6.2 Error messages of the CP 243-1
The most important CP 243-1 error messages for the user are presented below. All
other error messages refer to specific internal CP 243-1 errors. Please consult the
Service Hotline if such an error message should occur.
Attention
In the event of a module error / system error, the module must be switched off and
on again.
Basically, the CP 243-1 has two mechanism for reporting an error:
• As a return value of a subroutine:
Errors are reported by the “Error” return value. Depending on the subroutine,
this parameter can be of the BYTE or WORD type.
• As an error code that is returned through the SM memory area of the S7-200
CPU:
Which SM memory area is currently in use depends on the position in which
your CP 243-1 is connected in the S7-200 system. Depending on the type of er-
ror, the following bytes in the current SM area of your CP 243-1 are used for er-
ror messages:
− Global errors are carried over in byte offset 20 and 21. They are to be inter-
preted as Word (SMW)
− Channel-specific errors are carried over in the following bytes, depending on
the associated channel:
Byte offset 25 for channel 0
Byte offset 26 for channel 1
Byte offset 27 for channel 2
Byte offset 28 for channel 3
Byte offset 39 for channel 4
Byte offset 20 for channel 5
Byte offset 31 for channel 6
Byte offset 32 for channel 7
− Command-specific errors are returned in the byte with offset 33.
The error codes of the individual errors and their meanings are listed in the follow-
ing tables. These tables also indicate by which mechanism the individual errors are
returned, which error code can occur for which subroutine, and which error is car-
ried over in which byte of the current SM memory. If error messages occur that are
not described in these tables, please consult the Service Hotline (see Chapter 7).
