About an Electronic Manual

User’s manuals for YS1000 are available on the following web site:
www.yokogawa.com/ns/ys/im/
You need Adobe Reader 7.0 or later (but the latest version is
recommended) installed on the computer in order to open and read
the manuals.

*1 The instrument has a built-in terminating resistor, which can be

selected for use by setting the relevant parameter. If a terminating
resistor is used in another device at the termination of the same
communication system, an external terminating resistor needs to
be provided to match the terminating resistance of the YS1000’s
built-in terminating resistor.

Introduction to Functions

The YS1000 series is a series of single-loop controllers to meet the demands of users’ consistently advancing and diversifying
needs. It is capable of the flexible control computation required for process control.

Features

• Color LCD display
The monitoring and operation display is provided in color, and input and output values, various constants, and incorporated

control functions can be set freely using key switches on the front panel. The monitoring displays include LOOP Display,
TREND Display, ALARM Display, and METER Display which provides information in much the same way as analog meters.

• Failsafe function
Two CPUs are configured to provide manual operations and displays even if one of the CPUs becomes faulty. Moreover, be-

cause the instrument incorporates a hard manual circuit independent of the digital circuit, it can continue to generate manipu­lated output variables even if the digital circuit that includes the CPUs fails.

• AC/DC-common power supply with wide operating voltage range.
The instrument can be powered by either AC (100 V AC) or DC (24 V DC).

• The front panel is dust- and water-proof (conforming to IP54).

• Abundant communication functions
The instrument can incorporate Ethernet (Modbus/TCP) communication, serial communication (Modbus, PC-link, and YS

protocol), and DCS-LCS communication.

• Control functions and abundant computation functions
The instrument is capable of single-loop, cascade, selector, and programmable control functions.
It can also perform computations such as the four arithmetic operations, logic computation, exponent, logarithm, temperature

compensation, pressure correction, etc. and peer-to-peer communication. (Optional YSS1000 Setting Software is required.)

Introduction to Functions

• Number of I/O points
Use of YS1700’s expandable I/O terminal allows the use of a maximum of eight analog inputs, a maximum of four analog

outputs, and a maximum of 14 DIOs.

Definition of Terms

• PV: Process variable input from process

• SV: Setpoint regarded as a control target

• MV: Manipulated variable for operating control elements such as valves.

• PID control: Control system based on action which combined three elements: proportional (P) action, integral (I) action, and
derivative (D) action.

• M mode: Mode in which manipulated output variables are operated manually.

• A mode: Mode in which MV is automatically controlled based on YS1000’s setpoint

• C mode: Mode in which MV is controlled based on an external setpoint

• Multi-function mode: Modes of the three preinstalled functions (single-loop mode, cascade mode, and selector mode)

• Programmable mode: Mode in which input/output or control computation is programmed

• User program: A program created using the YSS1000 Setting Software (available as an option)

Overview of Display Switching and Operation Keys

The YS1000 has the following three display groups:

(1) Operation Display Group

This group has a LOOP Display which allows operation mode switching during control operation, SV setting, and MV opera-

tion; a TREND Display which displays the trends of PV, SV, and MV; an ALARM Display which displays detailed alarm infor-
mation; a LOOP Display which displays two loops simultaneously (operation is on a loop basis); and a METER Display which
displays PV, SV, and MV on a meter scale using a pointer.

(2) Tuning Display Group

This group has a display for setting and displaying control parameters such as PID, and a display for monitoring input/output

signals.

(3) Engineering Display Group

This group has a display for setting up functions as a controller, a display for setting and displaying various registers and vari-

ous tables, a display for setting input specifications and a password setting display.

Monitoring and Control of Regular Operations (Operation Display)

Operating the LOOP Display

This section describes keystrokes for performing various settings and operations on the LOOP Display.

(1) Switching the operation mode

M mode key: Switches the operation mode to manual control (M mode).
A mode key: Switches the operation mode to automatic control (A mode).
C mode key: Switches the operation mode to cascade setting automatic control (C mode).

Moreover, the LED inside the operation mode key corresponding to the current operation mode lights up.

Note

Ifacascadeinputsignalis−6.3%orlessor106.3%ormore,theoperationmodecannotbeswitchedtoCmode.

► Forswitchingtheoperationmode:see“SwitchingofOperationModes”inthismanual.

(2) SV setting operation

The SV setting key changes the setpoint (SV).

This key is enabled when the operation mode is in the A or M mode.

SV increase key: Increases an SV value.
SV decrease key: Decreases an SV value.

(3) MV operation

The MV operation key is used to manually operate a manipulated output variable (MV). This key is enabled when the opera-

tion mode is in the M mode.

MV increase key: Increases an MV value.
MV decrease key: Decreases an MV value.

Moreover, pressing an MV operation key with the

increase/decrease speed.

SHIFT

(fast-change key/SHIFT key) held down accelerates the MV-value

(4) PF key functions

The PF key functions are different in the multi-function mode and the programmable mode.

Multi-functionmode:

The PF key function is set on the Function Setting Display 3 (CONFIG 3). There are the following two parameter designations:

(1) No function: The PF key does not function.
(2) STC ON/OFF: The PF key switches STC operation ON/OFF.
If STC ON/OFF is specified, when STC is ON the LED inside the PF key lights up.

Programmable mode:

The PF key function is defined by user programs then used. The LED in the PF key can be turned ON/OFF by the user pro-

grams.

For cascade control, selector control, or dual-loop control, the loop 1 can be operated on the LOOP 1 Display, while the loop 2
can be operated on the LOOP 2 Display.

(4) PV meter scale

Main scale marks,

(5)

subscale marks

PV, SV, and MV digital values are displayed here.

The PV meter scale displays main and subscale marks, a numerical scale, a scale factor, and engineering units.
The main scale marks and subscale marks are determined by setting the variables to the 0% value of scale (SCL) and to

the 100% value of scale (SCH), which causes the scale to be automatically divided into divisions based on those values.
The scale range is clearly represented in the range of the number of numerical scale digits using the

(6) Scale factor

power of 10 (× 10n). It is possible to set the value of the power, however it can also be automatically
determined from the 0% value of scale (SCL) and 100% value of scale (SCH).
The numerical scale is automatically determined from the 0% value of scale (SCL) and 100% value of

(7) Numerical scale

scale (SCH), and is displayed centered and to the right of the main scale marks. The number of digits to
be displayed is three (or four digits if there is no decimal point).

(8) PV pointer

(9) SV pointer

A PV value is indicated by two pointers (at the left and right sides of the scale). The pointer display
moves up and down with a resolution of 0.5%.

An SV value is indicated with a pointer. The pointer display moves up and down with a resolution of 0.5%.

PH values (high limit alarm setpoints for PV) and PL values (low limit alarm setpoints for PV) are indicated
with triangular pointers, while HH values (high-high limit alarm setpoints for PV) and LL values (low-low limit
alarm setpoints for PV) are indicated with pointers which are overlapped pairs of triangles.
Scale marks are displayed on the MV meter scale. The mark at the far left is the 0% position and the
mark at the far right is the 100% position. Each scale division is 5%.
MV values are indicated with a pointer. Since the scale’s full scale is 80 dots (100%), the MV pointer
increases and decreases in a resolution of 1.25%.
MH values (high limit setpoints of MV) and ML values (low limit setpoints of MV) are indicated with
triangular pointers.
