Explanation
• If an error is detected by the error check for redundant system, the
corresponding bit shown below turns ON. That bit turns OFF when the
error is cleared after that.
b15 b2 b1 b0
Fixed to 0
SD1600
• If any of b0, b1, b2 and b15 is ON, the other bits are all OFF.
• In the debug mode, b0, b1, b2 and b15 are all OFF.
Stores the reasons for system switching.
• Stores the reasons for system switching into SD1601 of both systems
when system switching occarred.
• Initialized to 0 at power OFF to ON/reset to unreset.
• The following shows values stored into this register.
0: Initial value (System switching has not occurred)
1: Power off, Reset, H/W failure, WDT error,(*)
2: CPU stop error (except WDT)
3: System switching request by network module
16: System switching dedicated instruction
17: System switching request from GX Developer
*: When the system is switched by the power OFF/reset of the control
system, "1" is not stored into SD1601 of the new standby system.
• Stores the parameters for system switching dedicated instruction
SP.CONTSW.
(The parameters (SD1602) for SP.CONTSW are stored in both systems
A&B)
• SD1602 is only valid when "16" is stored in SD1601.
• This SD1602 is updated once system switch instruction SP.CONTSW is
activated.
• The error value sorted in BIN code.
• Stores SD0 of the other system CPU module
• Stores the date and time when diagnostics error occurred corresponding
to error code stored in SD1610.
• Data format is the same as SD1 to SD3.
• Also, stores the value to SD1 to SD3.
• Stores the category code corresponding to the error comment
information/individual information code.
• Data format is the same as SD4.
• Also, stores the value to SD4.
• Stores the common information corresponding to the error code stored
in this system CPU.
• Data composition is the same as SD5 to SD15.
• Also, stores the value to SD5 to SD15.
• Stores the individual information corresponding to the error code stored
in this system CPU.
• Data composition is the same as SD16 to SD26.
• Also, stores the value to SD16 to SD26.
• Stores the error code of the error to be cleared by clearing a standby
system error.
• Stores the error code of the error to be cleared into this register and turn
SM1649 from OFF to ON to clear the standby system error.
• The value in the lowest digit (1 place) of the error code is ignored when
stored into this regiser.
(By storing 4100 in this register and resetting the error, errors 4100 to
4109 can be cleared.)
