1. Introduction
SMS-531 is an intelligent 3G Modbus/SMS gateway for industry M2M
applications. It is convenient for users to apply to M2M applications with the host like
PC, PLC, HMI and PAC via Modbus RTU communication. It supports UNICODE
format for users to send SMS messages to the specific mobile phones by Modbus RTU
protocol with various language. That can make the current system to M2M applications.
Moreover, the SMS-531 also supports the sound alarm application with the pre-defined
voice files. It can be used to inform operator the urgent event immediately. For
managing more SMS-5xx series remotely, ICP DAS provides SMS DBS software for
users to apply in the system.
