The Address is the starting address of the Modbus RTU device. The different address ranges

refer to different input and output types (see the Modbus protocol for details). The Length

refers to the number of data points to be read from the device. The Scan_Interval is the

speed at which we wish to read the values from the device.

Restoring to Factory Configuration

All of the protocols can be returned to their original factory settings by entering the

configuration for that protocol and clicking the Restore Defaults button.

Disabling protocols

To disable a protocol, select the personality, enter the configuration screen and delete the text in

the text box. Click the Submit button to save your changes. You can restore to the factory

defaults by clicking "Restore Defaults".

Protocol Map

Selecting the Protocol Map option in the navigation menu will display a table showing the

mapping of the different protocols. This is how the Ethernet-side and serial-side protocols are

linked together. Every active serial protocol is mapped to every active Ethernet protocol and

vice versa. The map is created by the FST software and is based upon the memory addresses

and data array lengths you select in the protocol configurations. If you change the length of data

arrays in your configuration, the addresses of mapped protocols will change with it. For

example:

We have Modbus RTU and DF1 mapped to Modbus TCP. The Modbus RTU configuration has

a length of 20 it maps as shown here:
