SICK HIPERFACE DSL - Page 49

Depending on the length of the "long message" answer, the registers are used as fol‐
lows:
Table 24: Data length of the "long message"
Length of the "long message" Register used
8 bytes 20h to 27h
4 bytes 20h to 23h
2 bytes 20h to 21h
0 bytes None
These registers are also for the reporting of error conditions arising from a "long mes‐
sage" operation. If, when accessing a resource, an error due to a "long message" arises
(e.g. invalid data, error in the A/D conversion, time overrun), after the answering mes‐
sage has been received the LOFF bit in the PC_ADD_H register (28h) is set. In this case
the Parameters Channel buffer bytes 0 and 1 contain an error code.
The meaning of the error code depends on the particular HIPERFACE DSL
®
encoder and
is described in detail in the data sheet.
