The rotary node address switch consists of tworotary switches, x16 0 and x161. The range for either rotary switch is 0 ~ F.The range for setting the node address is as the following table.Address Definition0x161x1 6H’1 ~ H’7D Valid PROFIBUS addressH’0 or H’7E ~ H’FF Invalid PROFIBUS addressExample: If you need to set the node address of AHRTU-PFBS-5A to 26 (decimal), simply switch thecorresponding switch of x16 1 to “1” and the corresponding switch of x16 0 to “A”. 26 (decimal) = 1A(hex) = 1x16 1 + Ax160.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 validimmediately 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.
