4.4 MN/RC modbus

This project shows variables that are set when the Main Controller is connected with Remote control
and modbus. The information on the screen are divided in several items:

1. Read buffer in MN has the data which reads by Modbus master.
2. Write buffer in MN has the data which written by Modbus master.
3. Read/Write in RC is the modbus information.
4. Modbus Device address is set in E2Prom
5. Mobus_write_enable shows when the Modbus master can write.
6. Exit timer shows when the Modbus master is disconnected when no data is send.
7. TX and RX bytes between Modbus master and MN.

4.5 RC display

This project shows information on Remote Control and Timer saved information.
