    Connection to a PC (HOST) The PMX data acquisition system is connected to a PC via the standard Ethernet port, and can be parameterized and operated via the internal web server. You can connect to an automation system via the digital and analog inputs/outputs, as well as via the PMX's fieldbus interfaces.
  • Page 19 The PX878 input/output card has a total of eight digital inputs, eight digital outputs, and five analog voltage outputs. The PMX can be controlled by this, as well as operated with a downstream control (PLC). All real or calculated measurement signals can be freely assigned to the outputs.

  • Page 28: Pmx Web Server And Software

    PMX web server and software A PMX web server, including Help, is integrated into the device. The web server also has a function which can download new PMX firmware and web server versions to the PMX. The web server includes a help for operating and managing the PMX (click on the Help icon in the top right corner of the overview menu).
  • Page 29 All real and calculated measurement channels are measured, as are the digital inputs and outputs. Digital inputs and outputs are represented as binary coded values. The PMX supports up to three sample rates, which can be set independently of each other. The sample rates can then be assigned to individual measurement signals.
  • Page 30 Software driver The PMX command set, a .NET API and a LabVIEW driver are provided for you to create custom applications. This allows you to implement your own operating concepts and integrate them into existing software solutions.
  • Page 31 Information Driver versions 2.0 or higher are required for firmware version 2.00 or higher. All commands in the PMX command set can be used as low-level commands (see chapter 21, ”PMX command set”, page 346). Detailed support and programming examples can be found in the program help of the individual drivers.

  • Page 32: Protection / Housing / Shielding Design

    Lay the cable shields directly at the control cabinet input on a grounding bar and route the sense leads as short as possible to the PMX (Fig. 6.1). Also connect the PMX to the grounding rail via the grounding terminal on the PMX housing (Fig. 6.2), and ground the control cabinet and grounding rail.

  • Page 37: Support Rail Mounting

    5. Attach the PMX to the support rail (4). Notice Device damage by dropping the PMX due to difficulty of attaching/detaching the PMX. HBM recommends using a DIN support rail (DIN EN 60715) with a height of 15 mm. When using a smaller support rail (7.5 mm high), it should be packed, to make it easy to attach/detach the PMX.
  • Page 38 To ensure sufficient grounding of the PMX, the support rail must be connected to functional ground Both the support rail and the PMX must be free of paint and dirt at the mounting loca­ tion. Connect the PMX housing to ground via the grounding screw.

A suitably equipped amplifier imports the transducer characteristics (electronic data sheet), translates them into its own settings, and you can start the measurement.

    On the PX401 and PX460 measurement card, the TEDS module is addressed sepa­ rately via an additional wire (1‐wire TEDS). In the PMX you can preset channel by channel how the PMX is to respond after being switched on or connecting TEDS sensors: Ignore existing TEDS.

    If measurement signals need to be referenced over time with each other for processing and analysis, for measurement data acquisition tasks (DAQ), for example, they must be synchronously recorded. That is why all PMX modules can be synchronized with one another. This ensures simultaneous measurement on all channels. An internal counter in each PMX is used for the purpose.

This determines the number of channels that are copied into the data frame (range 0 … 48). In RSLogix 5000, for example, it looks like this: 2.
  • Page 279 The installed measurement cards provide the signals of the channels in the order of their installation in the PMX rack. The card in slot 1 delivers data starting with channel 1. An empty slot does not supply any channels; only the EtherNet/IP™ channels are all occupied without gaps.

  • Page 289 The WGX001 basic device has a CAN interface according to ISO11898. In conjunction with the CODESYS Soft PLC, you can operate the PMX as a CANopen slave or CANopen master. To do this, add a CAN component and a CANopen stack in CODESYS. The corresponding PMX package and a collection of sample programs for code generation, web visualization and integration of CANopen modules are also included.
