Diagnostic information area clear signals (Un\G2.b2) and (Un\G0.b2)
'Diagnostic information area clear request signal' (Un\G2.b2) is turned on when the following information is cleared.
• 'Diagnostic information area' (Un\G23072 to Un\G23199)
• 'Extended diagnostic information area' (Un\G23328 to Un\G23454)
• 'Local station error information area' (Un\G23071)
After 'Diagnostic information area clear request signal '(Un\G2.b2) is turned on and the processing above is completed,
'Diagnostic information area cleared signal' (Un\G0.b2) turns on.
When 'Diagnostic information area clear request signal' (Un\G2.b2) is on, if another piece of diagnostic information is
generated, the following information remains cleared. (Diagnostic information, extended diagnostic information, and own
station error information will not be stored.)
• 'Diagnostic information area' (Un\G23072 to Un\G23199)
• 'Extended diagnostic information area' (Un\G23328 to Un\G23454)
• 'Local station error information area' (Un\G23071)
After 'Diagnostic information area cleared signal' (Un\G0.b2) turns on, 'Diagnostic information area clear request signal'
(Un\G2.b2) is turned off.
Taking action against the error cause and turning off 'Diagnostic information area clear request signal' (Un\G2.b2) causes
'Diagnostic information area cleared signal' (Un\G0.b2) to turn off.
After 'Diagnostic information area clear request signal' (Un\G2.b2) is turned off, the FX5-DP-M rechecks diagnostic
information.
With any piece of diagnostic information generated, diagnostic information, extended diagnostic information, and own station
error information are stored in the buffer memory.

Global control functions (Un\G2.b4), (Un\G0.b4), and (Un\G0.b5)
[Global control request signal' (Un\G2.b4) and 'Global control completed signal' (Un\G0.b4)]
'Global control request signal' (Un\G2.b4) is turned on when the global control function is executed.
After 'Global control request signal' (Un\G2.b4) is turned on and the global control function processing is completed, 'Global
control completed signal' (Un\G0.b4) turns on.
After 'Global control completed signal' (Un\G0.b4) turns on, 'Global control request signal' (Un\G2.b4) is turned off.
Turning off 'Global control request signal' (Un\G2.b4) causes 'Global control completed signal' (Un\G0.b4) to turn off.
'Global control request signal' (Un\G2.b4) is turned on when 'Data exchange start completed signal' (Un\G0.b0) is on.
When 'Data exchange start completed signal' (Un\G0.b0) is off, if 'Global control request signal' (Un\G2.b4) is turned on, both
'Global control completed signal' (Un\G0.b4) and 'Global control failed signal' (Un\G0.b5) turn on.
