Note
(1) An activated diagnostics mode reduces the available
address space in the PDO 4
Use of the diagnostics mode (status bits or I/O diagnostic
interface) occupies 16 I or 16 I/O bits in the PDO 4. In
combination with technology modules, it thus reduces the
number of I/O bits which are available for module commu
nication. In this way, the number of addressable modules
is reduced in favour of additional status or diagnostic in
formation.
Take account of this fact for the planning of your CPX ter
minal.
(2) Subsequent activation of the diagnostics mode
requires reconfiguration
The CPX-internal I/O image can be displaced during
subsequent activation of the diagnostics mode (status bits
or I/O diagnostics interface). Restart the CPX terminal with
Power OFF/ON.
