S7-1200 Can DB current values (monitor value) be saved to start values

Mike.Mc

I have 360 recipe values saved in a data block. Every time I make a change I have to go through all 360 values and compare the latest recipe data with the "start value" and adjust the start value so my download does not wipe out the recipe.

I would like to be able to upload the current DB values and save them in the "start values." Pl;ease see attached .jpg file.

Any ideas?

Great! That works. I have to open all arrays and highlight the entire "Snapshot" column. Then copy and paste to the "Start Value" column. It works online as well. The link you sent instructs the user to go offline before the copy/paste operation.

The link "apply monitor values as start values" is crash.

I need save the actual values from db on start values from db.

I'm using TIA Portal V13.

How i can do this?

Hello Mike.Mc,
You can do the same using the snapshot function. Check here for the steps on the same - apply monitor values as start values

Maybe you should consider using another method to solve this problem: "Initialize data values in "RUN" mode".  

Here a short description from the online help:

Setting data values during commissioning

Basic information on adjusting data values during commissioning

Introduction

During commissioning of a plant, data values have to be frequently adjusted in order to optimally adapt the program to the general operating conditions on site. The declaration table for data blocks offers the following functions for this purpose:

● Initialize data values in "RUN" mode

This function enables you to change data values online in order to quickly determine the optimum tag values.

● Transfer tag values from the online program to the offline program as start values

When you have determined the optimum tag values, you can apply these as start values in the offline program. This allows you to ensure that the program starts with the optimized values the next time it is loaded.

To use the function, first define specific tags as "Setting values" in the program. Setting values are the values that will probably have to be fine tuned during commissioning.

Here you can find the complete description of this feature:

Hello ,

Is there any way to automate this function in TIA portal, Like with a BLKMOV Function?

Thx
