PLC Operations Menu
The structure of the PLC Operations menu and submenus are:
Submenu for PLC Operations: Start, Stop and Init:
Start, Stop, Init Screens Display
Fields Available
Description
Start PLC
Press <ENTER> to confirm Start.
Pressing <ENTER> starts the controller.
Stop PLC
Press <ENTER> to confirm Stop.
Pressing <ENTER> stops the controller.
Init PLC
Press <ENTER> to confirm Init.
Pressing <ENTER> initializes the controller.
On safety processors, this command is only available in the maintenance mode.

Description
Hot Standby State:
State
read-only
PRIMARY CPU
Controller serves as primary unit.
STANDBY CPU
Controller serves as standby unit.
Offline
Controller is neither primary nor standby unit.
Hot Standby Mode:
Mode
(modifiable only if the key switch is in the unlocked position)
RUN
STS steady
Controller is active and is either serving as primary PLC or able to take over the primary PLC role if needed.
STS flashing
Controller is transferring/updating. When the transfer is done, RUN stays on steady.
OFFLINE
STS steady
Controller is taken out of service without stopping it or disconnecting it from power.
If the controller is the primary PLC when the mode is changed to offline, control switches to the standby PLC.
If the standby PLC changes to offline, the primary PLC continues to operate without a backup.
STS flashing
Controller is transferring/updating.When the transfer is done, OFFLINE stays on steady.
Hot Standby Order:
A or B
(modifiable only if the key switch is in the unlocked position)
FIRST
Hot Standby power order
NOTE: To change the A/B order, confirm that the PLC is in STOP mode.
SECOND
Hot Standby Transfer:
-
(This menu option is enabled only when the key switch is in the unlocked position.)
Pressing the <ENTER> key confirms the transfer. The transfer initiates the request of a program update from the primary PLC. Pressing any other key cancels the transfer initiation and returns to the Hot Standby Transfer menu option screen.
NOTE: Transfer by keypad is based on %SW60.5 use: modifying %SW60.5 by application and requiring simultaneously a transfer by Keypad, could lead to some issues (no transfer or transfer retry).
Hot Standby Diag:
The order of diagnostic screen varies with the operation.
Halt
user task in halt mode
RIO fails
detected error reported by RIO head
HSBY fails
detected error reported by optical link
Stop
