Error Messages of the CP 243-1 IT
This section lists the error messages of the CP 243-1 which are of primary impor-
tance to the user. All other error messages indicate special internal errors of the
CP 243-1 IT. If such error messages occur, please contact your service hotline.
Caution
The module must be turned off and on again when a module error/system error oc-
curs.
The CP 243-1 IT uses two different routines to report errors.
•
As return value of a subprogram
Errors are reported here with the return value "Error." This parameter can be
type BYTE or type WORD depending on which subprogram is involved.
•
Error codes returned via the SM memory area of the S7-200 CPU
Which SM memory area is being used currently depends on the position where
your CP 243-1 IT is connected on the S7-200 system (see Table 5). Depending
on the type of error, the following bytes are used for the error message in the
current SM area of your CP 243-1 IT.
−
Global errors and general messages are transferred at byte offset 20 and
21. They are interpreted as a word (SMW). The error or message codes
transmitted here are deleted again after a maximum of 60 seconds. This rou-
tine prevents outdated error or message codes from blocking these two
bytes for a longer period of time.
−
Channel-specific errors are transferred in the following bytes based on the
related S7 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 29
For channel 4
Byte offset 30
