sensor will not be recorded
If recorded values for a sensor are all zero or some incorrect value, even when you know the
input levels are correct, then there is probably some error in the processing. Use the inputs
menu to first examine raw values and compare them to the converted values. If the wrong
processing is selected and/or the processing coefficients are incorrect, the converted value will
not be correct. If the converted value is correct, check the processing selected for the output.
If the 8310 appears to be skipping recording cycles then the problem is probably in the setup of
the measurement time or Interval. When you set up a measurement, remember that the timing
is ultimately limited by the time it takes to measure the specific sensor. Some sensors can be
measured in a fraction of a second while others take seconds or even minutes to complete. If
you have a schedule that does not provide adequate time for the measurement to complete,
the system can skip measurements.
LOS Radio Communications Problems
LOS radio communications problems are difficult to solve because of the number of factors that
can cause problems. This list includes:
setup errors
radio frequency off
radio transmitter deviation too high/low
radio/modem mismatch
antenna/cable problems
path problems
interference problems.
The place to start to troubleshoot radios is the 8310 itself. The 8310 maintains communications
statistics giving the number of messages received and transmitted and the number of failures.
These statistics can be viewed from the Diagnostics/Communications/COMx RADIO/ Test menu:
A typical report will be:
Radio: RX 155/541, 15 bad TX: 155, 10 bad
The first number following RX (the 155 in the example) is the number of messages the 8310
received that were directed to its Station ID. If this number is 0, the 8310 has not received any
messages with its ID. The second number (541) gives the total number of messages received.
This count includes messages that were addressed to other stations. The third number gives the
number of messages that were received, but had errors indicating a corruption of the message.
The numbers following TX give the number of transmissions that succeeded number of attempts
and the number bad.
When you have communications problems you should note these numbers and decide what
they tell you about the problem. Sometimes the answer will be clear just by looking at these
