Other functions
In addition to sending and managing SMS messages, the SMS typical also processes two
globally valid functions. They are global because their execution is valid for all SMS jobs
connected with DB SMS_Data that is processed by the SMS typical. The two global
functions are:
● Status request for all SMS jobs of DB SMS_Data being processed by the typical.
The typical sends the status request to the TIM responsible for the SMS transmission.
This reports the current status of each SMS job in its memory back to the typical (status
messages 2, 3 or 8). The TIM closes the sequence of status messages with status
message 11 which indicates that no more status information is available.
This status request function executes only during the startup of the CPU and then only
when the SMS typical is enabled at this time (ENABLE = TRUE).
● Deletion of all SMS tasks of DB SMS_Data being processed by the typical.
Deletion takes place at several places:
– On the CPU: All jobs stored in DB SMS_Data.
– On the TIM: All jobs stored in the TIM for DB SMS_Data.
– In SMS-C: All jobs stored in SMS-C for DB SMS_Data (only when the SMS-C can be
reached over a fixed network).
● The delete function is executed automatically by the typical in the following situations:
– When the instance DB belonging to the typical is initialized.
– When DB SMS_Data to be processed by the typical is initialized.
– When a status change is detected at the ENABLE input of the typical.
The status request and the deletion function are time monitored. The duration of the
monitoring time is determined by the SupervisionTime (900 sec. by default) of the
corresponding subscriber object in DB BasicData.
If the supervision time expires before the status request or the deletion function can be
completed correctly, a message is entered in the diagnostic buffer of the CPU and a group
message "Supervision time has expired" is set at the Status output parameter of the SMS
typical.
As long as the status request or the delete function is active, processing of the SMS
messages is postponed and it is not possible to trigger a new SMS.
The current status of the status request or delete function is indicated at the Status output
word of the SMS typical.
