Slot and port assignment of the hardware modules• Inputs are assigned to measuring channels in theascending order of the slots and ports.
Adjacent example:"CH1: 1:1 pH glass" means:
Channel 1 (CH1) is slot 1 (basic module) : Port 1 (input1), pH glass sensor• Outputs and relays are named according to theirfunction, e.g. "current output", and are displayed inascending order with the slot and port numbers

4Order of the modules

Slot and port assignment on thedisplay

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 485DP or 485MB• Photometer module PEM• 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 modules 4AO or 2AO (AO = analog output)• Relay modules AOR, 4R or 2R (AOR = analog output + relay, R = relay)
With intrinsically safe sensor communication module 2DS Ex-i:• CM442/CM442R: always in slot 2• CM444/CM444R: always in slot 7 (two channel) and slot 6 (four channel)• CM448/CM448: slot 7, 6, 5
Modules with 4 ports are connected before modules of the same type with 2 ports.

Please note the following if upgrading the device:• Upgrade only to 1x 4 AO module possible• A maximum of two "DIO" modules may be used.

Basic rule for hardware
upgradesDetermining 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
2 inputs for photometer sensors = module PEM
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 typeand number of outputs.

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 entereddecides 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 485DP/485MB and current outputs
For PROFIBUS DP and Modbus RS485 communication protocols:
A maximum of 2 current outputs can be used in parallel.
Ethernet functionality via Base2 module and current outputs
A maximum of 6 current outputs can be used in parallel.
Bus termination on the device• Via slide switch at bus module 485DP/485MB• Displayed via LED "T" on bus module 485DP/485MB

Dependability
Reliability

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 theprocess• 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
MEMO

SENS

Heartbeat diagnostics• Heartbeat diagnostics screen with graphic indicators for the health of the device and sensor andwith a maintenance or (sensor-dependent) calibration timer• Heartbeat status information on the health of the device and condition of the sensor• : Sensor/device condition and 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.
An unhappy smiley can be due to the calibration result, the measured value status or to theoperating 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 fromto . The measured value is still reliable so the
NAMUR status signal does not change.
• If the maximum number of cleaning cycles is exceeded, the Heartbeat symbol changes fromto . 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 fromto and the NAMUR
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
For detailed information on "Ethernet/IP communication", see the product pages on the Internet(→ SD01293C).
For detailed information on "Modbus communication", see the product pages on the Internet (→SD01189C).
For detailed information on "PROFINET communication", see the product pages on the internet(→ SD02490C).
For detailed information on "PROFIBUS communication", see the product pages on the Internet(→ SD01188C).
More detailed information on HART communication is provided on the product pages on theInternet (→ SD01187C).
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 aminimum 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
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 alarmis 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

Ease of maintenance

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 anddigital communication• Upgrade to maximum 2 photometers and 4 Memosens inputs• 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 thehousing cover)A0034282
