4.3 Rules
•
As in the previous case, it is necessary to input the name of the
Rule
, whether it is active or not and in
what schedules it should operate.
•
The
Rule Text
part then serves for the complete text of the rule, using the identification names
of each device (see chapter 3.2), proper event names or variables.
For example, if you want the
rule to create a variable and then display it in a variable monitor, you need to input the string
setpublic(name of the variable,1) into the text of the rule. It will then be possible to add the variable
as the pair of “device that triggers given rule – the name of the variable.”
Before editing any rule in the text form, please take into consideration that when a rule is changed in the text
mode, you cannot get back to editing it in the form template mode.
In all cases, confirm the changes by clicking the
Apply Changes
button.
To edit the existing rules, go into the menu
Management – Rules – Manage
. This menu appears only if there
already was at least one rule created.
To change the settings of an existing rule (for example, change the text of the automatic e-mail, or the
temperature level that should trigger the event), click the
Edit
button located in the appropriate line. The same
form as when creating a rule appears (i.e. for the rules created using the template mode, the template form will
appear, for the ones created using the text mode, the text mode form will appear).
Confirm the changes by clicking the
Apply Changes
button.
The Remove button located next to the
Edit
button (i.e. in the appropriate line of the form in the menu
Management – Rules – Manage
), serves for deleting the particular rule.
There is no need to delete a rule if you only need to temporarily deactivate it. It is enough to make sure that
the Enabled checkbox in the rules settings is not ticked, or perhaps just select a different schedule that fits the
desired operational pattern better.
4.3.1
Rule Examples
Trigger Camera Turn to preset position
To be able to create the rule that will turn the camera to some
position, it is necessary to create the predefined position first. This can be done in the web form of the camera
(
Management – Devices – Manage – Address
or you can directly enter in the IP address of the camera into
your internet browser). The way you define the position differs according to the camera type and should be
described in its manual.
Assuming that we already have a predefined position named Position1 and created button that calls a user
event named UserEvent1(for more about setting the user buttons and events see part Views), we can create
the rule that after pushing the button turns the camera to the Position1 (Figure 30).
Hint: By creating multiple rules, you can move the camera by clicking the buttons to different positions.
Recording as a reaction to the change of digital input
( status change, button pressed, alarm etc.) on
camera or on a Poseidon device.
