For the values to be monitored applies that all changes must be effective until the
automatic polling is performed again. This applies to most applications (e.g. fill
level monitoring or protective motor switch).
Monitoring with INSYS GSM 4.2 easy is mainly intended for static signals and val-
ues.
If the used signal (e.g. pulse) does not comply with these requirements, this signal
must be directed to an ON or OFF delay or a RS flip-flop in the control program.
Occurrence of several faults/changes
If several changes occur during a polling interval, the according messages are sent
in the same order in which they were set during the configuration of the INSYS
GSM 4.2 easy. The monitored value 1 is therefore queried prior to the monitored
value 2. If exceeding or changing of values is detected, the system will immedi-
ately attempt to send the alarm message.
If another monitored value changes during the alarm processing, this new alarm
is only detected if the value change lasts until the processing of the previous
alarm is completed. Now the regular polling will restart.
3.2.2 Periodic SMS
In addition to the monitoring of values, it is also possible to periodically query the
current condition or value of an object instance and to send it automatically via
SMS.
A periodic SMS can be sent in hourly intervals of 1 to 255 h. After this time has ex-
pired, the set object instance is read out and the value is sent as SMS.
The query of the object instance is performed up to three times, if necessary. If
there is still no reply from the easy device, an SMS with the text „
NO SUCCESS
” is
sent instead of the object instance value.
The sending of this SMS will be delayed, if one of the following functions is per-
formed at this moment:
Login state/field strength query (the LEDs STATUS and SIGNAL are up-
dated); duration approximately 50 seconds, interval 60 seconds (may be
switched off, but then the LEDs are no longer operated)
Query of the SMS input buffer and processing of incoming SMS commands,
if required; duration approximately 5 seconds plus processing time for
command; interval 60 seconds (may be switched off, but then que-
ries/configuration via SMS are no longer possible)
GSM connections active (data connection, DTMF connection, security call-
back)
Sending an SMS (fault message, Alive SMS may be switched off, Power up
SMS may be switched off); duration approximately 10 seconds.
If the LOGOUT time is active when the periodic SMS are processed, the module is
logged in at the GSM network before sending, and logged out afterwards.
Periodic SMS are only sent to one destination. The usage of further recipients is
not possible.
