Description 1.
Introduction 1.1
IntesisBox
®
Modbus Server – Mitsubishi Heavy Industries AC is a communication gateway
for Mitsubishi Heavy Industries air conditioning (AC) systems to Modbus slave (RTU and
TCP).
This gateway allows integrating a Mitsubishi Heavy Industries AC system inside a
supervision/control/automation system through PLC, SCADA and, in general, through any
device or system with Modbus mastering (TCP or RTU) interface.
The aim of this integration is to make accessible several Mitsubishi Heavy Industries air
conditioning indoor units communicating with the Superlink protocol as if they were part of
a Modbus system. Therefore, the
IntesisBox
®
Modbus Server acts as a Modbus slave in the
Modbus interface, allowing the Modbus master read and write in the Modbus registers.
Moreover, IntesisBox
®
includes all hardware required to manage/control Mitsubishi Heavy
Industries indoor units without extra components needed.
