Configuration Faults

6.1
If there are differences between the expected, configured modules and the I/O modules physically
present in the PNS rack, and/or differences between the expected and detected slot locations, the
PROFINET Scanner indicates those differences back to the PROFINET Controller once a connection is
established.
• If an I/O module is configured, but is not present or operational in the rack, the PNS indicates the
difference to the PROFINET Controller, and the Controller generates an alarm to the CPU. When used
with a PACSystems CPU, a Loss of Module fault is reported and all point faults corresponding to the
missing module will have the Fault Contact on.
• If an I/O module is configured but does not match the module present in the designated slot, the PNS
indicates the mismatch as part of the configuration sequence and the PNC generates an alarm to the
CPU. When used with a PACSystems CPU, a System Configuration Mismatch fault is reported and all
point faults corresponding to the module will have the Fault Contact on.
• If the I/O module configured matches the module installed in the assigned slot, but the module itself
has submodule options that relate to DIP Switch or jumper settings on the hardware and the physical
settings do not match the configuration, the PNS indicates a mismatch at the submodule level to the
PNC which generates an alarm to the CPU. When used with a PACSystems CPU, a System
Configuration Mismatch fault is reported and all point faults corresponding to the affected module will
have the Fault Contact on.
• If the physical module matches the configured module, but the configuration for the module is
unacceptable, the module itself rejects the configuration and energizes point faults until the
configuration is corrected. Many modules blink their OK LED in the event they reject the configuration.
Refer to Section 4.2.5.1, RX3i PROFINET Scanner Configuration Validation which specifies the rules
different modules use to validate their configuration.
• If an SFP module is configured but a different SFP is present (and that SFP is a supported SFP), the PNS
will allow the installed SFP to become operational. The PNS identifies the difference to the PNC in the
connection messaging sequence, and the PNC generates an alarm to the CPU. The SFP module
operates fully as if no difference had been detected. When used with a PACSystems CPU, a Valid
Module Substitution fault is reported.
• If an I/O module is installed but not included in the PNS configuration, no problem is reported. The
module is ignored by the PNS and defaults itself.
• If an SFP is installed but not included in the PNS configuration, default operation is enabled and active.
