Function block FB283

Overview
The function block FB283 is an interface block that connects an inverter with basic positioner
to a SIMATIC S7 controller via PROFIBUS/PROFINET.
The block FB283 transfers all of the required process data to and from the drive. It is suitable
for both controlling the basic positioner and for a pure speed-controlled drive.
The FB283 additionally provides the following functions:
● Reading and writing parameters in the inverter.
● Reading out the fault buffer of the inverter.
● Transferring up to 16 traversing blocks when a function is initiated.
● Reading or writing a maximum of any 10 parameters with one job, e.g. for product
adaptation.
A configuration example and a description of the FB283 can be found on the Internet: FB283
