Definition of Process Networks
Enterprise Networks - protocols that focus on IT
applications (LAN, WAN, Ethernet) Control
Networks - protocols typically used to connect
controllers and I/O systems (ControlNet,
Ethernet/IP, FF-HSE, Modbus, Profibus-DP)Device
Networks - protocols originally focused on
process instrumentation (Foundation Fieldbus-H1,
HART, Profibus-PA) Sensor Networks - protocols
initially designed to support discrete I/O
(AS-I, CAN, DeviceNet, Interbus,
LON) ProtocolsThe network type does not
necessarily define the protocol.Separation of
protocols and network type is often unclear, many
cross into several classifications.

UNIQUE COMMUNICATION SOLUTION The HART Protocol
supports two way digital communications and is
designed to complement traditional 4-20mA analog
signal.

c Connection Read Access
The HART I/O modules reside within a Logix PLC
chassis. The I/Os are fully ControlNet
compliant. This means data is accessed via -
scan-based communication - unconnected
messaging ( processor independent )
12
I/O Communications Scan-based
The modules are configured using RSLogix
5000 Scan based data is accessed via your ladder
logic using module tags.
You have access to Analog value/control Devic
e Information HART PV, SV, TV, FV HART
Packet Data Four user defined slot
variables You have access to key data which
updates automatically
13
I/O Communications Scan-based
Scan based data is accessed via your ladder logic
using module tags.
Note that the HART PV, SV, TV, FV are available
without the typical command / response dialog.

• The module will accept and queue unconnected
  message requests.
• These messages may be generated by
• Message block in your ladder logic
• Your Application Layer

Commissioning
Quickly verify and document device configuration
and calibration, assure the integrity of wiring,
and confirm the operational capability of every
control loop all from one central
location. Verify and tune valve performance by
performing loop checks, via the network, and read
back position. Generate and archive system
configuration data more quickly.
