Programming with STEP 7
Manual, 05/2010, A5E02789666-01 389
The error texts generated for standard errors are arranged as follows:
Error Number
(decimal)
Error-OB Affected Error Code in the OB
from to from to
1 86 OB 72 B#16#1 B#16#56
162 163 OB 70 B#16#A2 B#16#A3
193 194 OB 72 B#16#C1 B#16#C2
224 OB 73 B#16#E0
289 307 OB 81 B#16#21 B#16#33
513 540 OB 82
849 900 OB 83 B#16#51 B#16#84
1537 1540 OB 86
1729 1736 OB 86 B#16#C1 B#16#C8
1738 1742 OB 86 B#16#CA B#16#CE
1743 1744 OB 86
Error numbers greater than 12288 refer to channel errors. If you view the error number in
hexadecimal representation, you can calculate the channel type and recognize the error bit. For an
exact description, refer to the respective module help or channel help text.
Example:
12288 = W#16#3000 -> high byte 0x30 - 0x10 = channel type 0x20 (CP interface);
low byte 0x00, means error bit 0
32774 = W#16#8006 -> high byte 0x80 - 0x10 = channel type 0x70 (digital input);
low byte 0x06, means error bit 6
Diagnostic support
To display diagnostic events on an HMI device graphically, you can create a PROFIBUS DP DB
(default DB 125) or a PROFINET IO DB (default DB 126). You can create a data block to support
the CPU Web server (default DB 127) to display the module status in the Web server of the CPU.
