Transaction Timeouts
is the number of timeouts that occurred while the unit
was waiting for a response from a message. The DSLC control expects
responses only by the deadbus closing functions. If timeout errors occur during
deadbus closing, verify that network wiring installation is to specifications.
Otherwise, transaction timeout errors should not normally occur with DSLC
controls unless a non-standard custom installation has been done and another
device to which the DSLC control has been connected is not responding.
Rcv (Receive) Transactions Full
is the number of times an incoming message
was lost because no more transaction buffers were available. Frequent errors
indicate an overloaded network.
Lost Messages
is the number of times the application processor received more
messages at one time than it could process. It is possible in large systems that
enough DSLC controls may send out their load sharing information at nearly the
same time that lost messages may occur. Occasional errors will not affect
operation. If frequent errors occur in systems where a custom network
installation has been done, contact the installer. If no custom installation has
been done and sufficient errors are occurring to cause load sharing problems,
contact Woodward.
Missed Messages
is the number of times the network processor received more
messages at one time than it could process. It is possible that enough DSLC
controls may send out their load sharing information at nearly the same time that
Rcv Transaction Full errors may occur. Frequent errors indicate an overloaded
network.
NOTE
Missed and lost message errors will occur during power up when connected
to an active network. This is normal as messages are not processed during
power up diagnostics.
Last Reset Cause
is the method by which the Echelon Neuron network chip was
reset. After power-up, “Watchdog Reset” should initially be the indicated reset
cause. This will switch to “Cleared” on subsequent retrievals of the diagnostic
data. “External Reset” indicates the main DSLC control processor reset the
Neuron chip after losing communication with it. The number of times this occurs
is logged in Net(work) Interface Errors described below.
Network State
should always be “Configured, On-line”. Any other state indicates
either a defective DSLC control or an improper custom installation using a
network management tool.
Network Error Log
should always display “No Error”. Any logged error should
be reported to Woodward.
Net(work) Interface Errors
is the number of times the main DSLC control
processor had to reset the Neuron chip due to loss of communications. Errors
may occur during a custom installation and will cease when installation is
complete. Interface errors should not normally occur in operation, but occasional
errors that may be caused by extreme transient interference are possible and will
not affect control function. Frequent errors indicate extreme interference or a
defective DSLC control.
