3.1 Connecting the communication interfaces
Installation and wiring is described in the Operating Instructions of
Liquiline Control CDC90.
3.1.1 Notes
The device starts when the supply voltage is applied. This process can take up to two
minutes, depending on the device configuration. Communication with the device is not
possible during the start-up process.

1 Analog output in BASE2-E
2 Analog input 2AI
3 Process control system, PCS
1) The second analog output in BASE2-E is used to monitor and receive feedback from the
CDC90.
2) The second analog input (2AI module) is used to send specific current values in mA.
Connecting analog communication
1. Unscrew the housing from the CDC90 control unit. See Operating Instructions
BA01707C.
2. Connect a 2-wire cable from the analog output AI of the control system (3) to the
analog input of the 2AI module (2) in the CDC90 control unit.
3. Connect a 2-wire cable from the analog input AI of the control system (3) to the
analog input of the BASE2-E module (1) in the CDC90 control unit.
Current input 4:1 are internal for the soft keys and
Current output 1:1 for the status of the LEDs. These settings must not be changed.
For more details on analog input and output characteristics of the CM44x transmitter,
please refer to the Operating Instructions of the CM44x (BA00451C).

4 System integration
The internal analog input of the CDC90 control unit is used to send commands to the
CDC90. Conversely, the analog output of the CDC90 control unit is used to receive analog
feedback signals from the CDC90.
4.1 Integrating analog communication into the system
4.1.1 Configuration of the CDC90 control unit
The settings of the CDC90 control unit are preconfigured. So that the configuration can be
reviewed and changed, the configuration is described as follows.
1. Adjust the settings via the remote display or web server access.
2. For web server access, enter 192.168.0.4 as the IP address.
See under Menu/Setup/Inputs/Current input 4:1; these values are reserved for the soft
keys of the CDC90 control unit and must not be changed.
See under Menu/Setup/Inputs/Current input 4:2; this current input is linked internally
to the Liquiline Control CDC90 via Modbus TCP. The configuration of the Modbus AI must
not be changed.
See under Menu/Setup/Outputs/Current output 1:1 ; these values are reserved for the
LED display of the CDC90 control unit and must not be changed.
The configuration of the Modbus AO must not be changed under Menu/Setup/Outputs/
Current output 1:2. The Current output 1:2 is linked internally to the Liquiline Control
CDC90 via Modbus TCP.
4.1.2 Configuration in Liquiline Control CDC90
A0041805
To start remote control of the CDC90, the CDC90 must be set to the Remote access mode.
It is possible to read the CDC90 parameters in any mode.
1. In the CDC90, go to Application/Communication.
2. Select Analog.
3. Press Accept to confirm.
Only fieldbus communication or analog communication is used to send commands to
the Liquiline Control CDC90 or to read the values.

 2 Programs
Each program must be selected before starting. An example of controlling program 801:
1. Set AI to 4 mA.
 Initialization in progress.
2. Wait for confirmation AO equal to 4 mA.
3. Set AI to 11 mA.
 Program selection in progress.
4. Wait for confirmation AO equal to 11 mA.
5. Set AI to 5 mA.
 Program starts.
After the program starts, the analog output outputs 5 mA as long as the program is
running. When the program is finished, the analog output outputs 9 mA.
With short programs (e.g. valve travel), the AO may output 9mA.
After quitting a program successfully, a new program can be selected and started
immediately.
If the program is stopped or is aborted due to an error:
1. First initialize the system by sending 4 mA.
2. Select and start a new program.
With analog communication, only the first 10 programs are controlled.
