6.8 Simulation of analog / digital outputs
To check if subsequent circuits will work properly with output values provided by the device, using the
service menu
Simulation
all analog or digital / relay outputs may be simulated. This is done by either
entering analog output values or selecting discrete states for the digital outputs / relays.
When output simulation is turned on, the device configuration will be changed. This may take a few
seconds. Once the simulation is turned off, the device is switched off or the menu selection is changed,
the device goes back to its initial configuration.
Simulation is possible via webpage and as well via the local display.

6.9 Security system
The device provides several security mechanisms, which can be activated to ensure a comprehensive
access protection to all device data.
The
role-based access control
(
RBAC
) system allows restricting the access to measured data,
configuration settings and service functions to the rights granted to the present user. For access via
website or local display this is done by reducing the available menus and / or providing only read
access rights to specific services. For accessing data via external applications an API (Application
Programming Interface) key is required, which needs to be implemented as a special user.
For devices without Ethernet interface the RBAC is reduced to a simple password protection.
provides encrypted communication using TLS (Transport Layer Security)
Not available for devices without Ethernet.
Via
client whitelist
access to the device can be restricted to specific clients with definable IP
addresses.
Not available for devices without Ethernet.
Communication blocking:
Communication services, such as Modbus/RTU, Modbus/TCP or
SYSLOG are blocked by default and must be actively enabled via configuration. This way
unauthorized access may be prevented and possible intruding points eliminated.
: The device stores all security related messages in a separate list accessible via the
service menu. The content of this list can also be transferred to a central log-server using the
SYSLOG
protocol for security auditing.
Not available for devices without Ethernet. For devices without data logger messages get lost when restarting the
device.
If the device is equipped with a display, restrictions defined in the security system also take effect when
operating the device via the local display. It is also possible to restrict users to local access only.
