Q: What are the suitable applications for the NB3Q-TW01B-V1?
A: Its compact 3.5-inch size is suitable for equipment with limited installation space, such as small packaging machines, textile machinery, HVAC terminal control, and small automated special-purpose machines. It is suitable for scenarios requiring on-site monitoring but with limited panel opening size.
Q: What software is used for programming? Does it support offline simulation?
A: It uses the Omron FA integration toolkit "CX-One" (which includes NB-Designer). Offline simulation is supported, allowing you to simulate and debug the screen program on a computer without physical hardware.
Q: What is the difference between the NB3Q-TW01B-V1 and the NB3Q-TW01B (older model)? Can they be directly interchanged?
A: Yes, they can be interchanged. The NB3Q-TW01B-V1 is an upgraded version (replacement model) of the NB3Q-TW01B. The main differences are that the V1 version optimizes power consumption (9W→4W) and weight (305g→320g), resulting in more stable performance. The mounting hole size (119×93 mm) and communication interface configuration are the same, and they can be used interchangeably.
