implemented by the customer - in their own responsibility - in other programming languages and systems. Unlike previous Qube Solutions products, the PiXtend eIO devices are delivered exclusively as finished devices that are ready to use and do not require final assembly by the customer. The PiXtend eIO devices are designed for dry indoor environments - protection class IP20 (Pro), IP00 (Basic). Operation outdoors ...

2.3. Technical Condition Every PiXtend eIO device, regardless of its variant, is delivered with a defined configuration: PiXtend eIO Digital One • All digital inputs are configured for the 24 V range (no jumper plugged in) • Address: 1, baud rate: 19,200 baud, parity bit: even, stop bits: 1 (8E1) • Termination inactive, Mode / Protocol: Modbus RTU • The microcontroller firmware always complies with the lat ...

2.4. Certificates This product has been designed and manufactured in accordance with applicable european directives and is therefore marked with the CE sign. The intended use is described in this document. A safety data sheet is supplied with each product in paper form (multilingual). Warning: Changes and modifications to the product, as well as a non-compliance with the information contained in the manuals and sa ...

3. Basic Knowledge In this chapter basic knowledge is taught, which is needed for the use of PiXtend eIO. The sub-areas Power Supply (page 16), Bus Topology & Wiring (page 19) & Bus Lines (page 22) are described in detail. Especially if you have no or only little experience with RS485 bus systems, the following information is important for the safe and reliable operation of PiXtend eIO devices. www.pixtend.com ...

3.1. Power Supply All PiXtend eIO devices are operated with a nominal supply voltage of 24 V (DC voltage). The exact specifications and connection instructions for a suitable power supply can be found in chapters 5.4 Connect Supply Voltage and 6 Technical Data & Connection Notes. This is about the topology of powering several eIO devices in a RS485 bus / network. Figure 1 shows the correct wiring or power supply t ...

If the modules are spatially separated in a network or it is necessary to use several power supplies for the entirety of the bus participants for other reasons, the ground (GND) of all power supplies must be connected to each other at a central ground point via a suitable cable - equipotential bonding. In the following figure 2 we show you typical wiring errors with regard to the power supply of the modules. At fi ...

Similarly, the potential equalization between several power supplies (GND connection between all power supplies, which supply devices on the bus) must not be omitted! Summary: • Make the conductor cross section for the supply connections larger in case of doubt (we recommend 0.75 or 1.00 mm²) • Separate wiring of each module from the supply point / ground point • Supply of the digital outputs also with two ...

3.2. Bus Topology & Wiring The PiXtend eIO devices communicate via a 2-wire1 RS485 network. This must be done as a line structure / bus structure. The topology (see Fig. 3) must be adhered to in order to ensure error-free bus operation - even over longer transmission distances and baud rates. In order to be able to implement the bus structure in the best possible way, PiXtend eIO devices offer each of the RS485 si ...

There are different topologies for networks. However, star, tree, ring and mesh networks are not suitable for RS485 and therefore not for PiXtend eIO. RS485 is always set up as a line or in a bus structure. All participants within a PiXtend eIO network need the same ground reference. Without a common ground, there can be transmission problems and, in the worst case, a defect in the RS485 drivers. In case of doubt, ...
