Example 2: Reading out current error numbers of module 1
With the aid of the module number of the faulty module, you can ascertain the function numbers of the
relevant module diagnostic data (è C.6 Module diagnostics data).
Module diagnostic data can be e.g.:
– The number of the faulty channel
– The module error number.
With the following function number, you can ascertain e.g. the module error number of module 1:
– Function number = 2008 + 4 * 1 + 1 = 2013
– 2013 Dec. = 11111011101 Bin
