Hello Ayman, very nice link! Thank you for sharing. But I understand the Problem of xuanphuin a different way.... Would you please read the basic question again to tell me if i am wrong...? Thank you,Jürgenfor your notice. My reply here is you already solved the problem and your code provided should work if the symbolic IO field is done correcty. If problem still happen, may be other network in PLC program write inDB1.DBX 4.0 or DB1 DBX 4.1 or even in Q0.0. So, you have to use cross reference to check. Monitoring using VAT will help. Open a VAT while you are changing the selection of symbolic IO field and see what is happening withDB1.DBX 4.0, DB1 DBX 4.1 and Q0.0. Hope this helps.
