3 Functional Description
3.1 Definitions
3.1.1 Objects, Instances, Object Short Names
Programming of the Moeller easy takes place via objects. A digital input, a regis-
ter, a counter for operating hours, a comparator, etc. are all examples for objects.
Each object has an object short name. The digital register, for example, has the
object short name "M", the analogue output has the short name "QA".
Several instances of each object are available to the programmer. The easy 500
device, for example, offers 16 digital registers “M”. The programmer can therefore
select the object instances "M1" to "M16".
3.1.2 Alias
As not only the programmer of the compact controller is responsible for mainte-
nance and operation of the Moeller easy device, it may not be clear for “outsiders”
which object instance has which function. Therefore, so-called aliases were intro-
duced for the INSYS GSM 4.2 easy. This offers the possibility to allocate a name
that is easy to understand. If the Moeller easy device controls a waste water sys-
tem, for example, the digital register M1 can be allocated the alias "waste water
pump1”. If an individual wants to activate the wastewater pump via mobile
phone, using an SMS, he does not need to know that the register 1 must be used,
but simply uses the term “wastewaterpump1”, Up to 30 object instances all in all
can be allocated aliases.
3.2 Automatic Actions
3.2.1 Object Instances Monitoring
The values of the easy object instances are monitored to enable a fault message
when values are changed.
Monitoring is performed during polling operation, i.e. the INSYS GSM 4.2 easy will
cyclically read out the easy object instances and can thus detect any changes. Up
to 10 object instances can be monitored altogether.
The query interval can be set to seconds (1 to 255 seconds). These times represent
minimum values. The actual monitoring interval may be slightly larger. If several
values that need to be monitored have been configured, the communication with
the compact controller may have a longer duration than the interval.
If a change of a monitored value is registered, the sending of a fault message is
prompted (SMS, SMS to fax, SMS to e-mail, SMS to fixed network).
For digital values, the following events (adjustable) can cause the sending of a
fault message:
