STEP 7-Micro/WIN (VERSION 2.0)
Copyright (c) Siemens Energy & Automation Inc., 1997

--------------- INSTALLATION ---------------

Close all applications including the MS-Office Toolbar before installing STEP 7-Micro/WIN.  Other applications that use the same set of system files must be closed in order for STEP 7-Micro/WIN to install properly.

System Requirements:

*  You must have at least 8MB of RAM in order to run STEP 7-Micro/WIN.
*  486/33MHz computer (recommended), 386/25MHz (minimum)
*  PC/PPI communication cable to connect to your S7-200 CPU
*  MS-Mouse (recommended)
*  Windows 3.1 & 3.11, Windows95, or Windows NT3.51 or later
*  35 Mbytes of free hard disk space (recommended)

Installation Instructions:

(Windows95, WindowsNT 4.0 or later)
1. Insert STEP 7-Micro/WIN Diskette 1 in Drive A or B.
2. Click on the Start button and select Run.
3. Type A:\Setup or B:\setup (according to the drive you selected in Step 1).
4. Click on the OK button.
5. To complete the installation follow the instructions displayed.

(Windows 3.1, Windows 3.11, WindowsNT 3.51)
1. Insert STEP 7-Micro/WIN Diskette 1 in Drive A or B.
2. Select File->Run from the Program Manager.
3. Type A:\Setup or B:\setup (according to the drive you selected in Step 1).
4. Click on the OK button.
5. To complete the installation follow the instructions displayed.

--------------- KNOWN PROBLEMS & REMEDIES --------------

1. If you open a STEP-7 Micro/DOS project (*.VPU), do not use the same filename for the STEP 7-Micro/WIN project.  STEP 7-Micro/WIN will overwrite the STEP 7-Micro/DOS comment file.

2. If you experience problems printing with an HP 660Cse Color printer, change the printer driver to the basic HP Deskjet printer driver to correct the problem.  If you are experiencing problems with other printers, try using a different printer driver.

3. If you are using STEP 7-Micro/WIN on a Siemens PG 740 programming device and experience communications problems with the CPU, newer communication drivers are required. These newer drivers are provided on STEP 7-Micro/WIN diskettes. To correct the problem, copy the newer drivers (COMM.DRV and SERIAL.386) from disk 4 into your Windows\System directory.

4. When running Windows 3.1 or 3.11, ensure that you are running in Enhanced mode for proper operation.

5. Previous versions of STEP 7-Micro/WIN would allow certain ladder constructs to be created that are no longer supported in the ladder view. If you see "Illegal" for the network number, don't worry your code it still there, but you have encountered a situation where the statement list code can not be converted to its ladder equivalent.  You must go to the Statement List View and re-work your code before the network can be represented in ladder.

--------------- NATIONAL LANGUAGES ---------------

STEP 7-Micro/WIN uses several Microsoft Common Dialogs.  The text in these dialogs will appear in the national language of the operating system.

--------------- MPI COMMUNICATIONS ---------------

Setting STEP 7-Micro/WIN Network Addresses:

As a general rule, use the lowest available addresses for masters and the higher addresses for slaves. It is preferable, but not required, to use consecutive addresses for the masters on a network. For example, a network with STEP 7-Micro/WIN, a TD 200, an OP15, and some number of S7-200s could use address 0 for STEP 7-Micro/WIN, 1 for a TD 200, and 2 for an OP15. The S7-200s could then be addressed as 3, 4, and 5, or you could leave these numbers free for additional masters and start the numbering of the S7-200s at 16.

TD 200/MPI

Currently, there exists a problem when downloading or uploading a large program with the CPU 215 or CPU 216 while the TD 200 is polling the CPU.  The current time-out error on the TD 200 is no longer appropriate for these newer CPU models.  A work around is to temporarily disconnect the TD 200 from the network, download or upload the program, and then reconnect  the TD 200 to the network.

Setting up the MPI Card with STEP 7-Micro/WIN:

In order to communicate using the MPI card, the STEP 7-Micro/WIN MPI driver requires that the memory space that is used by the card be reserved (excluded) by the system.  This prevents the memory manager from allocating this area of memory to another application.  SIMATIC STEP 7 does not require this memory to be excluded, but should operate properly with the memory either included or excluded.

The memory space used by the MPI card is selected by using the switches on the card.  The default switch positions on the MPI card are Switch 1 = off, Switch 2 = on, and Switch 3 = off.  This corresponds to a default address space of 0xDC000-0xDC407 on a PC, which is the recommended address space.  On a PG, the default is 0xCC000-0xCC407.  The procedure for excluding this memory depends upon the memory manager in use.  Three cases are given as examples for setting up the MPI card parameters. Be sure to back up your Config.sys file before making any changes.

Case 1:  MPI Card on a PG or PC Running Windows 3.1, Windows 3.11, or Windows95 (without SIMATIC STEP 7 installed on the system).

1. Look for a similar line of code below in the CONFIG.SYS that loads the memory manager. 
   For example, DEVICE=EMM386.EXE X=E000-EFFF
2. Add the new parameter X=DC00-DCFF and save the file.
3. The end result should look as follows: DEVICE=EMM386.EXE  X=DC00-DCFF  X=E000-EFFF

Please note that this configuration example assumes that the MPI card is at address 0xDC00 which is the default for the PC ISA card. If the settings are different, then the address range to be excluded should be changed to match the card.

Case 2:  MPI Card on a PG or PC Running Windows 3.1, Windows 3.11, and SIMATIC STEP 7, Version 1.0 installed on the system.

1. Look for a similar line of code below in the CONFIG.SYS that loads the memory manager. 
   For example, DEVICE=EMM386. NOEMS  EXE  X=E000-EFFF
2. Add the new parameter X=DC00-DCFF and save the file.
3. The end result should look as follows: DEVICE=EMM386.EXE  NOEMS  X=DC00-DCFF  X=E000-EFFF

Please note that this configuration example assumes that the MPI card is at address 0xDC00 which is the default for the PC ISA card. If the settings are different, then the address range to be excluded should be changed to match the card.

Case 3:  MPI Card on a PG or PC Running Windows95, and SIMATIC STEP 7, Version 2.1 installed on the system.

1. Look for a similar line of code in the CONFIG.SYS that loads the memory manager.  For 
   example, DEVICE=EMM386.EXE   X=A000-BFFF  I=C000-CCFF  I=CD00-DFFF  X=E000-EFFF  
   FRAME=D000
2. Change the I=C000-CCFF  to  X=C000-CCFF and save the file.
3. The end result should look as follows: DEVICE=EMM386.EXE X=A000-BFFF  X=C000-CCFF 
   I=CD00-DFFF  X=E000-EFFF  FRAME=D000

Please note that this configuration example assumes that the MPI card is at address 0xCC00 which is the default for a PG.  If the settings are different, then the address range to be excluded should be changed to match the card.


STEP 7-Micro/WIN can now be operated using one of the serial ports or the MPI card.

Note:  Address ranges given above are segment ranges used by the EMS driver program (memory manager).  Approximately 4K bytes of reserved space are allotted for the MPI card.
