1.3 Function
1.3.1 General
Hardware The controller and analyzer module have a microprocessor with speci-
fic program parts of their own.
The controller and analyzer module communicate with one another via
a data bus. The processor in the controller controls the analyzer
module.
This involves the use of the CAN bus that is particularly suitable for
harsh environmental conditions.
The TresCon UNO is operated and programmed via the operating unit
of the controller.
Task distribution All the processes that are involved in the data exchange with the indi-
vidual components run in the background and have no significance for
the user.
1.3.2 Range of application/features
The analyzer is a continuously measuring precision analyzing system
for the control and optimization of biological waste water purification
processes. The instrument performs numerous monitoring tasks in
water/waste water treatment, especially within the sewage treatment
plant.
ATV specification M269 The TresCon UNO fulfills all the points of the guidelines specified in the
"Requirements of on-line process analysis instruments for N and P" in
the ATV specification, M269:

High availability of the systems to ensure continuous operation of
the wastewater treatment plant,

Fast response time of the analyzing instruments to changes in con-
centration to ensure efficient control,

Automatic calibration with minimum interruption of the measuring
operation.
Software Task
Controller Administration of all functions and parameters that
are independent of the type of the analyzer module,
e.g. recorder output, relay output, RS interfaces.
Analyzer
module Administration of all the functions and parameters
that involve the analyzer module, e.g. AutoCal para-
meters, AutoClean parameters.
