Error number 1 Wrong firmware
indicated in 2 Type of addressing not permitted
KF format 3 Module address not permitted
4 Module address not in increments of 32
5 DB no. (DB-A) or DB type not allowed
6 DB-A does not exist or too short
7 DB-B does not exist or too short
8 DB-C does not exist or too short
9 Command not permitted
10 Message number (T-NR) not permitted
11 DB no. (DB-A’) or DB type not allowed
12 DB-A’ does not exist or too short
13 DB-C’ does not exist or too short
14 Command ”LE” or ”automatic reading after self-tuning” is
selected in FB 162, but not released on the IP 244, i.e. main
control byte 1, bit 2 is at present 0
15 Module cannot be addressed at present because self-tuning
function active
16 Timeout during cold restart
17 Acknowledgement delay (timeout) IP 244 (not valid with the
S5-115U, CPU 941 to CPU 944 and CPU 941B to CPU 944B)
26 Wrong CPU (only with the S5-115U, CPU 945)
–128 Acknowledgement delay (timeout) (only with the S5-115U,
CPU 941 to CPU 944 and CPU 941B to CPU 944B)
(indicated in ISTACK:FB162 condition code QVZ;
status FY255 = KF –128)
AFEH: Q, BI Sampling error, sampling time exceeded
The parameter AFEH is set if the bit ”sampling time overflow”
(message 16, byte 0, bit 5) is set. The set parameter does not
influence the processing in the function block. The bit ”sampling
time overflow” can be reset by switching off the power supply or
by transferring message number 15 once with the command AE
(change the parameters of a controller).
BFEH: Q, BI Module error
The parameter BFEH is set when the signal state of the watchdog
bit does not change within 1 second.
(Data block DB-B, data word 32, bit 15.)
If the function block operating an IP 244 is called at intervals
greater than 1 second, the correct evaluation of the watchdog bit
is no longer possible.
