Buen día. Soy integrador de Automatización. Un cliente intento actualizar el OS de un OPLC V350  pero éste se bloqueo. Ahora cuando se energiza, solo se oye un sonido intermitente y luego deja de sonar, pero la pantalla no enciende. Como puedo desbloquear el OPLC para actualizar el OS. el Serial del OPLC es LM00F10V7  V350-35-R2.  Gracias.

Good day. I am an Automation integrator. 
A client tried to update the OS of an OPLC V350 but it crashed. 
Now when it is energized, only a flashing sound is heard and then stops sounding, 
but the screen does not turn on. How can I unlock the OPLC to update the OS. 
The Serial of the OPLC is LM00F10V7 V350-35-R2. Thank you.


It probably had to do with how he connected to the PLC when he tried to update the OS.  Look at this post-
