You are provided with information on how to employ this communica-tions processor to communicate via Industrial Ethernet (IE).  Prerequisites A prerequisite for understanding how the CP 243-1 works is familiarity with this manual and the "SIMATIC S7-200 Automation System" (MLFB: 6ES7298-8FA21-8AH0) manual. You must also have a basic understanding of the TCP/IP protocol. Target group This manual is directed toward engineers, programmers, commissioning engineers and maintenance technicians with a general knowledge of automation and com-munication systems and human machine interface systems. Sample program This manual contains a sample program that provides you with information and as-sistance in programming the CP 243-1. This sample program was created with STEP 7-Micro/WIN 32 (MLFB: 6ES7 810-2BC02-OYXO) and can be run on an S7-200 CPU, type 224. To run this sample program on another S7-200 CPU, you may have to adjust the configuration of the sample program. Product Information Address label: MAC address The CP 243-1 is delivered with a fixed MAC address. The MAC address is affixed to the underside of the upper door of the device. MLFB number, scope of delivery Product name  MLFB  Scope of delivery CP 243-1 6GK7 243-1EX00-0XE0 CP, documentation on CD-ROM  1  Introduction Definition and application The CP 243-1 is a communications processor designed for operation in an S7-200 automation system. It is used for connecting an S7-200 system to Industrial Ethernet (IE). The CP 243-1 also facilitates communication via Ethernet for the S7 product family. As a result, S7-200 can be remotely configured, programmed, and diagnosed via Ethernet using STEP 7 Micro/WIN 32. Moreover, an S7-200 can communicate with another S7-200, S7-300, or S7-400 controller via Ethernet. It can also communicate with an OPC server. In the open SIMATIC NET communications system, Industrial Ethernet is the net-work for both the coordination level and the cell level. Technically, the Industrial Ethernet is an electrical network built on the basis of a shielded coaxial cable, twisted pair cabling, or an optical network using a fiber optic cable. Industrial Ethernet is defined by the international standard IEEE 802.3. Continuous communication in the industry sector Industrial Ethernet is an integral part of the SIMATIC NET concept, which together with PROFIBUS and the AS Interface ensures continuous networking of the coor-dination, cell and field levels.  Compatibility The CP 243-1 (6GK7 243-1EX00-0XE0) described here can be used for S7 com-munication. The CP 243-1 can be connected to various types of S7-200 CPUs (222, 224, 226 and 226XM): •  CPU 222 Rel. 1.10 or higher  (Rel. 1.20 or higher is recommended) •  CPU 224 Rel. 1.10 or higher  (Rel. 1.20 or higher is recommended) •  CPU 226 Rel. 1.00 or higher  (Rel. 1.20 or higher is recommended) •  CPU 226XM Rel. 1.00 or higher  (Rel. 1.20 or higher is recommended) A maximum of 2 expansion modules can be mounted on the CPU 222. In contrast, up to 7 expansion modules can be connected to the 224, 226 and 226XM CPUs. A detailed compatibility specification you will find in Appendix D. Attention Only one CP 243-1 should be connected per S7-200 CPU. It cannot be guaranteed that the S7-200 system will operate properly if additional CP 243-1 are connected. The CP 243-1 software is compatible with the following standards: •  S7 XPUT/XGET and S7 READ/WRITE •  S7-200 I/O bus specifications The position in an S7-200 system in which a CP 243-1 can be operated depends on the firmware version of the S7-200 CPU, see also chapter 3 (Installation) Planning  The CP 243-1 is configured using STEP 7 Micro/WIN 32, version 3.2.1. or higher. The CP 243-1 is always delivered with a fixed MAC address. The IP address and the subnet mask either must be configured or  they must be retrieved from a BOOTP server via the BOOTP protocol. For the purpose of monitoring connections (Keep Alive), a time can be configured for all TCP transport connections with active and passive partners. A total of 8 connections to other controllers or OPC servers can be maintained at any one time.  Programming To program the communication in the user program, use the "Ethernet Wizard" in STEP 7 Micro/WIN 32; see Chapters 4 and 5. Configuration The CP 243-1 firmware is programmed into the Flash memory during production and is permanently stored there. System conditions or dynamic variable contents that are generated during  CP 243-1 operation do not survive a loss of power. The CP 243-1 is configured with STEP 7 Micro/WIN 32, version 3.2.1 or higher, and the configuration is stored in the V-Memory of the S7-200 CPU as non-volatile data. Upon booting, the CP 243-1 reads the configuration out of the CPU and ini-tializes itself accordingly.   2  Features and Functions  2.1  Overview The CP 243-1 features the following functions: •  S7-200自动化系统英文文献和中文翻译:http://www.youerw.com/fanyi/lunwen_52483.html
