Frequently Asked Questions

What is the storage capacity of this card?

The 416NHM21234 is typically a 2MB or 4MB card, designed for the program sizes of legacy Modicon PLCs. The exact capacity is often defined by the ordering code.

Can I use it to run the PLC program directly?

No. This is a storage/memory card. The PLC's operating program runs from its internal RAM. This card is for backup, transfer, and additional data storage.

How do I transfer files to/from the card?

You need Schneider Electric programming software (Unity Pro, Concept) and, for network transfer, a Modbus Plus connection to the PLC. Files can also be transferred via the PLC's serial or USB port.

Is it compatible with Modicon M340 or M580 PLCs?

No. Modern controllers like the M340 and M580 use SD cards or internal flash memory. This PCMCIA card is for older Quantum and Premium platforms.

What does "Type 3 PNP" mean?

"Type 3" refers to the physical thickness of the PCMCIA card. "PNP" stands for Plug-and-Play, meaning it does not require external configuration or drivers when inserted into a compatible slot.
