Hi all,

Setup:

TIA 15.1

S7-1511, ET200SP, TM WP321, SIWAREX DB

Issue:

After trying to setup the SIWAREX DB the module with user program the Siwarex wont respond anymore.

The Module was working fine and communicating as it should, but we added a SIWAREX DB and since that it wont take commands any more.

The CMD Code is written to the WP321 DR Instance and the trigger is high. but it wont respond, no Finished ok nor Finished Error. But i still can read out the Scale status and the process values from the instance.

I made 2 approaches one with the my user program which was working fine before we added the SIWAREX DB and with the ready to use program as sanity check, but the result remains the same.

But I can send commands thru RS485 and SIWATOOL V7 and the Module is still responding and accept the commands.

Thank you for the help
