Your project description is not clear. Do you want to have MODBUS TCP on one end (front end) and MODBUS RTU on the RS485 line (back end) or do you want ESP8266 to continuously poll RS485 line? COllission detection etc. does not arise on RS485 line because MODBUS is a Master/salve network Relevant Skills and Experience Lot ox experienc e in implementing MODBUS RTU, MODBUS TCP and such protocols as well as wireles devices. Can give you a comprehensive solution, once problem statement is fully understood Proposed Milestones $277 SGD - Project delivery. FInal price will depend on FInal specifications Please share all details. Can we discuss?
