Status bits

The system CPX-E provides 8 status bits for displaying global common diagnostic messages.
The status bits are configured like inputs and supply coded diagnostic information in the form of 0 or 1 signals. If all
status bits are supplying a 0 signal, there is no error. If, in contrast, a status bit supplies a 1 signal, there is a fault.
In order to make use of the status bits function, the bus module of the system CPX-E must be configured
accordingly.
If different errors occur simultaneously on different types of modules, errors cannot be distinguished.
The I/O diagnostic interface can be used to distinguish errors clearly è 2.4.3 I/O diagnostic interface.
You can find detailed information about status bits in the "Description of system CPX-E"
è 1.1 Further applicable documents.
2.4.3

I/O diagnostic interface

The system CPX-E provides an I/O diagnostic interface in the form of 16 input bits and 16 output bits for reading
detailed diagnostic information. The I/O diagnostic interface can be used, for example, to precisely determine the
module and channel on which an error has occurred. In order to make use of the I/O diagnostic interface, the bus
module of the system CPX-E must be configured accordingly.
You can find detailed information about the I/O diagnostics interface in the "Description of system CPX-E"

Remedy
–
• Check configuration of the system CPX-E;
it is possible that the system CPX-E is not
assigned to a master/scanner.
• Correct IP address.
• Check the physical connection to the
master/scanner.
–
–
• Check network connection.
• Check IP addressing settings.
