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 logic 0 or
logic 1. If all status bits supply a logic 0, there is no error. If, on the other hand, a status bit supplies a
logic 1, there is an error. In order to make use of the status bits function, the bus module of the
system CPX-E must be configured accordingly.
The status bits are shown in the process image if this has been specified by selecting the catalogue
entry "E-PN [Status]" in the hardware configurator.
If different errors occur simultaneously on different module types, errors cannot be assigned. To
clearly determine errors, the I/O diagnostic interface can be used è 2.4.3 I/O Diagnostics Interface.
You can find detailed information about status bits in the "Description of system CPX-E"
