Diagnostics via status bits

3-12
The CPX terminal provides 8 status bits if you activate this
function using DIL switches (see section 1.4.2) – assuming
the corresponding PLC hardware configuration (see Tab. 1/3).
Observe also the continued explanations for configuration in
section 2.6.2.
The status bits are used for displaying common diagnostics
messages (global error messages). The status bits are con-
figured like inputs; you can select the address freely during
the configuration.
If all status bits supply a logic 0, no error will be registered.
