"Online Tools" task card

Introduction
If an online connection exists to a CPU of the redundant system, the "Online Tools" task card
displays online information for the redundant system.
For a S7-1500R/H redundant system, "Online Tools" displays:
● 3 panes operator panel
● Cycle time
● Memory
R/H system operator panel
For the redundant system, the "R/H system operator panel" pane shows the:
● Current states of the LEDs of the primary CPU
● System state
● Status of which CPU is the primary CPU and which CPU is the backup CPU with their
current operating states
The "STOP R/H-System" button can be used to switch the S7-1500R/H system to the
system state STOP.
Note
Reaching RUN-Redundant system state
Note that you cannot switch the S7-1500R/H to RUN-Redundant system state using the R/H-
System operator panel. You reach the RUN-Redundant system state by switching the
operating state for each CPU to RUN in the operator panel of the respective CPU.
CPU operator panel
The two "CPU operator panel" panes show for the respective CPU of the redundant system:
● The role of the CPU, primary CPU or backup CPU
● The current states of the LEDs
● The operating state of the CPU
Use the "RUN / STOP" button to change the operating state for the respective CPU.
Use the "MRES" button to perform a memory rest for the CPU, under the following
conditions:
● Online connection to this CPU is available
● The CPU is in STOP operating state.
The switch position at the real CPU is displayed under "Mode selector".
