CORRIGO E VENTILATION VARIABLES FOR EXOLINE AND MODBUS 3.6 MANU

Chapter 2 System integration using Modbus 11
Reading values
An effective way to read values is to read multiple variables simultaneously. To, for example, read
all analogue outputs, set the Modbus query to the values shown in the figure below. The first analogue
output variable starts at address 54 (QAnaOut.AQ1). To read address 54 to 58, set the length to 5.
The Modbus answer will then communicate all 5 values in just one message, making the
communication more effective.
