Error Information for HMI FBs

Introduction
This chapter describes error information for HMI FBs, including when error
information occurs and how the cause of the error can be removed.
The FBs use the error code (return value "RETVAL" parameter) to supply
information about the errors and the status of HMI functions or the integrated HMI
module.
On the "HMI API" FB, you receive more detailed information on the error code
involved by means of the "ADDINFO" parameter.
In addition to the error codes listed here, those of SFC 58, SFC 59, SFC 83, and
SFC 84 are also relevant. These SFCs are called internally by the HMI FBs. The
SFC error codes are output without modification using the "RETVAL" parameter.
Additional information on the error codes for these SFCs can be obtained in the
STEP 7 Online Help.
