Mitsubishi Alarm Modems at a Glance State-Of-The-Art Communication

1 Mitsubishi Alarm Modems at a Glance

Mitsubishi Alarm Modems are new automatic modems with a large data memory, several func- tions and integrated Internet technology. They are designed as intelligent communication com- puters with a 32-bit power CPU and a 2 MB non-volatile Flash memory. This can now be expanded by up to 64 MB, thus providing enough space for your data requirements now and in the future.

Mitsubishi Alarm Modems are fully automatic and can

￿send alarm and status messages via SMS or Express E-Mail,

￿receive switch commands via SMS or Express E-Mail and forward them to a PLC,

￿send the data of a connected PLC/system,

￿transfer data between PLCs

What´s more:

￿You can use them as “normal” modems for the remote access of PLCs or systems, and the programming software of the PLC can generally be used for this.

1.1State-Of-The-Art Communication

The Mitsubishi Alarm Modem can communicate directly with the Mitsubishi PLCs using the relevant PLC protocol. Modbus RTU and Modbus ASCII are also supported. User-friendly XML-based soft- ware programs enable the required functions to be configured easily. The over twenty year history of modems being controlled by primitive AT commands can now be forgotten at last.

The wide range of functions available on the Mitsubishi Alarm Modems provide solutions for a number of applications such as the monitoring of temperature, pressures, levels, or the activa- tion of motors, fans, pumps slide valves and flaps.

1.2Easy To Retrofit

Mitsubishi Alarm Modems can be integrated in existing systems with a minimum of effort. The communication protocols of commonly used PLCs are already implemented and so modifica- tions to the PLC program are normally not required.
