The JNIOR OS has a variety of features that make it feel more like a PC than an industrial controller or small programmable logic controller.  With features like Telnet, FTP, NTP, file directory, JVM, logs, multi-threaded applications, multiple network connections, plug-and-play expansion I/O, and a variety of user-friendly features built into the OS, the JNIOR is easy to configure, operate and maintain.

The JNIOR Series 4 OS, JANOS, is a multi-tasking operating system that executes on a powerful 32-bit microprocessor with 32 MB DRAM, 2 MB SRAM, and 64 MB flash memory.  This dynamic OS includes a full-feature Java Virtual Machine (JVM) developed by INTEG.  The JVM runs standard Java programs with no special classes or compilation required, allowing easy development of custom code for execution on the JNIOR Ethernet I/O Controller.

JANOS contains an advanced, modern web server capable of executing HTML5 code and web sockets.

A variety of software programs are available for the JNIOR that bring a lot of functionality to the JNIOR without any programming. Customized programs can also be written in Java.
