Preface:
--------

  We would like to thank you very much for purchasing both
  the Fieldbus unit[CA5-PFSALL/EX-01] and the GP-Pro EX 
  software.
  This readme file explains how to use/configure Packet Transfer
   option in PROFIBUS Network for AGP.

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

On the GP-Pro EX CD, folder "FIELDBUS" ( e.g.
E:\FIELDBUS\ ) the following files are contained:

 1. README.TXT	 => This File

 2. PF_AGP_P.ZIP => A software for decompressing file.
		    Step 7 Library containing "Packet Transfer"
		    interpreter program for Profibus-DP.
		    (For versions before STEP7 V5.3.)

 3. PF_AGP_P_V53.ZIP
		 => A software for decompressing file.
		    Step 7 Library containing "Packet Transfer"
		    interpreter program for Profibus-DP.
		    (For STEP7 V5.3 or later.)

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

 5. PFE_08DF.GSD => CA5-PFSALL/EX-01 Profibus DP Slave GSD File.

 6. PFE_08DF.BMP => CA5-PFSALL/EX-01 Profibus DP Slave Bitmap Icon File.


NOTE: The files contained within the Fieldbus directory on the
GP-Pro EX 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. GP-Pro EX Configuration:
----------------------------------------

    Please refer to GP-Pro EX PROFIBUS DP Slave 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
   GP-Pro EX 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 GP-Pro EX 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 "Pro-face CA5-PFSALL/EX-01" 
   onto your Profibus-DP network.
6. Next expand the "Pro-face CA5-PFSALL/EX-01" folder and drag the 
    modules based on your input and outsize. Then set the DP Slave 
    number. This Slave number should match with the GP-Pro EX project 
    slave number.
7. If you use Packet Transfer, please make sure the Packet Transfer Module
    is the last module in your configuration.
8. Depending on the communication mode choosen, the following
   settings should be observed,
9. 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 AGPs, each AGP requires a separate FB99 call and 
  separate Data Blocks, e.g. 2 AGPs:

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

 CALL  FB99,DB100	// AGP #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. But the current 
version can be used for GP2000 PROFIBUS DP Slave.
