Parameter
|
Data type
|
Description
|
---|---|---|
TO_REV1
|
Describes the first reverse transfer register if this PLC is the Standby PLC. Data in this register are transferred from the Standby CPU to the Primary CPU at each scan.
|
|
TO_REV2
|
INT
|
Describes the second reverse transfer register if this PLC is the Standby CPU. Data in this register are transferred from the Standby CPU to the Primary CPU at each scan.

Parameter
|
Data type
|
Description
|
---|---|---|
HSBY
|
1 = This is a Hot Standby configuration.
0 = This is not a Hot Standby configuration.
|
|
PRY
|
BOOL
|
1 = This PLC is the Primary CPU PLC.
0 = This PLC is not the Primary CPU PLC.
|
SBY
|
BOOL
|
1 = This PLC is the Standby CPU PLC.
1 = This PLC is not the Standby CPU PLC.
|
FR_REV1
|
INT
|
Content of first reverse transfer register %SW62. Output only if HSBY is 1.
|
FR_REV2
|
INT
|
Content of second reverse transfer register %SW63. Output only if HSBY is 1.
