5.2
An error condition exists in FC 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_FC" or "error_BUS".

Notice
When several error occur with chained commands, the "error variable" always indicates the
first error detected.

Classification of error messages
This error was reported by the MOBY-ASM / write/read device.
There are two main reasons for this:
Communication between ASM and write/read device or between write/read
•
device and MDS is faulty.
The ASM is unable to process the command.
•
Error_MOBY is indicated on the ASM on the ERR LED with an appropriate
flashing pattern.
This error is signaled by FC 45.
Main cause
There is a parameter error in "Params_DB" or "command_DB".
•
The transport layer of PROFIBUS is signaling an error. A PROFIBUS tracer and
a PROFIBUS tester (BT 200; Order No. 6ES7 181-0AA00-0AA0) is an
invaluable tool 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 SFC 58/59 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).
