5.11. The Event Manager Feature
The Event Manager feature means that the device can sense changes on its ports and is able to react
according to the pre-defined settings. Lightware Device Controller contains a user-friendly software tool and
allows creating Events by defining a Condition and an Action.

DIFFERENCE:
Below mentioned features are available from FW package v1.3.0.
The AND Operator
The practical experience has shown that there is a need to examine two conditions as follows: one condition
exists, and the other is a change that occurs. For example, in a meeting room we have the following situation:
Signal is present on an input port,
▪
▪ A GPIO pin state becomes 'low' (by an external device).
If the two Conditions are present at the same time, the Action is launched. Just create the two Conditions into
separate Events, then create a third Event, select the two Conditions and define the Action.
See the Create or Modify an Event
Event Manager Variables
A brand new area is opened by implementing the variables. You can create custom variables in number
or text format which can be used in the Event Manager. The variables can have the following properties/
methods:
Numeric (integer) type with min/max value setting, or string-type (determined automatically)
▪
▪ Increment/step the numeric value,
▪ Value-dependent case operations,
Reading and storing the value of an LW3 property into a string or a numeric variable.
▪
The defined variables are stored in a non-volatile memory and the value is kept in case of a reboot. The
new opportunities allow creating a monitoring/controlling system without connecting an additional control
processor.

Condition Trigger
This improvement in the Event Manager works as if a condition is detected. When a complex control system
is built, a Condition may trigger numerous Actions. A typical example is when a system is powered on and
the 'ready-to-use' state has to be loaded. In this case, there could be many actions which are based on the
same condition. In order to reduce the number of the commands, you can trigger one 'key' condition, which
could start the whole process.
See the
5.12. Basic IT Security
These entry-level network security improvements help to prevent unauthorized access to the Lightware
device:
▪ Cleartext login
▪ IP Port Block
▪
MAC Filtering
The Cleartext Login tool allows setting a password for login, thus, the device will not accept any command
coming from an interface (RS-232, Ethernet, etc...), only the device type and the serial number can be queried
without login. You can set all affected TCP/IP ports individually to enable or disable.
The IP Port Block feature is an additional protection for the Cleartext login. There are TCP/IP ports in
Lightware devices which are not protected by the login, so you can disable them if necessary. Example: due
to the working method of the LW2 communication, the Cleartext login does not provide protection when LW2
command is sent to the device, that is why the TCP port no.10001 shall be blocked manually.
Another level of security is the MAC Filtering tool. You can create an 'allowlist' of network devices based on
the MAC address which are allowed:
Controlling the device (Send option), or
▪
▪ Querying parameters (Receive option) to/from the Lightware device.
