--------------- 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, 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 edit your code before the network can be represented in ladder.




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

STEP 7-Micro/WIN uses several Microsoft common dialog boxes.  The text in these dialogs will appear in the national language of the operating system, regardless of the language you have chosen for STEP 7-Micro/WIN.

------- MULTI-MASTER COMMUNICATIONS -----

Special Note:
     When using Multi-Master communications on networks with several masters (including TDs, OPs, etc.), the hardware takes several seconds to be initialized onto the PLC network. If communication is attempted before this initialization is complete, an error may occur. If such an error does occur, retrying the last request should correct it.


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:
     There exists a possible problem when downloading or uploading a program with the CPU 215 or CPU 216 when an older TD 200 (pre-v1.2) is polling the CPU. The current time-out error on the TD 200 is no longer appropriate for these newer CPU models. A workaround is to temporarily disconnect the TD 200 from the network, download or upload the program, and then reconnect the TD 200 to the network.


Master Mode Communications Error:

     STEP 7-Micro/WIN might report erroneous communications time-out errors when the PLC is in Master mode. For example, using STEP 7-Micro/WIN to put the CPU in STOP mode might return this error even though the CPU did in fact go to STOP mode.  


There may be a problem when using Multi-master communications with a PC/PPI cable on a 386 or 486 computer with Windows 95.  The Find function will work but no other communication function will work correctly.  The problem may be corrected by enabling the 16550 UART setting and adjusting the receiver FIFO level to the lowest setting for the COM port.  This is done with the Windows Device Manager.

------- PPI COMMUNICATIONS -------

Using PPI Multi-Master Configuration: 
     When Multi-Master is checked on the PPI Network tab and STEP 7-Micro/WIN is communicating through COM1 or COM2, if you start another application which uses the same COM port as STEP 7-Micro/WIN, neither application will operate correctly. If this occurs, close both applications, then restart only one.

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

Setting up the MPI Cards 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 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 address space on the MPI card is 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.  

     Example cases for setting up the MPI card parameters are given below. Be sure to back up your CONFIG.SYS file before making any changes.

  MPI Cards for STEP 7-Micro/WIN 16 using Windows 3.x, Windows 95, Windows NT
  ---------------------------------------------------------------------------

  - Case 1:  MPI Card on a PG or PC running Windows 3.x or Windows 95.

       1. In the CONFIG.SYS file, look for a line of code similar to the following that loads the memory manager: 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 95.

       1. In the CONFIG.SYS file, look for a line of code similar to the following that loads the memory manager: 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.


  MPI Cards for STEP 7-Micro/WIN 32 using Windows 95
  --------------------------------------------------

  - Case 1: CP5511, CP5611 
     These cards are Plug-and-Play; they are automatically detected and self-initializing.

  - Case 2: CP5411, MPI-ISA Card, MPI-ISA Card on Board
     These cards are installed from the communications setup. The address ranges and interrupt are detected by Windows 95 and set up automatically.


  MPI Cards for STEP 7-Micro/WIN 32 using Windows NT
  --------------------------------------------------

  - Case 1: CP5511, CP5611
     These cards are Plug-and-Play; they are automatically detected and self-initializing.

  - Case 2: CP5411, MPI-ISA Card, MPI-ISA Card on Board
     These cards are installed from the communications setup. It is necessary to specify the resources (addresses space and interrupt) used by the card from the communications setup.
