Operating mode:
Remote Standard
I/O EDS
Setting up the network
configuration
1. A DeviceNet Scanner must exist in the network
e.g. 1756-DN ControlLogix, 1747-SDN SLC
The DeviceNet scanner is mapping the network to the PLC register
2. Editing the Scan list
DeviceNet Scanner ->
"Properties" -> Scan list
Add your device from the
“Available Devices” list to the
“Scanlist”
3. Setting up I/O Parameters
Scan list -> Device-> "Edit I/O Parameters…"
! A manual setup of input/output data size is necessary
(Polled, CoS or Cyclic)
Additional
Diagnostic
Bits:
- deactivated
Optional: Adding up 1 byte diagnostic data to the “Strobed” connection

1. Setting up the I/O connection to the DeviceNet scanner
2. Changing CPX parameters
3. Data-access in the network online modus
Usually the network consists of the DeviceNet scanner and the field
devices. Each device has its own address. The DeviceNet slaves have to be
mapped to the scanlist of the scanner.

identification of device status

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 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”

1 Fault at output a fault has occurred
2 Fault at input
3 Fault on analogue/function module

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)

(from R14, SW 25.04.05)
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
