an "intelligent" module with the following core
properties:
● Independent identification in the menu of the LUI
● Plug & measure capability
● Parameter assignment including parameter block transfer (save and restore)
● Diagnostics and test functions
● Inclusion in the logbook
● Download of firmware and parameter blocks
Compared to option module 2.1, the option module 2.2 provides four analog inputs and four
digital inputs. The additional analog inputs can be used as measured value source for the
correction of cross-interference and/or pressure compensation. You can also output the
analog input measured values in the display of the additional process values (main view).
Test mode can be activated for analog as well as digital inputs.
