    Intended use The MP70DP module with connected transducers is to be used exclusively for measurement tasks and directly related control tasks. Use for any purpose other than the above is deemed to be non‐designated use.
  • Page 6 General dangers of failing to follow the safety instructions The MP70DP module is a state of the art unit and as such is failsafe. The device may give rise to residual dangers if it is inappropriately installed and operated by untrained personnel.
  • Page 7 PME-MP70DP Any risk of residual dangers when working with the MP70DP is pointed out in these instructions by means of the following symbols: WARNING Symbol: Meaning: Dangerous situation Warns of a potentially dangerous situation in which failure to comply with safety requirements can lead to death or serious physical injury.
  • Page 8 Greenline shielding concept (place the shield of the transducer cable onto the connector housing). The cables of the MP70/MP70DP digital inputs and outputs that are used should not be longer than 30 meters and should not exit the building in which the system is located.
  • Page 9 PME-MP70DP Conversions and modifications The MP70DP module must not be modified from the design or safety engineering point of view except with our express agreement. Any modification shall exclude all liability on our part for any damage resulting therefrom. In particular, any repair or soldering work on motherboards is prohibited.

  • Page 10: Introduction

    D MP70DP D MP70DPS7 D MP70S7 MP70DP The MP70DP module is a PROFIBUS DP Gateway for the amplifiers of the PME product family. Up to 8 measurement modules (MP01, MP30, MP55, MP60) can be connected to the gateway. Communication between the MP70DP PROFIBUS DP Gateway and the modules is handled by an integrated CAN interface.
  • Page 11 No function The MP70DP module is set up and parameterized via a keyboard and display, or by using the PME Assistant. The PME Assistant provides a user‐friendly interface under Windows for parameterizing the modules (described in the Online Help of the PME Assistant program).
