1.3 MIQ/T2020 PLUS controller operation
Automatic safety
function The MIQ/T2020 PLUS has a controller that takes over the basic functions of the IQ SENSOR NET controller if it fails and thus
considerably increases the operational safety of the system. For this
purpose, the MIQ/T2020 PLUS automatically and regularly saves the
system configuration during the regular terminal operation.
System configuration Thesystemconfigurationcontainstheallocationofthesensornumbers
and all settings of the following menus:
lSettings of sensors and diff. sensors
lSettings of outputs and links
lEdit list of sensors
lEdit list of outputs
lMeasured value recording (datalogger settings).
In the IQ SENSOR NET, the system configuration is saved in the
controller (MIQ/C184 or MIQ/MC).
Functions in the MIQ/
T2020 PLUS controller
operation
The MIQ/T2020 PLUS controller operation comprises all basic
functions of the IQ SENSOR NET. Relay and current interfaces work
without restrictions.
Restrictions in the MIQ/
T2020 PLUS controller
operation
In the MIQ/T2020 PLUS controller operation, the following functions
cannot be supported:
lEditing the system configuration. Apart from date and time, all
settings in the Settings menu are locked and cannot be released for
changing
lAdding new sensors and input or output modules
lContinuing the datalogger operation of the main controller
lContinuing the Profibus, Modbus, or modem communication of the
main controller (due to missing interfaces).
A redundant data logging function can be set up with the aid of the
MIQ/IF232 interface module.
Manual saving function Apart from automatically saving the system configuration, the system
configuration can be saved manually in the MIQ/T2020 PLUS at any
timeduringregularterminaloperation.Thisfunctioncanbeusedforthe
MIQ/T2020 PLUS controller operation and for the following tasks as
well:
lMaking a safety copy of the system configuration, for example
before changing settings that may have to be undone again (testing
new settings).
lTransmitting the system configuration to a second IQ SENSOR NET
system. This facilitates the quick commissioning of several similar
systems.

3.2 Commissioning
Note
Follow the installation instructions in the INSTALLATION chapter of the
system operating manual.
Up to three terminalcomponents can be docked on an IQ SENSOR NET
system.
3.2.1 Software requirements
The MIQ/T2020 PLUS requires for its operation an IQ SENSOR NET
main controller with the software version 2.04 or higher. Full
functionality is available when using a main controller with the software
version 2.70 or higher. Using older main controller versions there are
small functional restrictions when retransferring the storedsettings (for
details, see section 4.3.3).
3.2.2 Docking and removing a terminal
The mobile MIQ/T2020 PLUS terminal is docked on the lid of any free
MIQ module. The terminal can be docked while the system is running
without the measurement being interrupted.

Note
For the temporary docking of a mobile terminal, do not remove the
whole contact cover. Leave it hanging on the side of the MIQ module.
After removing the terminal, replace the cover again to protect the
contacts.
Fig. 3-2 Docking the terminal
Removing the terminal To remove the terminal, press the locking lever and pull the terminal
forwards.
1Pull the cover off the contacts (pos. 1 in Fig. 3-1) on the lid of
the MIQ module.
2Place the terminal on the module lid. To do so, insert the flap
on the back of the terminalinto the slot on thedoor hinge ofthe
module. Then, pull back the interlocking lever (pos. 2 in
Fig. 3-2), place the terminal completely on the module and
release the interlocking lever.

3.2.3 Initialization
When the system is running, the terminal automatically starts to
operate as soon as contactis established to the IQ SENSOR NET. In the
first phase, the background illumination of the display switches on and
the terminal is initialized. This process may last a few seconds. The
following display appears (Fig. 3-3):
