3.4 Modbus RTU

3.4.1 Addressing
3.4.1.1 Hexadecimal coded address switches
The address of the Modbus interface can be adjusted by the two 16-stage DIP switches
(hexadecimal coded) on the front of the controller. The address ranges from 1(0x01) to
247(0xF7). If the address is set outside of the valid range, the standard address 47(0x2F) will
be used. The new settings will take effect after a power-down-reset (restart of the device).

Caution
Take care not to give any controller address double. System instability or
access fail within the RS485 network can result because of address conflict.
3.4.1.2 Decimal Address Switches
The address of the Modbus interface can be adjusted alternatively for newer devices by the
two 10-stage DIP switches (decimal coded) on the front of the controller. The address ranges
from 1 to 100. When the switches adjusted "0" "0", the address is "100". The new settings
will take effect after a power-down-reset (restart of the device).
