ENRON

From the firmware version 2.1, the EGW1-IA3-MB is added the feature conversion Modbus TCP to
Modbus ENRON.

This feature allows you to connect a Modbus Master, for example a SCADA, to a Modbus ENRON slave,
without needing to use the ENRON driver.

To use this mode, it must set the selected serial port in Modbus TCP to Modbus Serial Mode and enable
Slave Modbus ENRON option.
