b) "On/Off" Communication Object Functions
The COs that are related with this functionality are:
[input] "On / Off": controls the output's status according to the selection in "''On/Off''
Com.Obj. Function";
The function executed when a message arrives to the "On / Off" CO can be defined with the
parameter "''On/Off'' Com.Obj. Function". When set to its default value "On/Off", when an "On"
message is received the output switches to the On position; if an "Off" message is received the output
switches to its Off position. Three delayed modes are available: "Delayed On", "Delayed Off" and
"Delayed On/Off"; and two timer modes: "Timer On" and "Timer Off". If the parameter is set to
"Delayed On (immediate Off)" upon arrival of "On" message in the "On / Off" CO the output status
will switch to its On position just after the time defined in "On Delay amount", however an "Off"
message will switch the output to its Off position immediately; for "Delayed Off (immediate On)" the
behavior is analogous; when the parameter is set to "Delayed On/Off" both On and Off output switch are
delayed. The delay is interrupted by the opposite message and restarted if the same message is sent (last
message overrides previous).
If the parameter is set to one of the "Timer" functionalities, its operation will be similar to the description
in 4.2.1a when the parameters "Allow timer interruption with Stop?" is set to "Yes", "Consecutive
presses multiply time (within 10s)?" is set to "No", "Allow timer reset?" set to "Yes" and without pre-
warning.
c) Logic functions
The COs related with logic functions are:
[input] "Logic - [FUNCTION]": the input CO of the logic function;
It's possible to use one more input CO in combination with the "On / Off" CO to control the output
status. That is done by selecting the desired operation from the "Logic input function" parameter.
Chosing "Autorize ''On/Off'' Com.Obj." will allow the operation of "On /Off" CO just if "Logic –
Authorize" CO is "True", otherwise sending messages to "On /Off" CO has no effect; if the
parameter is set to "Inverted Autorize ''On/Off'' Com.Obj." the operation of "On /Off" CO is enabled if
"Logic – Inv. Authorize" CO is "False".
