ISaGRAF IEC61131 C Tools
The ISaGRAF C language application program interface provides the following functions.
Refer to the ISaGRAF C Tools Reference and User Manual for details.
 The getSFTranslation function returns an entry from the store and forward translation
table. The entry consists of two port and station address pairs.
 The setSFTranslation function writes an entry into the store and forward translation
table. The entry consists of two port and station address pairs. The function checks for
invalid translations; if the translation is not valid it is not stored. The function returns a
status code indicating success or an error if the translation is not valid. A translation is
cleared from the table by writing a translation with both stations set to
DISABLED_STATION (65535).
 The clearSFTranslationTable function clears all entries in the translation table. A
cleared entry has the port set to 0 (com1) and the station set to DISABLED_STATION
(65535).
 The checkSFTranslationTable function checks the translation table for invalid entries. It
returns a status structure indicating if the table is valid and the location and type of the
first error if it is not valid.
