An error condition exists in FB 45 whenever the "Error" variable is enabled on a channel. If
this is the case, the exact cause of the error can be determined from variable "error_MOBY",
"error_FB" or "error_BUS".

Classification of error messages
Error variable
This error is reported by the communications module or reader.
There are two main reasons for this:
Errors have occurred in communication between the communications
•
module and the reader or between the reader and the transponder.
The CM cannot process the command.
•
Error_MOBY is indicated on the CM by the ERR LED with the corresponding
flashing pattern.
This error is signaled by FB 45.
Main cause
There is a parameter error in "Params_DB" or "command_DB".
•
The transport layer of PROFIBUS or PROFINET is signaling an error. A
PROFIBUS tracer and a PROFIBUS device (BT 200; order No. 6ES7181-
0AA00-0AA0) or a diagnostics repeater (order no. 6ES7972-0A801-0XA1) are
invaluable tools for accurate troubleshooting. The PROFIBUS system
diagnostics can provide further information about the cause of the error. The
error shown here is reported by the SFB 52/53 system function in the RET_VAL
parameter. For a detailed description of the RET_VAL parameter, please refer to
the SIMATIC S7 system manuals (see System software for S7-300/400).
