1. Setting a PROFIBUS node address
The address knobs of AH10PFBS-5A are used for setting the node address of AH10PFBS-5A on a
PROFIBUS-DP network. There are two address knobs. They are a knob corresponding to x16
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 AH10PFBS-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 AH10PFBS-5A when AH10PFBS-5A is not supplied with power,
they have to power AH10PFBS-5A after the node address of AH10PFBS-5A is set.

If users change the node address of AH10PFBS-5A when AH10PFBS-5A is powered, the
change will not take effect immediately after the node address of AH10PFBS-5A is changed, and
it will take effect after the users cut off the power supplied to AH10PFBS-5A and then power
AH10PFBS-5A again.

To prevent the address knobs on AH10PFBS-5A from being scratched, please carefully use a
slotted screwdriver to rotate the address knobs on AH10PFBS-5A.
