1)Example: you want to loop the signal from the alarm relay to a siren and a lamp. The terminals on the
alarm relay only accommodate one cable. Route the signal from the alarm relay to a terminal on the
distributor block. The block's terminals are all interconnected. You therefore have 3 additional terminals on
this block from where you can carry the signal forward to the consumer (siren, lamp etc.). The signal can
be multiplied in this way.

7.1.2 Establishing the data connection
All versions with the exception of PROFINET:
To ensure that your device has a valid IP address, you must disable the DHCP parameter in
the Ethernet settings. (Menu/Setup/General settings/Extended setup/Ethernet/
Settings)
You can assign the IP address manually in the same menu (for point-to-point
connections).
All versions including PROFINET:
The device's IP address and subnet mask can be found at: DIAG/System information/
Ethernet.
1.Start your PC.
2.First, configure a manual IP address in the network connection settings of the
operating system.
Example: Microsoft Windows 10
3.Open Network and Sharing Center.
Apart from your standard network, you should see an additional Ethernet
connection (e.g. as "Unidentified network" ).
4.Select the link to this Ethernet connection.
5.In the pop-up window select the "Properties" button.
6.Double-click "Internet Protocol Version 4 (TCP/IPv4)".
7.Select "Use the following IP Address".
8.Enter the desired IP address. This address must be in the same subnet as the IP
address of the device, e.g.:
IP address for Liquiline: 192.168.1.212 (as configured previously)
IP address for PC: 192.168.1.213.
50Endress+Hauser
9.Start the internet browser.
Page 51
Liquiline CM44PSystem integration
10. If you use a proxy server to connect to the internet:
Disable the proxy (browser settings under "Connections/LAN settings").
11. Enter the IP address of your device in the address bar (192.168.1.212 in the
example).
The system takes a few moments to establish the connection and then the CM44
web server starts. You might be asked for a password. The factory setting is
"admin" for the user name and "admin" for the password.
12. Enter the following address(es) to download logbooks:
192.168.1.212/logbooks_csv.fhtml (for logbooks in CSV format)
192.168.1.212/logbooks_fdm.fhtml (for logbooks in FDM format)
Downloads in FDM format can be securely transmitted, saved and visualized with
Endress+Hauser's "Field Data Manager Software".

→ 64
•: 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.
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 to . 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
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 to and the
NAMUR status signal also changes immediately to F (failure).

The change in the process - for example, concentration measurement with a varying
medium composition (milk, cream, yogurt) - can be communicated to the transmitter by a
binary input signal. Binary inputs and fieldbus signals are available. For this, your device
must have the appropriate hardware and the necessary activation codes.
You can specify a maximum of 3 dataset switches. Each switch has two states (binary
encoding). Therefore you have a maximum of 23=8 signal combinations for dataset
switching.

Outputting the controller manipulated variable via the current output
Unipolar+ Assign to the output to which an actuator that can increase the measured value
is connected. Unipolar- Assign to the output to which an actuator that can decrease the
measured value is connected.
To output the manipulated variable of a two-sided controller, positive manipulated
variables and negative manipulated variables generally have to be output to different
actuators, as most actuators are able to influence the process in one direction only (not in
both). For this purpose, the instrument splits the bipolar manipulated variable y into two
unipolar manipulated variables, y+ and y‐.
Only the two unipolar manipulated variable parts are available for selection for outputting
to modulated relays. If outputting the values via a current output, you also have the
possibility of outputting the bipolar manipulated variable y to one current output only
(split range).
10.4.2 Alarm relay and optional relays
The basic version of the device always has one alarm relay. Additional relays are also
available depending on the version of the device.
The following functions can be output via a relay:
• Limit switch status
• Controller manipulated variable for controlling an actuator
• Diagnostic messages
• Status of a cleaning function in order to control a pump or a valve
You can assign a relay to multiple inputs in order to clean several sensors with just
one cleaning unit, for example.

Outputting diagnostic messages via the relay
If a relay is defined as a diagnostic relay (Function = Diagnostics), it works in the "failsafe mode".
This means that the relay is always energized ("normally closed", n.c.) in the basic state if
an error is not present. In this way it can also indicate a drop in voltage, for example.
The alarm relay always works in the failsafe mode.
You can output two categories of diagnostic messages via the relay:
• Diagnostic messages from one of the 4 Namur classes → 137
• Diagnostic messages which you have individually assigned to the relay output
A message is individually assigned to the relay output at 2 specific points in the menu:
Before being able to assign the relay output to a special message in Diag. behavior
you must first configure Outputs/Relay x:y or /Alarm relay/Function = Diagnostics .

• Via a digital input signal
• measuring range switching for conductivity (upgrade code required, → 182)
• switching between different calibration datasets in the case of optical sensors
• external hold
• a cleaning interval to be triggered
• PID controller switch-on/switch-off, e.g. via the proximity switch of the CCA250
• the use of the input as an "analog input" for pulse-frequency modulation (PFM)
• the setting of the optical zero point or a manual offset for photometer sensors
• Via a digital output signal
• diagnostic states, point level switches, or similar states transmitted statically (similar
to a relay)
• the dynamic transmission (comparable to a non-wearing "analog output") of PFM
signals, e.g. to control dosing pumps

Utilize the advantage of the effectively wear-free control with binary outputs versus a
control system with relay. With pulse frequency modulation (PFM), it is possible to achieve
virtually continuous dosing using a dosing pump with higher input frequency.
1.Connect the INS proximity switch of the CCA250 assembly to a digital input of the
DIO module (e.g. slot 6, port 1).
2.In the software, configure a controller and as the source select the binary input
(e.g.Binary input 1) to which the proximity switch is connected. (Menu/Additionalfunctions/Controllers/Controller 1/Controller Enable = Binary input 1)
3.Signal type: For the selected input, select the factory setting (Static signal).
4.Connect the measured value of a flowmeter to the second input of the DIO module
(e.g. slot 6, port 2).
5.Signal type: for this input, select PFM . (Menu/Inputs/Binary input6:2/Signaltype = PFM)
6.Input variable: select the corresponding measured value (Flow rate).
You can now use the input you have just configured as the disturbance variable
for your controller

7.Disturbance variable: in the controller menu, select the binary input to which you
have connected the flow measured value. (Menu/Additional functions/Controllers/
Controller 1/Disturbance variable/Source of data = Binary input 6:2 and
Measured value = PFM value)
8.You can activate a dosing pump through PFM via a digital output of the DIO module.
Connect the pump to an output of the DIO module (e.g. slot 6, port 1) and select the
following settings in the menu: Menu/Outputs/Binary output6:1/Signal type =
PFM and Source of data = Controller 1.
Take the direction of action of your dosing into account. Select the correct parameter
(Actuator type = Unipolar+ or Unipolar-).
You must make additional settings in the controller menu to fully customize the control to
suit your process conditions.
