Store and load a project by using a memory card Chapter 1

Figure 1: Load and Update Examples on the Status Display

When the controller loads a project from a memory card, it:

• Logs a minor fault (type 7, code 49).

• Sets the FaultLog object, MinorFaultBits attribute, bit 7.

If you want your project to flag that it loaded from a memory card, use this logic.

On the first scan of the project (S:FS is on), the GSV instruction gets the FaultLog

object, MinorFaultBits attribute, and stores the value in minor_fault_bits. If bit 7

is on, the controller loaded the project from its memory card.

Where Is

Minor_fault_bits Tag that stores the FaultLog object, MinorFaultBits attribute. Data type is

DINT.

NVM_load Tag that indicates that the controller loaded the project from its memory

card.

Check for a load
