Saving Variables

Since battery-backed RAM isn't an option for Clippers, along with other controllers, is it OK it issue a CMD "sav" from within a PLC(as a one shot) when you want to save variables? I am currently saving variable with a PC based application using pcommserver, but am looking to eliminate the PC, and just have a connection to an HMI or A-B PLC.

Issuing a CMD"SAVE" from a PLC is one possibility, but this process takes a few seconds. If the number of parameters you want to save is limited, it is preferred to use FSAVE and FREAD commands for saving a smaller portion of P-variables to flash in just a few milliseconds.
