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.

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.

Overview:
  • 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.
Overview:

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.

Overview:
  • 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)
Overview:

Floating-point format calculations have enabled physical quantities (in engineering units) to be used in calculations.

Overview:

PID is an acronym for proportional band, integral and derivative. This control action allows a measurement (process variable) to be controlled at a desired set point by continuously adjusting a control output. These control parameters act on the error or deviation between set point and process variable.

Overview:

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.

Overview:

Most SLPC and YS170 controllers in the field contain a custom program stored on an EPROM in the case of the SLPC and in NVRAM in the case of the YS170. When upgrading from an SLPC or YS170 to a YS1700, it is necessary to either rewrite the program in YS1700 language or convert the program from SLPC or YS170.

Overview:

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.

Overview:

The power plant for a small town has a single, coal fired boiler controlled by Bailey SLC controllers. Concerned about support issues for the aging controllers, the power plant initiated a control upgrade project.

Industrias:
Overview:

YS1000 Series instruments can accept ONE direct input when a signal conditioning option is specified. The direct input replaces one of the non-isolated 4 to 20mADC (using a 250Ω shunt resistor) or 1 to 5VDC inputs. YS1700 can accept five analog inputs. YS1500 can accept four and YS1310, YS1350, YS1360 can accept two analog inputs. In all cases, one input can be signal conditioned.

Overview:

The boiler combustion control system is designed to maintain a proper air/fuel mixture under varying load conditions and within safe limits. The system should provide nearly complete fuel combustion as efficiently as possible. Discussions here are limited to oil and/or natural gas fired industrial boilers. 

Overview:

Steam drum level control is necessary to add makeup water as steam is delivered into the header and to the associated process equipment. The system should control the drum level at a specific set point while compensating for varying steam demands and drum pressures. For a given volume of steam and blowdown leaving the steam drum, an equal amount of water should replace that inventory.

Overview:

I purchased a YS1500/YS1700 without communications and now realize I need serial and/or Ethernet capabilities.  Is this possible?

It is not possible to add the Ethernet (/A34) option to the YS1500/YS1700 controllers.  However it is possible to add RS-485 (/A31) or DCS-LCS (/A32) communications.  The controller has to be returned to Yokogawa for this retrofit. Contact our service department at 800-524-7378 for more information.

Overview:

The software can be downloaded from this link on the Yokogawa website.  The software is free of charge.   If your controller has the /A34 option, then you can do configuration over Ethernet.  If your controller does not have the /A34 Ethernet option, you will need to purchase a programming cable that is USB to an RJ11 connector which plugs into the front of the controller (behind lift up face plate).
