2. Important Information
This chapter contains information about the subject to change topic, the intended use, the
technical condition of the described product, the disclaimer, the safet notices and where
to get help.
2.1. Su ject to Change
The compan Qube Solutions GmbH reserves the right to revise or amend this
documentation in whole or in part if this serves the technical progress or if existing
software components have to be changed or new ones have been created. The user will
alwa s find the latest version of this documentation at http s ://www.pixtend. de /downloads/ .
2.2. Intended Use
PiXtend V2 -L- is used in combination with the single-board computer "Raspberr Pi"
(Raspberr Pi Foundation, UK registered charit 1129409), which is alread included in the
product (PiXtend V2 -L- ePLC Basic / Pro) or has to be bought b the customer as an
accessor (PiXtend V2 -L- Extension Board).
The PiXtend V2 -L- s stem fulfills the function of a programmable logic controller (PLC) or
an electrical measuring, control, regulating and laborator device. It can read and evaluate
sensors and control actuators. The logic programming of inputs and outputs can be done,
among other things, with the software "CODESYS V3" from the compan 3S Smart
Software Solutions GmbH. Qube Solutions also provides components for other
programming languages and s stems from the areas of IT and home automation that the
customer can use. Instructions and examples have been created b Qube Solutions for
this purpose.
The PiXtend V2 -L- devices are designed for dr indoor environments - protection classes
IP20 (ePLC Pro) and IP00 (Extension Board and ePLC Basic). Operation outside and in
humid/wet rooms is not permitted, except the PiXtend units are installed in a suitable
housing. The devices are not designed for hazardous areas or safet critical s stems /
installations.
PiXtend V2 -L- devices can be used equall in the industrial/commercial environment as in
educational facilities and in residential areas.
PiXtend V2 -L- offers the possibilit , under certain conditions, of switching hazardous
voltages. Work on dangerous voltages is onl permitted for qualified personnel (the
requirements ma differ from countr to countr ). If in doubt, the use of dangerous
voltages is prohibited.
Apart from this, PiXtend is suitable for all persons aged 14 and over who have read and
www.pixtend.com Copyri ht by Qube Solutions GmbH 9 / 146
PiXtend V2 -L- Hardware Manual
understood the safet data sheet and the manuals. Training facilities must be supervised
b qualified and authorized personnel. Power supplies and accessories used must be
approved for the countr in which the PiXtend V2 -L- s stem is to be installed and used.
2.3. Technical condition
PiXtend V2 -L- is supplied with a pre-defined configuration, independent of its model:
•“SPI_EN” switch activated → Communication between PiXtend & Raspberr Pi is
activated
•“PI_5V” switch activated → PiXtend & Raspberr Pi are supplied b the same
voltage regulator on PiXtend (input voltage 12 - 24 V DC). No separate power
suppl needs to be connected to the Raspberr Pi
•All digital inputs are configured for a 24 V range (no jumper is set)
•All analog inputs are configured for a 0..10 V range (no jumper is set)
•"CAN" / "AO" Jumper is set to "AO" → analog outputs active, CAN inactive
•RS485 "A" / "M" Jumper is set to "A" → automatic send/receive switching
•Termination resistors for RS485 and CAN are not set (no jumper)
•The microcontroller firmware is alwa s the latest version released b Qube
Solutions. The current version can be found on our homepage
The ePLC models include additional configurations:
ePLC Basic & Pro
•Contents of SD-Card
◦the content is stated in the order, e.g. "CODESYS Control Demo" or "PiXtend
Basic" (in the QS-Shop)
◦Our dealers alwa s receive and ship the SD card "CODESYS Control Demo"
ePLC Pro
•Housing → Stainless steel hood and DIN rail housing pre-assembled
If ou need a different version or a different hardware and software combination, please
