2.6 Precautions for Configuring a System
(1) There are the following restrictions on the AJ71PB92D/A1SJ71PB92D according to the
applied CPU module and used configuration software.

*1: The software version usable by the AJ71PB92D/A1SJ71PB92D is AJ71PB92D (A or
later) or A1SJ71PB92D (E or later).
When A1SJ71PB92D (software version D or earlier) is used, write is disabled and the
max. data length is 32 bytes each for input and output.
(2) Precautions for using the parameters preset for extended service mode to operate the
module in normal service mode.
The following table gives the operating conditions (conditions per one slave station) for the time
when the parameters preset for the extended service mode are used to operate the
AJ71PB92D/A1SJ71PB92D preset for the normal service mode/extended service mode.

(3) In either of the following cases, the AJ71PB92D/A1SJ71PB92D buffer memory must be
accessed by a sequence program when the module ready signal X1D of the
AJ71PB92D/A1SJ71PB92D is ON.
•
The operation mode is changed using Y11/X11 in the sequence program.
•
Parameter setting is made with ProfiMap connected to other than the RS-232C port of
the AJ71PB92D/A1SJ71PB92D. (For example, parameter setting is made with ProfiMap
connected to the RS-422/RS-232 connector of the CPU module.)
If the buffer memory is accessed with the X1D status ignored, the CPU module may detect
the "SP UNIT DOWN" error, stopping the sequence operation.
