System Manual, 05/2017, A5E31622160-AC
Procedure
1.
Add the new components to the system.
–
Insert new central modules in the rack.
–
Insert new modules in existing modular DP stations
–
Add new DP stations to existing DP master systems.
–
Insert new I/O modules in existing IO devices.
The IO devices to which I/O modules were added or from which I/O modules were
removed using H-CiR are highlighted in color.
–
Add new IO devices to existing IO controllers.
2.
Connect the required sensors and actuators to the new components.
Result
Inserting modules and I/O modules that are not yet configured does not affect the user
program. The same applies if you add DP stations or IO devices.
The fault-tolerant system continues to operate in the redundant system state.
New components are not yet addressed.
12.8.2
Change hardware configuration offline
Starting situation
The fault-tolerant system is operating in redundant system mode.
Procedure
1.
Perform all the modifications to the hardware configuration relating to the added hardware
offline. Assign appropriate icons to the new channels to be used.
2.
Compile the new hardware configuration, but do not load it into the target system just yet.
Result
The modified hardware configuration is in the PG/ES. The target system continues operation
with the old configuration in redundant system mode.
Configuring connections
The interconnections with added CPs must be configured on both connection partners after
you complete the HW modification.
