虽然CP1430TF集成有RAM，没有flash卡实现其功能没有问题，但从工程的角度看，我认为配置FLASH卡应该是必需的。保存在RAM里的组态数据在实际应用中因PLC电池失效而丢失程序数据是很常见的。

QUESTION:
Do I have to use a memory card to operate the CP 1430 TCP and if so, which one?

ANSWER:
No, in principle you can also operate the CP 1430 TCP without a memory module, because the internal memory has sufficient capacity.
The disadvantage of this way of operating is that the project has to be reloaded explicitly if the backup battery fails or if you change modules.

If you use a memory card for the CP1430 TCP, then you need the SIMATIC memory card (256-Kbyte EPROM) - Order number.: 6ES5374-2KH21.

这方面CP1430TF与CP1430TCP是一样的！
