4.1.2 Addressing

The network adapter on the PROFIBUS-DP is addressed via the two rotary switches.
Note: A maximum of 125 addresses (1 to 125) can be assigned. Each address may be assigned only
once in the overall bus structure. Addresses 1 and 2 are generally used by the control
systems. Bus addresses 000 plus 126 and higher may not be used.
The most significant digit is set with rotary switch H, the least significant digit with rotary switch L .
The switches are labelled in the hexadecimal numbering system (0 to 9, A=10, B=11, C=12, ... F = 15). A
hexadecimal to decimal conversion table is provided in the annex.
Coding: Address = (H*16) + L
Addressing examples:
PROFIBUS address 15: H = 0, L = F
PROFIBUS address 112: H = 7, L = 0
PROFIBUS address 44: H = 2, L = C
