How to switch on/off the service mode of WP321 by WRREC instruction?

Hi, Siwarexi

Can you tell me how to switch on/off the service mode of WP321 by WRREC instruction?

My configuration is S7-300 CPU plus ET200SP.

Thanks.

Split from Simulate SIWAREX WP321 with PLCSIM.

Hi Jimy,

I would recommend you to use the FB from the "Ready for use" project https://support.industry.siemens.com/cs/ww/en/view/94109373 .

There is also a small version of the FB that has reduced data needs.

In the manual chapter 11.6 it is explained how to send commands to the Siwarex WP321 with the FB https://support.industry.siemens.com/cs/ww/en/view/109760901 .

The command codes are explained in chapter 10.

If you don't want to use the FB it is more complicated: Data can be transferred with WRREC and RDREC blocks, with an hand shake via the periphery, direct command like "Service mode On", "taring"... are transferred via periphery with hand shake. 

To know more about that you might address to the Siwarex Support hotline.siwarex(at)siemens.com .
