NS-V2 vs NS-B Comparison Table (Programmable Terminal Replacement)
This table summarizes the differences in specifications between the OMRON NS-V2 programmable terminal (NS□-□□□□-V2) and its replacement, the NS-B series (NB□□W-TW01B-V1-S). Yellow cells are items whose specifications changed from the NS-V2. For the meaning of the symbols, see the legend at the end of the page.
Key specifications

Recommended replacement models
The following NS-B replacements are recommended according to panel size. Panel cutout dimensions change, so using the matching attachment allows mounting without machining the control panel.

Change in RS-422A/485 connection: NS-V2 was connected with loose wires to the terminal block (RDA-, RDB+, SDA-, SDB+, FG) of the RS-232C/RS-422A converter unit, but NS-B connects directly to the D-sub 9-pin COM2. Refit the connector according to the signals in the table above, set the communication standard to "RS-422A" (or "RS-485") in [Communication Settings] in CX-Designer V4 and transfer. The PLC connection cable NB-RSEXT-2M (RS-422A/485, 2 m) can also be used.
Barcode reader: For the V410-HDS4608SR, supply 5 V with the AC adapter V410-AC0-1 and use the connection cable V430-WPLC-2M.

Screen Data Conversion Rules
When converting NS-V2 screen data (.IPP) for NS-B with [Tools] - [Convert] - [Import] in CX-Designer V4, the display positions and sizes of parts are converted according to the following rules based on the resolution difference (the Y coordinate is not offset).
| Model before conversion | Model after conversion | X coordinate offset | Part size scale |
|---|---|---|---|
| NS15-TX0□-V2 | NB15W-TW01B-V1-S | 0 | 1 |
| NS12-TS0□ (no suffix / -V1 / -V2) | NB10W-TW01B-V1-S | 112 | 1 |
| NS10-TV0□ (no suffix / -V1 / -V2) | NB10W-TW01B-V1-S | 112 | 1.25 |
| NS8-TV0□-V1／TV1□-V1／TV0□-V2、NS7-SV0□ | NB7W-TW01B-V1-S | 80 | 1 |
| NS5-SQ0□-V1 / SQ0□, SQ1□, TQ0□, TQ1□, MQ0□, MQ1□-V2 | NB5Q-TW01B-V1-S | 0 | 1 |
| NSJ□、NSH5、NSA12-TX01B、NS-Runtime | Cannot be converted (convert the model to V2 first) | ||
Before converting, set the PC display scaling to 100% (the scaling affects CX-Designer font sizes). Parts placed outside the screen on the NS-V2 may become visible due to the resolution difference.

Overview of the NS-V2 → NS-B Replacement Procedure
Caution: always check the existing equipment for positive grounding (24 V side grounding)
The internal power supply of the NS-B is non-isolated. If the +24 V side and ground side of the NS-B are short-circuited (24 V side grounding), +24 V and power GND are shorted via the signal GND/FG of a connected PC or similar, leading to equipment damage. Check both the wiring diagrams and the actual equipment with a tester or similar.
If they are short-circuited, either Measure 1: change the wiring so the 24 V side is not grounded, or Measure 2: insert an isolated DC power supply between the external power supply and the NS-B for isolation.
- Preparation: check for positive grounding → upload screen data from the NS-V2 (CX-Designer Ver3, USB) → convert for NS-B in CX-Designer V4, check and fix places affected by function changes
- Removing the NS-V2: power OFF → remove all cables → remove the memory card (if used) → remove from the operation panel
- Mounting the NS-B: mount the attachment → mount the NS-B → wire the cables (cut off the Y terminals and connect power directly to the terminal block; rework RS-422A/485 to D-sub 9-pin) → insert USB memory (if used)
- Startup: power ON → download screen data (CX-Designer V4, USB) → check written values, screen transitions and displayed values on the actual equipment → start operation
If CX-Designer is not available on site, you can turn ON DIP SW1 and SW5 on the NS-V2 to automatically upload to the memory card (BANK1) and read it on a PC. For the NS-B, write it to USB memory and start with DIP SW1 and SW2 ON to download automatically (return SW1 and SW2 to OFF afterwards).
Summary of Points to Note When Replacing
| Item | Description |
|---|---|
| Positive grounding | The NS-B power supply is non-isolated. In panels with 24 V side grounding, +24 V and power GND can short via the FG of a PC etc., damaging equipment. Always check with wiring diagrams and a tester, and either wire so the 24 V side is not grounded or insert an isolated DC power supply. |
| Connectable Devices | Serial connections to Mitsubishi, Siemens, Rockwell, Yokogawa, Yaskawa and others, Modbus TCP, Trajexia, Controller Link and printers cannot be connected. OMRON SYSMAC (serial / FINS / EtherNet/IP), Modbus (serial), temperature controllers, Memory Link and barcode readers can. |
| Supported standards | Does not support marine standards, UL hazardous locations or UL Type-4. The UL standard changes to UL61010-2-201. |
| Panel cutout | The panel cutout becomes smaller for all sizes. The matching attachment (NB□□-ATT0□) allows mounting without panel machining. Depth of the NB10W increases from 48.5 mm to 54.0 mm. |
| Cable connection direction | Port direction changes on models other than NB15. If there is no rear space, use a D-sub side-exit hood (XM2S-0921 / MAH90-9-M2.6) or a commercially available side-exit connector. |
| Power wiring | Y terminals cannot be used. Cut off the Y terminal, strip 6.5 mm of insulation and fix the wire directly to the terminal block (0.3 to 0.5 N·m). |
| RS-422A/485 | No converter adapter needed. Wire directly to the D-sub 9-pin COM2 and select the communication standard in the CX-Designer V4 communication settings. |
| Barcode reader | COM2 does not supply 5 V. Supply 5 V with an external power supply (such as V410-AC0-1) and connect with V430-WPLC-2M. |
| Screen data | Convert with CX-Designer V4. NS12/NS10/NS8 get a wide resolution and part positions are offset in the X direction (NS10 is scaled 1.25×). Parts placed outside the screen may become visible. |
| Touch operation | Two-point simultaneous press is not possible. Open the system menu by double-tapping one of the 4 corners. Calibrate periodically because it uses analog resistive film. |
| Retained memory | Because saving happens every 30 s, changes made just before a power cut may not be retained. For immediate save, turn $SB62 ON. |
| Date and time | The display range is 2024-01-01 to 2062-01-09. Being battery-free, time is retained for about 10 days (40°C). To synchronize with the PLC, use the SAP [PLC→NS time adjustment]. |
| System memory | $SB/$SW related to battery, video, contrast and printer are changed to reserved. Screens and PLC programs referencing them must be fixed. |
| Repair period | NS-B: 5 years from manufacture date (5 years after discontinuation). Repairs are handled by replacement with a new product. |
For the procedure for migrating programs and screen data, refer to OMRON's "Replacement Guide: From NS-V2 to NS-B (SBSA-099A)".
