If the specified PPID is not found in the library, S7F6 has the following special

If the Equipment receives S7F6 and cannot store the Process Program in its library,
the CEID BadDownload is signalled, with PPChangeName set to the PPID of the

found" form, if the S7F6 message is not in the expected format, or if an error is
detected in PPBODY (for example, a parameter out of range).
