Post by julianramirez on ModbusFB write update ^{CODESYS Forge talk (Post)}
Hello everyone, I am testing the ModbusFB library tcp server and so far I am able to create holding registers successfully, however, I am trying to identify after each write which registers got updated (i.e. function code, write value). I can even see the var udiNumWriteRequests, which increases with every write. I noticed that there is logging with the LogStatusInfo method. After I call it I am able to read in the console stuff that I want. Nevertheless, this is only available at the logs and is not easy to decode because it consists on several messages, I would like to know if there is a way for me to retrieve this information from the function itself with pointers or if there is any way to copy the logs messages (assuming that I can filter them with the LoggingOptions to only show what I need) inside the runtime code and not in the console. Thanks for your help :)

Post by andrax on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
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?

Post by ofey on Modbus TCP communication ^{CODESYS Forge talk (Post)}
Hi! I tried setting up the PLC I'm working with (Beijer GN-9373) to connect to a modbus master running on a laptop. I have an ethernet connection (via USB-C to ethernet) between the laptop and the controller. I have tried following tutorial on how to set this up. I have added an ethernet device with the IP-address of the PLC. Further I added a ModbusTCP_Slave_Device with default settings. I get the error "Failed to open TCP Port: 1" when I try to go online with the PLC. Earlier I tested the exact same set up with the soft PLC from codesys. I can then read/write values correctly with the Modbus master i have running on the laptop. Hope anybody can help me with this, thanks in advance!

Post by totorovic on CSVReaderInit returns error : INVALID_HANDLE ^{CODESYS Forge talk (Post)}
We changed the path where the CSV file is. From intern memory of the IPC to a USB key. We still have this error 'INVALID_HANDLE'. We must restart the Codesys runtime to clear it. That is a big problem for us because machine is in production. @eschwellinger What do you mean by "this is a security issue not to read/write in the plc allowed path"

Post by stuartjr on Disabling forcing of specific variables ^{CODESYS Forge talk (Post)}
I also thought that if I had logic writing a value to this variable, then it would override the force anyway, since I thought that the force request was only applied at the beginning and end of the PLC scan. But this doesn't seem to be the case, the force persists throughout the logic regardless of what I write to the variable with logic
