UTLH21

The UTLH21 industrial controller Unifi nv series controller is an advanced industrial controller launched by Toshiba. This controller has made significant improvements in design, surpassing existing V-series controllers and has been widely used worldwide.

The main features of the UTLH21 Unifi nv series controllers include:

High speed I/O communication: This controller adopts the industry’s first 100Mbps fault-tolerant ring network “TC net I/O”, which is used to connect I/O devices installed remotely on site. This high-speed I/O communication capability greatly improves the efficiency and stability of data transmission.
Powerful processing capability: The UTLH21 controller has functions such as high-speed logic, sorting, motor speed control, and continuous control. It supports high-speed processing of bits and integers (20ns), floating-point addition/multiplication (120ns), and short control cycles (0.5ms~1000ms).
Large capacity program and data storage: This controller has the ability to store large capacity programs and data. The program capacity can reach 256 kilosteps (instructions) and can last up to 385 cycles. Meanwhile, it also has high data capacity, including 256K words for local/global variables and 16384 16 bit words for I/O variables.
Rich interrupt and scalability: The UTLH21 controller supports a total of 16 interrupt tasks and supports multi controller configurations, with a maximum of 3 controllers installed per chassis. In addition, it also supports up to 4 communication modules to meet different communication needs.
Redundancy and reliability design: In order to improve the reliability and stability of the system, the UTLH21 controller adopts a redundant module design. At the same time, the error correction ECC circuit in the internal memory of each module can also provide error checking and correction functions.
Directly executing IEC standards: This controller can directly execute the four languages in IEC 61131-3 standards: LD, FBD, SFC, and ST, thereby improving control speed.
Overall, the UTLH21 industrial controller Unifi NV series controller is a powerful and stable industrial controller. It is suitable for various industrial automation and control systems, which can help enterprises improve production efficiency, reduce energy consumption, and improve product quality.
