13.3.2.5 Defining signals (procedure)
Edge Gateway | NIOT-E-TPI51-EN-RE (Connect)
DOC170502UM07EN | Revision 7 | English | 2019-07 | Released | Public
Ø Enter a name for each IO item in the column Tag using the characters
A‑Z, a‑z, 0‑9 and _ (underscore) only.
Ê The name (Tag) is used for the signal name to address the data.
Ø In the column Description you can enter a text (e.g. temperature
sensor) which helps you describe the use of the data.
Ê This description is used only if you print the signal list.
Ø Repeat steps 1‑3 until all required IO items (assemblies) are inserted
into the „IO Item" list.
ð The EtherNet/IP configuration is prepared.
Ø To save the EtherNet/IP configuration in the Edge Gateway, click
Project> Save.
ð The EtherNet/IP configuration in the Edge Gateway is saved, but not
active yet
Ø To activate the EtherNet/IP configuration, you have to click
Reconfigure in the fieldbus node as soon as you have finished the
EtherNet/IP configuration.
In the next step define the signal names as described in section Defining
signals (procedure) [} page 198].
Each IO item (assembly) contains one or more bytes for input or output
data. To enable the fieldbus node to access the input or output data, you
have to select a signal at the fieldbus node. You can use the predefined
signal name or define your own signal name.
The upper table (IO item) shows the IO item (assembly) for which you can
define signals on this page. For defining signals, use the lower table
(Signals).
Each IO item (assembly) already has a predefined signal. The predefined
signal comprises and addresses the entire IO item (assembly). If you want
to access a „part" of the IO item, you can define a new signal for this
purpose.
Example 1: The IO item contains 16 bytes. If you want to access each
single byte, define 16 signals of data type byte each.
Example 2: The IO item contains 2 bytes that correspond to 16 digital input
or outputs. If you want to access each single bit, define 16 signals of data
type bit each.
