The MicroSmart PLC by IDEC offers a true Open Architecture PLC: the OpenNet Controller (ONC). This unique PLC is compatible with three major industrial buses, DeviceNet, Interbus‑S and LonWorks. Expanding your I/O and existing network or designing a new system to work together with an existing one is now free of compatibility issues. This open network architecture gives users the control to design systems that are more powerful, cost less and provide flexibility as network technologies change.
