Diagnostics events include errors in a digital function in the C7, system
errors in the C7 caused, for example, by programming errors or operating
mode transitions.
The diagnostic functions cover the entire system diagnostics and include the
detection, evaluation and signaling of errors/faults within the C7.
Modules with diagnostic capability signal detected system errors to the –>
C7 CPU using diagnostics interrupts.

System diagnostics
E
Electrical connection (equipotential bonding conductor) that keeps the bodies
of electrical devices to the same or approximately the same potential as
extraneous conducting bodies to prevent interference or hazardous voltages
arising between the bodies.
Error display is one of the possible responses of the operating system to
runtime errors. The other possible responses are: Error response in the user
program, STOP status of the C7 CPU.
F
FEPROMs correspond in their function to the electrically erasable EEPROMs
but they can be erased much faster (FEPROM = flash erasable programmable
read-only memory)
The following data can be stored in a flash EPROM safe from power failure:
S
The –> user program
S
The –> parameters that determine the behavior of the –> C7 CPU and the
I/O functions of the C7.
