The function blocks are object-oriented and characterized by a self-contained, more or less complex function. The user
configures the input parameters through which the function block is adapted individually to its task within the associated
system.
Thanks to strongly object-oriented encapsulation of complex system functions within one function block, comprehensive
system programs can be set up with a few function blocks. The blocks are linked to each other via a small number of PLC
variables.
The status of all objects is indicated through a large number of different output variables at the function blocks. This simplifies
the connection of HMI and visualization systems.
For system operators this has the following advantages for system setup and operation:
– faster system program development
– faster parameterization and commissioning of the systems
– guarantee of a very large range of system functions at all times
– improved readability of programs (prerequisite for long-term maintainability and expandability of the systems)
– improved reusability of templates for systems or system components
– faster familiarization of personnel
– simple extension of existing systems
– better program documentation
Notice:
A link to an overview of all meter blocks (meters supported by the TwinCAT PLC M-Bus library) can be found at the end of
this document. Beckhoff can create new meter blocks: To this end, Beckhoff requires a sample device and an M-Bus protocol
description from the device manufacturer.
