Except where noted, the term “PCLTA-20” used in this guide refers to both cards. Echelons PCLTA-20 card is a high-performance LONWORKS® interface for desktop, and embedded personal computers equipped with a 32-bit PCI interface and a compatible operating system. Designed for use in LONWORKS networks that require a PC to monitor, manage, or diagnose the network, the PCLTA-20 card is ideal for industrial control, building automation, and process control applications. The PCLTA-20 card features support for a wide range of transceivers, downloadable memory, a network management interface, and Plug n Play capability with Microsoft® Windows 95, 98, Me, NT, and 2000 operating systems. The PCLTA-20 protocol analyzer requires Windows 95 or 98. The four versions of the PCLTA-20 interface with integral twisted pair transceivers support the TP/FT-10 (Model 74401), TP/XF-78 (Model 74402), TP/XF-1250 (Model 74403), and TP-RS485 (Model 74404) channels, respectively. The Model 74405 PCLTA-20/SMX interface and the PCLTA-20 Protocol Analyzer support SMX transceivers, and may therefore be used on a wide range of channels, including Echelons TP/FT-10 free topology and PL-10, PL-20, and PL-30 power line channels. The PCLTA-20 card can be used as an LNS Fast Network Interface, a standard LNS network interface, or a LonManager API-compatible interface. The LONWORKS PCLTA-20 Protocol Analyzer provides LONWORKS manufacturers, system integrators, and end-users with a rich set of Windows tools and a PCLTA-20 card for observing, analyzing, and diagnosing the behavior of LONWORKS networks. In addition to providing the network analysis functionality, the PCLTA-20 card included with the protocol analyzer also provides all the functionality of the PCLTA-20 PCI Interface. Introduction The PCLTA-20 card provides any PC equipped with a 32-bit PCI interface and compatible Windows operating system with access to a LONWORKS network. Installation software for the PCLTA-20 card is included with the Model 33100-20 LONWORKS PCLTA-20 Protocol Analyzer, the Model 37000 LonMaker Integration Tool, the Model 37200 LNS DDE Server, the Model 34309 LNS Application Developers Kit, and the Model 58030-01 Connectivity Starter Kit (which must be purchased separately). The software provides a software-based control panel and a software driver for Microsoft Windows 95, 98, Me, NT, or 2000 operating systems (the PCLTA-20 Protocol Analyzer requires Windows 95 or 98). Installation software also is available on Echelons web site at The control panel provides a convenient means of setting and modifying installation parameters, as well as displaying error messages. The adapter supports Windows 95, 98, Me, and 2000 Plug n Play operation, simplifying installation and use. The PCLTA-20 card operates at 10MHz and, depending on the model selected, includes either an integral twisted pair transceiver or an SMX transceiver interface. For models with an integral twisted pair transceiver, the network connection is made via a removable screw terminal block. As shown in figure 1.1 below, the LNS network operating system allows any number of installation, maintenance, monitoring, and control devices to exist in a system and to adapt to network configuration changes automatically. That is, it allows users to reconfigure the system from any user interface device anywhere on the network and ensures that all monitoring and control stations are always up-to-date with respect to the systems configuration. When used with the appropriate software, the LNS Fast Network Interface functionality of the PCLTA-20 card allows the attached host to tap into the LNS infrastructure as a client or server application.The card also permits the host PC to act as a LONWORKS network device, running application-specific programs while the card handles lower layer functions such as media access control, collision avoidance, and message validation Firmware for the card is downloaded from the host PC. This allows the card to be updated as new versions of the software and firmware are released, without modifying or physically accessing the PCLTA-20 card. This feature extends the useful service life of the card, and minimizes the cost and time associated with software and firmware updates. The card is provided with 32Kbytes of off-chip RAM for use as network and application buffers.Audience This manual is intended for developers and end users of LONWORKS systems using the PCLTA-20 card, and for network integrators and end users of the PCLTA-20 Protocol Analyzer. Content This manual provides detailed technical specifications on the electrical and mechanical interfaces and operating environment characteristics for the PCLTA-20 card. Related Documentation The following Echelon publications are suggested for additional information: LONWORKS® SMX Transceiver Installation Instructions (078-0145-01) LONWORKS FTT-10A Free Topology Transceiver Users Guide (078-0156-01) LONWORKS Junction Box and Wiring Guidelines Application Note (005-0023-01) LONWORKS TPT Twisted Pair Transceiver Module Users Guide (078-0025-01) LNS for Windows Programmers Guide (078-0177-01) LonManager Protocol Analyzer Users Guide (078-0121-01) LonMaker Users Guide (078-0168-02) LNS DDE Server Users Guide (078-0170-01) PCLTA-20 Configuration PCLTA-20 configuration is accomplished by using the LONWORKS Plug n Play control panel application. Open the control panel application by selecting the LONWORKS ® Plug n Play icon in the Windows Control Panel. Figure 1.2 PCLTA-20 Control Panel and IconThe LONWORKS Plug n Play control panel application is divided into three parts: a device selection area, a general settings area, and a control section. The device selection area contains configuration settings and diagnostic controls that are specific to an individual PCLTA-20 card and its device driver. The general settings area contains settings for all PCLTA-20 cards used with the PC. The control section contains buttons for accepting or canceling the changes made in the control panel, as well as a Help button. PCLTA-20 Initialization In most cases, PCLTA-20 initialization occurs automatically upon installation of the card and subsequent power-up of the computer. Manual initialization will be required following software installation to a directory other than c:lonworks, or following the moving of the PCLTA-20 system images. To manually initialize the PCLTA-20 card, verify that the control panel applications System Image Path entry is correct, then click the Apply button. An error will be reported if an attempt is made to view the transceiver type before the PCLTA-20 card is initialized. Testing the card with the Diagnostics button, assuggested by the error message, produces the diagnosis: “Image file not found.” In this case, return to the control panel applications main window and manually initialize the PCLTA-20 card.Device Specific Settings The PCLTA-20-specific options consist of five separate controls (figure 3.2). These controls are defined as follows:Figure 1.3 PCLTA-20-specific ControlsDevice Selected Controls which PCLTA-20 card is selected for configuration. The PCCLON1 and PCCLON2 drivers are installed by the installation software. If additional drivers have been manually installed, they also will be available. Automatic Flush Cancel For non-LNS images, this function controls whether the device driver will automatically force the network interface for the selected PCLTA-20 card to leave the post-reset flush state whenever it is reset; an LNS network interface does not and cannot come up in the flush state. The post-reset flush state prevents any inbound or outbound network traffic following a reset. If this box is not checked, it is up to the client application to manage this state. If it is checked, the device driver will automatically allow network traffic to resume. The default is checked. NI Application Controls the type of image or application to be used on the PCLTA-20 card. This selection is handled automatically by the protocol analyzer software. For all other applications, a PCLTA-20 card can only hold one image at a time. Loading a new image will replace the currently loaded image. The choices for these images are determined by the image files (.NBI extension) found in the system image path specified under General Settings. Some of the possibilities include the following: PCL10VNI, the LNS Fast Network Interface image (for use with LNS 3 and newer) NSIPCLTA, the LNS network interface image (for use with LNS 1 and LNS 2 only) PCC10L7, the basic network interface application image Transceiver Opens the PCLTA-20 Transceiver dialog (figure 1.4). Choosing this option will retrieve the transceiver configuration of the selected PCLTA-20 card. If there is no PCLTA-20 card currently installed in a PCI-bus slot, a message appears stating that the operating system has removed, or has not loaded, the PCLTA-20 device driver.Figure 1.4 PCLTA-20 Transceiver Dialog BoxThe Transceiver value specifies the transceiver type for the selected PCLTA-20 card. The default transceiver is a TP/FT-10 compatible transceiver. Other standard transceiver configurations, and a custom configuration, may be chosen. The Custom Properties values are not accessible unless the Custom transceiver type is selected: you cannot modify the transceiver type as it is a product of the transceiver ID (XID), however, if the XID is custom then you can modify the fields using the Custom Properties dialog box. If an incorrect transceiver type error is received while modifying the transceiver type, click the Apply button, then proceed to modify the transceiver type. The Custom Properties area contains custom transceiver properties. The information in this area reflects the current configuration within the PCLTA-20 card. It will not change until a transceiver is selected, and then configured using the OK or Apply buttons.When configuring a custom transceiver or adding custom parameters for a standard transceiver, the Custom Properties Raw Data values must be entered as hexadecimal values separated by dashes. Further explanation of Raw Data values can be found in the LonBuilder® Users Guide. Diagnostics Opens the PCLTA-20 Diagnostics dialog.
