SMS and Paging Utility From version 2.02 onwards of MiriMap 2000+, the MiriAD 2000 units have an in-built capability to send SMS (Short Message Service) messages via suitably connected GSM mobile phones or via dial-up PSTM modems to pager and SMS services providers that support the TAP Protocol (Tele-Alphanumeric Protocol). It is also possible to interrogate the MiriAD 2000 physical memory directly from another GSM mobile phone if the MiriAD 2000 unit has a suitable GSM phone connected and configured on one of the available RS232 ports. The MiriAD 2000 units can be programmed to send SMS messages via the normal parcel mechanism that is used to generate data transmissions using the event mechanism in conjunction with the Ladder Diagram functions. This provides a high degree of flexibility to allow the user to configure simple alarm monitoring schemes. These could be based on, for example, level and flow monitoring (using any of the analog I/O channels on the MiriAD 2000 unit) or status monitoring on contact closures on any of the digital inputs or outputs. More complex schemes are possible with the in-built timers and counters inherent to the MiriAD 2000 units. Direct SMS Interrogation of MiriAD 2000 unit It is also possible to use a handheld GSM phone that is capable of transmitting and receiving SMS messages to retrieve physical memory variables, without interfacing to the configured map. The MiriAD 2000 unit must have a GSM modem attached and the user must know the phone number assigned to that modem and if there is a PIN number assigned to the unit that must also be know. Knowledge of the format of the memory variables is also required to understand the responses if long and real numbers have been used (the memory type by default is normally 16 bit unsigned integer). This offers some protection and security by limiting access to personnel who have been given access to the phone number and PIN and map configuration of variables.
