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
0
rotary switches, x16 and x16
The range for setting the node address is as the following table.
Address
H'1 ~ H'7D
H'0 or H'7E ~ H'FF
Example: If you need to set the node address of AHRTU-PFBS-5A to 26 (decimal), simply switch the
corresponding switch of x16
1 0
(hex) = 1x16 + Ax16 .
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.
