  • Page 11: Application And Properties

    As a result, an S7-200 can be configured, programmed and diagnosed even at a distance using STEP 7 Micro/WIN 32 via Ethernet. Using a CP 243-1 also means that an S7-200 can communicate with another S7-200, an S7-300 or S7-400 controller via Ethernet.
  • Page 12 S7-200/300/400 in the appendix Access from and to the S7-200 (Page 125). NOTICE Only one CP 243-1 may be connected to an S7-200 CPU. If additional CP 243-1 communications processors are connected, the S7-200 system may not function correctly. CP 243-1...

  • Page 14 CP 243-1 starts up. If the watchdog monitoring is triggered, the CP 243-1 is automatically reset. This restarts the CP 243-1. During this time, the CP 243-1 reports a parity error to the S7-200 CPU. Handling such an error is described in the documentation of STEP 7 Micro/WIN 32.

  • Page 15: S7 Communication Via Industrial Ethernet

    ● The CP 243-1 has a valid IP address. This address may be permanently specified in the configuration or obtained from a BOOTP/DHCP server. At any one time, only one STEP 7 Micro/WIN 32 can communicate via a CP 243-1 with the S7-200 CPU. The Ethernet interface must be used when configuring the IT services.

  • Page 16: Communications Partners

    If you require communication with an OPC server, remember that the CP 243-1 does not support automatic querying of the objects on the S7-200 (for example DBxx etc.). A CP 243-1 can only communicate with an OPC server if this server supports the two S7 services READ and WRITE.
  • Page 17 Figure 1-1 Communications partners A CPU 22x with a CP 243-1 can communicate both with other S7-200, S7-300 and S7-400 systems and with an OPC server. A maximum of 8 connections are possible in addition to a STEP 7 Micro/WIN connection.
  • Page 18 CP 243-1 can be used both as client and as server. Communication between a CP 243-1 and an OPC server running on a PC/PG is based on the READ and WRITE S7 services. In this case, the CP 243-1 always functions as the server.

  • Page 19: It Communication

    When an S7-300 or S7-400 is acting as the server for a client running on an S7-200 system, the CP 243-1 expects that this server will always have a passive role. This means that, the S7-300 or S7-400 system is not allowed to send S7 requests to the S7-200 system.

  • Page 20: Types Of Communication

    2. Communication with an FTP client located on a remote system. 3. Communication with an FTP server. Such a server is typically located on a remote system. A link to the FTP server running on the CP 243-1 of the local S7-200 system is also possible.
  • Page 21 STEP 7 Micro/WIN 32. Note To allow e-mails to be sent by the CP 243-1, make sure that it can access a functioning e- mail server. One of the ways in which you can test whether or not a e-mail server is accessible is to use HTML page sendmail.htm, which ships with the CP 243-1 (see chapter HTTP server...
  • Page 22 Conversion procedures such as MIME or UUENCODE are not supported. It is also not possible to add attachments such as files to e-mails. The e-mail function of the CP 243-1 can always be enabled or disabled in the configuration. Communications partners In addition to conventional PCs, it is possible in principle to specify any terminal with e-mail capability as the e-mail recipient (for example cell phones or FAX machines).

  • Page 23: Ftp Server

    S7-200 CPU. Only one such value can be transferred per S7 cycle from the S7- 200 CPU to the CP 243-1. This means that the time needed to set up an e-mail depends on the amount of data to be inserted, the cycle time of the S7-200 CPU and the load on the S7 bus.
  • Page 24 FTP client. If the FTP server on the CP 243-1 is connected to an FTP client and a second FTP client wants to establish a connection to the FTP server, the server checks whether or not there was FTP-based communication between it and the first FTP client during the last 60 seconds.

  • Page 25: Ftp Client

    How it works The FTP client of the CP 243-1 can be used to transfer data from an S7-200 system to the file system of an FTP server, or the contents of a file can be copied to the DB of the local S7- 200 system.
  • Page 26 The FTP requests are configured with the Internet wizard of STEP 7 Micro/WIN 32. The configuration data entered here is stored permanently in the file system of the CP 243-1 in a file with the extension .fdb. The data is transferred from the system on which the configuration was created with STEP 7 Micro/WIN 32 to the CP 243-1 via FTP.
  • Page 27 CPU and its duration cannot be predicted. With FTP write requests, the CP 243-1 can read 246 bytes per cycle from the memory of the S7-200 CPU. On the other hand, with FTP read requests, the CP 243-1 can transfer up to 254 bytes per cycle to the memory of the S7-200 CPU.

  • Page 28: Http Server

    Application and properties 1.6 IT communication When a transfer between the FTP client of the CP 243-1 and an FTP server is interrupted, it is possible that only parts of the transferred data are stored on the destination system. In such cases, an error message is output in the S7-200 user program.

  • Page 31 S7-200 system. Predefined HTML pages Note Some of the HTML pages included with the CP 243-1 have linked Java applets. To ensure that these function correctly, the execution of Java applets must be enabled in the Web browser. Communications partners All HTTP clients (for example Web browsers) represent potential communications partners for the HTTP server.

  • Page 32: Configuration And Programming

    Storing the configuration data (Page 36). ● IT services The configuration of the IT services is stored in the file system of the CP 243-1 in the form of configuration files, one each for user administration, FTP client and e-mail service.

  • Page 33: File System

    We recommend that you store files in suitable subdirectories and not in the root directory. The CP 243-1 has no real-time clock for the date or time. For this reason, all files stored in the file system of the CP 243-1 have the date 01.01.1980 and the time 00:00.

  • Page 34: User Administration

    Application and properties 1.9 User administration The file system of the CP 243-1 uses an internal optimization routine to assign all available cells of the flash memory uniformly. When individual memory cells fail due to aging, these cells are detected and marked internally as unusable. Despite this, fast cyclic write or delete access to the file system of the CP 243-1 should be avoided.
  • Page 35 These access rights control authorization to access process data and the file system. The configuration of up to 8 users is stored on the file system of the CP 243-1 in a file with the extension .udb. To increase security, the passwords assigned during the configuration are stored in encrypted form in this file.

  • Page 36: Safety

    Part of the configuration of the CP 243-1 is stored retentively on the S7-200 CPU and part in the file system of the CP 243-1. The validity of the part of the configuration stored on the S7- 200 CPU is checked using by a CRC mechanism. In contrast, no CRC mechanism is used for the part of the configuration stored in the file system of the CP 243-1.

  • Page 37: Data Security

    STEP 7 Micro/WIN 32. Note Access by the server to the S7-200 CPU via the CP 243-1 is possible both in CPU RUN and STOP mode. In STOP mode, however, program variables or I/O values are not updated.

  • Page 38: Reliability Of Communication

    1.10.3 Reliability of communication The CP 243-1 is equipped with a "keepalive" mechanism. This means that the CP 243-1 can recognize the failure of a communications partner or the relevant connection automatically within a configurable period of time. The keepalive time specified when the CP 243-1 is configured is the time after which this internal mechanism is started and an attempt is made to reach the communications partner.

  • Page 39: Connectors

    Connectors Front view: Figure 1-3 Connectors The CP 243-1 has the following connectors: ● Terminal block for 24 V DC power and grounding connector ● 8-pin RJ-45 jack for Ethernet connector ● Male connector for S7 bus ● Integrated ribbon cable with connection socket for the S7 bus The connectors are located under the covers of the front doors.

    Using the FTP server, the contents of the file system can be changed. If there are effects that indicate errors in the file system while the CP 243-1 is running, the contents of the file system on the CP 243-1 should be checked from an FTP client. If necessary, bad files can sometimes be corrected in this way.
