Smart Controller_PosMaster

PosMaster was developed with POSCO DX’s unique know-how accumulated through the automation of steel-making and manufacturing processes and digitalization of industrial field systems. It is an IPC-based smart controller that integrates PLC and HMI, which are required by automation systems in the industrial field.

Function

  • PLC

    Programmable Logic Controller

    International standard programming and flexible configuration of I/O interface according to the standard communication protocol.

  • HMI

    Human Machine Interface

    Visualizes a variety of data to create the type of HMI that users want.

  • P/C

    Process Computer

    Sends and receives data with PLC/HMI of factory automation level 1 and MES of level 3. Also, performs process control and equation modeling.

  • AI

    Artificial Intelligence

    Runs AI/big data models trained in PosFrame or on-premise learning systems in conjunction with PLC.

  • DAQ

    Data Acquisition

    Sends data collected through various protocols to PosFrame or analytics server.

Configuration

PosMaster consists of PosMaster-PLC and PosMaster-HMI and is implemented in modular architecture on the same platform. PLC and HMI of PosMaster process high-capacity I/O data at high speed and support stable system operation with redundancy.

PosMaster-PLC

Adopted high-performance IPC with a multi-core CPU to support various functions needed for automation and edge computing. Moreover, it can use the same language as the existing PLC by conforming to the international industry standard (IEC61131-3).

PosMaster-PLC
Features
  1. Supports interface to HMI server and L2.
  2. Supports remote I/O and various Fieldbus communications.
  3. Implementation of PLC redundancy system. (maximum transfer time of less than 100ms)
PosMaster-HMI

Developed with a proven open source (EPICS), and provides a user-friendly display, API-based functional integration, data acquisition, and trend alarm function.

  • HMI production tools
    • Widgets in various reusable formats.
    • Alarm screens configurable with various conditions.
    • Historical trend screen for operation analysis.
  • Collection, storage, and display functions
    • Accurate collection and storage of large-scale time series data.
    • Interface to wide range of systems.
  • Server redundancy and reporting
    • HMI server and network redundancy.
    • Daily, weekly, and monthly reporting.

Features

  • Optimal Smart Factory environment

    The IPC-based, high-speed data processing environment increases the utilization of Smart Factory and allows integrated operation of various analysis packages and models that were not available in existing PLCs. Moreover, it provides an architecture that facilitates the interface with new technologies such as IoT, AI, and digital twin.

  • Efficient cost-saving

    A flexible software product based on open source that can be embedded in any hardware. Multiple (up to 4) controllers can be configured to a CPU to save the cost of additional hardware.

  • Specialized services based on a wide range of references

    Provides specialized libraries based on extensive experience in process control of steel making and reduces the engineering period. Moreover, it provides remote I/O and various field communications that are not maker dependent to assure universal application.

  • Stable O&M service

    Superior security with Linux OS that is not vulnerable to Windows-specific viruses. Easy prior verification for program modifications with built-in simulation, trend, and visualization functions.
