Data Set 3 - Leuze electronic MSI 400 Series Manual

11.5.3 Data set 3

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" [chapter 3.3.5].
Error and state information for the modules
Data set 3 contains the state information for the modules that will be transferred to the network.
Ten bytes are transmitted for each controller module. For each MSI-EM-I8 or MSI-EM-IO84 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
i
Ä Reserved (for future use) = static 1 (no state change)
Ä Not used (can be 0 or 1 ), both values occur.
Ä If there is no module, all values - including the reserved values - are set to logical 1.
