This flag is used when switching the system
in any of the following sources to determine
detected by new

[Reason(s) for system switching]
switching
• System switching with a programming tool
• System switching using dedicated
by new standby
instruction
system at system
• System switching by the intelligent function
switching
module
This relay stores whether to enable manual
system switching
switching using a programming tool or the
system switching instruction (SP.CONTSW).
system switching
This relay sets the behavior of the system
after the standby CPU in the separate mode
accessed the buffer memory of an intelligent
function module mounted on an extension
base unit.
• OFF: "OPERATION ERROR" (error code:
4112) is returned.
• ON: No processing
When SM1595 is turned on from off, memory
copying from the control system to the
standby system starts. Note that memory
copy
copy does not start even after SM1595 was
turned on from off if the I/O No. of the copy
initiated
destination (standby system CPU module:
3D1 ) is not stored in SD1595.

Explanation
(When Set)
• When data is
transferred based
on the tracking
setting of the
Redundant
parameter window,
the target block is
specified as
trigger.
• When "Do auto
forward Tracking
block No.1" is
selected for the S (Initial)/U
tracking setting,
SM1520 is turned
on by the system
at power-on or
when the system
is switched from
STOP to RUN. In
other cases,
SM1520 to
SM1583 are
turned on by the
user.
