F-14 Supported Emulated Block Transfer Commands: NVS Functions
NVS Functions
NVS (Non-Volatile Storage) Functions activates an NVS function.
PLC Block Transfer Emulation Instruction Data
PLC request instruction length: 4 words
Drive response instruction length: 3 words
Message Operation
The NVS storage function allows three different message requests:
• NVS Save saves parameter information from the working
memory or RAM to NVS Storage.
• NVS Recall retrieves the last saved data from NVS Storage and
places it in the working memory or RAM.
• NVS Default Initialize clears the RAM and NVS Storage and sets
all parameter values to default.
If an error has occurred, response word 1 returns a value of -31998.
Example
This example requests the NVS Storage Save function be performed.
