Fig. 114: Reading of response registers.
It is noticed that the block is the same "Modbus_Master". By changing the input values, you
configure it to be a write or read message, as well as you can configure the number of registers
or their location.
IMPORTANT: When configuring the "Modbus_Master" you must consult its documents so as not
to make mistakes in any of the block inputs. Depending on the MODBUS function used and its
content, it will be necessary to modify the inputs so that they adapt to the needs of each
information transmission.
