In addition, the TOSDIC VS allows the reuse of existing instrumentation and control assets, making it possible to transfer process control assets and know-how to the next generation.

Role as an edge computer to accelerate fusion with DCS controllers and IT solutions

Computing function of the typeL

Edge computing

The typeL is a DCS controller that integrates both control and computing functions.
While conventional DCS controllers require a separate PC to analyze important process data, the typeL is capable of storing and analyzing such data and thus makes it possible to improve production processes in a timely manner.
Therefore, the typeL is the ideal choice for edge computing applications that utilize the data collected at manufacturing sites for IT solutions.

High-speed data transfer

The typeL shares tag information with the internal computing function at high speed.
Since the computing function runs under both Linux and Windows, IT solutions on other computers can be ported to the typeL without modification.

Secure environment with s hared memory

The typeL transfers data between the computing and control functions via shared memory, eliminating the need for a communication program to transmit data to the computing function.
The typeL allows secure data sharing since data is not transmitted through any external network.

Architecture to realize the edge computing
capability of the typeL

Highly reliable high-performance DCS controller

Unified Controller Vm series typeL

High performance and reliability

The typeL provides high-speed control scans and tracking to make it possible to collect process data from widely dispersed devices in a system and shut down equipment in the event of an emergency. The typeL provides excellent reliability as it supports redundant state monitoring between active and standby controllers, which is pivotal for achieving redundancy.

High-capacity tag storage

A single unit of the typeL supports approximately double the number of tags of the previous model. Therefore, the typeL helps reduce the number of stations in a process control system.
Since the typeL can communicate with the existing DSC controllers, a process control system can be composed of different generations of DCS controllers.

Inheritability

The typeL supports the nv-Tool, an engineering tool that has been used with Toshiba’s conventional industrial controllers. Therefore, the typeL allows the reuse of existing program assets and the inheritance of design know-how.

Intuitive and easy-to-use HMI

Human-machine interface (HMI): OI-VS10/OI-VS20

Design compliant with the ISA-101 standard from the International Society of Automation (ISA)

The human-machine interface (HMI) of the TOSDIC VS is designed in accordance with the ISA-101 standard from the International Society of Automation (ISA). Therefore, the TOSDIC VS can be used intuitively both by novice and experienced operators. It is suitable even for operators who have no experience with instrumentation engineering. The TOSDIC VS also supports operation consoles that have been conventionally utilized for plant operation.

Highly user-customizable architecture

The TOSDIC VS provides various highly user-customizable options.

High capacity

With an increased database capacity, the TOSDIC VS is capable of storing trend data for a long period. Therefore, the TOSDIC VS is suitable for analyzing long-term trends in equipment and system conditions. The TOSDIC VS supports the monitoring of up to 8,000 tags per system (up to 20,000 tags with a future enhancement), and its HMI allows up to 14 stations (up to 22 stations with a future enhancement) to be connected.

Designed in accordance with the ISA-101 standard from the International Society of Automation (ISA), the TOSDIC VS allows intuitive plant operation.

Operation from anywhere, anytime

Web architecture of the human-machine interface (HMI)

Accessible 24/7

The HMI incorporates web technologies to make it possible to monitor a plant’s operating conditions and perform troubleshooting via a web server from anywhere, be it the headquarters, your office, or your home. In addition, since maintenance personnel can use tablets for on-site plant operations, their mobile task efficiency can be improved.

High-reliability web server

The TOSDIC VS stores a plant’s operating data in databases on a web server. Since the web server is the cornerstone of a process control system, it is designed with dual redundancy to achieve high reliability.

Client terminals hardly dependent on their performance or the operating system used

Since client terminals use a web browser, remote monitoring and operation are hardly affected by their performance or the operating system used. Therefore, tablets can be used as client terminals.

Web-based monitoring and remote operation system

Environment suitable for ICE

ICE considerations

In the field of instrumentation and control engineering (ICE), instrumentation loop diagrams have been conventionally created as a basis for required specifications. On the other hand, most modern DCS controllers are compliant with the IEC 61131-3 standard that deals with the programming languages of DCS control programs. However, since descriptions of these control programs are very different from loop diagrams, it has been a burden for DCS engineers to maintain both control programs and loop diagrams. The nV-Tool allows you to customize the symbols of IEC 61131-3 functional blocks. The nv-Tool supports custom-made symbols for field devices and instrument balloons, which can be attached to any IEC 61131-3 functional blocks. You can download and monitor instrumentation loop diagrams via these symbols.

PLCs for sub-stations

A process control system uses not only DCS controllers but also programmable logic controllers (PLCs) for sub-stations.
The nV-Tool supports a ladder language for programming PLCs, allowing a single environment to support the development and maintenance of control programs for both DCS controllers and PLCs.

Compliant with the IEC 61131-3 standard

IEC 61131-3 is an international standard that deals with control programming languages and basic software architecture. It supports four programming languages:
Ladder diagram (LD)
Functional block diagram (FBD)
Sequential function chart (SFC)
Structured text (ST)

ICE-oriented nV-Tool

Cloud-based engineering environment management

Anytime-anywhere engineering

Implemented in the cloud, the engineering environment using Meister nV-Tools Cloud supports the monitoring of the typeL as well as program reference and downloading.

Pre-verification via simulation

Examples of utilizing controller and computer functions

Utilization of controller function:Model-Driven PID

Model-Driven PID is a type of IMC (Internal Model Control) algorism developed by TOSHIBA. Compared with PI-D, the merits of MD-PID are to provide optimal control for

  • long dead time process.
  • disturbance as well as set point changes.
  • various process dynamics.
