UTLH21 Unifi ed Controller nv Series

UTLH21 Unifi ed Controller nv Series

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

Description

Overview

Essential details：UTLH21 Unifi ed Controller nv Series

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

UTLH21 Unifi ed Controller nv Series

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.

The nv series I/O modules can be mounted in the electrical room or remotely, adjacent to the machinery or process. TC-net I/O communication with the local I/O is over an electrical Cat5e fault tolerant ring (shown in blue), which connects to electrical serial I/O modules (SIO). Field mounted I/O is connected using fault tolerant optical rings (shown in red), which connect to optical SIOs, while the drives typically use an optical converter or hub, (shown in yellow). I/O Communications over TC-net I/O Large drives such as the cabinet-mounted TMdrive10e2, 30, 50, and 70 are connected in star confi guration to a hub device. Smaller TMdrive-10e2 family drives mounted in multistage panels share an electrical multidrop cable using an optical-electrical converter mounted in the drive panel. Other communication networks such as Modbus and Profi bus (shown in green) can communicate over TC-net I/O using special modules
