Diagnostic Messages (Port 80)
When the SIMATIC PC is powered up, it runs a self–test (POST = Power On Self
Test). If the POST detects a fault, it outputs the sequence of beeps (beep code)
assigned for the fault. Each beep code consists of 2 x 2 sequences.
In addition, the individual self-test steps are output at I/O port 80h. The optional
SafeCard allows these outputs to be displayed in hex code at the front of the
device.
