5.4. Definition of Channels
Up to 8 channels (real + virtual) can be defined for an e.bloxx. They define how the signals at the in- and outputs of the
e.bloxx will be processed. The value of every channel can be read out via the fieldbus. The channels are defined in the
Variable Settings Table in the Configuration Software ICP 100.
The Variable Settings Table is displayed on the corresponding register card in the Configuration Software ICP 100.

5.1. - Example for Variable Settings Table
Here all 8 possible channels will be listed. To define a new channel just click on a free line in the table or to change the
type of channel click on the first column
Type
in the corresponding line. In both cases a dialog box will be opened where
the type of the new channel has to be selected. There are 5 different types of channels:
- Digital Input Channel: Used to record digital status signals, measure frequency or count digital signals. In the column
Type of Measurement
it is possible to select the measurement function (state recording,
counter or frequency measurement, refer to chapter 4).
- Digital Output Channel: Used for digital status signals, process out or PWM. In the column
Type of Measurement
it is
possible to select the measurement function (state, process out, PWM).
- Arithmetic Channel:
With this channel it is possible to perform calculations with the actual values of other channels
and with constant values. The results of the calculations are assigned to the arithmetic
channel and so arithmetic channels can also be used by other arithmetic channels for
calculations.
- Alarm Channel:
An Alarm Channel can be used to monitor another channel and to generate an alarm
message if one of up to 4 definable thresholds are exceeded. The alarm messages can be
read via bus.
- Setpoint Channel:
The value of this channel can be set via bus. This way it is possible to set a value via bus
which can be used by an arithmetic channel for further processing, e.g. to set a factor for
measurement by the user.
The settings for all defined channels will be displayed in the corresponding column of the channels. To change these
settings click on the corresponding field in the Variable Settings Table.
