Good evening, have you already communicated via Modbus a Chinese PLC FX3U with a remote io with digital input and output? Using function 02 to read discrete inputs?
Hi sir can u tell me how can I configured PLC as a master and peristaltic pump as a slave.As of now the data from STM32 is shown on the Modbus slave.plz sir tell me how can I configured??
I have problems with the SAMDRAW 5.0 Software, when I configure it as Modbus Slave, I cannot add the addresses in the elements, for example a numeric display, there is no accept the address. I can't generate "3x" for the sentence and it doesn't accept it, this part of the address must be generated in a combolist in the addressing section
@@automationtraining385 If it is correct, that way it does not work, the HMI does not respond, I have also tried to do tests with MODSCAN as Master instead of the PLC trying to communicate with the HMI SLAVE and it does not work ,,, thank you very much for the support I appreciate
Hello sir, can this plc work as the modbus slave & master at the same time? Bcs I need the PLC to read other PLCs (as the master) then connect it to HMI (as the slave). And can it be done with the same RS485 port?
This plc has 2ports. Rs232 and Rs485 . rs485 use as a master to read other plc. rs232 port that is download port used for both download and communication to hmi.It will work
@@automationtraining385 thank you sir. So we need to set the register D8120 with protocol modbus slave and modbus master right? Do you have the program example regarding this? Thanks once again sir I need it for my study project
only set modbus master setting to read the slave plcs. for hmi communication no need to do setting in plc. See this video and program link attached in description of thus video
@@automationtraining385 Thank you. Sorry, i want to ask again, how do i know the response from modbus communication has been successfull or not ? Thank's before
Hi, can you please make a quick video with this PLC connected as Master.... (FX3U Modbus RTU Master) with a Panel Samkoon (EA4.3a Modbus Slave) ? please
Please tell me clearly. You want to control the plc by hmi or control the hmi by plc In most of the cases hmi is master only. So we can control the plc( slave) through hmi. If hmi is slave then plc(master) is going to read and write the data of hmi.so for that you need only address ( internal address of hmi LB or LW). x3 x4 function you required in plc not in hmi.
It is a very important and clearly explained video
Your video is great, greetings from Peru.
Thank you very informative
EXCELLENT TUTORIAL.
Good evening, have you already communicated via Modbus a Chinese PLC FX3U with a remote io with digital input and output? Using function 02 to read discrete inputs?
Already not done. But if i have remote io device details then only able to tell communication possible or not
Hi sir how i can connect temperature sensor with this plc using modebus.i want to learn analog programing for this plc.
I have 2 pcs fx3u lolate.. So i wanna conect as master and slave.. Where is need modification program?
sir same program can be use for fx1n plc ..?
Sir if slave wire break and slave not response to master then how to know in master i mean wech relay / flag for slave error?

Hmi is slave means it can not do any action. So only it is not generating

Ok thankyou sir. What is the serial setting for the rs232 sir?
I mean, can the RS232 port work as modbus slave sir? Because i want to connect it to HMI via modbus protocol
Brilliant!!!
I'm very interesting for learn it. can i get a program Ladder diagram for PLC ? Thank you
Program link is attached in description. Check it
@@automationtraining385 Thank you. Sorry, i want to ask again, how do i know the response from modbus communication has been successfull or not ? Thank's before
@@hendraarya9869 you will get slave data in master plc if you execute read code.
@@automationtraining385 Sir, do yo have tutorial or reference, communication PLC FX3U with Arduino ? Thank's before sir
@@hendraarya9869 no

@@automationtraining385 Beforehand thank you very much
It would be the Master PLC controlling a slave HMI, this is what doesn't work for me
