Table J - 12: Reading of Multiple Data Registers With the Address Range 108-110
* N = Quantity of Registers
Note: With the Hydran 201Ti, the master can only write one logical value per request.
The number of registers accessed in that request depends on the type of logical value
the master is trying to change
Table J - 13 below presents, as an example, the writing of data registers with the
addresses 1 and 2.
