USIO21 TOSHIBA 工业控制器 统一nv系列控制器

Toshiba’s latest industrial controller, the Unifi ed nv Series controller, is a big step beyond the existing V series used in industry around the world. The capabilities include high-speed logic, sequencing, motor speed control, and continuous control. Highspeed I/O communication uses the industry’s fi rst 100 Mbps fault tolerant ring network “TC-net I/O”, linking remote, fi eld mounted I/O.
Feature Details
High-speed processing Bit and integer processing: 20 ns; fl oating point add/multiply: 120 ns Short control cycle Three separately scheduled periodic tasks: 0.5 ms to 1,000 ms Large program capacity Programs up to 256 kilo steps (instructions), up to 385 periodic programs High data capacity Local/global variables 256 K words; I/O variables 16,384 16-bit words Interrupts Total of 16 interrupt tasks
Multiple controllers Up to three controllers per chassis; up to 4 communication modules; redundant controller and network confi gurations possible Programming fl exibility Four IEC 61131-3 standard languages: LD, FBD, SFC, and ST Memory reliability An error-correcting ECC circuit in the internal memory of each module
The main features of this powerful controller are:
• Fault tolerant ring 100 Mbps I/O communication
• Enhanced speed by direct execution of IEC standard control languages in ASIC hardware
• Higher reliability using redundant modules, and error checking and correcting ECC memory
• Gigabit supervisory control network
