Data set 3
1065967499
Data set 3 (60 bytes) contains the state and diagnostic data for the various modules, with four
(4) bytes per module, with the controller module comprising 3 x 4 bytes. Details: see table
"Meaning of module state bits for secure I/O modules" [ch. 3.3.5, p. 25] .
Error and state information for the modules
Data set 3 contains the state information for the modules that will be transferred to the net-
work.
Ten bytes are transmitted for each controller module. For each SP-SDI or SP-SDIO I/O module,
four bytes are transmitted in the little endian format, e.g. as a 32-bit word, with the first byte
being placed into the least significant byte of the whole number (extreme left) and the fourth
byte into the most significant byte of the whole number (extreme right).
Data set 3 cannot be changed.
NOTICE
• Reserved (for future use) = static 1 (no state change)
• Not used (can be 0 or 1 ), both values occur.
• If there is no module, all values - including the reserved values - are set to logical 1.
