Description
This command reads out the present PROFIBUS input and output buffers. The output buffer handles the data flow from the control system to the Drive, and the input buffer handles the data flow from the Drive to the control system. Each buffer is 20 bytes long (telegram length) and is put together from the PKW section (8 bytes. i.e., 4 words) and the PZD section (12 bytes, 6 words). The individual bytes are in hexadecimal format.
PIOBUF provides 20 bytes of output buffer in the first line, and 20 bytes of input buffer in the second line.
If the communication over the PROFIBUS is interrupted or faulty, then a fault message ERR [PIOBUF] NO DATA EXCHANGE SPC3 - INTERRUPT is generated.
