Hi Freelancer, My project is to write arduino Mega2560 code to enable MODBUS TCP/IP between this mega2560 and the slave simulator software present in my laptop. The functions to be accomplished are; 1, Write a coil to change its status, 2. Read that coil status and display, 3, Read Holding registers and 4. finally input registers.
Note: Those who accomplished the MODBUS TCP/IP using Arduino projects alone send you interest.
Hello, I could help you, I am a Mechatronic Engineer and I have 3 years of experience in the area of communication, ethernet management, Modbus, Modbu TCP / IP among others
I am very experienced with Modbus communications with Arduino controllers.
I have already completed a few projects using Modbus communications as primary control and I understand very well how to ensure the code is not too complex that it will cause delays and skip packets.
Please contact me to get started with your project.
I already have code for -
1- "wise 4012" read by arduino and send to server.
2- megaAVR+ ethernet board worked as host read from device- (Pc modbus -rtu simulate).
3-arduino uno+ethernet board worked as modbus-rtu device emulate.
I have 5 days for explain you, how it works.
