Request diagnostic information (Slave_Diag)
The diagnostic data are requested by the SPC200 with the
function Slave_Diag. A description of this function can be
found in chapter 5, in the section Diagnosis via PROFIBUS−DP.
Cyclic exchange of data (Data_Exchange)
The cyclic exchange of data is accomplished with the function
Data_Exchange. With this function the output data for the
SPC200 are transmitted as an byte string of length x.
The length of the byte string depends on the size of the adĆ
dress range used for the exhange of data. It can therefore be
of a different size for input data and output data (Inp_Data,
Outp_Data). This results per byte in an byte string length of 1.
Please note
With the function Data_Exchange the SPC200 awaits the
status description for the internal inputs (outputs of the
master). The status of the internal outputs (input informaĆ
tion for the master) is sent as a reply telegram to the
master. The length of the data telegrams depends on the
size of the configured address range.
