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 7 6 5 ... 0: Description
0 0 0 ... 63: No. of the 1st
faulty O channel
1 0 0 ... 63: No. of the 1st
faulty I channel
0 1 0 ... 63: Module fault
1 1 0 ... 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 (servicing required).
