Hi, when I sad: "generally, it is not necessary to copy the actual values to initial values, " it was the initial values never goes to the CPU, just the actual values. Normally, programer mount a empyt DB for machine data, for example. In start up it full the values on the VAT." |

Hello mynamesnotnick, who cares about the initial values? In the FAQ UMENCHO linked to is written that they aren't used by the CPU so only you need are the actual values to save in load memory and/or offline program folder which is such easy! Didn't you mistakenly twisted in mind the initial values with the first time declared actual values in offline? Regards Sydney |

So the whole point is why does Siemens even show an Initial value at all. This just confuses peoplethat are familar with other PLCsoftware. I say just display what the actual value is period. |

HELLO, the link for the FAQ is not anymore valid. I need to upgrade the firmware of a 4142gx03oab0 cpu but prior to this I need to save all current data onto their initial value. Thanks for your help in advance |
