Introduction

The VersaPoint product family is a modular automation system. With
VersaPoint modules you can easily add one module to the next and build
functional units that meet your automation requirements exactly.

A set of interconnected VersaPoint I/O modules can be selected to suit the
application, and connected as a slave on a Profibus-DP network. The
interface between the network and the modules is a VersaPoint Profibus-DP
Network Interface Unit (NIU).

The NIU is located to the left of the other modules. Together, the NIU and
the modules selected for the application function as an I/O Station. The I/O
Station can include up to 63 I/O modules.

Within the VersaPoint station the bus connection, power supply, and power
distribution for the devices connected to the bus terminal are realized by
connecting modules together on the DIN rail.

Sensors and actuators are easily wired to the VersaPoint I/O modules via
spring-clamp terminals on the modules' removable connectors. These
connectors can be keyed so that they cannot be mixed up. If a module must
be exchanged the wiring does not need to be removed. Just remove the
connector from the terminal.

Features

Advantages

Characteristic VersaPoint features are:

– Modules can be easily installed/interconnected without tools.

– Automatic creation of isolated groups, current, data, and safety circuits

– Open, flexible, and modular structure

– Modules of varying point counts can be combined to create a

VersaPoint station that optimizes unit space while minimizing unit cost.

VersaPoint design offers the following advantages:

– Reduced control cabinet space.

– The amount of costly parallel wiring is reduced. Within a station, voltage

and data routing can be carried out without additional wiring.

– The modular structure makes it possible to assemble standard function

blocks in advance. Different parts of the system can be operated
independently of one another. This means that pretests can be carried
out when the system is set up and that the whole system can be
adapted and expanded.

I/O Station Capacity

– Up to 63 devices can be connected to an NIU (Depending on power

consumption. See chapter 5).

– The sum of all input and output data can be up to 184 bytes per station.

The Profibus System

Profibus is a serial bus system for data transmission between control systems and
distributed input and output modules, to which sensors and actuators are
connected.

Profibus has a star tree structure. In the Profibus topology the single bus devices
can be differentiated by means of their addressing. The communication profiles
determine how the devices transmit their data via the bus.

Profibus DP is normally a single master system. It is designed for easy
transmission of input and output data and specifically designed for communication
between automation systems and the distributed I/O devices.

Typical Profibus-DP VersaPoint I/O Station

A set of interconnected VersaPoint I/O modules can be selected to suit the
application, and connected as a slave on a Profibus-DP network. The interface
between the network and the modules is a VersaPoint Profibus-DP Network
Interface Unit (NIU) module.

The intelligent wiring method used in the VersaPoint modules allows I/O stations
to be constructed easily and quickly. Normally, it is only necessary for the power
supply units integrated in the Profibus NIU to be supplied with 24VDC on the input
side. They generate the operating voltage required for the NIU itself and for the
connected VersaPoint I/O modules.

Items Used with the NIU

The Profibus NIU comes with an end plate, the latest GSD file, and one set of end
clamps.

The end plate is installed at the end of the VersaPoint station, after the last
module. It protects the station from electrostatic discharge and the user from
dangerous voltage.

The power connector is ordered separately. See the ordering information below.

Line Terminal Resistors

Since Profibus is a serial bus system in a star-tree structure, the individual
branches must be terminated with a terminal resistor. The NIU does not have an
integrated resistor of this type. Many Profibus connectors are available with an

integrated, switchable resistor. Please contact your GE Intelligent Platforms

NIU Power

The NIU acts as a power terminal, supplying the logic and module power for some
or all of the of the I/O modules in the station, as well as the sensors and actuators.
Some stations will also use additional power/segment terminals, depending on the
needs of the application. See chapter 5 for additional details.

DIP Switches on the NIU

The 10-position DIP switch on the NIU module is used to set the Profibus address.
In addition, switch 8 can be used to select the operating mode of Profibus NIU
IC220PBI002. For model PBI001, the same switch specifies the error response of
the NIU.

For Module IC220PBI002: Sets the operating mode. With this switch in
the Off position (the default), this module can directly replace module
version IC220PBI001.

With this switch in the On position, this module operates in DP/V1 mode.

For Module IC220PBI001: Behavior if a data error occurs in the station
(local bus error):

ON = data transmission is stopped after a number of attempts.
OFF = the station constantly attempts to start data transmission.

If DIP switch 8 is in the ON position, a POWER DOWN/POWER UP must
be executed on the NIU so that it will restart. There is no automatic
restart after the error has been removed.

Reserved, both switches must be in the OFF position.

LEDS on the NIU

The diagnostic LEDs on the NIU indicate the type and location of errors.

The module is functioning correctly if all of the green LEDs are on.

Once errors have been removed, the indicators immediately display the current
status.

NIU LED Color Meaning

UM Green On = supply voltage in the main circuit for the NIU,

communications power and interfaces present. Off = main
circuit supply not present.

US Green On = 24 V segment circuit supply present

BF Red On = No communication on Profibus. Off = no error.

Flashing = PLC stopped, outputs default to safe values.

FS Red Defines the function of the FN LED:

FS ON: FN indicates the type of error.
FS OFF: FN indicates the error number

FN Red Off = no error. If flashing, the number of pulses indicates

the type of error or the error number, depending on
whether FS is on or not

Diagnostics

The NIU provides the following standard Profibus and device-related diagnostics.

Error Type Meaning

1 Parameter error on Profibus (SET_PRM telegram)

2 Configuration error on Profibus (CHK_CFG telegram)

3 Configuration error in the station

4 Error within the station

5 Module error

6 Parameter error on local bus

7 EEPROM error

DPV1 Communications for Profibus NIU IC220PBI002

If the DP/V1 communications features of Profibus NIU IC220PBI002 are enabled
by configuration and if DIP switch 8 on the module is set to the On position, the
NIU supports enhanced DP/V1 communications with the master.

DP/V1 expands the cyclic data exchange function according to IEC 61158 to
include acyclic services. This makes it easy to operate even complex devices.

The Profibus NIU prepares the data records, which are sent via DP/V1 from the
master, and provides them to the specified modules in the I/O Station. The NIU
converts data from the modules into DP/V1 telegrams for the Profibus master.

Masters with DP/V1 ability include the PACSystems RX3i Profibus Master Module,
IC695PBM300, and the Series 90-30 CPU model IC693CPU366. Both of these
masters can use three types of COMMREQ (Communications Request) functions
in the application program to communicate with the Profibus NIU:

DPV1 Read Request Performs a DPV1 read request from a slave device

(such as the Profibus NIU).

DPV1 Write Request Performs a DPV1 write request to a slave device.

DPV1 Alarm Request Acknowledges a DPV1 alarm request.

Modules in a VersaPoint Station

A VersaPoint I/O Station begins with a Network Interface Unit (NIU). The
NIU module is the first module on the DIN rail, at the left end of the I/O
Station. It is shown here with the required grounding to the DIN rail. See
chapter 2 for more information about the Profibus-DP Network Interface
Unit. The NIU performs all the data-handling and communications functions
for the I/O Station.

The rest of the station is made up of a group of I/O modules that can be
selected to exactly fit the needs of the application.
