  • Page 7: Preface

    The PLX51-DLplus-232 can be used to log data at a remote site with limited communication with its base. The PLX51-DLplus-232 is also used to store records on mobile equipment such as trucks, drilling rigs, or snow plows. Once the equipment returns back to its base, the historical data can be uploaded and transferred to a more permanent storage device.

  • Page 8: Features

    Non-Historian Option Features The PLX51-DLplus-232 provides temporary extensive on-board storage capability for storing process tags. A total of 16,777,216 records can be stored in its non-volatile memory. Each record consists of the following data: Parameter Link UTC Time includes: Year, Month, Day, Hour, Minute, Second, Milliseconds.
  • Page 9 The Log Index is managed by the PLX51-DLplus-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 11: Installation

    2 INSTALLATION Module Layout The PLX51-DLplus-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 12 Figure 2.2 – Front and top view The PLX51-DLplus-232 has four DIP switches at the top of the enclosure as shown above. DIP Switch Description DIP 1 Used to force the PLX51-DLplus-232 into “Safe Mode”. When in “Safe Mode”, the PLX51-DLplus-232 does not load the application firmware.

  • Page 13: Module Mounting

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

  • Page 14: Power

    NOTE: 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-DLplus-232, and not to the other Serial device. Figure 2.6 - RS232 connector Ethernet Port The Ethernet connector should be wired according to industry standards.

  • Page 15: Setup

    By default, the PLX51-DLplus-232 has DHCP (Dynamic Host Configuration Protocol) enabled. Thus, a DHCP server must be used to provide the PLX51-DLplus-232 with the required network parameters (IP address, subnet mask, etc.). There are a number of DHCP utilities available.
  • Page 16 Within the PLX50 Configuration Utility, click on T > DHCP S OOLS ERVER Figure 3.2 - Selecting DHCP Server Once opened, the DHCP server listens on all available network adapters for DHCP requests and displays their corresponding MAC addresses. Figure 3.3 - DHCP Server NOTE: If the DHCP requests are not displayed in the DHCP Server, it may be due to the local PC’s firewall.
  • Page 17 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-DLplus-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 18: Network Settings

    It is possible to force the PLX51-DLplus-232 into DHCP mode by powering up the device with DIP switch 2 in the On position. A new IP address can be assigned by repeating the previous steps. NOTE: It is important to return DIP switch 2 back to Off position, to avoid the PLX51-DLplus-232 returning to a DHCP mode after the power is cycled again.

    4 RSLOGIX 5000 CONFIGURATION Add Module to I/O Configuration The PLX51-DLplus-232 can operate in both a Logix “owned” and standalone mode. When the PLX51-DLplus-232 operates in a Logix “owned” mode, the PLX51-DLplus-232 needs to be added to the RSLogix 5000 / Studio5000 IO tree, as a generic Ethernet module.
  • Page 34 RPI. NOTE: Although the PLX51-DLplus-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-DLplus-232 processor.

    The Get Cache Records request can extract subsets of records by using the record index. This is a low-level approach where the application is expected to manage the record indices. The PLX51-DLplus-232 stores records in a 16 million record circular buffer, using a LogIndex and UnloadIndex. Each time a record is logged, the LogIndex is incremented.
