Replacing A Defective Simatic Memory Card - Siemens SIMATIC S7-1500 System Manual

Maintenance
15.1 Replacing system components
3. Reconnect all connectors you have previously removed.
4. You use the "PUSH" button to open the bottom cover.
5. Insert the SIMATIC Memory Card in the slot.
6. Switch the power supply back on.
Following a module replacement, the CPU operates with the configured start values.
SINAMICS Integrated detects a module replacement on the basis of the new SIMATIC Drive
Controller serial number. Following POWER ON, the NVRAM of the SINAMICS Integrated is
cleared and the NVRAM data is then loaded from the memory card.
Note
Make sure that the new SIMATIC Drive Controller has the same or a higher main firmware
version for CPU and SINAMICS Integrated .
If the main SINAMICS firmware version is higher, you will need to upgrade your project to the
relevant SINAMICS version to ensure that you can still go online with your project on
SINAMICS Integrated. Alternatively, you can downgrade the SINAMICS firmware main version
of a new SIMATIC Drive Controller back to the configured version.
Note
Setting up copy protection
For code blocks, you can set up copy protection (Page 254) that binds execution of the blocks
to a specific CPU or a specific memory card on the basis of the serial number. In such cases, a
substitute controller cannot be used without additional measures being taken.
15.1.2

Replacing a defective SIMATIC memory card

Initial situation
Possible error scenario if the SIMATIC Memory Card of a CPU is defective:
• System diagnostics reports a system error.
• The CPU has switched to STOP.
• The RUN/STOP LED is yellow and the ERROR LED is flashing red.
Requirement
• Replacement is only possible if you have a suitable replacement card. The replacement
card can be a copy of the defective card or a new project card created using engineering.
• The new SIMATIC Memory Card must have sufficient memory for the project.
Note
For code blocks, you can set up copy protection (Page 254) that binds execution of the blocks
to a specific CPU or a specific memory card on the basis of the serial number. In such cases, a
replacement card cannot be used without additional measures being taken.
