3.3 Diagnostics via status bits
The CPX terminal provides 8 status bits if youactivatethis
function using DIL switches (see section 1.2.2).
The status bits are used for displaying common diagnostics
messages (global error messages). Status bits are configured
like inputs. If the status bits function is activated, it occupies
the first 16 inputs in the address range (8 inputs or 8 bits
remain unused; see Tab.1/2 or Tab.2/1).
Please note
Note the instructions on addressing and configuration in
the sections 2.3 and 2.4.
The following table provides an overview of the available
diagnostic information.
