This is a great video sir. And many thanks. Tried it and it worked. However, i have got 2 questions. 1. So you do not need to map the MB_Data.Hold_Reg to the PLC tags in order to read or write to it? Will it still be same for analog input cards like reading the Flow, Pressure and Temperature sensor data? 2. Would mapping also be required between MB_Data.Hold_Reg (Buffer) and other DB's in the program? Or will it work straight away just like the PLC tags? For instance, DB_Powermeter?
hello bro....perfect videos i have one question pls why you give specific values in connect registers(64, 1, 11, 502). from where we can get these values?? and these values depend on what???
502 is default port of modbus you can find them in siemens document: support.industry.siemens.com/cs/attachments/102020340/net_modbus_tcp_s7-1500_s7-1200_en.pdf
Excellent video. Thanks for sharing. I've successfully done Modbus Server like on the video, but when I try to read data from Micrologix 1400 Modbus Client it does not work. I get the error "Local communication channel is shut down".
hello, great video reference for PLC siemens, in my case, i'm trying to connect PLC fatek fbs series as the master to read and write value to a software called modbus slave, i haven;t be able to communicate my PLC with modbus slave, maybe you can help me by discussing this matter? thank you
When i connect plc with node red.,Modscan not working.. Again when use Kepserver, modscan and node red.. I saw only one slave work with this MB server.. What's reason may i know please?
Maybe the IP address PLC and PC or connecting device are not in same network. For example PLC=192.168.0.1, PC or connecting device must be 192.168.0.xx

Good video...I want to ask how if 1 Siemens PLC communicates with many ESPs at once? What needs to be changed is the ID?
Thank you,
I don't have experience for creating multiple modbus client, maybe you should create multiple modbus function and with different ID
@@YaserAliHusen Hi, I've tried but still failed...can only 1 esp connect, can you help me?

Is the IP address both of server and client in same IP node?
For example same in 192.168.0.xxx
Or you can test using modbus clientX software
When did u create TCON_IP_v4 data type ? what is the details of it ? am i miss something ?
You can see the detail in ruclips.net/video/YuRjIp0cipA/видео.html
Thanks video,,, how to change start address like a start on 40100 ?

Hello,
I am sorry, I dont have experience using PLC Fatek.
Is there any tutorial how to setup modbus in Fatek?
When i connect plc with node red.,Modscan not working.. Again when use Kepserver, modscan and node red.. I saw only one slave work with this MB server.. What's reason may i know please?
My experience, Modbus server only connect with 1 modbus client.
I dont know, is it related with your problem?
@@YaserAliHusen yes..
Hi I am unable to see the "OPC " option and also "Protection of the PLC configuration data" options. Please help me
Click on PLC hardware displayed in software(in upper half of middle of TIA software). Then those options should appear under Properties.
can we do this with PLC SIM ?
i dont have plc hardware, i'm using plc sim and i did same as like you, but connection failed with mb client
Hi, thank for watching my video.
In video I use real PLC.
Sorry I don't have experience using PLC Sim, maybe there is configuration related connection
@@YaserAliHusen but u didn't used mb client
@@industrialautomation1992 , As I remember, I set the PLC as Modbus Server
Ok
Unfortunately i couldn't connect
Maybe the IP address PLC and PC or connecting device are not in same network.
For example PLC=192.168.0.1, PC or connecting device must be 192.168.0.xx
