Release of communication via Modbus® TCP/IP
In the EL3000, communication via Modbus® TCP/IP is blocked on
all Ethernet interfaces by default.
Note
The Modbus® protocol is an unsecured protocol (in the meaning
of IT security or cybersecurity), as such the intended application
should be assessed before implementation to make sure that
the protocol is suited.
Release communication via Modbus® TCP/IP
Figure 58: Modbus configuration in ECT
Implement the following steps to release communication via
Modbus TCP/IP:
1. Select '...\IO Modules\Modbus' in the menu tree of the
ECT Controller.
2. Select the ' Allow insecure Modbus TCP
communication' checkbox.
3. Set the required Modbus parameters, save the settings
and transfer them to the gas analyzer.
4. Communication via the Modbus TCP/IP protocol has now
been released.
Note
You will find detailed information regarding the Modbus® in the
description of the interface 'COM/EL3000/MODBUS'.
