Frequently Asked Questions

How many I/O modules can connect to one STBNIP2212?

The STBNIP2212 can manage a local drop of up to 63 STB I/O modules, depending on the total current consumption of all modules.

Can I use it as a Modbus TCP client/master?

No. This module operates as a Modbus TCP Server (Slave). It makes its I/O data available for a master (like a PLC or SCADA) to read/write. It cannot initiate requests to other devices.

How is it configured?

You can configure its IP address via the web interface, BootP/DHCP, or using Schneider's STB XPS Software. The web interface also allows monitoring.

What is the purpose of the two RJ45 ports?

One port connects to your main network switch. The second port allows you to daisy-chain to the next STBNIP2212 or device without needing an additional switch at the remote location.

Does it support PROFINET or EtherNet/IP?

No. The STBNIP2212 supports Modbus TCP/IP natively. For PROFINET or EtherNet/IP, you would need a different network interface module from the STB range (e.g., STBNIP2312 for PROFINET).
