Hi I had problem of time consuming of `pool()` method in my design using this library. - when the master is not polling any devices on modbus : 0 to...
Is there a way to change serial port for RTU comms to Serial1 so that I can do two simultaneous rtu loops (one slave one master) on half duplex?
In `ModbusServer.h` and `ModbusClient.h` I only see holdingRegisterWrite (write to a single register). Does the interface support an action for multiple writes, like `writeHoldingRegisters`? I know that the Modbus protocol...
Hi, I'm trying to have an Arduino Uno serve as a Modbus RTU server to simulate a device I need for work. I'd like to setup multiple holding register blocks...
The usual code for servicing a clients only works with one connected client at a time. ```cpp while (1) { ethClient = ethServer.available(); if (ethClient) { modbusTCPServer.accept(ethClient); while (ethClient.connected()) {...
I try this library to Arduino Mega 2560, but can not respond, and i try to arduino nano it success. ```cpp #include // ArduinoModbus depends on the ArduinoRS485 library #include...
Some modbus client (e.g pymodbus) assert dtr before transmitting, this lead to reset arduino to bootloader ( i spent one day around the problem on arduino-nano used as modbus-slave) Resolved...
Got it to work on a Portenta H7 - only testing Holding Register reading (all required in my application). I have a question about the software. Is it possible to...
Unfortunately ModbusRTUServer does not seem to work with the portenta machinecontrol, using the kitchen sink examples and connecting 2 machinecontrol boards together the client connection times out on every read...
Hardware: STM32F030C8T6 custom board, internal clock source, MAX485 chip (DE, RE connected together, DI and RO connected to PA8, half-duplex USART1) I got "Connection timeout" for any operation. With the...
