The CPU modules in Figure 3-4 could be either slave or master devices.Microsoft, Windows, Windows 95, and Windows NT are registered trademarks of Microsoft Corporation.For Internet information about Siemens products and services, technical support, or FAQs (frequently asked questions) and application tips, use this Internet address.The compact design, expandability, low cost, and powerful instruction set of the S7-200 Micro PLC make a perfect solution for controlling small applications.
In order to use a personal computer (PC), you must have one of the following sets of equipment: A PCPPI cable. S7-200 CPU Module The S7-200 CPU module combines a central processing unit (CPU), power supply, and discrete IO points into a compact, stand-alone device. As shown in Figure 1-6, the expansion module comes with a bus connector for connecting to the base unit. You can use the mounting holes to attach the modules to a panel, or you can use the built-in clips to mount the modules onto a standard (DIN) rail. An IO expansion cable is also available to add flexibility to your mounting configuration. Figure 2-3 shows the dimensions for this rail. Failure to disable all power to the S7-200 modules and related equipment during installation or removal procedures may result in death or serious personal injury, andor damage to equipment. Provide a single disconnect switch (1) that removes power from the CPU, all input circuits, and all output (load) circuits. Provide overcurrent devices to protect the CPU power supply (2), the output points (3), and the input points (4). The effectiveness of a given design depends on the application, and you must verify it for a particular use. Be sure all components are rated for use in the application. Use the following information as a guide for determining how much power (or current) the base unit can provide for your configuration. Make sure all applications are closed, including the Microsoft Office toolbar. Although the hardware modules are the same for either operating system, installation under Windows NT requires more knowledge of the hardware that you want to install. Siemens S7 200 Software Software On AYou can install the STEP 7-MicroWIN software on a personal computer (PC) that has a Windows 3.1x, Windows 95, or Windows NT operating system, or you can install it on a SIMATIC programming device (such as a PG 740). STEP 7-MicroWIN is designed to communicate with one S7-200 CPU at a time; however, you can access any CPU on the network.
