Diagnostic data
Using the SFB 52 you can access the diagnostic data of the module anytime. Since this
module does not support a process alarm, the diagnostic data serve to provide information
on this module.
Data set 1 is structured as follows:
Byte Bit 7 ... 0
0 0 (fixed)
1 Bit 3 ... 0: Module class, 1000
b
: function module
Bit 4: Channel information available
Bit 7 ... 5: 0 (fixed)
2 0 (fixed)
3 0 (fixed)
4 Bit 6 ... 0: Channel type, 76h: counter module
Bit 7: Further channel types available, 0: no, 1: yes
5 Number of diagnostic bits output by the module per channel (here 00
h
)
6 Number of channels of a module (here 02
h
)
7 ... 15 0 (fixed)
