Diagnostic information invalid setting area
■
Diagnostic information invalid setting area (Un\G2080)
This area sets a value to mask (invalidate) pieces of diagnostic information sent from DP-Slaves during communications.
• 0: Validates the diagnostic information.
• 1: Invalidates the diagnostic information.
The FX5-DP-M does not recognize as diagnostic information the diagnostic information relevant to bits that is generated at a
DP-Slave and results in the following status.
• 'Diagnostic information detection signal' (Un\G0.b1) does not turn on.
• BF LED does not turn on.
• The error code and detailed data are not stored in 'Diagnostic information area' (Un\G23072 to Un\G23199) or '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 does not turn on.
Configure the values of 'Diagnostic information invalid setting area' (Un\G2080) when 'Data exchange start
request signal' (Un\G2.b0) is off.
Any value configured while 'Data exchange start request signal' (Un\G2.b0) is on will be ignored.
