-Login to the browser page of the Moxa device to see the status of inputs and outputs and also other information.+  * Within the device web page, in the main menu, within User-Defined Modbus Addressing, select Analog Inputs, Digital Input/Outputs (or similar): 
 +     * Make sure "Enable Modbus/TCP Slave Protocol" is enabled 
 +     * Within the table all the addresses of the available data points are listed. E.g. "AI Scaling Value (Float)" at "0520" as Input Register (read-only), Reference Address "30521" 
 +     * Within Terra4D use "Analog Input" with the address 520 (the 30000 is automatically added by selecting Analog Input).
