Logic status of the outputs of the slaves on the bus
These words contain the logic status of the digital outputs of all the slaves
on the bus: based on the set slave address the instrument determines its
reference word (e.g. Slave 1-word 1201 .. Slave 10-word 1210...) and sets
the outputs based on the value of the word.
It is used to set all the outputs by writing in broadcast on the slaves on the
bus

Access to the Slave Address Automatic Assignment function.
To use the Slave Address Automatic Assignment function you need to
connect the Q-ID clip to the I-ID clip of the next module: the first will have
I-ID free, while in the last one the clip Q-ID will be free.
For the entry (exit) of all the modules connected to the bus, in the Slave
Address Automatic Assignment function you need to write 1 (0) on this
word in broadcast. Once the address is assigned (see following word), exit
from the procedure by writing 0 on this word, obviously with the slave
address just assigned.

Slave address assignment
In order to assign the address write the password 1234 on this word: the
address used to write will be one that the slave will assign to itself. The
new address will be assigned only with the module with the I-ID input
disabled and currently still with the assignment procedure active, and will
respond to the writing command.
