Hello, We have a problem with CodeSys on a raspbery pi with an ADS1015 analog to I2C module. It can't find the I2C device on the i2c bus, it says No I2C Driver Found. When we use the RPI terminal we can find the I2C device and read it out. The i2c-1 bus is also accessible from codesys. The device address of the Analog to I2C module is 0x48. Can someone have a look what the problem is? i submitted the screenshots in the attachments. i also include the device description and library.

I took a look at the xml Is this even the right driver and where did you get it?

I detect a Bug of Codesys....NO WORK AUTOMATICALLY RESTARSLAVES. I explain the secuence: I have click in my project the option AUTOMATICALLY RESTARSLAVES In the moment start my Ipc, the network ethercat start correctly I disconnect the wire of my first slave and later connect again the wire..(see the screen Bug Codesys restart slave1) NO work the restart automatic slaves...and is not possible execute of FB MC_REset beacuause appear this error (see the screen Bug Codesys restart slave2) The only way for resolver this problem is execute the FB SMC3ReinitDrive I replay the same with PLC BECKHOFF in Twincat3 and I havent this problem...In the moment connect the wire again in the slave the comunication of ehterCat restart and the slave comunication again with out problem

Hello Barton, I try to log the changes in Numpad (upon Ok button pressed) that an Element name/Element text variable is changed from so to so. How to get the Element name (or text fields Text Variable) from where the Numpad is called? Numpad is Invoked from Inputconfiguration->onMouseDown->Write a variable. Thanks

yes i took the library from another forum: https://forge.codesys.com/forge/talk/Runtime/thread/f1400b71b6/, it is made for the ads1115 but the ads1015 is almost the same device with same adresses i only changed the divide value of the analog value, because thats the only difference between the ads1115 and ads1015.

Is it possible under CODESYS V3.5 SP18, to connect a split (german Leitungsverzweigung) with an existing block (e.g. AND-module)? Or to connect the output of an existing block to the input of an existing block (e.g. OR-block)? Any ideas? P.S.: Sorry for the german title, I do not know how modify the title.

Note: if you do not get any values. Check the correct wiring again. The board seems to be running and you have no error.

Ok, this is a test programme with ADS1115. It is currently configured for the TCA9548 muxboard. If you want to run the ADS1115 single, then change the settings to the default values: ‘Is Multiplex:’ False ‘Stage mux channel numbers:’ [0,0,0,0,0,0,0,0,0] It is also important that the libraries are installed correctly here. But should be in this project

thank you, i tried your library and device description but i don't get analog values. Do i something wrong? i also got an library error at the I2C_BASE functionblock the calcCycleTime gave an variable size error, so i added thet conversion from ULINT_TO_UDINT.

Ist es unter dem FUP-Editor von CODESYS V3.5 SP18 möglich, eine Leitungsverzweigung mit einem existierenden Block (z.B. AND-Glied) zu verbinden? Oder den Ausgang eines existierenden Blocks mit dem Eingang eines existierenden Blocks (z.B. OR-Block) zu verbinden? Gibt es dazu Vorschläge?

Okay i will try. I tried already the different settings. The CodeSys version i use, is CodeSys 3.5 SP20 Patch 3. The device which i use is CodeSys Control For Raspberry PI 64 SL version 4.13.0.0. The wiring should be okay because i'm using the Edatec ED-CM4IND-1432-4C(EU).

The voltage what i want to measure is 3.286v. I can check the voltage through terminal, see screenshots.

Hi, Communication with the ADS1115 is actually simple. 1. write config 2. write address pointer 3. read conversation register The ADS1115 works like a multiplexer. This means that you do this individually for each channel that you want to read. e.g: Channel 1: write config > write address pointer > read conversation register Channel 2: write config > write address pointer > read conversation register Channel 3: write config > write address pointer > read conversation register Channel 4: write config > write address pointer > read conversation register then you start again from the beginning You can also omit individual channels or read only one. It doesn't matter. I have written the driver so that I can also use it on the TCA9548. The driver is from Stefan Dreyer. In your case, the driver works and communication with the ADS1115 is running. As you can see, the cfgWrong:=FALSE If you could not write or read data, cfgWrong:=TRUE; This means that either something is wrong with your ADS1115 or you have connected something incorrectly. Question: what voltage do you want to measure?

I tested your project but with same results i am still not seeing analog values. I also included the library list, the mainprogram.

After many tests i see that problem comes when serial communication established for modbus rtu. If the slave device not connected we don't see the exception. If the slave device connected at serial port then we have exception about 1 hour after startup and every 10 or 15 minutes. Any suggestion?

Ok, with debug you suppress the errors, but that doesn't help you any further. You can find information about the missing drivers here https://forge.codesys.com/forge/talk/Runtime/thread/8981ce928a/ and here https://github.com/stefandreyer/I2C-Multiplex I'll have to have another look at which library you need. But you can easily find out. Create a completely empty project and insert the TCA9548. You don't need the board. Then look in the library and resolve all conflicts If you can compile the project without errors, delete the TCA9548 and insert the ADS1115. The driver should then also run. Small bonus: with the TCA9548 you can expand your network as you wish and use identical sensors multiple times

okay, the weird thing is the driver is only continuous running when i enable debug output. if debug is not enabled it's continuous switching from running to not running. i will check again and download the libraries Which versions of libraries do you use, can you send a screenshot?

your driver is not running. All libraries must be present first! Then you can try the following. Delete the ADS1115 and the I2C_maseter from the device tree. Create everything again.

You are also missing the libraries. No library should be grayed out or highlighted in blue

Post by ellocco on XOR with four Inputs with OR-, NON- and AND-Operators
CODESYS Forge
talk
(Post)
My topic is more of academic nature, I would like to implement an XOR-operation with four inputs on my own (without the predefined XOR-operator) in a function block diagram (FBD). I have two proposals. One works fine and the other one is just an idea, but I do not know, if it is possible to code it in CODESYS V3.5 SP18 in form of a FBD. Here the one that works: And here an idea, which I have not managed to code it as an FBD: Any ideas? Is the 2nd diagram a correct interpretation of the coding task? And is there a way to implement it in form of an FBD in CODESYS V3.5 SP18? Followup (08-Nov-2024): Also in the current version of CODESYS (V3.5SP20Patch3) I have not managed to connect the existing blocks. In the alternative SPS-IDE PLCnext Engineer it is possible.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
