    Operation Views - Ease and Continuity

    Four types of operation views, Short Trend, Digital Display, Bargraph and Dual Bargraph, are available to suit various process applications, designed for the sense of ease and continuity for the operators who have been familiar with existing controllers.

     
    Short Trend   Bargraph
    Short Trend   Bargraph
      Loop control parameters (PV, SP and MV) are indicated with bargraphs and on the digital displays. Specific internal computation values can be assigned to FN1...FN4 and indicated on the digital display.
    200 samples for four variables per loop are plotted on the chart (total 8 variables). Sampling interval is selectable between 1 second and 60 minutes.
    Max. 400 samples of stored trend data can be exported to a PC in CSV format (SC200/210).
       
         
    Digital Display   Dual Bargraph
    Digital Display   Dual Bargraph
    Loop control parameters (PV, SP and MV) are indicated on the digital displays. Specific internal computation values can be assigned to FN1...FN4 and indicated also on the digital displays. An error message appears in case of an error.   Loop control parameters (PV, SP and MV) for two loops are indicated with bargraphs and on the digital displays. Touching 1st/2nd button switches the loop to be manually controlled.

    Engineering Views - Versatility and Flexibility

    PID parameter setting, display and operation setting and function block setting are accessible respectively at Tuning, Configuration and Programming views.

     
    Tuning   Programming
    Tuning   Programming
    PID parameters, PB (proportional band), Ti (integral time) and Td (derivative time), are set on the Tuning View.
    Auto-tuning is also available in this view. Bargraph and digital displays for the loop parameters and the short trend graph are displayed at once.
      Function block parameters are set on the Programming View by simulating operations of the PU-2A Programming Unit. The SFEW3E Loop Configuration Builder software for Windows PC is also available for ease of setting all advanced function block configurations.

      User's selected parameters are listed, monitored and changed.   I/O values and error status of all field terminal blocks are displayed.
       
    Display and operation of the Controller are thoroughly adjustable to enhance the user's comfort.    
             

  • DCS in Instrument Format 
    - Advanced Computation and Sequential Control Functions

    The control and computation functions are achieved by combining a wide variety of basic to advanced function blocks, which are normally found only in DCS systems. 2 PID blocks, 48 computation blocks and 12 sequential control blocks (1068 commands) are available for all versions of the SC Series, applicable to a wide range of application fields.

  • Excellent Expandability - Peer-to-peer and Host Communication

         

    The SC200/SC210 has Modbus (Ethernet TCP/IP or RS-485 RTU) which enables easy connection to logging or SCADA systems on a host PC for supervising and controlling the local I/O data. 

    In addition, the RS-485 'NestBus' enables peer-to-peer communication with other controllers and I/O devices for flexibility of I/O points.

    Chemical Injection Control   Reactor Temperature Control
    The SC100 controls two flow loops for water and injected chemical. The chemical flow is controlled in a constant ratio against the water flow. Other signals from pH and conductivity analyzers can be monitored at once.   An example of temperature control in a batch control reactor. The reactor temperature control loop is connected in cascade to the hot water control loop in the hot water tank. The secondary loop controller controls the valves for hot water and steam.
         

  • High Reliability - For Demanding Process Use

    Control, display and I/O functions are managed by independent CPUs for enhanced security and reliability. 

    The built-in manual loader (SC110/210 option) can be controlled independently even in case of a failure of the main controller module, which can be replaced easily while the backup control is maintained. 

           

     

    The main module can be disconnected from the backup module and extracted with the front display. 

      High Reliability

    The front blue LEDs are connected to the backup module, while the front UP/DOWN control buttons are connected to both main and backup in parallel.

     

    The backup module can be powered independently from that of the main module for further reliability.

     
         
         

    When the control is switched to the backup module either manually or automatically, the MV 2 selector SW is set from Main to Backup.

    *Independent power supply is optional. Model: SML SC200 SC200 SC210 SC210 SC200 SC200
     

    Transition of output level is smooth as the backup module has been continuously tracking the control module output in normal status.

     

    A preset value can be provided also as output in the backup mode.

     

    The control module output can be tracked either manually or automatically to that of the backup before switching back to the normal mode.
