I am using a modbus RTU connection; however, even when I successfully connect to a Modbus slave application, the orange triangle does not go away. Any ideas?
I followed your process but can't enable the process manually just like you did at timestamp 31:41. Can you please let me know what could be the reason. The program is running smoothly with no error BTW.
@@brightersidehacks I have followed your steps but when I ran the code, xEnable was not getting True, even if I try manually. I could set the prepared value but the value was not being shifted to current value. I didn’t get any error too. Can I use the same code for a TBEN-S2-2COM-DXDP controller with a PC using Modbus TCP?
Brighterside, thank you for this very interesting tutorial. I have followed this and it seems my SysFileOpen function breaks if I try to write file to any directory on my disk. It seems that I have access to only current runtime PlcLogic folder. I use win10 with Codesys 3.5.20. I know I used to write to my win file system in older Codesys versions, and I found that this has been changed from 3.5.19. However, I have found on Codesys forum an instructions how to add entries under section of [SysFile] in some Codesys…User.cfg file. Unfortunately links are not valid anymore, Do you happen to know how folder like C:\Temp can be added, so SysFileOpen can create file in that folder also?
Hello my friend, thanks for you explanation with communication topics. Do you know something about fetch/write communication? I’ve had pre configured Codesys projects with communication with S7 Siemens DBs
Excellent example? Is this CODESYS project available for download? Also it would be good if you place links to equipment you used in the video description. For example, what type of raspberry pi, what is the exact model of this rs232 to ttl converter etc.
Great educational video. I do have a question regarding the soft PLC available on a PC. Maybe I am missing something, but why would I choose 32 bit runtime with Control Win V when my OS like most modern Windows versions are actually x64? Is there a specific reason why you choose Control Win V3 32 bit in this example?
There is absolutely no reason, you may choose whichever bit version you wish. My choice for 32 bit version was based on a certain library that i could not install on the 64 bit version, otherwise you shouldn't have any issues
Yes, if you want to use it in production, you need t buy a license. However, even without a licence, you can use it for development, every time you start the runtime, you will have a trial period of 2 hours for all field buses including OPC UA server
@@brightersidehacks Thanks for the info, but in that case, how to simulate this communication, are there any additioanl settings in the projects that needs to be done? Scan devices will not return real slaves because everything in on the same PC. I suppose some third party ECAt slave simulator is needed?
Thanks for providing the support. Using this implementation I could transfer data to localhost. But while I try to connect it to remote client (on other PC on same network), the client could not establish a connection. While I could do data transfer through modbus poll and and modbus slave, between my PC and the remote PC. What shall I do..
Make sure that the Computer has a IP address Reachable by your slave. also make sure that the port is free and not in use by any other service. Infact instead of setting the host address to 0.0.0.0, you could directly use your Computer Ip address
Thank you Man , Much appreciated. I just mange to Read API on A FESTO PLC . Would love to have more help in development as i have to read values every minute. But how do you get a single value from the entire header. How do you isolate it ?
@@brightersidehacks I recieve it like this at your example Below is an example for test. Which i manage to read it all. But how can i read only one line and get only the number 123.456 from the below content. Which other Command can i use to take the specific value. Example { "Binary1":True, "Binary2":False, "None":null, "Empty":""", "Float":123.456, "integer":234 } thanks in advance.
@@usernamekitkat Now what you need is to find a way to deserialise the json string to extract the data you want. There are some json libraries you can use for this
Hi Brighterside Tech, I have an issued in my application, i need to make a csv file from data recording from a machine, the problem is that, that machine could turn off for overcharged and I have the risk to lost data, in the technical support of codesys they recommend me to create a file write the header and close it, as you do, but after that oppened with am_append_plus but i need to follow the steps to read it, get a position and after that writting it... but I dont know how to do it because i dont understand well how to do it. Do you have any tutorial in where you explain this topic?
From, what i have understood, in case the machine fails, you want to read the last data you recorded to get the position, and then start writing more data again. Yes its true append_plus gives you the possibility to read and also write to the file. But then you have to write a whole new logic to read the file as well. I can help you privately if you get stuck. Regards
Very good video In this case, you use the Arduino programming serial port to carry out this communication with the modbus simulator. What would it look like using a MAX485 type converter?
Very clear and simple code, exactly what I was looking for. But I would like to connect the output to the MAX485 module. Then I could feed the data into the Modbus loop. How to do it?
