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
b send alarm and status messages via SMS or Express E-Mail,
b receive switch commands via SMS or Express E-Mail and forward them to a PLC,
b send the data of a connected PLC/system,
b transfer data between PLCs
What´s more:
b 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.
1.1
State-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.
1.2
Easy 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.
