APPENDICES
*2: The module whose first 5 digits of serial No. is "09012" or later.
(14)For redundant system (Other system CPU information *1)
SM1600 to SM1650 only valid for the CPU redundant system backup mode, so they
cannot be refreshed during the separate mode.
Either the backup mode or the separate mode is valid for the SM4651 to SM1699.
SM1600 to SM1699 are all turned off for stand-alone system.
*1 Stores other system CPU diagnostic information and system information.
*2 This shows the special relay(SM ) for the host system CPU.

Setting to access
extension base unit of
standby system CPU
OFF : Error
ON : Ignored
Sets the operation for the case accessing buffer
memory of the intelligent function module mounted on
the extension base unit from the standby system CPU
in separate mode.
OFF : “OPERATION ERROR” (error code: 4112) will be
returned when accessing buffer memory of the
intelligent function module on the extension base
unit from the standby system CPU.
ON : No processing is performed when accessing
buffer memory of intelligent function module on
the extension base unit from the standby system
CPU.

Memory copy to other
system start flag
OFF : Start memory copy
ON : No memory copy
initiated
• When SM1595 is turned from OFF to ON, memory
copy from control system to standby system starts.
Note that when SM1595 is turned from OFF to ON,
memory copy dos not start if the I/O No. of the copy
destination (standby system CPU module: 3D1

) is
not stored in SD1595.
