Diagnostic memory data (10 bytes per entry, max. 40 entries) Function no.
1)
Byte
no.
Designation
Description Value 3488 + n
1 Days [day] Number of days
2)
0 ... 255 n = 10 * d + 0
2 Hours [h] Number of hours
2)
0 ... 23 n = 10 * d + 1
3 Minutes [m] Number of minutes
2)
0 ... 59 n = 10 * d + 2
4 Seconds [s] Number of seconds
2)
0 ... 59 n = 10 * d + 3
5 Milliseconds [ms] Number of 10 msec
2)
Additionally: Bit 7 is set if it is the
first entry after Power ON.
0 ... 99
or
128...227
n = 10 * d + 4
6 Module code
3)
Module code of the module which
registered the fault.
0 ... 255 n = 10 * d + 5
7 Module position
[Pos]
Module number of the module which
registered the fault; 63 = fault not
module−related
0 ... 47,
63
n = 10 * d + 6
8 Channel number
3)
Bit 765 ... 0: Description
000 ... 63: No. of the 1st
faulty O channel
100 ... 63: No. of the 1st
faulty I channel
010 ... 63: Module fault
110 ... 63: Reserved
0 ... 255 n = 10 * d + 7
9 Error number [FN] 0 ... 255: Error number (possible
error messages see
section 5.2.3)
0 ... 255 n = 10 * d + 8
10 Subsequent
channels
3)
Number of subsequent channels with
the same fault
0 ... 63 n = 10 * d + 9
1) d (diagnostic event) [NB] = 0 ... 39 ; most current diagnostic event = 0;
2) Measured from the moment the power supply is switched on
3) If the fault number = 0, the content of these bytes is also 0. If the fault number lies
between 128 ... 199 (error class 3), the content of these bytes is not relevant (ser vicing required).
