Tnx Jimmy for u'r nice video i want to simulate modbus rtu with s7-300 and i cant find that how can i make conection between the simatic manager and modbus slave simulator
Nice lesson .. but what if i have to transfer status bits (1xxxxx) along with registers (4xxxxx) .. will it be in the same buffer or additional buffer needs to be created ????
As I know, you can not read FC02(1xxxx) resistor with buffer DB. only buffer DB can read with FC03, FC06, FC16. Modbus communication function codes (1, 2, 4, 5, and 15) can read and write bits and words directly in PLC physical address. Read bits 10001 to 18192 is PLC IO I0.0 to I1023.7
Thank you so much. I just watched your video and got it working. Didn't have any luck before I watched this 🙂
Thank you for your reply :)
Hi Jimmy
Good video
The passion you showed in teaching is amazing
Thank you :)
HI Jimmy thanks bro so clear
could u do some more videos
i wanna know physical connection
this video would help to you. ua-cam.com/video/1fMaw6GATws/v-deo.html

thanks Jimmy. Nice video.
you are welcome
how about hardware?
안녕하세요 좋은 영상 감사합니다.
다름이 아니라 모드버스 폴에서 계속해서 바이트미싱 에러가 뜨는데 혹시 뭐가 잘 못 된 걸까요? baud만 9600으로 했는데 에러가 뜨네여ㅠ.ㅠ
thanks Jimmy
You are welcome :)
How can i use PLCsim because i don't have real PLC
You can not test Modbus RTU with PLCsim :(
@@jimmyplc7613 Can you tell me how can i communicate PLC and Python with RTU
Thanks
nice lesson. Many thanks
You are welcome :)
nice lesson! it is work fine
Thanks!
It is work for siemens s7 1500?
Yes. only program is same. but the hardware is different from this video.
How to send Real values through this ??
What is real values?
@@jimmyplc7613 it is floating values ..
Thank you
jimmy. where is tutorial Modbus Master?
Sorry. I have no time to make video :(
Thx
You are welcome :)
