Usage in Remote Access Applications
In some applications it is essential to do monitoring or even control remotely, e.g. at regional distributed pump stations.
In such cases the use of standard Ethernet is of great benefit because standard routers, gateways etc. can be used.
Take measures where only authorized users have access to the remote installation and can read or write
data.
The following figure shows a system with a central SCADA (supervision control and data acquisition) station and
several remote locations.
The SCADA system is connected to the remote locations via a model or other wireless or wired network.

Modbus TCP counts registers beginning with the digit 1, but on the bus, registers start counting from zero.
The addresses in this manual describe the addresses that are transmitted on the network.
• Separate access to each data type (boolean values or analog values) of each module.
This requires sending several Modbus telegrams to the dedicated addresses
