    The 2572-A does not include an Ethernet AUI port, since it is not included in the 802.3 standard for 100Mb operation. However, you can connect to other media types, such as fiber optics, by using a media adapter or an Ethernet switch.

  • Page 11: Functional Overview

    1.3. Functional Overview The 2572-A can operate as both a server and a client. As a server, the module responds to messages sent by a network client, such as a PC running HMI software. As a client, the module initiates messages on command from the PLC to a server, such as another 2572-A module.

    APPENDIX D. IP ADDRESS INFORMATION. 1.5. PLC Command Interface Some 2572-A functions require that you use PLC logic to control the operation of the module. The 2572-A module provides a PLC logic interface for sending messages and processing responses that is identical to the CTI 2572 module.

  • Page 14: Getting Started

    Figure 7 illustrates how the module WX/WY words and the command blocks are used together. The 2572-A writes values in the WX words, the PLC writes values in the WY words. WX1 and WY3 contains bits allow the PLC to monitor and control module global status. WY4 and WX2 contain bits that allow the PLC to trigger commands and monitor command status.
  • Page 15 Using the Module Assuming you have completed the above steps successfully, the 2572-A module is ready for use as a PLC Server. If you wish to implement PLC Client functions, please refer to CHAPTER 5. CAMP CLIENT COMMANDS.

    IP Address numbering conventions. Choosing a Module Startup Method Before the 2572-A will communicate using TCP/IP, the TCP/IP parameters must be set and the module network server must be started. The 2572-A provides several alternative methods to accomplish this task.
  • Page 18 The downside of this method is that, when installing or replacing modules, you must manually configure them. In addition, if you arbitrarily swap 2572-A modules between PLCs, the IP address will move with the module. The effect of inadvertently swapping IP addresses can cause major problems, since communications directed at one PLC would actually be going to another PLC.
  • Page 19 NOTE: The 2572-A will not work in a remote rack using the Profibus Remote Base Controller (RBC). Profibus does not support Special Function modules. The module is allowed to access to the PLC only once during a scan. Ensure that the task codes per scan setting of the PLC is set to eight (8).

    Disable routing for the 2572-A modules. If you want to prevent access to the 2572-A modules from replying to requests outside the local network segment but you want to allow your PC workstations to access the corporate network, disable routing on the 2572-A module. You accomplish this by setting the Default Router IP address to 0.0.0.0.

The server is set up to listen on TCP/UDP port number 1505. The IP address of the default router is 192.168.177.241 (hex equivalent C0.A8.B1.F1).

  • Page 41 NOTE: If TCP is selected and the connection with the target node (remote host) is lost, the 2572-A will report a socket connection error code (such as 240A - Socket not Connected) the next time you attempt to read/write data.

    2572, you will typically set this value to 1505 (the recommended value for the 2572-A PLC server). If you are using UDP and bit 15 of offset 4 is set to 1, then this address becomes the default port number.

  • Page 43: Memory Transfer Commands

    When the command is triggered, the 2572-A reads the local V memory and sends a request message to the remote PLC. When the response is returned from the remote PLC, the 2572-A verifies that the message was properly processed. If not, the 2572-A places the error code in the command block and raises the applicable error bit.
  • Page 44 When the response is returned, the 2572-A verifies the response. If there is no error, the 2572-A writes the data in local V memory. If an error is encountered, the 2572-A will post an error which may be processed by PLC logic.

  • Page 54 PLC Ladder Logic Example The following pages contain a sample of a PLC ladder logic application that implements the 2572-A Client Mode. Client Mode allows the PLC to send a message containing commands and/or data from the local PLC to another network node via TCP/IP. It is typically used to send unsolicited alarm messages or production data based on an event detected by the PLC.
  • Page 55 PLC lowers the command trigger and the 2572-A module has successfully completed the command. If there is an error, the 2572-A will raise the error bit. In this case, it will not lower the command busy bit until the PLC sets the error acknowledge bit. When the command busy bit is lowered, the command cycle is complete and the 2572-A can accept another command in the command slot.

Although many of the 2572 based functions of CTIDiag are no longer supported by the 2572-A, it can be used for such functions as setting the module IP address via the serial port and for generating CAMP message traffic to test the 2572-A server.

    The Command Block is subject to access and change by the module anytime after CMD TRIG is asserted (time C) until CMD BUSY is cleared (time F). Thus, the Command Block should not be changed by the PLC at any time between time C and F. CTI 2572-A Installation and Operation Guide...

  • Page 107: Figure 14. Uncoupled Mode Timing

    NOTE: As long as the 2572-A detects that CMD TRIG is high when CMD BUSY is lowered, it will execute the same command again, It will not re-read the Command Block from the PLC. Therefore, if you wish to change the command to the module, the PLC logic should clear CMD TRIG and ensure CMD BUSY is cleared before changing the contents of the Command Block or the associated Command Slot.

    PLC ERR is clear. Since the ERROR ACK signal is sampled only when CMD ERR or PLC ERR is asserted, PLC logic can leave the ERROR ACK bit on, if you wish to ignore all errors. CTI 2572-A Installation and Operation Guide...

  • Page 110: Figure 17. Command Abort Timing

    Depending upon the nature of the command and circumstances of execution, some commands cannot be aborted. NOTE: Setting all four abort triggers and asserting the module reset bit in WY3 will cause the module to perform a complete reset. CTI 2572-A Installation and Operation Guide...
  • Page 111 With the notable exception of Module Reset (all four abort triggers are set along with the module reset bit) the command slots are totally independent. Unless the commands are directed to a common resource, the command slots should have no effect on each other. CTI 2572-A Installation and Operation Guide V1.3...

    224 – 239 are used for Class D - IP multicast. Private IP Addresses If you are planning on connecting to the 2572-A modules via the Internet, you must obtain a set of IP addresses from the Internet Assigned Numbers Authority (IANA). Contact you network administrator http://www.isi.edu/div7/infra/iana.html.

    The Port Number identifies a particular process or service offered by the host. Some services, such as echo server, are provided via standard "well known" port numbers. For the 2572-A PLC Network Server facility, you can configure the TCP/UDP port number.

  • Page 121: Appendix F. Updating Firmware

    APPENDIX F. Updating Firmware Overview The 2572-A stores all firmware in flash memory. This allows the firmware to be upgraded in the field, eliminating the need to replace physical PROMS. There are two types of firmware used with the 2572-A, the application firmware and the boot loader firmware.

    The TFTP Server must be on the same IP subnet as the 2572-A module. NOTE: Avoid updating the 2572-A while HMI or other clients are attempting to communicate with the module. This will slow the file download considerably and may cause the download process to terminate without completion.
