Preface:
--------

  We would like to thank you very much for purchasing both
  the Fieldbus unit[XBTZPDP] and the Vijeo Designer 
  software.
  This readme file explains how to use/configure Packet Transfer
   option in PROFIBUS Network for XBT GT.

1. "FIELDBUS" Folder Contents:
------------------------------

In the folder "FIELDBUS" on Disc 2 of the Vijeo Designer Installation CD ( e.g.
E:\TOOLS\FIELDBUS\ ) the following files are contained:

 1. README.TXT	   => This File

 2. TE_XBT_Lib.ZIP => A software for decompressing file.
		    Step 7 Library containing "Packet Transfer"
		    interpreter program for Profibus-DP.

 3. TE_XBT_P.ZIP   => A software for decompressing file.
 		    Step 7 Example Project containing "Packet
		    Transfer" interpreter program for Profibus
		    -DP and example configuration.

 4. TELE08DF.GSD   => XBTZPDP Profibus DP Slave GSD File.

 5. TELE08DF.BMP   => XBTZPDP Profibus DP Slave Bitmap Icon File.


NOTE: The files contained within the Fieldbus directory on the
Vijeo Designer CD are NOT copied to the hard-disk
during installation. The user must copy these files to a
location on their computer where they can use them.

2. Vijeo Designer Configuration:
----------------------------------------

    Please refer to Vijeo Designer Driver manual for 
    more detailed information.

3. Siemens Step 7 Configuration:
-------------------------------------------

   Please refer to the SIEMENS SIMATIC STEP 7 Help and manual for detailed 
   information.

 Hardware Configuration

1. Ensure that the relevant GSD electronic description file has
   been copied to the correct directory of your computer.
   This file is contained in the Fieldbus directory on the
   Vijeo Designer installation disk.
   Note: Depending on the version of Step 7 you are using the
   directory names/structure can vary, you should copy this file to
   the directory under the Step 7 directory where other GSD files
   are stored.
2. Open Step 7, start a new project and enter the hardware
   configuration for your S7 3/400 station. Alternatively you can
   base your project on the example project contained in the
   Fieldbus directory on the Vijeo Designer installation disk.
3. Click "Options Update DDB Files" to inform the Step7 software
   of the Profibus-DP module parameters.
4. Enter the relevant hardware for your S7 rack.
5. Open the hardware catalogue and from "PROFIBUS DP->Additional
   Field Devices->MMI, drag the folder "XBTZPDP" 
   onto your Profibus-DP network.
6. Next expand the "XBTZPDP" folder and drag the 
    modules based on your input and outsize. Then set the DP Slave 
    number. This Slave number should match with the Vijeo Designer project 
    slave number.
7. If you use Packet Transfer, please make sure the Packet Transfer Module
    is the last module in your configuration.
7. Depending on the communication mode choosen, the following
   settings should be observed,
8. Set up the Input and Output addresses of the Profibus-DP
    interface unit. The user should make note of both the input
    start address and output start address, as they will be needed
    later to correctly perform data transfer

PLC Program/Software Configuration for PACKET Transfer:

   For Packet transfer the user will have to incorporate and
   configure correctly the Interpreter program. On this CD the
   Interpreter program is provided in both a skeleton project
   format and a Step 7 library format. The program consists of
   a single function block (FB99). To use this function you
   should use the following function call:

 CALL  FB99,DB99
       IP_ADDR    :=***
       OP_ADDR    :=***
      ERR_BYTE    :=MB***
      TEMP_OUT    :=MB***
      GP_STATUS   :=MB***	

  The FB99 uses a Data Block ( DB ) to save data used by the 
  interpreter program. This requires 40 Bytes of PLC memory. Do not 
  use this memory area for anything else. By default DB99 will be 
  chosen and created automatically by STEP 7 software. It is also 
  possible to use other DBs just by editing the number. Also when 
  using multiple XBT GTs, each XBT GT requires a separate FB99 call 
  and separate Data Blocks, e.g. 2 XBT GTs:

 CALL  FB99,DB99	// XBT GT #1
       IP_ADDR    :=***
       OP_ADDR    :=***
      ERR_BYTE    :=MB***
      TEMP_OUT    :=MB***
      GP_STATUS   :=MB***	

 CALL  FB99,DB100	// XBT GT #2
       IP_ADDR    :=***
       OP_ADDR    :=***
      ERR_BYTE    :=MB***
      TEMP_OUT    :=MB***
      GP_STATUS   :=MB***	

NOTE: The current version of the Interpreter program (V4.01) 
The interface for earlier versions of the interpreter program
(FB99 Call) may have had a different interface.
