If the device is retrofitted with an option module 2.1, this must be activated via LUI or PDM.
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.
