3.3. CHANNELS
Channel screens will show for the first time as follows:
Figure 3.3. Configuration screen for Channels
It is possible to independently enable the parameters
Active Energy
,
Active Power
and
Power
Limit Monitoring
for each active channel.
Moreover, after enabling a certain channel, three new 1-bit communication objects will come up per
channel
: “[Cx] Reset”, “[Cx] Request” and “[Cx] Disable”. Note the distinction between the objects
“Global Request” / “Global Reset” (which affect all channels) and the objects “[Cx] Request” and
“[Cx] Reset” (which affect only a certain channel).
When the Energy Saver receives the value
“1” through the object “[Cx] Reset”, every
communication
object and variables related to estimations and average / total values of channel “x”
will be re-set to zero. Receiving the value
“0” will have no effect.
When the Energy Saver
receives the value “1” through the object “[Cx] Request”, it will report the
accumulate values
–since the last reset– for the energy consumption, its cost and the carbon
dioxide emissions related to channel “x”. These values are reported through the communication
objects
“[Cx] Total Energy”, “[Cx] Total Cost” and “[Cx] Total CO2 Emissions”, respectively, which
will automatically show up when enabling the corresponding option under ETS. In addition, if the
option
“Reset after request” has been enabled under the General screen, whenever a “1” is
received through the object
“[Cx] Request”, a reset process similar to the one described above will
also take place. Note that the three total objects are not intended to be read in an independent
manner; their values will only be sent to the bus all together, as a response to the “[Cx] Request”
object.
The object
“[Cx] Disable” allows enabling (when the value “1” is sent) or disabling (when the value
“0” is sent) power measures for channel x. When measuring has been disabled, cyclic sendings
(those parameterizable from the General screen) as well as the sending of instant values (instant
power and peak power) and estimated values (energy and cost) do no longer take place.
