B.2.7 Module diagnostic data
The module diagnostic data is assigned to the function num
bers 2008 to 2199. There are 4 diagnostic information items
in 4 consecutive bytes for each module. The function num
bers of the diagnostic data of the faulty module are therefore
calculated as follows:
Function no. = 2008 + (4 * module number)
+ information no.
You can ascertain the module number of the first faulty mo
dule with the aid of the system diagnostic data (function
no.1937).
The following module diagnostic data is available:
Function no. 1)
Module diagnostic data
2008 + m * 4 + 0 Number of the first faulty channel
2008 + m * 4 + 1 Module error number
2008 + m * 4 + 2 Information 2 (reserved)
2008 + m * 4 + 3 Information 3 (reserved)
1) m = module number (0 ... 47)
