UTLH21A

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.

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

To reduce hundreds of long wiring runs between the electrical room and the machinery, the nv controller features fi eld mountable I/O modules communicating with the controller over an optical loop. Using this approach, wiring material and labor costs can be greatly reduced. To protect the modules against conditions close to the machinery, the enclosure is rated IP54, which gives protection against dust, vibration, water splash and drips. Field I/O is housed in cabinets like the one shown below.

Two networks link the controller with the input/output modules:
• The Electrical ring (blue) services I/O local to the controller
• The Optical ring (red) services fi eld distributed I/O local to the machinery. Field I/O is housed in the cabinet shown below.
