This script is used to notify the RICH experts in case of an alarm in PLC_1, which is controlling the RICH gas system. It checks periodically the value of the following dp: 'PLC1_AI_Alarm.value'. If the value of the dp is not equal to 0 the perl script called "sms.pl" is being called. Also in the case of an alarm the text file is created under /tmp folder which contains the value of an alarm.
This script has a connection to PVSS database and periodically checks the value of the alarm. In case of an alarm it calls the Perl script called `sms.pl' where the real connection to CERN sms service has been made.
