7.9 Module replacement
5. Connect the module.
6. Insert the memory module with the existing configuration data.
Note
Do not connect a memory module with released configuration to a 3RK3 central unit of
another type.
The released configuration on the memory module depends on the 3RK3 central unit. For
example, the configuration released on an MSS 3RK3 Basic cannot be interpreted by an
MSS 3RK3 Advanced, or vice versa. The same applies to all other 3RK3 central units. When the
memory module is plugged into a 3RK3 central unit of another type, the configuration
release is canceled. The configuration may have to be adapted and released again.
System restart after module replacement
Can Cause Death, Serious Injury, or Property Damage.
After the supply voltage has been applied, the new 3RK3 central unit checks whether the
expanded hardware configuration matches the device configuration. If there are no
discrepancies, the system re-enters safety mode and the safety program is executed.
Take appropriate measures (e.g. start button with monitored starting) to prevent unintentional
restarting and to ensure a defined start of the system.
Replacing expansion modules/DP interface
Note
Only replace a defective module with a module of an identical type.
1. Disconnect the defective module at the terminals.
2. Remove the defective module.
3. Install the new module.
4. Connect the module.
