Device architecture

Order of the modules

Basic rule for hardware upgrades

 3 Slot and port assignment of the hardware modules

• Inputs are assigned to measuring channels in the
ascending order of the slots and ports.
Adjacent example:
"CH1: 1:1 pH glass" means:
Channel 1 (CH1) is slot 1 (basic module) : Port 1 (input

1), pH glass sensor

• Outputs and relays are named according to their
function, e.g. "current output", and are displayed in
ascending order with the slot and port numbers

 4 Slot and port assignment on the

display

Depending on the version ordered, the device is supplied with a number of electronic modules, which
are assigned in a specific sequence in ascending order to slots 0 to 7. If you do not have a particular
module, the next moves up automatically:

• The basic module (which is always present) always occupies slots 0 and 1

• Fieldbus module 485

• Memosens input module 2DS (DS = digital sensor)

• Extension module for digital inputs and outputs DIO (DIO = digital input and output)

• Current input module 2AI (AI = analog input)

• Current output module 4AO or 2AO (AO = analog output)

• Relay modules AOR, 4R or 2R (AOR = analog output + relay, R = relay)
Modules with 4 ports are connected before modules of the same type with 2 ports.

Please note the following if upgrading the device:

• The sum of all current inputs and outputs may not exceed 8!

• A maximum of two "DIO" modules may be used.

Determining the hardware delivery status

You must be aware of the type of modules and the number of them supplied with the device you
have ordered to determine the delivery status of your Liquiline.

• Basic module
One basic module in all versions. Always occupies slots 0 and 1.

• Fieldbus module
Optional, and only one fieldbus module is possible.

• Input modules

• Must be clearly assigned to the number of optional inputs ordered.

• Examples:

2 current inputs = module 2AI
4 Memosens inputs = 2 inputs with basic module + module 2DS with 2 further inputs

• Current outputs and relays
Various module combinations can exist.
The following table will help you determine which modules your device has, depending on the type
and number of outputs.

Relays

Current outputs

2 - 1 x 2R 1 x 4R

4 1 x 2AO 1 x AOR 1 x 2AO + 1 x 4R

6 1 x 4AO 1 x 4AO + 1 x 2R 1 x 4AO + 1 x 4R

8 1 x 4AO + 1 x 2AO 1 x 4AO + 1 x 2AO + 1 x 2R 1 x 4AO + 1x 2AO + 1 x 4R

Sum up the number of modules and sort them according to the specified sequence →  6.

‣

0 2 4

 This will give you the slot assignment for your device.

Terminal diagram

The unique terminal name is derived from:

Slot no. : Port no. : Terminal

Communication and data processing

Communication protocols:

Fieldbus systems

• HART

• PROFIBUS DP (Profile 3.02)

• Modbus TCP or RS485

• PROFINET

• Ethernet/IP
Only one type of Fieldbus communication can ever be active. The last activation code entered

decides which bus is used.

The device drivers available make it possible to perform a basic setup and display measured
values and diagnostics information via the fieldbus. A full device configuration via the fieldbus
is not possible.

Extension module 485 and current outputs

For PROFIBUS DP, and Modbus RS485 communication protocols:

• CM442R

Current outputs cannot be used in parallel. Any existing current outputs are deactivated with the
installation of 485.

• CM444R/CM448R

A maximum of 2 current outputs can be used in parallel.

Ethernet functionality via Base2 module and current outputs

• CM442R

A maximum of 2 current outputs can be used in parallel.

• CM444R and CM448R

A maximum of 6 current outputs can be used in parallel.

Bus termination on the device

• Via slide switch at bus module 485

• Displayed via LED "T" on bus module 485

Reliability

Dependability

Memosens

Memosens makes your measuring point safer and more reliable:

• Non-contact, digital signal transmission enables optimum galvanic isolation

• No contact corrosion

• Completely watertight

• Sensor can be calibrated in a lab, thus increasing the availability of the measuring point in the

process

• Intrinsically safe electronics mean operation in hazardous areas is not a problem.

• Predictive maintenance thanks to recording of sensor data, e.g.:

• Total hours of operation

• Hours of operation with very high or very low measured values

• Hours of operation at high temperatures

• Number of steam sterilizations

• Sensor condition

Heartbeat diagnostics

• Heartbeat diagnostics screen with graphic indicators for the health of the device and sensor and

with a maintenance or (sensor-dependent) calibration timer

• Heartbeat status information on the health of the device and the condition of the sensor

: Sensor/device condition or maintenance timer > 20 %; no action is required

•

• : Sensor/device condition or maintenance timer > 5 ≤ 20 %, maintenance not yet urgent but
should be scheduled

• : Sensor/device condition or maintenance timer < 5 %, maintenance is recommended

• The Heartbeat sensor condition is the assessment of the calibration results and the sensor
diagnostic functions.

14 Endress+Hauser

Liquiline CM442R/CM444R/CM448R

An unhappy smiley can be due to the calibration result, the measured value status or to the
operating hours limit having been exceeded. These limits can be configured in the sensor setup in a
way that adapts the Heartbeat diagnostics to the application.

Heartbeat and NAMUR category

The Heartbeat status indicates the sensor or device condition while the NAMUR categories (F, C, M,
S) assess the reliability of the measured value. The two conditions can correlate but do not have to.

• Example 1

• The number of remaining cleaning cycles for the sensor reaches 20% of the defined maximum
number. The Heartbeat symbol changes from
NAMUR status signal does not change.

• If the maximum number of cleaning cycles is exceeded, the Heartbeat symbol changes from
to . While the measured value can still be reliable, the NAMUR status signal changes to M
(maintenance required).

• Example 2
The sensor breaks. The Heartbeat status changes immediately from
status signal also changes immediately to F (failure).

Heartbeat Monitoring

Sensor data from Memosens sensors are transmitted via the EtherNet/IP, PROFINET, PROFIBUS DP,
HART, Modbus RTU and Modbus TCP fieldbus protocols. These data can be used for predictive
maintenance, for instance.

Examples include:

• Total hours of operation

• Hours of operation with very high or very low measured values

• Hours of operation at high temperatures

• Number of steam sterilizations

• Sensor identification

• Calibration information

Heartbeat Verification

Heartbeat Verification makes it possible to verify the correct operation of the measuring device
without interrupting the process. This verification can be documented anytime.

Sensor Check System (SCS)

The Sensor Check System (SCS) monitors the high impedance of the pH glass. An alarm is issued if a
minimum impedance value is undershot or a maximum impedance is exceeded.

• Glass breakage is the main reason for a drop in high impedance values

• The reasons for increasing impedance values include:

• Dry sensor

• Worn pH glass membrane

For the SCS, upper and lower limit values can be enabled or disabled independently of one
another.

Process Check System (PCS)

The process check system (PCS) checks the measuring signal for stagnation. An alarm is triggered if
the measuring signal does not change over a specific period (several measured values).

The main causes of stagnating measured values are:

• Contaminated sensor, or sensor outside of medium

• Sensor defective

• Process error (e.g. through control system)

Self-monitoring functions

Current inputs are deactivated in the event of overcurrent and reactivated once the overcurrent
stops. Board voltages are monitored and the board temperature is also measured.

USP and EP

The limit functions for pharmaceutical water in accordance with USP and EP specifications are
implemented in the software for conductivity measurements:

• "Water for Injection" (WFI) as per USP <645> and EP

• "Highly Purified Water" (HPW) as per EP

• "Purified Water" (PW) as per EP
The uncompensated conductivity value and the temperature are measured for the USP/EP limit

functions. The measured values are compared against the tables defined in the standards. An alarm
is triggered if the limit value is exceeded. Furthermore, it is also possible to configure an early
warning alarm that signals undesired operating states before they occur.

ChemocleanPlus

Freely programmable sequence control

• e.g. for automatic sensor cleaning in retractable assemblies for reliable measurement results in
processes with a high risk of contamination

• Individual, time-based activation of 4 outputs e.g. relays

• Starting, stopping or pausing of activities via digital input or fieldbus signals e.g. from limit
position switches

Maintainability Modular design

The modular transmitter design means it can be easily adapted to suit your needs:

• Retrofit extension modules for new or extended range of functions, e.g. current outputs, relays and
digital communication

• Upgrade to maximum eight-channel measurement

• Optional: M12 sensor connector for connecting any kind of Memosens sensor

• Optional: CDI connector for external access to the service interface (avoids having to unscrew the
housing cover)

External signals for device control and for activating external devices

Hardware options, e.g. module "DIO" with 2 digital inputs and 2 digital outputs or fieldbus module
"485" enable the following:

• via a digital input signal

• measuring range switching for conductivity (upgrade code required, see accessories)

• switching between different calibration datasets in the case of optical sensors

• an external hold

• a cleaning interval to be triggered

• switching on and off a PID controller, e.g. via the proximity switch of the CCA250

• the use of the input as an "analog input" for pulse-frequency modulation (PFM)

• via a digital output signal

• the static transmission (similar to a relay) of diagnostic states, point level switch states etc.

• the dynamic transmission (comparable to a non-wearing "analog output") of PFM signals, e.g. to

control dosing pumps.
