PiXtend eIO Hardware Manual
5.6.1.PiXtend V2 -L- as Master
The structure described here is suitable as a test setup in the office or laboratory area and
can only be seen as an example. A real construction in the industrial environment, for
example, has very different requirements and must be designed accordingly. All important
information can be found in the chapter
Technical Data & Connection Notes
But let's start with the test setup!
We use the following components:
•
1x PiXtend V2 -L- ePLC Pro (QS item: 622)
•
1x PiXtend eIO Digital One Pro (QS item: 801)
•
1x PiXtend eIO Analog One Pro (QS item: 811)
•
approx. 1-2 meters control cable with 2x or 3x 0.2 mm² / 0.25 mm²
•
approx. 3 meters of stranded wire - red - (1x 0.75 mm²)
•
approx. 3 meters of stranded wire - black or blue - (1x 0.75 mm²)
•
Laboratory power supply with setting to 24 V, min. 1 A
We assume here that all devices are configured to factory settings. You will find the
settings for PiXtend eIO in this document starting on page 11 and for PiXtend V2 -L- in the
hardware manual in the
of our
Note!
Make sure that all the devices listed are disconnected from the supply
voltage before wiring and further work is started.
All three devices are powered by a common power supply. We connect each 24 V and
GND directly from the power supply or a common terminal block to the devices. We do not
recommend further “looping” of the supply - from one device to the next (details on supply
in the chapter
Now the bus lines can be connected. Either with 2- or 3-pin cable. The cable is split into
two parts so that we can connect one line between the master and the first slave and
another between the two slaves.
