Utilities - Diagnostic Test
A tick indicates that the diagnostic test has passed (is successful). The test for the RAM Chips is only carried
out after a cold start. The other diagnostic tests are continually updated as the RTU runs.
I/O Bus: Test is passed if an IO module is detected. If the CPU loses communications with an IO module or
is unable to detect an IO module, the IO bus is denoted as unknown (blank).
C/M Bus: (Communications Bus) Test is passed if a communications module is detected (such as an MC
module). If the CPU loses communications with a communications module or is unable to detect a
communications module, the C/M bus is denoted as unknown (blank).
Real Time Clock: Test is passed if the seconds field of the real time clock has changed within 2 seconds.
Otherwise displayed as failed.
RAM: Passed if the battery backed RAM is OK.
Selecting the Advanced button on the Diagnostic window displays the following information:
The Advanced Diagnostic window displays
the number of restarts (Watchdog Count) of
the RTU and the number of cold starts. The
Watchdog count is incremented each time
the RTU is powered up or the Watchdog
timer forces a restart or #YSYS.WARMST
is set using ladder logic. Both the Watchdog
Count and the Cold Start Count can be
reset to 0 by selecting the respective Reset
button.
