Diagnostic information detection signals (Un\G2.b1) and (Un\G0.b1)
[Processing when 'Diagnostic information detection signal' (Un\G0.b1) turns on]
After the time that is specified in 'Diagnostic information non-notification time setting area' (Un\G2084) has elapsed,
'Diagnostic information detection signal' (Un\G0.b1) turns on if a communications error is detected.
Once 'Diagnostic information detection signal' (Un\G0.b1) turns on, the following processing takes place.
• BF LED turns on.
• The diagnostic information is stored in 'Diagnostic information area' (Un\G23072 to Un\G23199).
• The extended diagnostic information is stored in 'Extended diagnostic information area' (Un\G23328 to Un\G23454).
• Bit in 'Slave status area (Diagnostic information detection)' (Un\G23056 to Un\G23060) relevant to the station that sent the
diagnostic information turns on.
• an error information of FX5-DP-M is stored into 'Local station error information area' (Un\G23071).
[Processing when 'Diagnostic information detection reset request signal' (Un\G2.b1) turns on.]
Turning on 'Diagnostic information detection reset request signal' (Un\G2.b1) causes 'Diagnostic information detection signal'
(Un\G0.b1) to turn off.
The following processing takes place when 'Diagnostic information detection signal' (Un\G0.b1) turns off.
• BF LED turns off.
• Bit in 'Slave status area (Diagnostic information detection)' (Un\G23056 to Un\G23060) relevant to the station that sent the
diagnostic information turns off.
When 'Diagnostic information detection reset request signal' (Un\G2.b1) is on, occurrence of another piece of diagnostic
information leads to the following state.
• 'Diagnostic information detection signal' (Un\G0.b1) does not turn on.
• BF LED does not turn on.
• Bit in 'Slave status area (Diagnostic information detection)' (Un\G23056 to Un\G23060) relevant to the station that sent the
diagnostic information does not turn on.
After 'Diagnostic information detection signal' (Un\G0.b1) turns off, take action against the cause of the error and turn off
'Diagnostic information detection reset request signal' (Un\G2.b1).
[Processing when 'Diagnostic information detection reset request signal' (Un\G2.b1) turns off.]
After 'Diagnostic information detection reset request signal' (Un\G2.b1) is turned off, the FX5-DP-M rechecks diagnostic
information.
If diagnostic information has been generated, the bits corresponding to 'Slave status area (Diagnostic information detection)'
(Un\G23056 to Un\G23060), 'Diagnostic information detection signal' (Un\G0.b1) and BF LED turn on and the following
processing takes place.
Turning on 'Diagnostic information detection reset request signal' (Un\G2.b1) does not clear the following
information.
To clear the information, turn on 'Diagnostic information area clear request signal' (Un\G2.b2).
• 'Diagnostic information area' (Un\G23072 to Un\G23199)
• 'Extended diagnostic information area' (Un\G23328 to Un\G23454)
• 'Local station error information area' (Un\G23071)
