4.11.5.3 Setting a PROFIBUS Node Address by the Knobs 
The address knobs on AH10PFBM-5A/AH10PFBS-5A are used to set the node address of AH10PFBM-
5A/AH10PFBS-5A on a PROFIBUS-DP network. They are knobs which can be turned. One knob corresponds 
to x16
0
, and the other node corresponds to x16
1
. Setting range: 0~F   
Address  Definition 
H’1~H’7D  Valid PROFIBUS node address 
H’0 or H’7E~H’FF  Invalid PROFIBUS node address 
 
Example: If the node address of AH10PFBM-5A/AH10PFBS-5A is 26 (decimal value), users have to turn the 
knob corresponding to x16
1
 to position 1, and turn the knob corresponding to x16
0
 to position A.   
26 (decimal value)=1A (hexadecimal value)=1×16
1
+A×16
0
 
Points for attention:
 
  If users set the node address of AH10PFBM-5A/AH10PFBS-5A when AH10PFBM-5A/AH10PFBS-5A is 
not supplied with power, they have to power AH10PFBM-5A/AH10PFBS-5A after the node address of 
AH10PFBM-5A/AH10PFBS-5A is set. 
  If users change the node address of AH10PFBM-5A/AH10PFBS-5A when AH10PFBM-5A/AH10PFBS-5A 
is powered, the change will not take effect immediately after the node address of AH10PFBM-
5A/AH10PFBS-5A is changed, and it will take effect after the users cut off the power supplied to 
AH10PFBM-5A/AH10PFBS-5A and then power AH10PFBM-5A/AH10PFBS-5A again. 
  To prevent the address knobs on AH10PFBM-5A/AH10PFBS-5A from being scratched, please carefully 
use a slotted screwdriver to rotate the address knobs on AH10PFBM-5A/AH10PFBS-5A.
