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.
