3. Setting a PROFIBUS node address by means of the address knobs
The address knobs of AHRTU-PFBS-5A are used for setting the node address of AHRTU-PFBS-5A
on a PROFIBUS-DP network. There are two address knobs. They are a knob corresponding to x16
and a knob corresponding to x16
The range for setting the node address is described below.
Address
H'1~H'7D
H'0 or H'7E~H'FF
Example: If users need to set the node address of AHRTU-PFBS-5A to 26 (decimal value), they have
to turn the knob corresponding to x16
26 (decimal value)=1A (hexadecimal value)=1x16
Points for attention:

If users set the node address of AHRTU-PFBS-5A when AHRTU-PFBS-5A is not supplied with
power, they have to power AHRTU-PFBS-5A after the node address of AHRTU-PFBS-5A is set.

If users change the node address of AHRTU-PFBS-5A when AHRTU-PFBS-5A is powered, the
change will not take effect immediately after the node address of AHRTU-PFBS-5A is changed,
and it will take effect after the users cut off the power supplied to AHRTU-PFBS-5A and then
power AHRTU-PFBS-5A again.

To prevent the address knobs on AHRTU-PFBS-5A from being scratched, please carefully use a
slotted screwdriver to rotate the address knobs on AHRTU-PFBS-5A.
