SMS SERVICE
3. SMS SERVICE
The SMS service provides user with a limited remote access to the drive by means of SMS messages
(Short Messages Service) where GSM/GPRS networks are available.
Thanks to this service, the user can remotely:
Check the status or value of some visualization parameters (included in ‘V Visualization’ menu).
This information is obtained as a result of a request by the user (response from the drive), and
additionally, with a configurable periodicity if it is required.
Start, stop and reset the drive.
Be notified about any start, stop and fault event that have been produced.
The service interfacing is quite easy. There are two types of interactions:
The user sends a SMS with a specific command to the graphic display. The graphic display
processes the message and sends user a response. First, the display will check the user rights or
permissions, and if the user is authorized, then the display will process the SMS and send user the
requested response.
The command can be configured in the graphic display just to read the value for some parameters
of the drive and send the values back to the user. This type of commands is called ‘query
messages’.
Also, the command can be a start, stop and reset order for the drive. This type of commands is
called ‘special messages’.
All attributes for the commands (labels, associated parameters, parameter alias, etc.) are
customizable by the user.
The graphic display sends user (or user group) a SMS at specific moments. The service can be
configured in order to advise the user when motor starts or stops and when a fault is generated in
the drive. These messages are called ‘notification messages’.
There is other type of messages maybe it could be included in this group. These ones are
messages sent by the display graphic to the user at specific moments, based on a periodicity
predefined by the own user, where the values of some drive parameters are shown. These
messages are not ‘notification messages’, they are a query message subtype.
The graphic display adds a header on all messages sent to the user. In this way, it is easy for the user to
identify the sender.
The service includes a user management system. When a specific user wants to use this service, he
should be registered and the proper rights or permissions should be assigned to him.
The system is highly configurable. The user can set:
The header to identify the drive.
User phone numbers and rights for each user.
Labels for all messages.
User defined messages.
