USER MANUAL

Modbus TCP Interface (710-14812-00D)

9

7.

Operation

The Modbus TCP Interface must be controlled by a Modbus client (such as a PLC)
which complies with the Modbus Protocol Specification. For successful operation, the
client must also support all functions and interfaces described in this document.

7.1

Device Classification

The Modbus TCP Interface is a Modbus server and must be managed by a Modbus
client over Ethernet.

7.2

Ensuring Safe and Successful Control

Data written to the device will remain in its registers until the data is overwritten or
the device is reinitialised. The device will not transfer successive duplicate commands
to the soft starter.

•

If the soft starter is started via fieldbus communications but stopped via the keypad
or a remote input, an identical start command cannot be used to restart the starter.

•

If the soft starter may also be controlled via the keypad or the remote inputs (as
well as via fieldbus communications), a control command should be immediately
followed by a status query to confirm the command has been actioned.
