PQSTORI INSTRUCTION MANUAL
Modbus connection. The tables in this section
highlight key Modbus commands used to install
and run the PQstorI.

NOTE: All parameters with an address starting
in 3 are “Read Only”. Addresses starting in 4 point
to “Read & Write” parameters.
3.9.1 Measurements
Table 8 lists Modbus commands to check the
electrical network properties and system
settings described in Section 3.1.4.

3.9 Modbus commands
An external controller (e.g. an Energy
Management System) can be used to operate
the PQstorI remotely, provided that it can
communicate with the PQstorI over Modbus.
Section 4.8 provides guidance on cabling the
