How to use Emulation with PLC by modbus RTU connect.

I try to connect Mitsubishi FX3S by use Modbus RTU.

First I will get value fo sensor and control to Global Table.

But the value is not write to Global Table when model running and PLC is working.

I don't understand How is FlexSim can know coil or variable of sensor and control in PLC program.

X0 : Air Tube

X2 : Sensor

Y0 : Motor

Y1 : Air Tube

In the model I will use Motor and Sensor only. Thank You so much.
