Further Information on the making of the two CRC bytes are available on the site www.modicon.com.

The F1X5 MODBUS commands are:

0x03: multiple reading of registers

0x10: writing of several registers.

0x03 READING OF REGISTERS

To read the registers of the instrument, the master must send a query composed as follows (every element is
a byte):

- START_REG_HI | START_REG_LO

is the address at the starting 16 bit for the reading

N_REG_HI | N_REG_LO

is the number (16 bit) of the registers to be read

The instrument replies with the following message:

DATA_1_HI | DATA_1_LO | DATA_2_HI | DATA_2_LO | …

is the sequence of the data

read..

NBYTE

is the number of the given bytes that follow

0x10 WRITING OF REGISTERS

To write the registers of the instrument, the master must send a query composed as follows (every element is
a byte):

NBYTE is the number of the given bytes that follow.

The instrument replies with the following message:

ATTENTION!!: to make operative the new value introduced you must send the “reload parameter”
command writing in the Operation Register (*) (address 0x15) the value 0x01.

Exceptions management:

In case the slave recognizes an error in the query received and addressed to it, it replies with an exceptional
message composed as following:

ADDRESS | FUNCTIO 0x80 | EXCEPT. CODE | CRC_HI | CRC_LO

The Exception Code can be one of the following:

Illegal Function

: The function code received in the query is not valid.

Illegal Data Address

: The address received in the query is not valid.

Illegal Data Value

: A value contained in the query is not valid.
