The memory card is an optional accessory for the UN120 and UN200 series PLCs. It is a removable, non-volatile memory used to store user files, program blocks, data blocks, system blocks, recipes, data records, and forced values. Programming or erasing operations can be performed on the memory card through the PLC menu in the programming software.

Memory card programming: It can upload program blocks, system blocks, data blocks, recipes, and data record configurations from the PLC to the memory card for storage.

Memory card erase: This function can delete all data on the memory card.

Application, please be aware!!!

✩If no memory card is inserted, clicking "Memory Card Programming" will result in the following:

When the above error message appears, check if the memory card is inserted into the PLC or if the memory card is making proper contact. You can remove the memory card and reinsert it into the corresponding slot on the PLC, or check if the memory card is listed in the programming software's resource manager.

✩ When inserting a memory card and clicking "Memory Card Programming", the following will occur:

If the PLC does not detect the memory card during the "Memory Card Programming" function or before the programming operation is completed, the following situation will occur:

This error message can occur not only because the PLC cannot recognize the memory card information, but also because the memory card previously stored PLC information. This error may also occur when the PLC version information of the last "memory card programming" operation is inconsistent with the PLC version information of the current "memory card programming" operation.

Therefore, to avoid the above situation, it is best to erase the memory card before each use of "memory card programming" and save important PLC projects elsewhere in advance to avoid PLC version information mismatch.

✩ During the "memory card" programming process, sometimes a power outage or malfunction may occur in the PLC. In this case, an error will occur when reading the memory card content. At this time, both the SF/DIAG and STOP lights of the PLC will be lit. The PLC information will be as follows:

We've been working on it. What's the current memory card support status?

PLCs that support 64K memory cards include UN124XP, UN224, UN284, UN224H, and UN286.

The UN200 series PLC supports 64K memory cards, and the maximum programmable single data record is 50K.

The UN120 series PLC supports 64K memory cards, and the maximum programmable single data record is 18K.

PLCs that support 64K memory cards cannot program non-existent program blocks and data blocks.
