Modbus SMS Alert (SMSTA)

Astute Messaging


SMS Alert Module sends out alerts to industrial automation, building automation, fire safety, and similar applications, where the timely alert to multiple people is important. SMS alert module has a standard Modbus TCP/IP interface which makes it compatible with most of SCADAs and PLCs etc. Based on the alarm, it sends pre-configured SMS text to pre-configured mobile numbers. In this way even when the user is far off he can get to know the system’s alarm and take preventive measures by connecting to the control room. By this user can have control of the system even from a remote location.
