By using the ADR function field device parameters are directly stored
inside the PLC DeviceNet scanner. The scanner must support this function.
An automatic recovery of
parameters during a device
exchange is possible
Activating ADR:
Go to scanner
Properties -> ADR
1. “Enable ADR”
2. “Load Device Config”
3. “Configuration
Recovery”

Tip Tip
IDLE mode:
Defines the status of output
signals during the connection
to a PLC which is
actually stopped or in
programming mode
FAULT mode:
Defines the status of output
signals during a network failure
when connected to a running PLC
The default setup defines all
output signals to the OFF
state during one of the modes
An optional channel based setup
can be made:
Value to OFF (default)
Value to ON
Hold Last State
! The internal CPX mapping
cannot be changed by the
configuration tools.

The “Status Bits” are 8 major signals which can be considered inside the
PLC program. They are accessed via the optional “Strobed connection”
Bit Diagnostic information Description
----------------------------------------------------------------------------------------------
0 Fault at valve Module type on which
1 Fault at output a fault has occurred
2 Fault at input
3 Fault on analogue/function module
----------------------------------------------------------------------------------------------
4 Under voltage Type of fault
5 Short circuit/overload
6 Wire fracture/open load
7 Other faults

Additional and advanced diagnostics can be read out with:
- Online mode of RSNetWorx
- Handheld unit CPX-MMI
Modular EDS makes an easier parameterisation possible. Just existing
parameters are visible. Parameters of complex modules and technology
modules are just listed in modular EDS. The I/O size is visible.
1. Install all EDS files from
the CPX modular EDS file
library
2. Change the DIP switches
Operating mode:
Remote I/O
Modular EDS
Attention:
- In combination with
RSNetWorx v.5 only
- The internal I/O mapping is
still the standard mapping
(see Step 4)

Additional diagnostics
and system data access
1. Explicit Messaging via DeviceNet
A library with objects for data access via DeviceNet is available.
The library includes objects (data groups), instances (module no)
and attributes (parameters) for almost all system data.
More details: Manual CPX-FB11 Attachments
2. Activating Status Interface or diagnostic Bits into the process data
Diagnostic Bits: Instead of using the status bits via
“Strobed connection”, an alternative mapping into
the process data is possible (2 Byte IN)
Status Interface: Allows an access to advanced CPX
data via a 2 Byte IN/OUT interface inside
the process data.
3. Using alternative tools
- RSNetWorx in online mode
- CPX-MMI - Handheld-tool which is optimised for use of CPX-Terminals
