Tag Description (if = 1)
AuxiliaryCommunicationsProcessor
Aux Processor Status
Container value allows access to hidden tags. The hidden tags provide no user actionable information. They are
provided to assist device diagnostics only.
See the Assembly Object (class code 0x04), on page 517, for the assembly members and bit assignments.
ConnectionFaulted
Connection Faulted
Set when there is no connection to the module.
ConnectionFaulted is set by the controller when the connection to the module is lost.
NetworkFault
Network Fault
This tag is managed by the controller and the module:
• NetworkFault is set by the controller coincident with setting the ConnectionFault.
• The module sets NetworkFault when:
– The device is powered off
– No IP address is configured
– A Network cable is not detected
– An exclusive owner connection has timed out
If NetworkFault is set by the module*, it is unlikely to be observed by the controller as it is likely that the
connection is also faulted.
*The module event log records when the tag was set and the reason why.
NetworkAddressFault
Network Address Fault
Indicates an IP addressing conflict (address in use by another device). When set, this error contributes to an “EIP
communication fail.” in the context of a module fault relay.
RecoverableFault
Recoverable Fault
Can be cleared by updating the configuration or cycling of power.
NonRecoverableFault
Non Recoverable Fault
If cycling power does not clear the tag, then a non-recoverable hardware problem is indicated.
RedundantPowerFault
Redundant Power Fault
One of the power supply inputs is at less than 17 Volts and the module is configured for redundant power in Module
Definition (see Power Supply
, page 99).
Tag Description (if = 1)
