Viewing PROFIBUS Slave Configuration
The Configuration Screen displays many specific SPC3 ASIC diagnostic data
useful to ProSoft Technology Technical Support and advanced PROFIBUS
users. Additional information can be found in the SPC3 specification.
Station Address
= The configured station address set by the user
DOut Len is the total number of output bytes with the S1, S2 and S3 values being
pointers to the 3 output buffers in the SPC3 chip.
DIn Len is the total number of input bytes with the S1, S2 and S3 values being
pointers to the 3 input buffers in the SPC3 chip.
Diag1Len should always be 6 to represent the minimal number of diagnostic
bytes and S= pointer in SPC3 chip to this data.
Diag2Len is the extended diagnostic buffer length and S is a pointer to this data
in the SPC3 chip.
Aux1 Len: (see SPC3 specification) and S is a pointer to this data in the SPC3
chip.
Aux2 Len: (see SPC3 specification) and S is a pointer to this data in the SPC3
chip.
SSA Len is not used and should be 0 and its pointer S is N/A.
Param Len = is the length of the parameter data for the slave with S as the
pointer in the SPC3 chip to the data.
