  • Page 7: Chapter 1. Product Overview

    The 2572-B Ethernet TCP/IP module provides network services for CTI 2500 Series® Classic controllers and Siemens SIMATIC 505® programmable logic controllers. The 2572-B module is designed to install in a CTI 2500 Series classic base or a Siemens Series 505® base. Employing a new microprocessor and related components, the 2572-B module is a direct replacement for the 2572-A Ethernet TCP/IP module.

  • Page 8: Compatibility

    2500C-2572-B module. HMI and SCADA workstation drivers that can access data in CTI 2500 Series Classic controllers via the 2572-A or 2572-B also work with the 2500C-2572-B Module to access data in CTI 2500 Series Compact controllers.

    INFORMATION for a description of the IP Address numbering conventions. Choosing a Module Startup Method Before the 2572-B will communicate using TCP/IP, the IP address and related parameters must be set and the module network server must be started. There are two startup options, described below.
  • Page 10 Many HMI drivers and OPC servers will allow you to select either TCP (Transmission Control Protocol) or UDP (User Datagram Protocol) for delivering messages. The 2572-B client functions also allow you to choose between the two. The following information is provided to help you determine which is right for your situation.

  • Page 14 SW11: PLC Interface Mode. This switch allows you to select a PLC interface that is compatible with the CTI 2572 module and other Special Function I/O modules. By default, the 2572-B module uses a high performance interface mode that increases the amount of data per scan that can be transferred to and from the PLC and sets the task codes per scan to 8.

    The 2572-B is configured as a Special Function module with 2 WX and 6 WY words. In the following example, the 2572-B module is installed into slot 1 on I/O base 0 and will be logged in starting at address 1. Your configuration may differ.

    3.3. Normal Operation Server Operation To use the 2572-B module servers, including the CAMP server, Modbus TCP server, or EtherNet IP Server, no PLC logic is required. You simply provide a client application that communicates with the module. For example, your HMI application, using a CAMP driver or OPC server that supports CAMP, can be used to read and write PLC data.

    The EIP Server starts automatically when the module is started up. No additional configuration is required. 6.4. Application Example The following example illustrate how to configure a Control Logix system to communicate with the 2572-B. The example reads unsigned integers stored in V memory and writes a block of signed integers to V memory.

Specify the Communication options for each Message Block. This includes the path to the target 2572-B module. Defining the Control Logix Data Tags First, we will need to define some Control Logix tags.
  • Page 30 NOTE: Your logic should use a timer (or similar means) to initiate the message block. Allowing the message to execute every scan could create excessive loading on the 2572-B modules. Configuring the Read Message Block This message will read 100 unsigned integers from V memory starting at V501. Clicking on the ellipsis button will display the configuration dialog box.
  • Page 31 The path specifies the route from the controller to the destination. In this case, we will send the message to the backplane (1), to the Ethernet module located in slot 3, out the Ethernet port (2), to the 2572-B module whose IP address is 192.184.177.225.

  • Page 33: Chapter 7. Plc Command Interface Overview

    7.1. Module WX/WY Words The 2572-B module logs in as a Special Function module using two WX words and six WY words. PLC logic uses the WY words to control module operation and the WX words to monitor module operation.

    Values for the command block entries are shown in both hexadecimal and decimal (integer) format. Using your PLC programming software, you can configure a chart to display the values either way. CTI 2572-B / 2500C-2572-B Installation and Operation Manual...

  • Page 35: Wx/Wy Command Block Interaction

    To use the module command interface, your PLC logic should: 1. Load a Command Slot with the address of the desired command block, 2. Set a corresponding trigger bit in WY4 to cause the 2572-B to read the command block and execute the command.

  • Page 37: Chapter 8. Start Network Services Command

    It remains on until the network parameters have been successfully set. While the 2572-B module is waiting on PLC logic to trigger the Start Network Services command, the Network Status (NS) LED will flash.

The examples in this manual assume that this will be set to 1505 decimal, which is a de-facto standard for 2572 and 2572-A modules.
  • Page 39 NOTE: When you trigger the Start Network Services command while the command block contains invalid data, the 2572-B will return an error code and then halt. To recover, you must correct the command block entry and restart the module. When you are setting up the various IP addresses and subnet mask, you should set up your PLC programming software to display the words in hexadecimal.
  • Page 40 Start Network Services Command Block Example The following command block can be used to start up the 2572-B network server at IP address 192.168.177.08 (in hexadecimal notation this is C0.A8.B1.08). The server is set up to listen on TCP/UDP port number 1505.
  • Page 41 OMMAND RIGGER The N bit will be raised by the 2572-B at any time the network configuration parameters are not set. Therefore this logic will re-execute the Start Network Services command if the 2572-B is restarted for any reason. NOTE: Do not use retentive relays in this logic.

  • Page 43: Chapter 9. Camp Client Commands

    The CAMP client commands are used when you wish to use PLC logic to initiate communications with another IP host, such a CTI communications module or a CTI 2500 Series controller. You can also use this capability to o send unsolicited data to your HMI application. For example, you might use this function to report alarms to a supervisory PC, avoiding the requirement to continuously poll for alarm data.

  • Page 45 NOTE: If TCP is selected and the connection with the target node (remote host) is lost, the 2572-B will report a socket connection error code (such as 240A - Socket not Connected) the next time you attempt to read/write data. After the error is acknowledged, the 2572-B will complete error recovery by automatically closing the socket.

When the response is returned from the remote PLC, the 2572-B verifies that the message was properly processed. If not, the 2572-B places the error code in the command block and raises the applicable error bit.

    CMD TRIG is turned off. Time F will be delayed as required until CMD TRIG is off. At time F (equivalent to time B), both CMD TRIG and CMD BUSY are low and a new cycle can begin whenever the PLC asserts CMD TRIG. CTI 2572-B / 2500C-2572-B Installation and Operation Manual...
  • Page 103 The Command Block is subject to access and change by the module any time 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-B / 2500C-2572-B Installation and Operation Manual...
  • Page 104 NOTE: As long as the 2572-B 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...

  • Page 107 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-B / 2500C-2572-B Installation and Operation Manual...

    The octets of the IP address where the corresponding octet of the subnet mask is 255 belong to the Network ID and the octets of the IP address where the corresponding octet of the subnet mask is 0 belong to the Host ID. CTI 2572-B / 2500C-2572-B Installation and Operation Manual...
  • Page 111 The Network Mask must allow at least two bits of host address. In addition, a network mask which causes the derived host ID to be 0 or a broadcast address (all Host ID bits set to 1) should not be used. CTI 2572-B / 2500C-2572-B Installation and Operation Manual...

    Selecting an IP Address In order to perform its functions, the 2572-B requires a fixed IP address. If you are connecting to an existing network, you should obtain an unused static IP address and the network subnet mask from the network administrator.
