  • Page 5: Safety Instructions

    The supply connection, as well as the signal and sense leads, must be installed in such a way that electromagnetic interference does not adversely affect device functionality (HBM recommendation: ”Greenline shielding design”, downloadable from the Internet at http://www.hbm.com/Greenline). Automation equipment and devices must be covered over in such a way that adequate protection or locking against unintentional actuation is provided (such as access checks, password protection, etc.).
  • Page 6 General dangers due to non-observance of the safety instructions The MP70DP module complies with the state of the art and is safe to operate. If the equipment is used and operated inappropriately by untrained personnel, residual dangers may arise.
  • Page 7 Prevailing regulations must be complied with at all times. Residual dangers connected with measurement technology need to be pointed out. Any risk of residual dangers when working with the MP70DP is pointed out in this introduction by means of the following symbols: WARNING...
  • Page 8 Greenline shielding only (conncect the shield of the transducer cable to the plug housing). The cables of the digital inputs and outputs of the MP70/MP70DP should not be longer than 30 m or should they be routed outside the building where the system is located.

  • Page 16: Linking Several Modules

    Fig. 3.4: Connecting the ribbon cable Several measurement modules (MP01, MP30, MP55, MP60) can be linked to the MP70DP via a ribbon cable. This cable provides the local connection of supply voltage and synchronisation between the modules. No more than eight modules should be interlinked via a ribbon cable.

  • Page 17: Connections

    Please note the safety instructions before putting into service the device. NOTE Use standard HBM cable for the transducer connection. When using other shielded, low-capacitance measuring cable, connect the transducer cable shielding to the connector housing in accordance with the HBM Greenline concept (Internet download http://www.hbm.com/Greenline).

  • Page 22: How To Connect To A Plc

    The steps in successfully connecting to the Profibus: 1. Physically connect the device to the Profibus (see page 25 and page 18) 2. Configure the device parameters (can also be carried out using HBM‘s “PME-Assistent“ software). 3. Configure the Profibus message and set up its parameters with the aid of a configuration tool (such as Step7) and GSE files, or manually as shown in chapter 10.1 and 10.2.

  • Page 23: Configuring And Assigning Parameters

    • Start your configuration program (e.g. Step7; if you have no configuration program, proceed to chapter 10.2) • Load the HBM GSD file (PME system CD incl. GSD/GSE files for PME) • Add an HBM device (Hardware catalog) • From the hardware catalog choose the configuration you want on the Profibus.
  • Page 24 PME-MP70DP • Double-click on the configured entries to open the properties window and select the required parameters. Abb.5.3: Setting parameters Notes for users of the Simatic S7 PLC: • To download consistent data of 3 bytes or over 4 bytes, use special function modules SFC14 to read and SFC15 to write.

  • Page 25: Putting Into Service

    PME-MP70DP Putting into service D Use the ribbon cable to link the modules (a maximum of 8) to the MP70DP (see Fig. 4.5, page 20). This establishes the supply voltage link, the CAN-BUS link and synchronisation link between the modules.
  • Page 26 D Connect the Profibus line to the Profibus connection on the front of the MP70DP (see page 20). Make sure that the line terminating resistance of 120 Ω is connected at the first and last bus users (there is usually a slide switch for this on the Profibus connector housing).
