    holzher unimaster 7226

    I'm having a problem where the machine keeps registering a communication error. The profibus is losing communication with the electrical cabinet. I've already checked to make sure that I have a good wire connection at the terminals but I can't clear the error... i'm getting an error code e-a599 on the profibus when it loses communication....does anyone know what that error code means or how I can restore communication to the electrical cabinet?

    Hello,
