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.
