environments and boosting product output and quality.
Liquiline Control CDC90 can be easily integrated into existing plant infrastructures and enables thepractical remote operation of your measuring points via the control station.

Measuring system

A complete measuring system comprises the following components:• Liquiline Control CDC90• Retractable assembly (e.g. Cleanfit series)• pH/ORP sensor• Lines for compressed air, water and electrics• Digital measuring cable

Pumps

You can choose from the following cleaning and calibration options:
Predefined program for:• Cleaning the sensor• Cleaning and calibrating the sensor• Assembly retraction in measuring and service position• User-definable programs without predefined program steps
You can freely configure all programs to suit your requirements. The predefined programs are used
for faster configuration.

Calibration andmeasurement

Calibration options for pH glass, ISFET and ORP sensors:• Single-point or two-point calibration
The buffer tables e.g. according to DIN, Endress+Hauser etc. are saved by setting the buffers used
and automatically calculating the pH values depending on the temperature.
• Automatic acceptance of calibration data for digital sensors with Memosens technology

Equipment architecture

Inputs and outputs
The CDC90 control unit consists of a Liquiline transmitter and a separate industrial PC (IPC).
The Liquiline transmitter acts as the peripheral interface for analog and digital signals. These arecontrolled by an IPC that has a separate software program for the automation of the measuring
point.

4

Endress+Hauser

Liquiline Control CDC90

The IPC is responsible for retracting the assembly and activating the pilot valve manifold, andprocesses all the states of the float switches and pressure switches.
The IPC only establishes digital fieldbus communication to the control station.
In both the IPC and the Liquiline transmitter, operation and configuration is possible via the device's
web server.
Primary operation is via the IPC. As the Liquiline transmitter is preconfigured upon delivery, it
generally does not require any further configuration.
The assignment of the inputs and outputs is provided in the following table and graphic:

Communication and dataprocessing

Types of communication
Several digital communication protocols are available to enable the Liquiline Control CDC90 to be
integrated into a customer's digital infrastructure (process control system).
The data connection is established and managed exclusively via the internal controller of the CDC90,
and not via the fieldbus module of the integrated Liquiline transmitter.
Additional Special Documentation is available for the integration process. However, if analog signals
are used (current inputs/outputs), the current input and output modules of the Liquiline transmitter
act as the interface to the customer's control system / PCS. Output 1:2 on the base module and input
4:2 on the AI module are preconfigured. Only the current outputs on the 4 AO module need to be
configured for measured value transmission.
Liquiline Control CDC90 has an internal communication process via Modbus, which is designed
exclusively to ensure safe and reliable processing and the trouble-free operation of the device. These
communication processes are not designed for external communication with the customer.
Therefore, with the exception of the Liquiline transmitter's web server functionality, do not connect
the interfaces of the transmitter to other interfaces.
You can choose from the following communication options in the CDC90 control unit:• Analog current output, current signals (4 to 20 mA)
Via AO modules in the CDC90 control unit. The settings can be made via the web server or local
display.
Power transmission is via the current input/output modules of the CDC90 control unit. The input/
outputs are already preconfigured.
• EtherNet/IP (adapter)• PROFIBUS DP (slave)• Modbus TCP (server)• PROFINET (device)
More detailed information on fieldbus communication is provided on the product pages on theInternet:• EtherNet/IP (adapter) via Modbus TCP - EtherNet/IP gateway: BA02241C• Modbus TCP (server): BA02238C• PROFIBUS DP (slave) via Modbus TCP - PROFIBUS DP gateway. BA02239C• PROFINET (device) via Modbus TCP - PROFINET gateway: BA02240C

Dependability

Reliability• Level and consumption indicator
The level and amount of buffer or cleaning solution are displayed.
• Information about the current program step
Transparent status indication with time information• Sensor verification
Sensor accuracy is verified. If a tolerance range is exceeded during calibration, Liquiline Control
rejects the calibration values. Therefore you are guaranteed that your measured value is always
accurate.
• Seal condition monitoring
Monitoring of the seals on the assembly, pumps, water valve and additional valves. With thisfunction, the system can predict when the assembly will require new sealing rings.
• System pressure monitoring to activate the assembly and pumps. If the pressure drops below theminimum level, the system signals an alarm.
Memosens
Memosens makes your measuring point safer and more reliable:• Non-contact, digital signal transmission enables optimum galvanic isolation• Completely watertight• Sensor can be calibrated in a lab, thus increasing the availability of the measuring point in theprocess• Maintenance thanks to recording of sensor data, e.g.:

Modbus TCPNOTICEThe device uses an EtherCat connection for internal communication. Depending on the network
load, EtherCAT may cause failures in the CDC90 IPCs if multiple CDC90 devices are integrated
in the same network.
‣ To reduce the network load in the case of a Modbus TCP connection, the networks must be
separated. Physical separation with a VLAN-enabled switch, e.g. Layer 2 managed switch, orsoftware-based separation is possible.
