Siemens BLKMOVE with nested structure

[JDCROCKETT724]

I am trying to copy settings from a DB that stores two different models worth of settings in it to a particular DB.

This is how it works:
I have 3 root structures within my DB. One is the current settings, one is model A and the other is model B. When I change models I copy the specified model to the "Current" settings. These settings are then used by the machine to work.

Within the "Current" struct there are 4 identical structures that need to be copied to their respective DB's. These structures are called INJ1_Settings, INJ2_Settings, INJ3_Settings, INJ4_Settings. There are 9 REAL data types in each one. So I wish to copy INJ1_Settings in the "Current" struct to DB15 which has a struct of the same size and data types as INJ1_Settings. Then copy INJ2_Settings in the "Current" struct to DB16 and so forth.

My Problem:
When triggering the BLKMOV with a one shot the settings in INJ4 are getting transferred to DB15 and NOT the INJ1 settings that I have as the SRCBLK.



Any ideas why a struct 3 away from the one I specified in the BLKMOV is being transferred instead of the one I called for?

Thanks in advance

Edit: I found if I hold the enable on the BLKMOV on instead of triggering it with a one shot that it works as it should. However, I need to keep that as a one shot copy if possible.

SFC20 should finish in one instance. No need to keep the EN for a longer time.
The only thing that should be able to mess it up is if the SFC20 is interrutpted, by a HW interrupt or timed interrupt. Is that a possibility ?

Apart from that I suggest 2 things.
1. Make a UDT with the structure that is used several places, then define the data by the UDT.
2. Run a block consistency check.
Maybe that clears it up.

Do you enter Any data type (P#DB6.DBX0.0 REAL 9) and input automatically changes to what is shown in a screenshot?

 

[L D[AR2P#0.0]]

Copy the relevant blocks to a library and post the archived library for analysis.

You don't appear to have specified how much data to move after your pointer. I always specify mine in bytes but I suppose it would work as Marcius suggests with REAL 9.

 

[L D[AR2P#0.0]]

If you enter a named variable for an any pointer parameter, the editor will generate the pointer format for the call, but will show it to you as the variable name.

Ok. I was copying the relevant blocks over to another program for offline and PLC simulation analysis for you siemens pros, but now the simulation works just the way I want it to. So something is going on different between my cleaned up program to post here and my actual program.

Alright. This is a little embarrassing. It must have been an off day for me yesterday. I found some copy paste errors that I thought I got rid of and didn't look back on them. So I was copying to my INJ1 settings 4 times with the last one being from INJ4. Thank you for all your responses, and sorry to waste your time.

You won't be the first nor will you be the last to do such things. At least you found it and it is now working.
