The next three columns provide the dynamic information about the signal, i.e. its value and cause
of transmission. At the same time, they are also used by the user to specify the value (and cause
of transmission) with which the signals will be simulated. These columns are the following:
– Cause of transmission:
This column contains the cause of transmission with which the signal is sent. The possible val-
ues for each specific signal are listed in a drop list: SPONT (spontaneous), PERIOD (periodic),
BACKG (background), REQ (required), INTERROG (interrogated), RET_REM (returned by re-
mote command), RET_LOC (returned by local command), ACT (activation), ACT_CON (acti-
vation confirmation), DEACT (deactivation), DEACT_CON (deactivation confirmation) and AC-
T_TERM (activation termination).
The column includes a drop list with gray background at the bottom. If one of the options of
this gray drop list is selected, all drop lists in the column containing the same option will change
their selected option to the one specified at the bottom. (Fig. 43).

– Confirm:
For process commands (outputs; SCO, DCO, RCO, ASO, DSO, FSO and BSO), this column
includes the confirmation field of the cause of transmission. The two possible values are includ-
ed in a drop list: POS (positive confirmation) and NEG (negative confirmation). The column pos-
sesses another gray drop list at the bottom, whose function is the same described for the pre-
vious column.
