Description

What is NS8 TV00B V2?
• It’s an OMRON HMI / programmable terminal in the NS series. (omron-ap.co.th)
• “NS8” means an 8.4 inch class display. (omron.com.tw)
• “TV00B” is the model variant: the “B” usually indicates a black bezel/case variant. (omron.com.tw)
• “V2” means second version in that generation. (omron-ap.co.th)
From the datasheet / product specs:
Spec Value
Display 8.4 inch TFT (color) (GIẢI PHÁP TỰ ĐỘNG & THIẾT BỊ ĐIỀU KHIỂN)
Resolution 640 × 480 dots (GIẢI PHÁP TỰ ĐỘNG & THIẾT BỊ ĐIỀU KHIỂN)
Memory (project / user) ~ 60 MB (or 60 Mbyte) (omron.com.tw)
Colors Supports 32,768 (for BMP/JPG) (bpx.co.uk)
Communication ports 2 × RS 232C, 1 × USB (Type B, slave) (GIẢI PHÁP TỰ ĐỘNG & THIẾT BỊ ĐIỀU KHIỂN)
Supply Voltage 24 VDC (± tolerances) (GIẢI PHÁP TỰ ĐỘNG & THIẾT BỊ ĐIỀU KHIỂN)
Enclosure / protection Front side: IP65 rating (i.e. dust tight + water jets) (bpx.co.uk)
Dimensions / cut-out 232 mm × 177 mm × 42 mm (or similar) (TME)
Operational temperature, etc. Typical industrial range, and “product withdrawn” status in some catalogs. (TME)
Ethernet Not built in for this variant (i.e. TV00 versions lack Ethernet) (omron.com.tw)
Note: The “TV01 / …B” variants may have additional features (e.g. built in Ethernet) in that same series. (fa.omron.com.cn)
Also note: The NS series has been discontinued as per OMRON’s site (as of April 2022) — which means spare parts, support, or new stock may be limited. (omron-ap.co.th)

Pros (Strengths)
1. Good matching with OMRON ecosystem
Because it’s part of OMRON’s NS family, integration with OMRON PLCs and devices is smoother (native support, compatibility of functions, etc.). (jwtech.co.th)
2. Sturdy protection (IP65 front)
The front is rated IP65, so it’s protected from dust ingress and water spray — beneficial in industrial environments. (bpx.co.uk)
3. Sufficient display for many control tasks
8.4″ with 640×480 is modest but workable for many HMI tasks (buttons, indicators, simple graphics). The support for BMP/JPG images with 32,768 colors helps improve visualization. (omron.com.tw)
4. Moderate memory for projects
~ 60 MB is decent for many small-to-medium HMI projects (graphics, screens, data) though not huge by modern standards. (omron.com.tw)
5. Compact footprint
The dimensions (~232 × 177 × 42 mm) make it reasonable to mount in panels without huge space demands. (TME)
6. Predictable & known technology
Because it’s older and well documented, many engineers are familiar with it; troubleshooting and community knowledge may exist.

Cons (Weaknesses / Limitations)
1. No built in Ethernet (for this variant)
This model lacks an integrated Ethernet port, limiting connectivity flexibility (especially in modern networks). (omron.com.tw)
2. Limited resolution & size
640×480 is quite low by modern standards. If your interface demands high detail, charts, or many dynamic elements, this might feel constrained.
3. Memory limitations
60 MB is modest. Complex graphics, large amounts of historical data logging, multiple media files may push it.
4. Obsolescence / support risk
The NS series is discontinued per OMRON’s site. (omron-ap.co.th) That means less availability of spares, firmware updates, or official support in future.
5. Older connectivity standards
Using RS 232 for communications — slower, more limited — whereas modern HMIs often use Ethernet, MODBUS TCP, etc. You might find limitations in integration with more modern systems.
6. Bezel / color variant limitation
The “B” variant is black and lacks certain advanced features (like Ethernet) compared to other variants in series.
7. Display color mode tradeoffs
While it supports BMP/JPG with 32,768 colors, its native screen color count (256) may restrict some smooth gradients or visual richness. (omron.com.tw)
8. Limited future scalability
If your project scales, you may outgrow its capacity or connectivity.

Common Q&A & Usage Tips
Question Answer / Advice
Can I connect modern PLCs or networks? You can via RS 232, or add external gateways or converters. But you’ll miss out on native Ethernet unless you use a variant that supports it.
Is it still a viable choice in 2025? Yes for many legacy or modest projects, but newer systems may outperform it significantly. Also check support/availability of spares.
What software is used? CX Designer is typically used to configure NS HMIs. (GIẢI PHÁP TỰ ĐỘNG & THIẾT BỊ ĐIỀU KHIỂN)
What to watch in deployment / maintenance? Ensure you protect from extreme environments, plan for backup / spare units, and check supply of replacement parts. Also test how your communication with newer devices needs bridging (e.g. RS 232 to Ethernet).
Is there a better alternative? If you want built-in Ethernet, higher resolution, more memory, newer models (perhaps from Omron’s newer HMI lines or third-party brands) may offer more longevity.
