hello, sorry, there is no sample project yet for the Modbus RTU slave. thanks and regards.

hello, sorry for the late reply. you can add DataGrid object to show the alarms. then you can add also one Button for the Ack. I can explain the detail here, because it depends on your program. thanks and regards.

Hi, sorry for the late reply. actually it is possible, but I have no time for create the demo for this purpose. thanks and regards.

hi, i think you can debug the code from the Visual Studio, it will help you to point the problem. thanks.

yes, you are right

@@hadiscada can you give me little tutor about that? or where I cant find another video regarding that? i can't find it

untuk Modbus RTU Slave belum ada tutorialnya pak, tapi bisa kok pakai library EasyModbus ini, saya sudah pakai di aplikasi ModbusHD saya. Silakan dicoba sendiri ya.. maaf jawabannya telat. Terima kasih.

sorry i dont understand your question

@@hadiscada you know Ethernet IP protocol?

yes, it is free. but there is a paid license for higher preformance chart

Most welcome

bisa pak.

@@hadiscadasaya sudah mencoba nya pak cuman selalu mendapatkan notifikasi “ No Response from Modbus slave “ bagaimana untuk mengatasi nya pak ?

mungkin Slave ID nya harus diset/disamakan. coba pake aplikasi Modbus client/scanner yg lain dulu pak.

yes it is possible. maybe you can learn from this code: kzbin.info/www/bejne/bn-8aXxuZrBqp6s

halo.. maaf sy tidak tahu soal itu

for read data from S7 PLC you can see here : kzbin.info/www/bejne/gZCqeomMZ9J8b6c for read String you can add this script : if (type == "String") { string[] ardb = tag.Split('.'); if (ardb.Length > 1) { string sdb1 = ardb[0]; string sdb2 = ardb[1]; int idb1 = int.Parse(sdb1.Replace("DB", "")); int idb2 = int.Parse(sdb2.Replace("DBD", "")); object ival1 = plc.Read(S7.Net.DataType.DataBlock, idb1, idb2, VarType.Byte, 1); object ival2 = plc.Read(S7.Net.DataType.DataBlock, idb1, idb2+1, VarType.Byte, 1); int ilen = int.Parse(ival2.ToString()); object val = plc.Read(S7.Net.DataType.DataBlock, idb1, idb2+2, VarType.String, ilen); if(val!=null) sret = val.ToString(); } }

@@hadiscada thank you sir this help me read string from qrcode reader 🥰🥰🥰

hi, sorry I don't have a C# version for this project. but I think you can try to convert the script using this: converter.telerik.com

as a TCP server we dont need to define the IP address, but we need to define Port, but in this example project we are using default Modbus port (502) so we dont need to set the port in script, if you want to use other port then you need to set in the script. For your hardware client, I think you need to set the IP address in a same class of your laptop.

How to get ip for to read the device? Any example code for that?

Brother will you make video for Separate Serial and Ethernet connection in one program?

try this kzbin.info/www/bejne/bn-8aXxuZrBqp6s

you can read to some Text file which is contains the list of tags/node id here is the sample script : string filename = AppDomain.CurrentDomain.BaseDirectory + "uatags.txt"; if (System.IO.File.Exists(filename) == true) { using (var reader = new System.IO.StreamReader(filename)) { while (!reader.EndOfStream) { string stag = reader.ReadLine(); CreateVariable(rootMy, stag, DataTypeIds.String, ValueRanks.Scalar, 0); } } }

silakan pak

i am sorry that since January 2024, the Miqottt.com is suspended. so the project will not running well, you need to change to other MQTT server/broker. Thanks.

sorry I have no experience with that PLC, so I can't help you.

coba yg ini pak : mega.nz/file/cyxDUY6L#TWpMRphi0vO_nax2QuCmaNBRbTPLNFjAARnp-afzd9k

you can write script like this : try { PLC.Open(); } catch (PlcException ex) { MessageBox.Show(ex.Message); }

hi.. what is the problem? maybe you need to install the OPC DA library first in your Windows, here is the tutorial: kzbin.info/www/bejne/gX_bgniun7CSebM thanks and regards.

sorry i have no solution yet for this problem i hope you will found the solution soon thanks and regards
