8.6 Basic Application Functions
Station initialization
(station-specific parameter, mark “X” if function is used)
Cyclic data transmission
(station-specific parameter, mark “X” if function is only used in the standard direction,
“R” if only used in the reverse direction, and”B” if used in both directions)
Read procedure
(station-specific parameter, mark “X” if function is only used in the standard direction,
“R” if only used in the reverse direction, and “B” if used in both directions)
Spontaneous transmission
(station-specific parameter, mark “X” if function is only used in the standard direction,
“R” if only used in the reverse direction, and “B” if used in both directions)
Double transmission of information objects with cause of transmission spontaneous
(station-specific parameter, mark each information type “X” where both a Type ID without
time and corresponding Type ID with time are issued in response to a single spontaneous
change of a monitored object)
The following type identifications may be transmitted in succession caused by a single
status change of an information object. The particular information object addresses for
which double transmission is enabled are defined in a project-specific list.
