3.3.1 Correspondence between Drive Parameter ID and Communication Protocol
Address
The following table provides drive parameter IDs and the corresponding Modbus™ addresses.
The following data is provided:
● Parameter ID
The drive parameter ID number to enter via the keypad or the ToolSuite.
● Modbus™ Address
A digital location provided by the Modbus™ Protocol, which stores values for use by the
master (PLC) and slave (Siemens drive) devices. To establish functional communication
between the PLC and the drive via the drive's Modbus™ connection, the control software
in the drive must be configured to know what certain addresses are used for.
● Data From Drive
Data that the PLC will receive from the drive to determine how the drive is functioning.
Each register contains a 16-bit digital representation of the status of a particular aspect of
drive functionality.
Some registers are fixed to track certain drive functions; others are programmable to track
any of a number of drive status choices.
● Data To Drive
Data that the PLC will send to the drive to control it.
Each register contains a 16-bit digital representation of the PLC's command for a particular
aspect of drive functionality.
Some registers are fixed to control certain functions; others are programmable to control
any of a number of drive function choices.
