    The method of writing parameters is similar to the method of reading them. Become familiar with Reading Parameters, (above), before attempting to write any parameters. Writing parameter values to the SITRANS LR 300: Write the primary index value into R43,999.

  • Page 89: Communications: Data Types

    Communications: Data Types The SITRANS LR 300 parameters do not always use integers to hold values. For the convenience of the programmer, those values are converted to and from a 16-bit integer number. This section describes the conversion process. Numeric Values Numeric parameter values are the most common.

    Profibus PA is an open industrial protocol. Full details about Profibus PA can be obtained from Profibus International at www.profibus.com The SITRANS LR 300 is a Class A, Profile Version 3.0, PA device. It supports Class 1 Master for cyclic data exchange, and Class 2 for acyclic services: (see page 115 for details).

  • Page 117: Bus Termination

    Input and output information is always requested at every bus scan and is set up as cyclic data. Configuration information is only needed periodically and is set up as acyclic data. Cyclic Data When you configure the SITRANS LR 300 on the Profibus PA bus, there are 4 slots available for modules. Note: Each of the slots has to have a module defined in it.
