information detection signal (X01)
(a) The Diagnostic information detection signal (X01) turns ON when a
communication error is detected after the time preset in Diagnostic information
non-notification time setting area (Un\G2084) has elapsed.
The following processing is performed at the same time that the Diagnostic
information detection signal (X01) turns ON:
• The RSP ERR. LED turns ON.
• The diagnostic information is stored in the Diagnostic information area (for
mode 3) (Un\G23072 to Un\G23321).
The extended diagnostic information is stored in the Extended diagnostic
information area (for mode 3) (Un\G23328 to Un\G23454).
• The corresponding bit in the Slave status area (Diagnostic information
detection) (Un\G23056 to Un\G23064) of the station that sent the diagnostic
information turns ON.
• The error information of the QJ71PB92V is stored in the Local station error
information area (Un\G23071).
(b) Turning ON the Diagnostic information detection reset request signal (Y01) turns
OFF the Diagnostic information detection signal (X01).
The following processing is performed at the same time that the Diagnostic
information detection signal (X01) turns OFF:
• The RSP ERR. LED turns OFF.
• The corresponding bit in the slave status area (Diagnostic information
detection) (Un\G23056 to Un\G23064) of the station that sent the diagnostic
information turns ON.
(c) When new diagnostics information is generated while the Diagnostic information
detection reset request signal (Y01) is ON, the behavior is as follows:
• The Diagnostic information detection signal (X01) does not turn ON.
• The RSP ERR. LED does not turn ON.
• The corresponding bit in the Slave status area (Diagnostic information
detection) (Un\G23056 to Un\G23064) of the station that sent the diagnostic
information does not turn ON.
(d) After the Diagnostic information detection signal (X01) turns OFF, take actions for
the error cause and turn OFF the Diagnostic information detection reset request
signal (Y01).
