Assigning Io-Device Names; Clearing The Io-Controller Configuration; Replacing Pac8000 Profinet Scanner Hardware - GE PAC8000 series User Manual

Assigning IO-Device Names

3.3
After the PNS and other IO-Devices on the LAN have been entered into the configuration, a
Discovery and Configuration Protocol (DCP) tool must be used to assign a name to each IO-
Device. The Name of each device on the LAN must match the configuration. This step is
required before downloading the configuration from the PROFINET IO-Controller, otherwise
the PROFINET IO-Controller will be unable to connect to the devices and deliver their
configuration.
The DCP tool must be connected to PROFINET IO LAN, either through the PROFINET
IO-Controller or directly to the LAN depending on whether it operates through the
IO-Controller or directly to IO-Devices.

Clearing the IO-Controller Configuration

3.4
The PAC8000 PROFINET Scanner reacts to clearing the PROFINET IO-Controller as a loss
of connectivity, and takes appropriate actions such as setting outputs to the failsafe state.
Clearing the IO-Controller does not typically cause a clearing action on all connected
IO-Devices.

Replacing PAC8000 PROFINET Scanner Hardware

3.5
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 blinks 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).

Power down the PNS.
Remove network cabling from the module.
Remove the old module.
Insert the new PNS module.
Connect network cabling to the new PNS module.
Apply power to the new PNS module hardware.
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.
If an IO-Device Name was not assigned to the new PNS module, assign it now.
