Setting up SREA-01 for typical applications
44
2. Configuring the Modbus/TCP client application that connects to SREA-01
Typically, you have to configure these settings in your Modbus/TCP application:
• IP Address: The IP address of SREA-01
• IP Port: The port defined on the Modbus setup page, for example 502
• Unit ID/Node Addresses: The node address of the drive in question. If you want to
access the internal registers of SREA-01, use the Internal module registers via
Modbus/TCP Address that is defined on the page Setup – Modbus.
• IO Type: holding register (Address area starting from 40000)
• IO Addresses:
• If the drive is configured to be controlled from the Modbus interface, the control
words, references, status words, etc. can be accessed in registers 40001, 40002
and so on. Usually the register 40001 is the control word, 40002 is the first
reference and 40004 is the status word, for instance. For more information, see
the manuals of your drive and the Modbus adapter.
• For parameters and actual values, multiply the group by 100 and add the
parameter number. For example, to access the parameter 12.02, use the address
41202.
Note:
The control and status words can not be accessed if you are connected to the
panel port or if you have not configured the drive to be controllable by the Modbus
adapter. See the drive manual for more information.
Note:
Some Modbus applications do not need the leading “4” in the holding register
addresses. In such cases, the parameter 12.02 is 1202 instead of 41202. See the
manual of your Modbus application for more information.
