Error transmitting the data record
The module always checks all values of the transmitted data record. The module applies the
values from the data record only when all values have been transmitted without errors.
The WRREC instruction for writing data records returns the appropriate error codes if there
are errors in the STATUS parameter.
The following table shows the module-specific error codes and their meaning for parameter
data record 128.
