Description
… / ...Modbus
4007 Device
Address
TUSIGN8 [1]
1 to 247
Setting of the Modbus device address.
Factory settings: see
Parameterization via the Modbus interface
on page 50.
4012
IEEE Number Format
TUSIGN8 [1]
0: IEEE-format activated
1: IEEE-format
disabled
Selection of the byte order for the Modbus communication.
• If the IEEE format is activated (1), the data words are sent in the ‘little-endian’
format, with the lowest value word transmitted first.
• If the IEEE format is deactivated (0), the data words are sent in the standard
Modbus ‘big-endian’
format.
Factory setting: IEEE format activated.

0: One stop bit
1: Two
stop
bits
Selection of the stop bits for the Modbus communication.
Factory setting: One stop bit
4011 Reponse
Delay
TUSIGN8 [1]
