(11)Process control instructions
Meaning
• Specifies whether or not to hold the output value
OFF : No-hold
when a range over occurs for the S.IN instruction
ON : Hold
range check.
• Specifies whether or not the output value is held
OFF : No-hold
when a range over occurs for the S.OUT instruction
ON : Hold
range check.
(12)For redundant systems (Host system CPU information *1)
SM1510 to SM1599 are only valid for redundant systems.
All off for standalone systems.
Meaning
OFF : Redundant system
backup mode,
• Turns on when the operating mode is redundant
independent system
system separate.
ON : Redundant system
separate mode
OFF : System A fixed mode • Turns on when the start mode for a redundant
ON : Previous control system when the power is turned on is the previous
system latch mode control system latch mode.
OFF : Initial start • Turns on when the CPU module operation mode is
ON : Hot start hot start when the redundant system is started up.
• Distinguishes between system A and system B.
• If the tracking cable is disconnected, the system identification is held to the previous
state.
System A System B
SM1511 ON OFF

• Turns on when the CPU module operation mode is
OFF : Initial start
hot start when the redundant system is actually start
ON : Hot start
up.
OFF : Not in debug mode • Turns on when the redundant system operating
ON : Debug mode mode is set to debug mode.
• Turns on when the operation is hot start when the
OFF : Initial start
CPU module operation is switched for a redundant
ON : Hot start
system.
OFF : Output reset • Turns on when the output mode during a stop error is
ON : Output hold output hold.
OFF : Control system • Turns on when the CPU module operation system
ON : Standby system status is the standby system.
• Indicates operation system status.
• The bit status doesn't change if the tracking cable is disconnected while the
redundant system is operating
