(4) Do not make parameter setting via buffer memory and parameter setting from the RS-
232C port of the AJ71PB92D/A1SJ71PB92D at the same time.
If they are made simultaneously, ProfiMap which started parameter write earlier wins the
parameter write right after the operation mode is changed to the parameter setting mode, and
the other ProfiMap cannot perform parameter write and detects an error.
This status will be automatically cleared 15 seconds after completion of parameter write if
parameter write via the CPU module is valid, or 3 seconds after completion of parameter write
if parameter write from RS-232C is valid.
(5) Do not make simultaneous access to the AJ71PB92D/A1SJ71PB92D from multiple
ProfiMap's.
If such access is made, the AJ71PB92D/A1SJ71PB92D may not be accessed properly.
(6) If remote parameter setting is performed from MELSEC ProfiMap to the
AJ71PB92D/A1SJ71PB92D which is making data exchange, note that PROFIBUS data
exchange will stop during parameter setting.
(7) In a system where remote parameter setting is made from MELSEC ProfiMap, do not
execute the mode changing function using the program.
If the mode changing function is executed in the program, an interlock with the remote
parameter setting is not provided and therefore the mode may not be changed.
