YS1700 Programmable Indicating Controller
The YS1700 Programmable Indicating Controller can be tailored for various applications by running a user program, and offers high reliability thanks to Yokogawa's proprietary technology, user friendliness, and expandability. Standard models are smaller and lighter than earlier series, requiring less space for installation, and are compliant with international safety standards including the CE Mark and FM nonincendive (optional) approvals. For easy replacement of earlier controllers, models requiring the same panel cutout dimensions and depth as those of earlier models are also offered.
- 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.

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.
| Functions/ Failure area |
Main CPU fail | Display CPU fail | All CPU and Control Circuit |
|---|---|---|---|
| Control with "Hard manual" | X | X | X |
| Manual operation with front keys | X | X | N/A |
| Display for PV and SV | X | X | N/A |
| Control algorithm | stop | stop | stop |
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).

Powerful and Flexible
Ethernet support
The instrument can be easily connected to DAQWORX, SMARTDAC+, general-purpose SCADA, and OPC servers via Ethernet (Modbus/TCP).
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.
The YS1000 can also be connected to PLCs of various manufacturers via the Modbus communication protocol.
Expandable I/O
Additional I/O can be added by selecting the YS1700 basic model (with Expandable I/O). The total number of input/outputs points with the main unit and Expandable I/O are 8 analog inputs, 4 analog outputs, and 14 DI/DO.
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).
| Maximum no. of connections | 32 |
|---|---|
| No. of receiving units | 32 |
| No. of transmitting units | 4 |
| Transmitted data | 4 analog and 16 status data per transmitting YS1700 |
| Communication interval | 200 ms average (not synchronized to the control computation interval) |
Control Function
Self-tuning (STC)
Simplifies tuning when starting up or changing the process unit under control.
Setpoint filter (SVF)
Can optimize tracking with changes in set-points. Also can maintain optimum responsiveness to disturbances.
Flexible DI/DO
The YS1700/YS1500’s six DI/DO terminals can be used for both input and output.
Programmable function key
With a user program, the program function key (PF key) on the instrument’s front panel can be used as an ON/OFF switch for self-tuning, or as a Start button for sequence operation.
Compatibility
- In the YS170 and SLPC, single-element control needs to be configured within the user program.
- The YS1700, however, offers the primary direct mode so that the user program can switch on and off single-element control by changing a parameter.
For safe and efficient operation, the quality of feedwater, steam, and condensate in boiler plants must be controlled and maintained in the most favorable conditions.
- Compressor start and stop
The inlet valve and blow-off valve are controlled efficiently. - During steady-state operation
The inlet valve is controlled to regulate the blow-off flow rate of the compressed air. (Flow control)
- Effeciently controls the inlet valve and blow-off valve when the compressor starts and stops.
- During steady operation, controls the inlet valve so that the amount of discharged compressed air becomes constant (flow control)
- Surging: Load decreases, the amount of discharge flow and pressure drop, and a limit is exceeded, possibly destroying the compressor.
To technology in iron & steel industry is continuously improved to obtain the best possible performance. The improved plant performance gives rise to the higher quality improvement and lower cost, and simultaneously environmental friendly plant operation.
Continuous technology improvement is ongoing in the pulp & paper industry to obtain the best possible performance. The improved plant performance translates to the higher quality improvement and lower cost, and simultaneously environmental friendly plant operation.
In district heating/cooling and other systems, signals from flow meters can undergo temperature compensation in a totalizer to measure usage of warm water and other quantities. Here we give an example of how to perform temperature compensation of flow using the YS1700 Single Loop Controller in place of a dedicated totalizer.
Automated control of industrial boilers is an excellent application for YS1700 microprocessor-based loop controllers. These instruments can be programmed to perform the operations of plant master, boiler master, fuel and air control with oxygen trim and drum level/feedwater control.
