Validity of the supplementary instruc‐
tions
IP address
These supplementary instructions are only valid when used in con‐
junction with the operating instructions for the Multi-parameter con‐
troller diaLog DACb.
The IP address is an address in computer networks, which, like the
internet, is based on the internet protocol (IP). The IP address is
assigned manually or automatically (DHCP) to devices when
devices are integrated within a network. An IP address makes
devices accessible within a network. The IP address of the diaLog
DACb controller is the network address at which the web interface
of the controller can be accessed in the network.
You can configure the IP address of the controller in the menu of
the controller. You can choose between manual input and auto‐
matic assignment by a DHCP server. Inputting the IP address and
the subnet mask is essential with manual input. Details of the
gateway and DNS server are optional and dependent on the net‐
work to which the controller is connected. If in doubt, request the
necessary information from the responsible person within your
organisation.
A common private IP configuration might be:
n IP: 192.168.000.001
n Subnet mask: 255.255.255.000
There needs to be a DHCP server within the connected network to
enable you to use automatic assignment of the network configura‐
tion. When the controller starts up, it requests a valid configuration
from the DHCP server and takes over this configuration.
You can then view the IP address assigned by DHCP in the
‘Setup’
connected directly to a PC/laptop, check that the PC/laptop does
not have DHCP server functionality. Should this be the case, then
the IP address must be assigned manually. The PC/laptop then
has to be set up for manual assignment of IP addresses. The IP
addresses have to lie within the same address range, for example
PC/laptop: 192.168.000.010, diaLog DACb 192.168.000.001, both
with the subnet mask: 255.255.255.000. A cross-over LAN cable
may need to be routed between the diaLog DACb and the PC/
laptop depending on the age of the PC/laptop.

Main display
The main display of the web interface provides a complete over‐
view of the current status of the controller. 1, 2 or 3 main channels,
and where applicable the mathematical supplementary channel,
are displayed depending on the design and configuration of the
controller.
2.1 Main Display of a Channel
Fig. 1: Main display
Fig. 2: Main display of a channel
The main displays of a measuring channel provide information on:
n Measured variable
n Measured value
n Current setpoint
n Measuring range limits
n Set alarm limits
n Control variable
n Temperature compensation
n Active parameter set
n Correction variables
n Interference variable (e.g. flow)
Use the
[Settings]
button to change the configuration of a meas‐
uring channel if you have the requisite access code for the con‐
troller.

2.2 Access Code
2.3 "Start/Stop" Key
Authorisation is needed to operate the controller. Four-digit access
codes must be issued in the
troller for the various users and the access code of the controller
has to be activated for this.
The password entered is transmitted encrypted to the controller.
If no user has been authorised, the web interface merely provides
information about the current status. Only authorised users can
stop the controller or acknowledge errors.
A login with at least
parameters.
Use the Start/Stop key on the web interface to start or stop the
controller. This function corresponds to the local Stop key.
The following applies:
n You cannot restart a controller via the web interface, which has
been stopped by the local key.
n You cannot restart a controller using the local key, which has
been stopped via the web interface.

You can also use the local Start/Stop key to start the controller if it

The Start/Stop key is only active if a user with a sufficiently high
access level is logged on.

The global error list shows all existing warnings and errors from all
activated channels. You can confirm the errors by clicking on
‘OK’
if you are logged on as an authorised user.
The error list of a channel is automatically expanded when the
error display is opened if there is at least one unconfirmed error.
The error list of this channel is hidden if all errors of a channel have
been confirmed or are merely warnings, and you can open the
error list by clicking on the
‘+’
key. The error numbers of the error
list correspond to the errors in the controller's local display
