SIMATIC S7, Micro Memory Card for S7-300/C7/ET 200, 3, 3V Nflash, 8 MB
Q: When should I choose the 8 MB card over the 4 MB version?A: Choose the 8 MB card if your project involves large data blocks, extensive recipe management, or if you are using the PLC for local data logging of process values over a long period.
Q: Can this card be used in an S7-400 or S7-1500?A: No. S7-400 uses large PCMCIA-style cards, and S7-1500 uses the SMC format. This card is only for S7-300 and compatible distributed I/O stations.
Q: What is the risk of using a non-original card?A: Cheap third-party cards often fail to maintain the strict timing required for PLC load memory, which can cause unexpected CPU stops and data loss during operation.
