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.

Hello Please have a look on the attached project. And please change extension from *.ZIP to *.RAR I have created another symbolic IO field for you and it write in MW50. Then in code, you will prepare only one network If MW 50 = 0 => stop the motor If MW 50 = 1 => start the motor Hope this helps.

Hello, For the sake of saving resources, if you have two operations (start & stop), it is better to use bool tag (DB1.DBX4.0 = 0 > stop, DB1.DBX4.0 = 1 > start). At your plc: [code]A DB1.DBX 4.0 = Q 4.0[/code] Have a look at my attached example (rename to .RAR) Rgs AttachmentScada example 3.zip (200 Downloads) |
