3.2.1. INDIVIDUAL OUTPUTS
Figure 3.4 shows an ETS example of a channel parameterization: channel A is
parameterized as “individual outputs”, output 1 and 2.
Figure 3.4. Channel A configured as individual outputs
Once the output is enabled, in the topology window of ETS will automatically appear the following
communication objects (1-bit each):
[OX] ON/OFF
: allows activating (ON) or deactivating (OFF) the corresponding output,
through sending the value "1" or "0", depending on the parameterized output type.
[OX] Status
: shows the current status of the output (activated or deactivated).
[OX] Block
: allows blocking/unblocking the output (disable/enable its control) by sending
the values "1" or "0" to the object, respectively.
Note:
Only the Alarm function has higher priority than the block function; i.e., if during the
block an alarm signal arrives, the corresponding output will be placed as indicated by the
alarm. When the alarm is deactivated, the output returns to the block status.
The first thing that must be parameterized is the type of each output of the channel:
Normally open:
the output will be activated (ON) when its relay closes. The output will be
deactivated (OFF) when its relay opens.
Normally closed:
the output will be activated (ON) when its relay opens. The output will
be deactivated (OFF) when its relay closes.
