Replacing PROFINET Scanner Hardware
If a PNS module needs to be replaced for any reason, the steps to commission a new hardware
module are below.
If the replacement PNS module has no assigned name (the CONNECT LED is blinking Amber
slowly), the network cabling can be plugged back in and the name assigned over the IO
network. If there is a possibility of duplicate names existing on the network due to a pre-existing
IO-Device name assigned in the replacement module, the IO-Device Name should be assigned
before inserting it into a working IO network. The IO-Device Name and IP Address settings can
be updated offline (for example, in an office setting).
1. Remove power from the previous PNS module. This should be done before network
cabling is removed, especially in the case of fiber connections.
2. Remove network cabling from the old module.
3. Remove the old module.
4. Insert the new PNS module.
5. Connect network cabling to the new PNS module.
6. Apply power to the new PNS module hardware.
7. Optional: Assign IP address settings to the new PNS module using the DCP tool if this
was not done offline. The IO-Controller will update any IP address settings automatically
when it connects if this step is skipped.
8. Assign an IO-Device Name (page 3-10) to the new PNS module hardware if this was not
done offline.
