You can use FB_WritePersistentData to save the persistent date when you want.

Andere Projekte / other Projects / Weather data via raspberry pi and node-red

« am: 26. Februar 2019, 09:11:30 »

Because of all the problems with the weather blocks: not supported, no free accounts, especially change of data, or only json...
I decided it would be much easier to use node-red to get the weather data and to send it to the PLC via spidercontrol web variables.
There are several nodes for different weather providers (openweathermap, darksky...)
Attached an example node-red flow where I get the weather data from DarkSky and send it to my Phoenix Contact plc. I keep using the Oscat_Yahoo struct inside the PLC (set as PDD), so in the plc I only had to disable the Yahoo weather function block call.

I wanted to have an easy, fast and secure acces to the webvisit visualisation at home from my mobile.
I dit it with the aid of apache reverse proxy running on a raspberry pi.

Modulentwicklung / Energy datalogger emoncms.org

« am: 25. September 2018, 21:04:19 »

Hi, I found the DLOG blocks very usefull. I made one for emoncms.org, a datalogging and visualisation system (including app) for energy consumption from openenergymonitor.org. Unfortunatelly not free any more to use their servers, but you can install the software on a raspberry pi.
I also made a UDINT logger block. Exports from pcworx are included.

Modulentwicklung / Re: MQTT - Datenaustauschprotokoll - Baustein gesucht

« am: 30. November 2017, 22:14:11 »

I had a quick look at the protocol description, it does not seem to difficult to implement, one just needs time... On the other hand, how data is send is not defined, so we should find a way how to implement this generic format in the plc.

Modulentwicklung / Module Development / Development source code management of oscat

« am: 28. September 2017, 20:53:46 »

Can any body of the developpers explain how is the development of the source code organised for the different platforms?
For each FB, there is code that is identical, some have minor changes, some is completely different. How is this maintained? Is it a pure manual job, is there some kind of sourc code control system involved? Is there some conversion tool?
How is the documentation done?
I am interessed because I face the same problem: I need to convert/develop a specific library for pcworx and twincat.

Any help is apreciated

Again, Yahoo Weather is not working correct any more. Since the last modification, the request was split in 2 parts. Since 1 september, part 2 is about 4500 bytes, giving a network buffer overflow.
I've split it up in 3 parts (pcworx export attached)
Teil 1: http://query.yahooapis.com/v1/public/yql?q=select%20units,wind,atmosphere,astronomy,location%20from%20weather.forecast%20where%20woeid=551801%20and%20u=%27c%27
Teil 2: http://query.yahooapis.com/v1/public/yql?q=select%20item.lat,item.long,item.condition%20from%20weather.forecast%20where%20woeid=551801%20and%20u=%27c%
Teil 3: http://query.yahooapis.com/v1/public/yql?q=select%20item.forecast%20from%20weather.forecast%20where%20woeid=551801%20and%20u=%27c%27

Bestehende Module / Existing Modules / Setup Dutch translations and Belgian hollidays

« am: 26. Juni 2016, 21:55:54 »

I've added Dutch translations for days and months. Also Belgian official hollidays in Dutch, French and German.
Attatched the export files for pcworx.
Following types must be changed to ARRAY [1..4]: oscat_MONTHS, oscat_MONTHS3, oscat_WEEKDAYS, oscat_WEEKDAYS2   
oscat_LOCATION_ELEMENTS   : ARRAY [1..7] OF INT;

oscat.lib fuer Step 7 / Re: Fehler in CALENDAR_CALC und DST / Error in CALENDAR_CALC and DST

« am: 05. Juni 2016, 21:52:14 »

The night calculation is true for one scan on startup of the plc.
The night calculation must be moved after the 'run once per day' calculations

Off Topic Diskussionen / Re: Quo Vadis, OSCAT?

« am: 18. Mai 2016, 20:31:44 »

I agree that a new release of the netlib would be a good sign.
"wir als kleines team": it would be good to have this team described on the 'impressum'
Also an idea: how can somebody cooperate/share improvements: the best would be that there is a procedure describing how this can be done.

For the rest: nothing but thanks for the massive work that oscat has done to create this library!

oscat.lib fuer PC WorX/MULTIPROG / Re: Date_Add

« am: 30. Januar 2014, 11:22:52 »

Mit negative Täge geht's nicht auf PcWorx, da DATE_ADD UDINT ist (kein DATE datatyp)
Hier meine Lösung:

day := D + W * 7;
IF day >= 0 THEN
    DATE_ADD := IDATE + INT_TO_UDINT(day) * UDINT#86400;
ELSE
    DATE_ADD := IDATE - INT_TO_UDINT(ABS(day)) * UDINT#86400;
END_IF;
yr := Y + YEAR_OF_DATE(DATE_ADD);
mo := M + MONTH_OF_DATE(DATE_ADD);
dm := DAY_OF_MONTH(DATE_ADD);
WHILE mo > 12 DO
   mo := mo - 12;
   yr := yr + 1;
END_WHILE;
WHILE mo < 1 DO
   mo := mo + 12;
   yr := yr - 1;
END_WHILE;
DATE_ADD := SET_DATE(yr, mo, dm);
