Programmable Indicating Controller YS1700

Features

• Excellent legibility thanks to a  full-dot color LCD: High visibility of the display screen is ensured even in direct sunlight in the early morning and late afternoon. The user can freely access a desired operation display from meter, trend display, bar graph, alarm, and event displays. All parameters can be set via the front panel display.
• Function block programming: Besides the text programming compatible with earlier models, the YS1700 offers the new GUI-based programming method, function block program- ming. The optional YSS1000 Setting Software for YS1000 Series is used to develop user programs.
• Large programming capacity: Program capacity is 1000 steps for a text program, and 400 modules for a function block program.
• More powerful control and calculation functions: IEEE754- format four-byte floating-point calculations enable actual values to be used in calculations. More than a hundred types of calculation modules are featured, including exponential and logarithmic functions, temperature compensation, and pressure compensation.
• Function selection mode (needs no programming): The multi-function controller mode allows control to be selected from frequently used functions (single-loop, cascade, or selector control) without programming. Function assign- ments to digital and analog inputs/outputs (DIs, DOs, AIs, and AOs) can be determined by parameter settings.
• Expandable I/O: The basic type with expandable I/O has eight analog inputs, four analog outputs, ten digital inputs or ten digital outputs (total fourteen digital inputs and outputs).
• Fail-safe: Thanks to dual CPU (one for control and one for display), display and manual operations are enabled even during a failure of either CPU. The hard manual circuit incor- porated independently from the digital circuits enables the controller output to be adjusted manually during a failure of a digital circuit including both CPUs. (The hard manual circuit is not incorporated when the /NHM option is specified.)
• Nonvolatile memory for memory backup: No battery or capacitor is used for memory backup, facilitating maintenance.
• AC/DC dual power supply with wide operating voltage range to ensure stability against supply voltage fluctuations: Can be driven by either an AC (100 V) or DC (24 V) power supply. Furthermore, the DC power supply enables receiving power without polarity. (Must be specified upon ordering if using a 220 V AC power supply.)
• 250 mm depth (for basic types only)
• Dust- and splash-proof IP54 faceplate (for basic type only)
• CE Mark (for basic type and YS100 compliant type only)
• FM Nonincendive explosion protection (optional for basic type only)
• Communication (optional) - Ethernet (Modbus/TCP; for basic type only) - RS485 (PC Link, Modbus, Peer-to-Peer communication, and YS protocol; unavailable for YS80 internal unit-compatible type) - DCS-LCS communication
• Compatibility with YS100 Series: Setting and control operations can be done with the same feel. For basic-type cases, terminal-to-terminal pitches differ but the signal-to-terminal arrangement is almost the same.

Three connection modes

Connection modes: USB, Ethernet or RS485
When connecting via RS485 or Ethernet, a communication option is required on the main unit.

Full set of computation functions

• Supports parameter setting for all YS1000 models

• Support for YS1700 custom programming.

  • Calculations done using Engineering units and Floating point math.

  • Includes over one-hundred computation modules for exponents,
    logarithms, temperature/pressure correction, and other operations.

  • Function blocks (sub-programs) can be saved and reused.

Password protection function

Passwords can be assigned to user programs to prevent unauthorized access to proprietary programs.
A password on the main unit prevents unexpected changes in the engineering parameters.

Control Output Backup Function

The control output backup function comes standard with YS1000 series controllers (YS1700 and YS1500) and the Manual Station for MV Setting (YS1360).

Dual CPU

With dual-CPU construction (main CPU and display CPU), manual control capability and display continues even if an abnormality occurs on one of the CPUs. If controller self-diagnostics detects a control circuit failure, the controller can suspend analog/digital output, switch to manual mode and allow manual control by operator.

Manual operation-"hard manual" Independent manual override is built into the control circuits, ensuring that control output can continue even when a control circuit including the CPU experiences a problem. *Comes standard with YS1700-1xx, YS1500-1xx, YS1360-1xx

Battery free memory backup

Nonvolatile memory is used for memory backup. Service life is improved because no batteries, backup capacitors, or other components are used.

AC/DC power supply resists powerline fluctuations

The AC/DC (100 V /24 V ) power supply powers the instrument to provide consistent performance.Also accepts DC power regardless of polarity (specify 220 V power supply when ordering).

Improved basic control performance

The YS1000 series achieves higher performance than previous models (YS100 series).

• I/O accuracy
  Voltage input accuracy: ±0.2% ⇒ ±0.1%
  Voltage output accuracy: ±0.3% ⇒ ±0.1%
  Current output accuracy: ±1.0% ⇒ ±0.2%
• Internal data resolution of the I/O signal: 1/1000 ⇒ 1/10000
• Internal computation resolution of PID and other computations: 1/4096 ⇒ 1/65536

Controller online replacement function (portable manual station)

Use the YS110 portable manual station when exchanging or performing maintenance on a controller. You can switch to the spare controller without interrupting the control output.

Front panel conforms to the IP54 waterproof standard

Tougher environmental resistance.

Ethernet : Available to the YS1000 basic type. Modbus/TCP server function (one connection).

Communication with PLC

Connections are enabled using the FA-M3' s UT link module and the RS485 communication function. No programming is necessary to exchange data between the instrument and the FA-M3.

External AI: 3 inputs External AO: 1 outputs External DI: 4 points External DO: 4 points

Note: An interface for the additional Expandable I/O cannot be added after delivery. If there is a possibility that extra input/outputs will be needed, we recommend that you start with the basic model (with expansion I/O).
 

Communication with CENTUM

As with previous models, communication with Yokogawa's DCS (CENTUM) is supported. This is ideal for DCS backup in chemical plants and other applications requiring extreamly high reliability.

Applicable Models: YS1700,YS1500,YS1350,and YS1360

Peer-to-peer communication function

With peer-to-peer communication, up to 32 YS1700 can be connected interchangeably. Four of the connected instruments can each output 4 points of analog data and 16 points of status data.
This makes data exchange and I/O sharing possible since all instruments under peer-to-peer communications can read all data (16 analog and 64 status data).

Control Function

Self-tuning (STC)
Simplifies tuning when starting up or changing the process unit under control.

Flexible DI/DO
The YS1700/YS1500’s six DI/DO terminals can be used for both input and output.
