2.1 INTRODUCTION TO MODEL 1056 WITH PROFIBUS

Profibus configurations of Model 1056 (1056-0X-2X-3X-DP) allow digital communications with a Profibus class 1
master to read measured process variables.

Profibus configured Model 1056 units support communications with a Profibus master using any combination of
dual measurement inputs.

Profibus configured Model 1056 units include the following basic components:

1. A plug-in communications board in the card cage slot nearest the Power Supply

2. An M12 cable assembly and metal fitting for connection to the Profibus network (optional)

3. An IPL (Initial program load) for the 1056 main board to add Profibus functionality

4. RAII1056.GSD file for use with a Class 1 master. Must be downloaded from Rosemount Analytical web

2.2 OVERVIEW OF PROFIBUS-DP

Fieldbus networks are serial communication systems (see Figure 1) used to pass data signals between host
systems and distributed peripheral equipment. The principal advantages of such a system are reduced cabling,
commissioning and maintenance costs when compared with conventional architectures. A pair of wires is all that
is required to transmit all the necessary signals (inputs, outputs, settings, diagnostics, etc.).

2.3 INTRODUCTION TO PROFIBUS - GENERAL

Profibus is an open FIELDBUS standard complying with the harmonized European standard EN 50170. It permits
devices from different manufacturers to communicate with one another without the need for specialized interfaces.
It may be used equally well for high speed, time critical data transmission or for transfers of large quantities of
complex data signals.

Profibus exists in three versions or protocol architectures.

• PROFIBUS-DP (Decentralized Periphery), is designed for communications
between automation systems and distributed input/output (I/O) devices. It may be
used to replace 24V or 0-20mA parallel transmission systems.

• PROFIBUS-PA (Process Automation) is designed to meet the specific needs of
process engineering industries for use in explosion-proof and potentially explosive
areas. Sensors and actuators are connected together on the same bus, including
in dangerous within hazardous intrinsically safe zones. Both the signal data and
the power signals travel over a two-wire link in compliance with International
standard, IEC 1158-2.

• PROFIBUS-FMS (Fieldbus Message Specification) is primarily intended for cell
management. Its sophisticated functions allow it to cover a wide range of
applications. It may be used for both complex and high volume data exchanges.

3.3 WIRING TO A PROFIBUS NETWORK WITH AN M12 CABLE ASSEMBLY

MODEL 1056DP SECTION 3.0

INSTALLATION AND WIRING

This section outlines recommended methods of wiring Model 1056 units which include a Profibus DP digital com­munications board. The conventional method is to wire a standard purple Profibus cable directly to the instru­ment. Alternatively, Profibus-configured Model 1056 units can be wired to a Profibus network using an M12 adap­tor cable assembly. The M12 adaptor cable assembly offered by Rosemount Analytical is an ordering option and
is not provided with the Model 1056-DP unit. See Sec. 6.0 Profibus Accessories for parts ordering information.
Additional accessories are also available to support necessary connections to a Profibus network and Profibus
master.

3.1 PROFIBUS BOARD

Profibus-configured Model 1056 units (Model number 1056-0X-2X-3X-DP) include a pre-installed Profibus com­munications board and a ribbon cable. A 4-lead removable terminal block is installed on the Profibus board to allow
wiring to a Profibus network.

Profibus-configured Model 1056 units also include a pre-installed 10-lead ribbon cable that interfaces the commu­nications board to the main PCB. Upon initial start-up, the Profibus communications board will be recognized by
the main PCB microprocessor.

2. Secure the purple Profibus cable with a cable

gland fittings and nut from the outside of the enclo­sure to ensure a proper seal. Note that the cable
gland fittings (PN 23554-00 - Cable Gland Kit,
Quantity 5) does not require the securing nut inside
the enclosure to properly install the fitting. Simply
thread the fitting into the grounding plate inside the
enclosure and tighten.

Once the gland fitting is tightly screwed into the
enclosure and internal grounding plate, only the
external nut needs to be tightened to properly seal
the Profibus cable.

INSTALLATION AND WIRING

3.2 Wiring Directly To A Profibus Network

To connect a Profibus-configured Model 1056 to a Profibus network, the conventional method is to wire a stan-

dard purple Profibus cable directly to the Profibus board inside the instrument. The Profibus board is designed
to accommodate direct wiring of a Profibus cable to a removable 4-lead terminal block on the Profibus board.

1. Feed the purple Profibus cable through a cable gland fitting. Install the cable gland fitting into the enclosure

opening on the leftmost side of the enclosure nearest the front of the door hinge. See photo. Note that the
power cable should be installed in the leftmost side of the enclosure farthest from the front of the door hinge
– as shown in the photo below.

removable terminal block. A #0 Philips head screw
driver is required to open and close the terminal
posts on the terminal block. The lead positions are
labeled on the Profibus card (A and B) to assist in

wiring.
Note: that Profibus wiring is polarity-sensitive. The
Green color lead must be wired to lead position A.
The Red color lead must be wired to lead position B.

Caution: Make sure the Profibus cable is properly
prepared. Unshielded wire leads can lead to poor
signal integrity from the Profibus device to the Master

5. After wiring the Profibus cable to the terminal block,
slide the wired 4-lead terminal block onto the 4 pins
protruding from Profibus board on the left side.
Photo shows the 4-lead terminal block properly
wired to the Profibus board and installed onto the

MODEL 1056DP SECTION 4.0

PROGRAMMING PROFIBUS

5.1 COMMUNICATIONS ARCHITECTURE- OVERVIEW

The PROFIBUS-DP communications profile specifies the operating characteristics of a serial fieldbus intended
for the interconnection of distributed digital devices at the field level. To achieve this, PROFIBUS designates
these devices as either masters or slaves:

• Masters, or active stations, control the transmission of data around the bus. A master may transmit messages
freely although, sometimes, it may have to obtain network access rights (in the case of multi-master applications
using tokenpassing).

• Slaves, or passive stations, are distributed devices (I/O devices, valves, instrumentation transmitters, etc.)
that do not have bus access rights without authorization. Their operation is limited to acknowledging messages
received or transmitting messages at the request of a master device. In order to route data to its destination
address, or to tell the destination address how to handle the data received, a formal set of rules and conventions
for the exchange of data signals is required.

The International Standards Organization (ISO) uses an outline model referred to as the Open Systems
Interconnection (OSI) reference model. This reference model defines 7 levels used in the transfer of data. These
levels are referred to as layers. PROFIBUS-DP operates on the two lowest levels, layer 1 (physical connections)
and layer 2 (data links). Layers 3 to 7 are unused in this profile.

5.2 DATA TRANSMISSION

PROFIBUS-DP is designed for efficient communication between programmable logic controllers (PLCs), industrial
PCs (IPCs), etc., and distributed peripheral devices such as I/O devices, drives, valves, and measurement sen­sors, etc. Most data exchanges are carried out in a cyclic fashion. The communication functions required are spec­ified by the basic PROFIBUS-DP communications profile, in accordance with the European harmonized standard,
EN 50170.

5.3 DEVICE DATABASE FILE (GSD FILE)

PROFIBUS devices may be defined in terms of their performance and their available functions, e.g. the number
of I/O signals and diagnostic messages, and their bus settings, such as transmission speeds or time monitoring.
These settings will vary with the equipment type and manufacturer but they are usually defined in the manufac­turer's documentation.

To simplify PROFIBUS configuration or even make it transparent to the user, this data is collected together into a
single computer file, sometimes referred to as a device data base file or, more often, a GSD file.

GSD files provide a clear and complete description of a device's properties. The Model 1056 device has its own
GSD file.

Model 1056 GSD files may be downloaded free from the GSD library on the web server at:
