[Global control failed signal' (Un\G0.b5)]
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.
If 'Global control failed signal' (Un\G0.b5) is on, this indicates that execution of the global control function has been completed
with an error.
Take action against the cause of the error and retry the global control function.
When 'Global control failed signal' (Un\G0.b5) is on, if DP-Slaves have already I/O data, the DP-Slave holds the data.
Turning off 'Global control request signal' (Un\G2.b4) causes 'Global control failed signal' (Un\G0.b5) to turn off.
Precautions
The global control function cannot be executed with the Acyclic communication function. When used in conjunction with these
functions, configure an interlock circuit in the program.

Extended diagnostic information read signals (Un\G2.b6) and (Un\G0.b6)
'Extended diagnostic information read request signal' (Un\G2.b6) is turned on when extended diagnostic information on a
specified FDL address is acquired. The FDL address is specified in 'Extended diagnostic information read request area'
(Un\G23456).
Turning on 'Extended diagnostic information read request signal' (Un\G2.b6) causes information in 'Extended diagnostic
information read response area' (Un\G23457 to Un\G23583) to be cleared.
After 'Extended diagnostic information read request signal' (Un\G2.b6) is turned on and extended diagnostic information on
the specified FDL address is acquired, 'Extended diagnostic information read response signal' (Un\G0.b6) turns on.
After 'Extended diagnostic information read response signal' (Un\G0.b6) turns on, 'Extended diagnostic information read
request signal' (Un\G2.b6) is turned off.
Turning off 'Extended diagnostic information read request signal' (Un\G2.b6) causes 'Extended diagnostic information read
response signal' (Un\G0.b6) to turn off.
