Control logic that supports the Trigger/Acknowledge handling must be
implemented in PLC from which process values shall be retrieved.
The SDL provides ready made control logic as control module types for the AC
800M controller. These libraries are distributed on the 800xA distribution media. By
default the following control logic softwares are included:
• SDL_DataExchangeLib for AC 800M.
For other types of PLCs the Trigger/Acknowledge handling has to be
implemented according to the section Data Exchange Protocol on page 319.
An .afw file containing a library for AC 800M controller implementing the data
exchange protocol is available in 800xA distribution media. After import it is
placed in the Library Structure as the sub object of SDL_DataExchangeLib
Library, under Library Collection object.
