Omron NS8-TV00B-V2 / NS8-TV00B-ECV2 Programmable Terminal (NS8 Series)

The Omron NS8-TV00B-V2 and NS8-TV00B-ECV2 are members of the NS8 series of programmable terminals (HMI). These devices provide a 8.4‑inch TFT color display with high resolution and a touch‑sensitive interface for machine monitoring, control, and data entry. The NS8 series is known for its long‑life LED backlight, multiple communication ports (including Ethernet on the ECV2 variant), and robust construction suitable for demanding factory environments. These HMIs are typically used with Omron PLCs (CJ, CS, CP series) but also support communication with other brands via built‑in drivers.

Functional Description

The NS8‑TV00B‑V2 and ECV2 units serve as the operator interface for a wide range of automation equipment. They can display alarm messages, real‑time trends, machine schematics, and operator input forms. The ECV2 adds Ethernet connectivity, enabling remote monitoring and control from a central SCADA system. The USB host port allows data logging to a USB memory stick, recipe upload/download, and screen backup. The built‑in ladder monitor allows viewing and editing of certain PLC logic directly from the HMI without a programming computer.

Programming and Software

Programming is performed using Omron’s CX‑Designer software, which is part of the CX‑One package. The software supports screen creation, animation, alarm management, and data logging. It includes drivers for all Omron PLCs as well as many third‑party controllers. Projects can be transferred via USB, Ethernet, or serial. The HMI also supports a “pass‑through” function, allowing the PLC to be programmed through the HMI’s Ethernet port.

Environmental and Approvals

The front panel is rated IP65, protecting against dust and water jets. The unit is UL 508 and CE certified. It is designed for pollution degree 2 and withstands vibration of 5g (10–150 Hz). The LED backlight eliminates the need for periodic replacement.

Applications

Typical applications include packaging machines, assembly lines, small to medium process control, and machine tool HMIs. The Ethernet model is preferred for integration into plant networks, remote diagnostics, and data collection.

Conclusion

The Omron NS8‑TV00B‑V2 and NS8‑TV00B‑ECV2 provide a reliable, high‑performance HMI solution with flexible connectivity, long life, and easy programming for industrial control and monitoring.
