S7-PLCSIM V 5.3 + SP1

S7-PLCSIM V5.3 + SP1 offers the following new features with this release:

1. Support of F-System peripheral I/O variables with color indication in view objects
2. Support of CPU 317-T hardware configurations with limited support of instructions
3. Support of hardware configurations with CiR (Configuration in RUN) objects
4. Ability to support STEP 7 projects containing configurations with more than one PROFIBUS line In addition, the data formats String and DT (Date and Time) are no longer available in view objects for peripheral I/O variables.

To be able to work with STEP 7 Professional in MS Windows 2000/2003/XP, you must have logged on at least as the user (not as a guest). You must possess administrator's rights for installing the STEP 7 software and also for setting up modules using the "Setting the PG/PC Interface" application. You need to possess administrator's rights to use S7 GRAPH. When using optional packages please observe the rights required by the respective optional packages.

If projects are saved on NTFS drives, the users must be granted full access here. This also applies to the folders with the HSP updates (default: C:/HWUPDATES). Access within S7PROJ is automatically granted to all users.

Switching between Real and Simulated CPUs

You can switch simulation on or off from the SIMATIC Manager or from STEP 7 Lite. To avoid confusion between real and simulated CPUs when using STEP 7 tools, you can only be in one mode or the other. You can think of this as switching from the "real" world to the "simulated" world. This switch is carried out at the MPI network communication level, so the real MPI network is effectively replaced with a virtual network on which only one simulated CPU is visible (in the Accessible Nodes window, for example). Conversely, when real CPUs are visible, the simulated CPU cannot be seen. STEP 7 or STEP 7 Lite will ask you to close any connections to one type of CPU before you are allowed to switch to the other type. For more information, see the S7-PLCSIM online help or electronic manual.

To switch simulation on or off from the SIMATIC Manager, use one of these methods:

1. Select the menu command Options > Simulate Modules
2. Click the toolbar button for S7-PLCSIM

What You Can Expect to Do with S7-PLCSIM

S7-PLCSIM allows you to load and debug an S7 program without a PLC, using the tools in the STEP 7 Standard software package and the S7-PLCSIM interface. It is primarily useful for debugging logic. Timing differs significantly from real CPUs, so some hardware testing is still recommended for timing concerns. Inputs and outputs can be easily monitored and changed from the visual interface. This product allows you to debug one CPU at a time.

Not all features of S7 CPUs are supported, so some advanced features of special products may produce error messages when run with S7-PLCSIM. For a complete description of the differences, see the S7-PLCSIM online help or the electronic manual.
