SimpleModbusSlaveArduino:83: error: cannot convert 'Serial_ ' to 'HardwareSerial' for argument '1' to 'void modbus_configure(HardwareSerial*, long int, unsigned char, unsigned char, unsigned char, unsigned int, unsigned int*)'

The Slave code fails with In function 'void setup()': However, I can't get the thing to compile for a Leonardo. The examples given seem to be a compatible pair designed to talk to each other, something sadly lacking in the other things that my trawl has thrown up So I'm trying to use 'SimpleModbusMasterV2rev2' and 'SimpleModbusSlaveV10'. I've used them for a number of years but now I need to use the 485 protocol.Īfter various false starts with the old libraries that the internet throws up I have just come across this thread and the 'simple-modbus-master' libraries. Hi, I'm beginning to get very frustrated with loading modbus on to arduinos.

Mail.: me the dop panel delta display software + arduino libraries + circuit diagram Hi vietnam friend you made the tube modbus communication dop panel, send me the arduino library Why 4002? Because in Delta HMI register address, address 0 will be 40001, so if you need to access register 10, it will be 40011 in Delta HMI. So, in HMI you can access with address 40001 for VAL_LED (HMI write value into this register such as button input) and 40002 for VAL_POT(HMI will read from this register such as number display?). Modbus_update_comms(19200, SERIAL_8N2, 1) Īs you declared in your code, register of VAL_LED is READ register (address 0) and VAL_POT(address 1) is WRITE register. port variables and slave id dynamically in any function.

modbus_update_comms(baud, byteFormat, id) is not needed but allows for easy update of the Maybe you will need this line of code: modbus_configure(&Serial, 19200, SERIAL_8N2, DEVICE_ID, T圎nablePin, HOLDING_REGS_SIZE, holdingRegs)

State a clear question, clear enough for even for non-native speakers like me.

provide a schematic of your wiring and a real picture of your setup.

tell us, for what hardware platform you are developing,.

Tell us the exact page, where this information starts.

If you need support for your devices, post a CLICKABLE link to the manual, where we can clearly see the modbus registers.

I don't say that it wouldn't be possible, but for what use case? Either I need something dedicated for my purpose - or something to test my slaves. I assume most of us only have implementations for their specific requirements, with limited support of their needed slave devices. You might be able to imagine what work would be necessary to do something similar on an Arduino. If you have a look at some of the modbus test tools for PCs, you'll see how complex a "flexible" software is. With such a community, I believe you can help me. You can either invest more money or you reduce your expectations if you have no time.Īnd I don't want a product that is not flexible, I want a device that It's as simple as that: out of three given parameters Therefore, if you want to write single values to your slave, you should search for another library. It's not the preferred way to write data once. The simplemodbus Master library - we are talking about in this thread - is perfect for reading data over and over again. I want to be able to read and write data from these devices from a remote site on a website.
