New features in Version 4
  • With the new upgrade, the PLCcomS7 Library achieves a significant performance increase for cyclically recurring read accesses.
    A major innovation is the introduction of new "ReadItemCollection Objects", to which the variables to be read individually (e.g. individual DINT values) are added.
    When reading, these variables are combined to optimum read accesses to the corresponding PLC. Thus, the necessary read accesses to the respective PLC are reduced to a minimum, which means a much improved performance, as opposed to individually requested variables.
    Something else that is also omitted is the summary of variables into a stream by the software developer - this means that the development time is reduced significantly and this aspect also greatly simplifies the handling.
    Internal process changes also ensure improved performance and stability.
