Frequently Asked Questions (FAQ)

What is the "Transparent Ready" concept for this module?

It means the module uses standard, open Ethernet and web technologies. This allows for easy, transparent integration with higher-level systems like HMIs, SCADA, and MES without proprietary software layers.

How do I access the embedded web server?

Assign an IP address to the 140NOE77110C module. Then, simply enter that IP address into any standard web browser on the same network to view diagnostic and data pages.

What is the advantage of having a web server on the module?

It allows for remote monitoring, basic diagnostics, and data visualization without needing the full engineering software. Maintenance personnel can quickly check status from any networked computer.

Does it require an external power supply?

No, it draws all necessary power (750 mA at 5V DC) directly from the Modicon Quantum rack's backplane, simplifying wiring and installation.

What is the difference between this and the 140NOE21110C module?

The 140NOE77110C includes a powerful embedded web server and is part of the Transparent Ready ecosystem. The 140NOE21110C is a more basic single-channel TCP/IP module without these advanced features.

Can it communicate with non-Schneider Electric devices?

Yes, through the standard Modbus TCP/IP protocol. This is a widely adopted industrial standard, allowing communication with a vast array of third-party devices, HMIs, and software.

What type of Ethernet cable should I use?

Use a standard shielded (STP) CAT5e or higher Ethernet cable for best performance and noise immunity in an industrial environment. Connect it to the RJ45 port on the module's front.
