Problem on siwarex WP321, value is always zero

Hi! 
I have this problem on siwarex WP321: Calibration (automatic) seems to be ok (finished_OK) on command 82 checked. But now the value is always zero! Leds are Ok on the module but still cannot read any value. 

Also, "ready to use" HMI cannot read ascii_value (empy field).

Could you help me? Im attaching DR34.

thanks a lot, regards, 

Esteban.

Hi TebiPor,

if you want to see the actual value in DR34 you have to read this with command 2034 in a cyclic way.

In the example project from here: https://support.industry.siemens.com/cs/ww/en/view/94109373 this is done with the help of the "CMD_HANDLING" block, that is called in OB30 "Cyclic interrupt", see screen shots "Call_CMD_HANDLING" and "CMD_HANDLING". If this is done you can enter command codes to "CMD_A" and "CMD_B", that will be executed in a cyclic way, see screen shot "CMD_2034". If this is done you see the command are executed in "s_CMD3" in a cyclic way. 

Anyway if you want to see the actual value you can also look into the "s_IO_DATA.PROCESS_VAL_1", with standard parametrized DR14, you will see the actual weight in this parameter, updated each OB1 call, without doing anything.

Hello, finally it worked! 
I went to see the installation and it was all wrong. Load cells were upside down so I got "Error 7007" every time for one silo and there were still mechanical stops supporting the load on the other silo so of course it will be always zero weight.

Thanks for your help.
