Saving the password If access control is enabled for the IQ S
administrator password is lost, quick administrator acces to the IQ S
ENSOR NET is not possible (access control: see section 5.4).
To avoid the loss of the password we recommend to create a back-up of the administrator password. This also applies to the use of the electronic key.
To be on the safe side, you can store the administrator password on an electronic key and/or note it on paper or a PC. Store the passwords in a safe place.

System 2020 XT USB Overview
Each main measured value occupies a sensor location in the IQ S
ENSOR NET. A double sensor with two active main measured
values thus occupies two sensor locations. The available sensor locations can be occupied by any single or double sensors.

1.2.4 Components of the system 2020 XT USB

Minimum configuration
(basic components)
IQ sensors, main and
secondary measured
values
The following basic components are required for a 2020 XT USB system:
An MIQ/TC 2020 XT, configured as controller
A power supply module (e.g. MIQ/PS)
At least one IQ sensor.
Sensors provide main measured values (e.g. pH, D. O. concentration, turbidity value...) and additionally, depending on the type, secondary measured values (e.g. temperature). In the System 2020 XT USB, digital YSI single sensors and double sensors can be used:
Single sensors provide a main measured value and normally a
secondary measured value (example: TriOxmatic 700 IQ
→ D. O. +
temperature).
All active 0/4-20 mA inputs of the MIQ/IC2 input module rank among
the single sensors. Via a 0/4-20 mA input, any external instruments can be connected to the IQ S
ENSOR NET via their current output.
Each input provides a main measured value.
Double sensors provide up to two main measured values and
normally a secondary measured value (example: VARiON 700 IQ
→ ammonium + nitrate + temperature).
Extension components The system can be adapted to fulfill different specifications by adding
further components, e.g. by:
Terminals. They are the operation and communication units for the
IQ S
ENSOR NET. Available are:
– MIQ/TC 2020 XT for operation of the system from various
locations, e.g. calibration of IQ sensors on site (compatible terminals, see section 1.4)
– MIQ/T2020 PC software terminals. The connection to the PC can
be established with the MIQ/IF232 interface module and the RS 232 interface of the PC or a remote connection with a modem (set for radio transmission, see chapter 10).
Output modules with relay, current and valve outputs. Valve outputs
enable the time controlled, compressed air operated cleaning of the sensor.

Overview System 2020 XT USB
Each current output, relay output and valve output occupies an output channel in the IQ S
ENSOR NET. The available output
channels can be assigned to outputs arbitrarily.

Connecting
MIQ modules
There are two basic mounting variants for connecting the MIQ modules:
Stack mounting - permanent mechanical and
electrical connection. The housings of the MIQ modules are permanently mounted on one another to form a stack. No cabling is necessary.
Distributed mounting - electrical connection via cable.
Locally separated MIQ modules or module stacks are connected with one another via the SNCIQ or SNCIQ/UG cable.
The following diagram shows an IQ S
ENSOR NET system with two
mounting variants (Fig. 1-3).
Fig. 1-3 Example of an IQ SENSOR NET system configuration
IQ sensors Up to 20 IQ sensors of any type can be used in the system
2020 XT USB. They can be connected to any MIQ module that has a free connection for the IQ S
ENSOR NET. The connection between the
IQ sensor and MIQ module is made via the SACIQ sensor connection cable. The IQ sensor connection cable is connected with the plug head connector of the IQ sensor via a screwable socket to form a watertight connection. As a result, the IQ sensor can be quickly removed for maintenance activities and then connected again.

1.2.5 MIQ modules

Some of the IQ S
ENSOR NET components are so-called MIQ modules
with different functions.
All MIQ modules have a standard housing with the following features (Fig. 1-4):
1 - 10
Fig. 1-4 MIQ module
1 Housing
2 Lid
3 Hinge
4 Contacts for voltage and communication
5 Contacts for the local identity function
6 Voltage LEDs
7 Terminal strip (example)
System 2020 XT USB Overview
Common characteristics
of the MIQ modules
Module lid with hinge
Due to its wide opening angle, the lid provides a large space for working inside the module (e.g. for connecting lines to the terminal strip).
Docking facility
MIQ modules can be mechanically docked onto one another. As a result, several MIQ modules can be mounted in the form of a stack to create a single unit (stack mounting). At the same time, docking enables the MIQ modules to be electrically connected with one another via the module contacts on the front and back so that no cabling is required. Even when it is part of a stack, each MIQ module can be opened. In addition, a terminal component can be docked onto each free lid front.
Terminal strip
Further IQ S
ENSOR NET components can be connected by cable to
the terminal strip inside the housing (distributed mounting). The terminal strip enables IQ sensors to be connected via the SACIQ sensor connection cable or the IQ S
ENSOR NET can be further
branched and extended here. Certain MIQ modules have a terminal strip with further specific connections (e.g. power connection, relay contacts, current outputs).
Local identity function
The local identity function is integrated in each MIQ module in the form of a memory chip. This memory chip can store information such as the designation of the measurement location and a specific selection of IQ sensors for the measured value display. This information is output when a terminal is docked and, thus, e.g. enables the rapid finding of local IQ sensors for calibration.
Voltage diagnosis via LEDs
Two LEDs, yellow and red, on the side of the housing are used to monitor the operational voltage of each MIQ module.

1.3.1 Operation as terminal/controller

When configured as a controller, the MIQ/TC 2020 XT is a basic component of the 2020 XT USB system and must therefore permanently remain in the system.
The MIQ/TC 2020 XT is connected to the system by docking on the free front cover of an MIQ module.
The controller function takes over the following tasks:
Control and monitoring of all IQ sensors
Control and monitoring of all current and relay outputs
Continuous diagnosis of the system, i.e. recording the information
and error messages of all modules and entering them in the system log book (e.g.: voltage monitoring)
Recording measured data in the fixed interval
Communication with external digital interfaces such as
– USB memory device
– Modem
– PROFIBUS, Modbus, RS485
–PC
1 - 13
Overview System 2020 XT USB
A terminal is required to display and set up the functions of the controller. The following terminal components are suitable:
MIQ/TC 2020 XT configured as terminal/controller or as terminal
(compatible terminals, see section 1.4)
MIQ/T2020 PC
(with MIQ/IF232 interface module, PC, modem connection or PROFIBUS environment).
The present component operating manual of the IQ S
ENSOR NET
System 2020 XT USB includes all functions of the MIQ/TC 2020 XT. The connection to Profibus or Modbus is established with the MIQ/(A-)PR and MIQ/(A-)MOD extension modules.

1.3.2 Operation as a terminal

The MIQ/TC 2020 XT configured as a terminal is an extension component for the IQ S
ENSOR NET System. The MIQ/TC 2020 XT can
be used as a mobile control unit and docked on and removed from all free front covers of MIQ modules. The docking is simply done by hand, without using any tools.
The terminal function is the graphical user interface of the system. It is used for the following purposes:
Display of measured values
Setting of IQ sensors, outputs, terminal characteristics, date, time,
etc.
Execution of maintenance and calibration work
Display of calibration data
1 - 14
Display of components lists (IQ sensors and outputs)
Display of the log book entries
If the MIQ/TC 2020 XT is registered in the system as a terminal, it is mobile and can be removed at any time. If the main controller of the system fails, the MIQ/TC 2020 XT automatically assumes the job of the failed controller (see section 1.3.3).
System 2020 XT USB Overview

1.3.3 Operation as backup controller

Automatic backup
function
If the MIQ/TC 2020 XT is configured as a terminal, it has a backup controller that assumes the basic functions of the IQ S
ENSOR NET
controller in the case of its failure. Thus the operating safety of the system is considerably increased. For these purposes the MIQ/ TC 2020 XT regularly and automatically saves the system configuration during the normal terminal operation.
System configuration The system configuration incudes the following allocations and
settings:
Settings of sensors and diff. sensors
Settings of outputs and links
Edit list of sensors
Edit list of outputs
Measured value recording (datalogger settings)
List of all components including software versions but without
terminal information.
Application-related sensor calibration (e.g. matrix adjustment)
In the IQ S
ENSOR NET, the system configuration is stored in the
controller (MIQ/TC 2020 XT).

This is achieved by
The two-wire connection technique that is not interference-prone
The digital signal transmission resulting from this
Tools for error diagnosis
– LEDs on the MIQ modules to check the available voltage
– Log book messages with instructions to eliminate problems
The possibility to simply assign substitute components for
components to be exchanged. Replacing components is simple and can be performed very quickly (see section 7.4). The system configuration (Settings of sensors and diff. sensors and Settings of outputs and links) and the measured data are stored in the controller and remain stored when other components are used.

Overview System 2020 XT USB
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.
