METHOD FOR THE CONFIGURATION AND PARAMETERISATION OF FIELD BUS SUBSCRIBERS AND ENGINEERING SYSTEM

摘要

The invention relates to a method for the configuration and parameterisation of field bus subscribers (Ctr, Dev), which are connected to one another via a field bus (F), wherein at least one first field bus subscriber (Dev) is designed to provide and/or receive process data (IO) and a second field bus subscriber (Ctr) is designed to allow a user program (AP) to run, wherein, in a first step (S1), a topology (Topo) is determined by a configuration tool (CT) with configuration parameters (CP) of the field bus subscribers (Ctr, Dev) in a configuration file (CD), and in a second step (S2), the first field bus subscriber (Dev) is parameterised for a later communication via the field bus (F) with at least one configuration data set (Dconf) comprising at least one first part (GDI) of the configuration file (CD), wherein, in a third step (S3), from the configuration file (CD) and further code portions (C1,..., C5) from a program library (PB), an object-orientated class (class) is generated with elements (E) and functions (f) for communication between the second field bus subscriber (Ctr) and the first field bus subscriber (Dev), wherein, in a fourth step (S4), the class (class) is instanced in the user program (AP) of the second field bus subscriber (Ctr), and in the execution of the user program (AP), the functions (f) are used for communication, whereby access (Z) to the process data (IO) is permitted.
