6 MODBUS-RTU PROTOCOL
By default, the instrument has MODBUS address
1
and communication parameters
19200, 8E1. The address and the communication parameters can be changed by using
the appropriate serial commands of the proprietary protocol or, alternatively, directly
with MODBUS commands by changing the value of the Coils and Holding Registers de-
scribed later.
The MODBUS-RTU protocol, if set as the operating protocol (default), is active after 10
seconds from the instrument power on.
In order to change the instrument configuration using the MODBUS-RTU protocol, the
value 1 must be written first in the
Coil number 2 (address 1).
Below is the list of registers (the tables show both the number and the address of the
registers, with the address of the register equal to the number of the register de-
creased by 1, as defined in the MODBUS standard).
