Modbus/TCP Driver Configuration - Advanced Settings

Timestamp mode

Defines the timestamp mode (with or without milliseconds) for float transformations.

Register endianity

Defines which endianity should be used when reading/writing to a register.

Only active driver

This option defines that only the active driver connects to the PLC. You have to use this option in a redundant WinCC OA system in case of PLCs which can only connect to one Modbus client.

Swapped Bytes

The option defines if the Modbus driver shall swap the bytes of the 16bit Modbus registers (holding and input) for the corresponding connection.
