#LOXONE 1WIRE PC#

The ECO120 controller allows the integration of all 1-Wire sensors to all controllers like PLC or PC systems without special knowledge about the 1-Wire protocol. All systems can access 1-Wire sensors and actuators via the intelligent interface (1-Wire Controller 100). a controller from Loxone, WAGO, Smart1, IP-Symcon. Whatever system you want to use, the ECO 120 - the intelligent system and programming interface for 1-Wire bus sensors and actuators is ready for it. Add an error-correction algorithm to your reading process so that you re-read if the result shows an error.ECO 120 1-Wire controller desktop device, the intelligent system interface for the desktop These use an active pull-up rather than the passive resistor pull-up.

use a dedicated 1-wire line driver instead of the Pi's built-in system. change the value of the resistor at the Pi end of the cableДў. Two approaches if it is less than perfect:ДЎ. So start with one and if it works then add more and try again.ДЄs I said, 5 sensors and 30 metres should be OK. It is noted that more sensors at the end of the line will impact performance. Leave unused wires disconnected - do not attach them to ground at either end.ДЈ0 metres and five sensors should be OK. So use one twisted pair for data and ground and a single wire from another pair for power. Line capacitance is just like adding a capacitor to a circuit, it slows down the rise in voltage as it charges (signal goes from low to high) and it slows down the fall in voltage as it discharges (signal goes from high to low) 1-wire signaling is heavily dependent on the voltages rising and falling within short periods of time. The increased capacitance far outweighs the value of reduced resistance.ДЈ. By using 6 wires when 3 would do, you are adding a very large amount of extra capacitance, which is a real killer for the 1-wire system. According to the manufacturer's notes all unused pairs should be left unconnected. Using untwisted pairs of twisted pairs effectively means you are carrying the signal over an untwisted cable.Дў. The twisting of the pair increases it's immunity to noise (external electro-magnetic radiation). Twisted pairs should be both parts of the signal-carrying pair. Does anyone have an opinion on whether this would be helpful or harmful?I would strongly suggest against that arrangement.ДЎ. YMMV.Д¬yEE wrote:I'm thinking it would be helpful to use a twisted pair (Brown/BrownWhite, etc.) for each 'wire' to the sensors, 3.3 V, Data, and Ground. Incorrectly telling someone that they cannot achieve what they want (when someone has already told them that they can do it) will raise people's hackles.Дisputing the evidence and claiming that it backs your position when it doesn't can also irritate people. The OP want's to extend his single sensor 1 wire network to have a longer cable run, reading the article shows that this is easily within the 1 wire capabilities.

For them, keeping the 1-Wire short is a great idea (again, YMMV) (again, YMMV) If its trivial for you, great! Not all people are electrical engineers, nor experienced hobbyists.

and if you don't think so, just look around the net at all the questions about how to make it work and it goes up proportionally to the length of the bus 'wire'. but, I am amazed at the sheer number of people who have trouble making the 1-Wire 'bus' work at 'any' length!. If you read the article carefully you will notice that running a long 1-Wire is NOT trivial (again, YMMV) and making reliable is more easily said than done (again, YMMV). YMMV is the expression that comes to mind. Hi ame, I am utterly amazed at how argumentative everyone is here.

10m is trivial, 20m is easy, and longer runs are quite achievable. This is similar to the i2c bus length if you exceed about one meter then you will have intermittent problems due to capacitance issues and|or noise. MarkHaysHarris777 wrote:You really should not exceed about 1.5 meters tops.
