    Date Time stamp with a 50 ms resolution, Tag Name, Data Type, and Value. The PLX51-DL-232 can be used to log data at a remote site with limited communication with its base. The PLX51-DL-232 is also used to store records on mobile equipment such as trucks, drilling rigs, or snow plows.
  • Page 7 Data Logger User Manual The Log Index is managed by the PLX51-DL-232 and incremented each time a new record is stored. The Unload Index is managed externally by the unload service. It is only incremented after a record has been logged successfully to a text file. The records can be unloaded in Logix with the Example Code.

  • Page 9: Installation

    Installation Module Layout The PLX51-DL-232 has three ports at the bottom of the enclosure, as shown in the figure below. The ports are used for Ethernet, RS232 serial, and power. The DC power port uses a three-way connector (+ positive, - negative, and Earth).
  • Page 10 PLX51-DL-232 Installation Data Logger User Manual Figure 2.2. – Module front and top view The PLX51-DL-232 has four DIP switches at the top of the enclosure as shown above. Table 2.1. - DIP Switch Settings Description DIP Switch DIP 1 Used to force the PLX51-DL-232 into “Safe Mode”.

  • Page 11: Module Mounting

    The PLX51-DL-232 provides a DIN rail clip to mount onto a 35mm DIN rail. Figure 2.3. - DIN rail specification The DIN rail clip is mounted on the bottom of the PLX51-DL-232. Use a flat screw driver to pull the clip downward. Once the PLX51-DL-232 is mounted onto the DIN rail, the clip must be pushed upward to lock the PLX51-DL-232 in place.

  • Page 12: Power

    Important: When using a shielded cable, it is important that only one end of the shield is connected to earth to avoid current loops. It is recommended to connect the shield to the PLX51-DL-232, and not to the other Serial device.

  • Page 13: Setup

    Setup Data Logger User Manual Setup Install Configuration Software The PLX51-DL-232 is configured using the PLX50 Configuration Utility environment. This software can be downloaded from www.prosoft-technology.com. Figure 3.1. - PLX50 Configuration Utility Environment ProSoft Technology, Inc. Page 13 of 59...

  • Page 14: Network Parameters

    3.2.1 DHCP Server Settings By default, the PLX51-DL-232 has DHCP (Dynamic Host Configuration Protocol) enabled. Thus, a DHCP server must be used to provide the PLX51-DL-232 with the required network parameters (IP address, subnet mask, etc.). There are a number of DHCP utilities available.
  • Page 15 Click OK when complete. Once the Assign IP Address dialog box has been accepted, the DHCP server automatically assigns the IP address to the PLX51-DL-232 and reads the Identity Object Product name from the device. The device indicates a green background upon successful assignment of the IP address.

  • Page 23: Logix Source

    The Logix Source tab is used to configure tags from Rockwell Automation Logix controllers over EtherNet/IP. The PLX51-DL-232 can read tags from up to three separate controllers. A Target Name must be provided. This acts as a reference to the Logix CIP path.
  • Page 24 Figure 3.18 – Target Browser Window If the Ethernet/IP module is a bridge module, it can be expanded by right-clicking on the PLX51-DL-232 icon and selecting the Scan option.

    Before downloading, the connection path of the PLX51-DL-232 should be set. This path automatically defaults to the PLX51-DL-232 IP address, as set in the PLX51-DL-232 configuration. It can be modified if the PLX51-DL-232 is not on a local network. The connection path can be set by right-clicking on the PLX51-DL-232 icon and selecting the Connection Path option.
  • Page 28 The new connection path can be entered manually or selected by means of the Target Browser. Figure 3.26 - Connection Path To initiate the download, right-click on the PLX51-DL-232 icon and select Download. Figure 3.27 - Connection Path Once complete, you will be notified that the download was successful.

  • Page 30: Rslogix 5000 Configuration

    RSLogix 5000 Configuration Add Module to I/O Configuration The PLX51-DL-232 can operate in both a Logix “owned” and standalone mode. When the PLX51-DL-232 operates in a Logix “owned” mode, the PLX51-DL-232 needs to be added to the RSLogix 5000 / Studio5000 IO tree, as a generic Ethernet module.
  • Page 31 Refer to the technical specification section in this document for further details on the limits of the RPI. Important: Although the PLX51-DL-232 is capable of running with an RPI of 10 ms, it is recommended to set the RPI to 500 ms to avoid unnecessary overloading of the PLX51-DL-232 processor.
