Preventive actions to
optimize the availability
of the system
If the requirements of the availability are especially high, you can
further improve the availability of the system as follows:
 Install identical components in the system.
If the requirements of the availability are high, components can be
installed doubly in the system (exception: controller component).
 Back up the controller function with the aid of a second MIQ/
TC 2020 XT configured as a terminal.
The MIQ/TC 2020 XT has a redundant controller function. It
maintains all essential functions of the system in the case of a
controller malfunction and saves all settings. The controller
operation starts automatically.
 Keep substitute components ready.
The system automatically recognizes substitute components of
active components (IQ sensors and the output modules). They are
easily integrated in the system by assigning them as substitute
components.
 Save the system configuration.
The system configuration (Settings of sensors and diff. sensors and
Settings of outputs and links) can be saved on a PC. Transmission
takes place via the USB interface (alternative options: see section
1.2.3). The stored system configuration can be loaded from the PC
on a substitute controller if necessary.
