4 Detailed Functions Description
The channel may additionally be blocked via
“Jamming”
CO it
“Jamming usage”
is set to be used. It
can be blocked if
“Jamming”
CO receives “TRUE” (parameter set to “If '1'”) or blocked if
“Jamming”
CO receives “FALSE” (parameter set to “If '0'”).
It's also possible to limit the time extension for which the channel remains blocked. This is is done the
setting
“Use Time Limited Jamming?”
to “Yes” and by selecting the duration in the parameter
“Duration”
.
g) Channel status after overriding operations
Manual operation, priority and jamming are considered overriding operations since they impose a certain
output status. The status the output takes when any of those overriding operations is ended can be defined
in the parameters
“Status after [Manual Mode operation/Priority operation/jamming]”
. Setting this
parameter to “Maintain” causes the channel to keep that status that was imposed by the overriding
operation; if the parameter is set to “Previous status”, when the overriding operation terminates the
channel's output is set to its status just before the time the overriding operation starts; if parameter is set to
“Invert”, when the overriding operation ends the output status inverts the output imposed by the
overriding operation; setting the parameter to “On” causes the channel to go to “On” status when the
overriding operation terminates; setting the parameter to “Off” causes the channel to go to “Off” status
when the overriding operation terminates; by chosing “Theoretical status without
[manual/priority/jamming]” causes the channel's output to go to the status it would be in case the
overriding operation didn't occur.
In Figure 6 is shown the time diagram of a possible scenario in which the device is configured with
“Jamming usage”
to “If '1'”,
“Use Time Limited Jamming?”
set to “Yes”,
“Duration”
set to
T_jamming
;
“''On/Off'' Com.Obj. Function”
set to “Delayed On” with
“On Delay amount”
of
T_d
. In
this scenario, the
“Jamming”
CO takes a message that triggers the beginning of the channel's jamming
for a duration of
T_jamming
; meanwhile
“On / Off”
CO takes “On” message, once the jamming
period expired the “On” message is taken in consideration and the “On Delay” is initiated.
If one operation is already in course that operation will not be blocked, this means, for
instance, if a “Delayed On” operation is in course when a jamming/priority/Manual mode
message is received, that “Delayed On” operation will continue and the channel will switch.
