1.
Diagnostic Result is the result of power up diagnostics. A value of 49
indicates no problems found. Any other value indicates an internal failure in
the microprocessor or memory.
2.
ROM Check Sum is the result of doing a “checksum” test on program
memory. This value is verified each time the control is powered up. This
number is for factory test only. A failure in the ROM checksum test will also
result in a Diagnostic Result other than 49.
3.
Active DSLCs is the number of DSLC controls currently powered on the
network. This value is used to verify that all DSLC controls in the network
are in communication with each other.
4.
Retrieve Net Status retrieves the network error statistics accumulators, the
cause of the last reset, the state of the node, and the last run-time error
logged. Pressing the “.” key will retrieve the current statistics which can be
observed with the following set points.
Transmission errors will occur on occasion. Frequent occurrence of
transmission errors (that is, several per minute) indicates an overloaded
network, faulty network wiring, or a defective control in the network.
Status information is used during network installation to verify correct
operation.
