Reading "Net Weight" and "Gross Weight" in the same time from WP521

Dear Sirs

I have WP521 and SIEMENS S7-1500 CPU, and TP1200 Comfort Touch Scree

After I tare the scale, I would like to show the "Net Weight" and "Gross Weight" on the screen in the same time.

How can my CPU read the "Net Weight" and "Gross Weight" from WP521 in the same time ?

Best Regards

Dear Siwarexi 

How can  I send the DR14 to the WP521 module ? 

Please guide me.  I am trying to write the PLC program for sending DR14 to the WP521 module.

But don't know know to do.

Thank you.

Hello anuchisa,

I recommend to define into the DR14 the two process values:
- „1“ for the Gross weight
- „2“ for the Net weight
Write these values („1“ and „2“) into the DR14 to the parameters PROCESS_VALUE_1_SELECTION and PROCESS_VALUE_2_SELECTION.

Afterwards send this DR14 to the WP521 module.

After that, you can see into the Instance-DB of your WP521 module at the address:
s_IO_DATA. PROCESS_VAL_1 and s_IO_DATA. PROCESS_VAL_2 the Gross and the Net weight.

Best regards

Siwarexi
