Frequently Asked Questions (FAQ)

What is the difference between the Class C30 and Class C20 web server?

The Class C30 web server in the 140NOE77111C is more powerful. It supports a greater number of concurrent connections and more complex web pages than the Class C20 version found in other modules.

How is this module powered?

It receives all required power (5V DC) directly from the Modicon Quantum rack's backplane through its connector. No separate external power wiring is needed.

What can I do with the embedded web server?

You can create custom web pages to display real-time process values, alarms, and system status. This allows for remote monitoring and basic control from any computer or mobile device on the network.

Is this module suitable for harsh industrial environments?

With its wide temperature range (up to 60°C) and high humidity tolerance, it is suitable for many industrial control panels. However, the IP20 rating means it must be installed inside an enclosure for full protection.

What does "Transparent Ready" mean for users?

It ensures the module uses non-proprietary, standard IT protocols (Ethernet, TCP/IP, HTTP). This makes it easier and faster to connect to higher-level systems like MES or ERP without custom drivers.

Can I replace a 140NOE77110C with this 140NOE77111C module?

Physically, they are compatible. However, the 140NOE77111C has a more capable C30 web server. You must update your Unity Pro configuration to fully utilize the new module's features.

What is required for network setup?

You need to assign a unique IP address to the module using Unity Pro software. Then, connect it to your plant network using a standard RJ45 Ethernet cable for immediate communication.
