Has made the integration of Arduino + ESP8266 + Software Opto22, implementing its environment scada right through IP and Modbus TCP Modbus RTU, the idea is to implement this hardware in the industry for both monitoring and control.
1- Arduino MEGA 2560 Master Modbus Potenciometer Display Oled
The Arduino configured as Modbus RTU master sends the value of the potentiometer to the slave in this case a slave simulator.

Updated 2017 for TrialCommand
2- ESP8266 Bridge Slave Modbus TCP – Slave Modbus RTU
ESP8266 test Registers as a bridge between Modbus RTU and Modbus TCP IP (Ethernet)
Updated 2017 for TrialCommand Modbus TCP/IP no libraries
3- Arduino Mega 2560 + ESP8266 Modbus RTU Modbus TCP IP Industrial Applications
ESP8266 + Arduino Mega ready to connect to SCADA OPC PLC Performing a mixed industrial network Modbus RTU Modbus TCP IP
4- Installation PAC Project Basic and Simulator PAC Sim
process software download and installation of software for Opto 22 controllers in this case download the PAC Project Basic, which includes software programming, design HMI and SCADA Runtime
5- Download Strategy Modbus TCP IP Master in PAC Project Basic Opto22
Opto22 example of strategy setting according to requirement as master or slave Modbus TCP, in this case for integration is configured as Modbus TCP master is discharged are configured holding registers for reading and writing respecting addressing.
