14.3.5 Setting PROFIBUS Node Address via the Rotary Switches
The rotary node address switch of AHRTU-PFBS -5A is used for setting the node address of
AHRTU-PFBS-5A on the PROFIBUS DP network. The rotary node address switch consists of two
rotary switches, x16
0
and x16
1
. The range for either rotary switch is 0 ~ F.
The range for setting the node address is as the following table.
Address Definition
0
x16
1
x16
H’1 ~ H’7D Valid PROFIBUS address
H’0 or H’7E ~ H’FF Invalid PROFIBUS address
Example: If you need to set the node address of AHRTU-PFBS-5A to 26 (decimal), simply switch the
corresponding switch of x16
1
to “1” and the corresponding switch of x16
0
to “A”. 26 (decimal) = 1A
(hex) = 1x16
1
+ Ax16
0
.
Note:
 Switch off the power supply before setting up the node address of AHRTU-PFBS-5A.
Re-power the module after the setup is completed.
 Changing the value on the switch during the operation of AHRTU-PFBS-5A will not be valid
immediately until re-powering AHRTU-PFBS-5A after powering it off.
 Use the slotted screwdriver to set up the switch. Be careful not to scratch the module.
