Siwarex WP521 Detect load cell error

Hello A_1986,

Normally the S7-program for the WP521 is used.

You can this S7-proramm on the internet:

https://support.industry.siemens.com/cs/ww/en/view/109736579

Here you can find the FB1552.

This FB handles the communication between the PLC and the WP521 module.

Into the Instance-DB of the FB1552 you can find the status of the load cell at:

Static -> s_IO_DATA -> SCALE_STATUS -> “CHANNEL_DISTURBED”

If you don’t want to use this FB, you have to disconnect/connect the load cell and try to find out the bit of the load cell by yourself.

Best regards

Siwarexi
