Profibus Option Card for PG Operator
Interface Terminals
Specification Sheet
General Description
The PG proprietary expansion slot provides a high speed, parallel architecture that extends the functionality and flexibility of the PG series
HMI. This approach allows the PG series to evolve concurrently with the latest advances in communications and standards, without sacrificing performance. This high bandwidth channel has significantly greater throughput when compared to the traditional (external) serial gateway approach.
The PGX-PBUS option card adds Profibus DP connectivity to any PG series HMI. This allows a high speed exchange of blocks of data, at data rates up to 12 MBaud, between the hosting PG and a Master PLC on a
Profibus network. The DP suffix refers to “Decentralized Periphery”, which is used to describe distributed I/O devices connected via a fast serial data link with a central controller.
The card is easily installed by removing the rear cover of your PG operator interface, attaching the card using three screws and connecting a single cable.

Installing the PGX-PBUS Option Card
Mounting Instructions
Each PGX-PBUS option card comes with three screws for attaching the option card to the inside of the PG operator interface’s rear cover.
To install the option card remove all power and I/O communications cables from the unit. The PG operator interface literature contains instructions for removing the rear cover, refer to the “Battery & Time
Keeping” section.
Using the three screws provided connect the option card to the rear cover as shown in the figure below.
Connect the cable from the option card to CN11 on the main board of the PG operator interface as shown in the figure below. Be sure both ends of the cables are firmly seated into their appropriate connector housing.
Carefully replace the rear cover by reversing the instructions for removing the rear cover.
CAUTION - THE OPTION AND MAIN CIRCUIT BOARDS CONTAIN
STATIC SENSITIVE COMPONENTS. BEFORE HANDLING THE CARDS,
DISCHARGE STATIC CHARGES FROM YOUR BODY BY TOUCHING A
GROUNDED BARE METAL OBJECT. IDEALLY, HANDLE THE CARDS AT
A STATIC CONTROLLED CLEAN WORKSTATION. ALSO, HANDLE THE CARDS
BY THE EDGES ONLY. DIRT, OIL, OR OTHER CONTAMINANTS THAT MAY
CONTACT THE CARDS CAN ADVERSELY AFFECT CIRCUIT OPERATION.
WARNING - DEPENDING UPON THE PG OPERATOR INTERFACE, HIGH
VOLTAGE MAY BE PRESENT INSIDE THE OPERATOR INTERFACE. BE
SURE TO REMOVE ALL POWER BEFORE REMOVING THE REAR COVER
OF THE OPERATOR INTERFACE. EMISSIONS EN 55011 CLASS A.
The Option Card Label
Place the option card label on your rear cover in the space indicated by the dashed lines and labeled “COMMS EXPANSION
MODULE.”

Communicating with the PGX-DNET Option Card
Configuring a PGX-PBUS Option Card
The PGX-PBUS is configured using GUIcon software. GUIcon is available as a free download from www.eurotherm.com. Updates to
GUIcon for new features and drivers are posted on the website as they become available. By configuring the PGX-PBUS using the latest version of GUIcon, you are assured that your unit has the most up-to-date feature set. GUIcon software can configure the
PGX-PBUS card through the RS232 PGM port, USB port, Ethernet port, or CompactFlash socket on your PG operator interface.
Additional information can be found in your PG hardware bulletin and the GUIcon user manual.
Configuring the Driver
To select a driver, click on the left hand pane of the
Communications window and highlight the Profibus Interface icon.
In the right hand pane, click the Driver Selection Edit button to show the Driver Selection dialog and select the Profibus DP driver from the list.
•
The Station Address of the Profibus node is the only property that needs to be configured. This should be a unique address on the Profibus Network in the range 1..125.
To enable the option card, click on the left hand pane of the
Communications window and highlight the PG icon. In the right pane, click the Option Card Selection Edit button to show the selection dialog and select the Profibus Option Card from the list.
The Profibus Option Card will then appear in the left hand pane, installed in the tree of available ports.
PGX-DNET Port Pin Outs
Configuring the Data Tags
A Profibus master exchanges data with slaves as separate input and output blocks. Data transfer direction is described with respect to the Profibus Network such that input data is transferred to the network, or written by the PG and output data is transferred from the network or read by the PG. This is important when it comes to configuring the data access for each tag mapped to a Profibus data block.

WD
Data
Mapping Tags to a Data Block
Profibus data blocks have no concept or knowledge of data type or structure – they are described by a size in bytes. GUIcon’s Tag based approach to data allows for data of mixed type, bytes, 16-bit words and 32-bit words to be mapped into a single data block.
To map a data tag to a Profibus Data block, click in the left hand pane of the Data Tags window, highlight the required Data Tag icon. In the right hand pane click the Data Mapping button and select the Profibus device to show the Select Address for Profibus
DP dialog.
•
The Block Type defines whether the tag will be read from
(Output Block) or written to (Input Block) the Profibus network
•
The Data Offset is the byte address of the Data Tag within the
Data Block
•
The Data Type is the actual size in bytes of the data that will be mapped into the Data Block.
Configuring Data Access
As described above, Data Tags are mapped to either an Input
Block and are Write only, or an Output Block and are Read Only.
The Access must be selected to reflect this.
