Warning and control SMS
Automatic sending of a preset warning or control SMS can be triggered not only by ex-
ceeding the preset limit value on the measuring channel, but also by a change in the
state of the binary channel, an error in the measuring signal, activation or deactivation
of an alarm on the channel, etc.
The H40G continuously evaluates the current measured values on both analogue and
binary channels. If the value exceeds the set limit or if a binary input is switched on or
off, it sends a pre-prepared SMS to selected mobile phones.
For integral variables (instantaneous or cumulative flow, rainfall, number of pulses, ...),
the activation of the SMS warning can also be triggered by exceeding a pre-set limit
value for a certain time.
Warning messages are the basic and most frequently used type of SMS in the communi-
cator. The features of warning SMS can be summarized in the following points:
▪
The user can set the text of up to fourteen different warning messages.
▪
At the beginning of each alert SMS it is possible to automatically insert the name of
the device sending the message and the current time in the device at the time of
sending the SMS. Only then is the actual text of the message followed.
Note: in special cases, such as sending a message to a special operator number
that forwards incoming messages to e-mail, it is necessary to disable the automatic
insertion of the name tag and time.
▪
For each message, you can select the recipient from a list of authorised persons.
You can also create a group of persons to whom the SMS will be sent in turn.
▪
The sending of the message can be conditioned by the time period for which the
activation condition of the message must be fulfilled (overshoot, undershoot, binary
state change, measurement error, alarm).
▪
Resending of the next warning message is activated only after the current value
returns to the allowed area by at least the
Hysteresis
value and after the
Limit value
is exceeded again for the set Delay time.
▪
It is possible to insert the current measured value into the text of the warning SMS
using the #V character pair. Not only the current measured value, but also the chan-
nel name and the set units of measurement are transferred to the SMS text.
▪
The text length of one SMS must not exceed 50 characters (this limit does not in-
clude automatically inserted texts -
name tag
, time, current value).
