Hello, thanks for your video. Im trying to make it work on a Mega but the program get stuck in the mb.config line. I have tried almost everything I found on the internet but it wont work. Can you give me some advices please? Thank you.
When i start the script for esp (with if (c=4) (send 40 for reg1 for exemple and if c=5 send 30 for regs1 ) i have the same value in plc data block all time ( with c=5 i have 40 also ) what the prblm!!
Hey, buddy! Can you help me, please? I'm following the example of your video, but when I insert in Step 7 the second block Modbus Client and Do the settings to write in arduino nothing happens. My second Modbus communication block never works... The "Done" status of the block always becomes false.... Would you have any tips to give me? I'm using an S71200 with an Arduino and a shild ethernet.
Hello, if first block works fine, then communication should be alright. Does error flag coming up? It can be present just for one cycle, make a trap for error flag and error code using set coil and move error code. What is error/status code? Double check that all parameters are correct (mode, address, connect definition). Communications are always very difficult to troubleshoot.
Really nice tutorial, thanks a lot for your time. I have question, why sometimes we have to add 4000 or 3000 (depend on the type of register) to the server data address, and sometimes not, for exp. you did not add, but I saw on the few turotials people added. Does that depand on the modbus library version?

Good tutorial, I can read from Arduino, but when i send data to the Arduino the serial monitor gives only 3 times 1 like is set in the program from the Arduino. I think something is not right with the program. Hopefully you can help me with this issue. mb.addHreg(reg5_HREG, 1); mb.addHreg(reg6_HREG, 1); mb.addHreg(reg7_HREG, 1); The upper 3 lines are a little strange. The three 1 is what i see in the serial monitor, and not the values what i put into the send array from my siemens. its the first time that i work with the arduino thus maybe i be wrong. Thanks in advance Frans
Hi, statement mb.addHreg(reg5_HREG, 1) means declaration of holding register, value "1" is just initial value (void addHreg (offset word, word value), github.com/andresarmento/modbus-arduino ), that's why it's located in steup(). It's looks like PLC is not writing to Arudino register, so Arduino just display initial value. Download Modbus slave tool and test it with PLC github.com/ClassicDIY/ModbusTool
