Chapter 1. PRODUCT OUTLINE

1 - 1 Features

The DCP551 is a general purpose single-loop control programmer for controlling temperature, pressure, flow rate

and other parameters. The program provides a total of 99 patterns and up to 99 segments can be set for each

pattern. Note, however, that the maximum number of segments is 2000 or less and that the maximum number of

subfunctions for setting events is 4000 or less.

● High accuracy in multi-range inputs

Featuring a multi-range format, the user can select thermocouple, resistance

temperature detector, DC voltage or DC current. Accuracy is ±0.1% FS ±1 digit,

the sampling cycles is 0.1 sec and some model numbers allow PV2 channel

switching.

● Multi-control output types

Selection at setup allows the user to choose from among current proportional

setting output, current proportional output, voltage time proportional output and

open collector time proportional output.

● Multi-communications

Selection at setup enables the user to switch between RS-485 and RS-232C on the

rear panel terminal base.

At setup it is also possible to switch the communications port from the rear panel

terminal base to the front panel loader jack. A special cable is required to use to

terminal base on the front panel.

● Improved PLC support

The programmer is equipped with 16 external switch inputs and 16 event outputs

for flexible support of PLC based automatic systems.

● Simple operation

The optional plug-in memory card makes it easy to achieve program and

parameter settings for later reuse. Also, the optional smart loader package allows

you to make program and parameter settings from a PC.

4 - 1 Precautions on Wiring

4-1

CAUTION

Connect the controller as specified using designated cables and connection procedures. Failure to heed this caution may lead to electric shock, fire or malfunction.

Make sure that wire scraps, chips or water do not enter inside the case of the controller. Failure to heed this caution may lead to fire or malfunction.

Current applied to current input terminals

(55), (56) and (58), (59)

must meet the specified range. Failure to heed this caution may lead to fire or equipment breakdown.

All terminal screws shall be tightened to specified torque. Improperly tightened screws may lead to electric shock or fire.

Do not use unused terminals on the instrument as relay terminals for other equipment. Failure to heed this caution may lead to electric shock, fire or equipment breakdown.

If there is a risk of a power surge caused by lightning, use a surge protector to prevent fire or device failure.

Be careful not to allow crimp terminal lugs to touch adjacent terminals.

WARNING

Connect the FG terminal to ground with a ground resistance of maximum 100Ω before connecting other equipment and external control circuits. Failure to do so may cause electric shock or fire.

Before removing, mounting, or wiring this module, be sure to turn off the power to the module and all connected devices. Doing so may result in an electric shock.

Do not touch a live part such as a power terminal. This may result in electric shock.

Page 36

4-2

Handling Precautions

• Before connecting the lines, verify the model number and terminal numbers on the label affixed to the side panel of the DCP551. After completing, always double check to ensure all wiring has been performed correctly before turning on the power.

• The I/O signal lines and the communications lines shall maintain at least 50cm between them and the power supply line and power supply cables. Do not route these cables through the same conduit or duct.

• Make sure that no crimp-style solderless wire connectors are touching an adjacent terminal or connector.

• When connecting a thermocouple input of the DCP551 to another instrument, make sure the instrument’s input impedance totals at least 1MΩ. If less than 1MΩ, the DCP551 may not be able to detect sensor disconnection.

• Cautions when using data input devices in combination Input of the DCP551 input or output (connected in parallel for input) to an A/D converter, analog scanner, etc., may cause dispersion of the read data. To prevent such occurrence, take one of the following corrective measures.

(1) Use a low-speed integral A/D converter.

(2) Insert an isolator with no switching power supply between the

DCP551 and the A/D converter.

(3) Perform averaging with a personal computer when the data is read.

(4) If the device permits, insert an input filter.

• Devices and systems to be connected to this must have the basic insullation sufficient to with stand the maximam operating voltage levels of the power supply and input/output parts.

Chapter 4. WIRING

Page 37

4 - 2 Recommended Cables

To perform thermocouple input, connect a thermocouple element to the terminals. When the wiring distance is long

or when connecting the thermocouple without the element to the terminals, connect via shielded compensating lead

wires.

NOTE

• For I/O other than thermocouple, use JCS4364 instrument cable or equivalent

(is commonly called twisted shielded cable for instrument use).

The following cable are recommended.

• A shielded multicore microphone cord (MVVS) may be used, if electromagnetic

induction is comparatively low.

● Internal circuit diagram of the DCP551 connecting external switch input

Handling Precautions

• The inputs of the DCP551 unit are provided with a built-in power supply (open voltage type, 8.5Vdc). Always use no-voltage contacts externally.

• For the no-voltage contacts, use gold contacts or other relays that switch on small currents. Other types of relay contacts may not switch. Use contacts that have ample margin over the minimum switching capacity with respect to the current and open voltage ratings of contacts provided on the DCP551.

• If using semiconductors (open collectors, etc.) as no-voltage contacts, use one that maintains a potential of no more than 2V across the contacts when actuated, and a leakage current of no more than 0.1mA when shut off.

• The digital inputs (remote switch inputs) of all SDC40 and SDC10 series units can be connected in parallel. If connecting them in parallel to another instrument, carefully check the requirements of the other instrument before proceeding.

• Do not connect SDC20/21, SDC30/31 series in parallel. Doing so may cause the external switch input to malfunction.

• Common terminals (12) and (41) of the external switch input are connected internally.

5-2

■ Pattern

Three systems for selecting programs are provided: RAMP-X, RAMP-T and

RAMP-E. The first segment of each program is always RAMP-X, but the other

segments can be any system and all three types can be used in one program.

● RAMP-X system

This system, sets a segment of a pattern using SP and time, is called RAMP-X.

SP setting : within the upper and lower SP limiter range

Time setting : 0 hours 00 minutes to 500 hours 00 minutes

0 minutes 00 seconds to 500 minutes 00 seconds or

0.0 seconds to 3000.0 seconds (Time units are selected using the C62 setup data setting.)

SP is a point on the elapsed time axis in the current segment, which is a straight

line connecting the start point, the SP set value in the previous segment, and the

end point, the SP set value in the current segment. Segments are classified as

follows.

•Rising RAMP (or rising slope)

Previous segment SP setting < current segment SP setting

•Falling RAMP (or descending slope)

Previous segment SP setting > current segment SP setting

•SOAK (soaking)

Previous segment SP setting = current segment SP setting

The start and end points of the first segment are also the SOAK segment of the SP

set value for the first segment.

SP calculation (other than first segment)

SP = (current segment SP set value – previous segment SP set value)

× (current segment elapsed time ÷ current segment time setting)

+ previous segment SP setting.

Chapter 5. FUNCTIONS

Time setting of current segment

SP set value of previous segment

Page 55

5-3

● RAMP-T system (θsetting)

In the RAMP-T system, a segment is set using SP and ramp θ(theta).

SP setting : within the upper and lower SP limiter range

setting : 1 to 10000 (SPU/hour, SPU/min, SPU/sec)

(Time units are selected using the C62 setup data setting.)

SP is a point on the elapsed time axis in the current segment which is an extended

straight line, the ramp set value of the current segment when the SP set value in

the previous segment is the start point.

The end point is the point where this line reaches the SP setpoint of the current

segment. Note that the RAMP-T system cannot be used in the first segment.

SP calculation: SP = θset value × segment elapsed time + previous segment SP.

● RAMP-E system (∆ SP setting)

In the RAMP-E system, segments are set using SP and ∆ SP (digital SP) for each

external switch input pulse.

SP setting : within the upper and lower SP limiter range ∆ SP setting: 1 to 10000 SPU

The start point is the SP set value in the previous segment.

SP is a value resulting from adding a multiple of the external switch input count to

the SP set value when the SP in the previous segment is the start point.

The segment ends when this SP reaches the SP setting in the current segment and

the current segment SP is more than the previous segment SP or when current

segment SP is less than the previous segment SP.

SP calculation: when current segment SP is more than the previous segment SP, SP = ∆ SP set value × external switch input count + the previous segment SP.

When current segment SP is less than the previous segment SP, SP = – (∆ SP set value × exernal switch input count) + the previous segment SP.

• External switch for pulse input requires 1: RAMP-E using a setup data setting

between C71 to C74.

• The pulse input interval time can be checked by setting event type 93 in the

event. Event type 93 is RAMP-E time monitored during a period of 0.0 to

3000.0 seconds.

Even when a setting is exceeded and there is no pulse input, the event remains

on.

Chapter 5. FUNCTIONS

Page 57

5-5

■ Events

The event configuration data setting allows event types to be set for event outputs

1 to 16.

Events are of the following four types: time event, PV event, code event and mode

event. Settings are divided into two types of events: segment events and

instrument event.

• Segment events are used to set the event operating point in a program setting

and makes it possible to set different set values in different segments. But in the

constant value control mode segment events are off.

• Instrument events are used to set events that do not require an event operating

point or set the event operating point in the event configuration setting. It

performs operations that are shared by all program operations and constant

value control.

● Time events

The On Time or both the On and Off Time can be set by event number and

segment. Output on/off duration are as shown below.

NOTE

•The On Time is indicated by the length of the line from the start of the

segment until the upturned arrow.

•The Off Time is indicated by the length of the line from the start of the

segment until the downturned arrow.

• When the On Time is less than the off time, the output is on from the on time

until the off time.

(See segments 1, 6 and 7 in the figure.)

• When only an on setting is made, the output stays on until the end of the

segment. (See segments 2 and 5 in the figure.)

• The output is off when no On or Off Time has been set.

• An off time cannot be set without setting an on time. (See segment 3B in the

figure.)

• An On Time ≥ Off Time setting cannot be made.

(See segment 3C in the figure.)

• An On Time or Off Time is valid only within a segment and cannot straddle

segments. In the next segment, the On time and Off time set for that segment

are valid. (See segments 4 and 5 in the figure.)

Thus an On Time and Off Time setting made at the end of a RAMP-X segment

are ignored. (Compare segment 9 with the G.SOAK wait in segment 10 in the

figure.)

Note, however, that an On Time or Off Time setting at the end of a RAMP-T

segment is either valid or invalid depending on the computational error.

• When the On Time is set to 0 (no Off Time being set or set to more than 0), the

output goes on when the On Time becomes 0. If the output was on at the end of

the previous segment, it stays on and does not go off momentarily between the

two segments. (See segments 5 and 6 in the figure.)

• The G.SOAK Time is not included in the On and Off Time. (See segment 7.)

Nor is the Wait Time included for a G.SOAK that occupies an entire segment.

• When there is a G.SOAK wait at the start of a segment and the ON Time is set

to 0, the output goes on at start of the G.SOAK wait and the On Time starts as

the G.SOAK wait ends.

The output time = G.SOAK time + (Off Time – On Time) (See segment 10 in

the figure.)

• An On Time and Off Time occurring at the end of a RAMP-X segment are valid

when there is a G.SOAK wait at the end of a segment or as the end state of the

final segment. (See segment 10 in the figure.)

Note, however, that an On Time or Off Time setting at the end of a RAMP-T

segment is either valid or invalid depending on the computational error.

• When there is a G.SOAK at the end of the previous segment, the On Time in

the next segment is ignored if it is set to 0. (See segments 11 and 12 in the

figure.)

Thus the ON = 0 of segment 12 is not output at the end of the set time for

segment 11, but when the G.SOAK wait ends.

• This function can be combined with an event ON delay set using PARA. Delay

works when an event goes from off to on. A delay is not triggered when an On

Time continues across two segments as shown in segments 5 and 6 in the

figure.

● PV event

• Basic specifications

The difference between PV, deviation, absolute value deviation, SP, MV and

PV1-PV2 for each event type is shown on the following pages. The thick lines

show ON and OFF conditions. The upper line indicates ON and the lower line

indicates OFF conditions.

EV indicates the event set value and H indicates the hysteresis value. Outputs in

READY mode are OFF. But normal PV1 upper and lower limit operation and

normal PV2 upper and lower limit operation events run also in the READY

mode.

• Event standby

Standby events operate as described below.

• If the event is in the gray area shown in the figure during a change from

READY to RUN mode or when the power is restored after an outage, the

event operates without a standby. The upturned arrows in the figures indicate

ON while the downturned arrows indicate OFF.

• If the event is outside the gray area shown in the figure during a change

from READY to RUN mode or when the power is restored after an outage, it

remains off until it enters the gray area .

After entering the gray area , the upturned arrows in the figures indicate

ON while the downturned arrows indicate OFF.

A standby event is off in the READY mode.

• Event on delay

The number of the event to be delayed and the delay time can be set regardless

of event type. The delay turns on the output for the duration of the delay when

the event meets the conditions for going from OFF to ON. When this function

is combined with the event standby function, the event on delay operates when

the standby state is cleared.

• Segment event progress

• The output stays OFF until the program reaches a segment with an event.

• The event goes ON or OFF according to the set value of the event.

• Previous settings are valid until segments with other event settings are

reached.

• Previous settings are valid when the program has reached segment number 1

using the cycle function or pattern link function. The output is turned off if

there is no event in segment number 1.

• Other functions

The MV forward/backward event does not operate when the C21 setup data

setting is set to 0 during SP output (programmer function).

Normal PV2 upper and lower limit operation events and PV1-PV2 differential

of upper limit and lower limit events during automatic PV channel switching do

not operate on models with only one PV input channel.

Normal PV1 upper and lower limit operation event and normal PV2 upper and

lower limit operation events operate in the READY mode.

● PV deviation rate event

PV deviation is measured in each sampling cycle set using eventconfiguration

while on/off states are determined by comparing event setting deviation rate PVs.

PV deviation between sampling cycles is ignored. Event on/off switching is

performed according to the sampling cycle. This function can be combined with

event on delay.

● Code event

Several events are used as one group and the number of output points are output

as one parallel code number. Assigning code numbers to event outputs has the

same effect as increasing the number of physical output points.

• Code event

Set event type to code event and set the number of output points (1 to 8) in

auxiliary setting 1. An output code value (0 to 255) can be set for each segment.

A binary coded low-order bit for the set number of output points is output.

The previous setting is valid until the program reaches a segment with a new

setting.

Note, however, that unless a setting is made in the first segment, the program

will assume that a set value of 0 is set in the first segment.

Chapter 5. FUNCTIONS

Example: Setting a code event involving 3 output points in event 3

• Timed code event

This function is a combination of a code event and a time event. The set code

value is output at the set time. The number of settings that can be made in the

first segment is the same as the number of output points. For example, for a 3-

point output up to three settings can be made in the first segment.

Like a time event, a time within the time of the segment is valid and those that

exceed the value are ignored. When the program reaches the start time of the

first segment or a new segment, the set code value is 0 (all points off) until the

set time of the time event.

Chapter 5. FUNCTIONS

Example: Setting a timed code with 3 output points in event 3

The table below shows the output state when a value of 5 is set in segment 2 and set to start at the beginning of the segment, a value of 3 is set to occur 0:10 after the start of segment 2 and a value of 4 is set to occur 0:30 after the start of segment 4.

• Program/segment number event

A program or a binary coded segment number is set in an event type and the

number of output points (1 to 7) is set in auxiliary setting 1. Or a program or a

BCD code of the segment number is set in an event type and the number of

output points (1 to 8) is set in auxiliary setting 1.

A selection, a program designed for a specific operation or a coded segment

number is output. A low-order bit code corresponding to the set number of

output points is output.

• An event on delay can be combined with the code event.

Note, however, that when there are several channel code events, the delay has

to be entered for each channel.

● Mode event

This event goes on or off depending on controller mode, alarm generation and

other states.

It cannot be combined with the event standby function but with the on delay

function. It does not set event set values (operating points) or hysteresis.

• Basic operations

The following types are provided.

RUN + HOLD + END + FAST

Battery voltage drop

The event goes on when the specified instrument state is reached and is off at

other times.

• Alarm

Alarms are of two types: PV range alarm group (alarm code number 01 to 04)

and instrument alarm group (alarm code number 91 to 99 and battery voltage

drop). When the event type is all alarm, the event goes on if one alarm occurs.

When the event type is a PV range alarm, the event goes on if one alarm in the

PV range alarm group goes on.

When the event type is an instrument alarm, the event goes on if one alarm in

the instrument alarm group goes on.

•ADV

When ADV (advance) is executed, the event goes on for 1 second. This

function is valid during on delay.

Chapter 5. FUNCTIONS

Page 68

5-16

■ PID group selection

• ID groups can be selected in two ways: by setting a PID segment or through

automatic PID group switching.

A PID group segment and automatic PID group switching can also be

combined. When a PID group number is set to 0, the setting in the previous

segment is continued.

• In a PID group segment setting a PID group number is set in each segment and

PID parameters are used for calculating the control output. The nine PID groups PID1 to PID9 can be used.

• In automatic PID group switching, the entire SP scale is divided into seven

zones assigning CP-A1 to CP-A6 to each. The PID constants that are used

according to SP values are automatically selected to calculate control output.

The PID group number for each segment specifies A. Seven PID groups from PID-A1 to PID-A7 can be used.

■ Selection of ouput limiter group

• Output limiter group number can be set for each segment to control the lower

limit (OL) and upper limit (OH) of the control output. oL and oH groups 1 to 9

can be used.

• The output limiter can only be specified by segment; automatic selection cannot

be made.

• When the output limiter is set to 0, the setting in the previous segment is

continued.

■ G.SOAK (Guarantee soak)

G.SOAK on/off state, type and G.SOAK width is set by the segment. G.SOAK are

of three types: segment start point, segment end point and the entire segment. G.SOAK time is set using the variable parameter PA46 setting. Any offset

between SP and PV triggers a G.SOAK wait which narrows the distance between

SP and PV to guarantee the segment execution time. G.SOAK operates not only

on SOAK but also on RAMP segments.

Note, however, that in FAST mode a G.SOAK setting does not trigger a G.SOAK

wait.

G.SOAK can be cleared with an external switch input. The following types of clearing conditions can be selected using setup data setting C71 to C74.

(1) G.SOAK is cleared when an external switch contact is set to on or when PV

meets the G.SOAK clearing conditions.

(2) G.SOAK is cleared when an external switch contact is set to on and PV meets

the G.SOAK clearing conditions.

• G.SOAK at start of segment

PV and SP are compared at the beginning of the segment. The segment starts

when the absolute value of the difference continues beyond the G.SOAK time

and becomes narrower than G.SOAK width.

A G.SOAK wait state continues until these conditions are met which is

announced by the flashing of the linear LED on the left of the profile display.

The operating condition is the same as HOLD at the beginning of a segment

(time = 0).

• G.SOAK at end of segment

PV and SP are compared at the end of the segment. The operation in that

segment ends when the absolute value continues beyond the G.SOAK time and

becomes narrower than G.SOAK width.

A G.SOAK wait state continues until these conditions are met which is

announced by the flashing of the linear LED at the center of the profile display.

The operating condition is the same as HOLD at the end of a segment (time =

set segment time).

• G.SOAK for entire segment

PV and SP are compared at across the entire segment. The operation in that

segment continues when the absolute value continues beyond the G.SOAK time

and becomes narrower than G.SOAK width.

A G.SOAK wait state continues until these conditions are met which is

announced by the flashing of the linear LED at the left and the center of the

profile display.

The operating condition is the same as HOLD at the continued time.

■ PV shift

A PV correction value can be set for each segment. PV is PV input value plus PV

bias and PV shift. Note, however, that in the READY mode and the constant value

control mode, PV bias but not PV shift is added to the PV input value.

The setting in the previous segment continues when PV shift is set to “-----”

(nothing).

■ Repeat

Repeat on/off and return destination are set by the segment with the segment

number and repeat count. Operation completes at the end of a segment. If there is a

repeat setting, the program returns to the start of the set destination segment and

operation is resumed from there. This operation is repeated the number of times

specified by the repeat count.

No repeat is performed when the destination segment number is larger than the

current segment number. When the program returns to the first segment, PV is not

started even if a PV start setting has been made.

Handling Precautions

• When repeat operations involve multiple segments and the destination

segment settings overlap, nest or intersect, the repeat operation will become an abnormal eternal loop. Do not make such settings.

• When the current segment does not contain a set value or the value is 0,

executed values for program items (for example, set PV event values or set PID group selection values) that are sequels to settings in a previous segment are the same during the first run and the repeat run.

■ PV start

When a PV start is set in the program setting, a PV start is performed in a normal

RUN operation.

The program looks for the first point where PV and the program pattern SP are

equal (both PV and SP include bias) and starts operation from there. PV starts are

of three kinds: rising PV start that looks for a point where PV and SP are equal on

a rising RAMP, falling PV start that looks for a point where PV and SP are equal

on a falling RAMP and bi-directional PV start that looks for such a point both on

rising and falling RAMPs.

Note, however, that if there is no point where PV and SP are equal, operation

starts from the beginning of segment 1.

When a PV start has been implemented, the event operating point and the time

event time are automatically corrected. This is described in the figure shown below. When PV is at (1) in the figure, a rising PV start or a bi-directional PV start starts from B and a falling PV start starts from C. When PV is at (2) in the figure,

a falling PV start or a bi-directional PV start starts from D and a rising PV start starts from A. When PV is at (3) in the figure, any PV start starts from A.

NOTE

PV start is valid for segments in the selected program but not for segments beyond

a pattern link destination.

■ Cycle

The cycle function allows you to repeat operation from segment 1 to the last

segment in a program pattern the number of times set in the cycle count. A total of

10,000 times can be set.

When a cycle number of n is set, the total operation count is n + 1. During cycle

operation, the operation at the last point in the final segment is not performed and

executed values of program items (sequels to settings in the previous segment ; for

example, PV event value, pid group number) that continue from a previous

segment are cleared before program restart.

When the SP start point and end point are not equal, SP changes in a step-like

manner during cycle operation.

■ Pattern link

The pattern link function links patterns; the program number of the link at the

destination is set in the pattern link item. An initial value of 0 indicates that linking

is not performed.

When the number of the program is set in the pattern link item, it forms an eternal

loop.

When SP at the end of the original link and SP at the destination are not equal, SP

changes in step-like manner.

When cycle operation has been set, the pattern link operates after the cycle

operation has been completed.

Since operation starts from the first segment at the destination during pattern

linking, executed values of program items (sequels to settings in the previous

segment) that continue from a previous segment are cleared before program

restart.

When a PV start has been programmed in a pattern at the destination link, the PV

start function operates after the link has been made.

PID computations are not initialized but continued after a link has been

established.

When the READY mode is invoked at the end of an operation or in a RESET

operation, operation returns to program number 1 that is switched from READY to

RUN mode (RUN to READY). If a RESET is performed when a program at the

pattern link destination is reached during an ADV operation in the READY mode,

operation returns to segment 1 of the link destination program number. Note,

however, that program numbers selected using the external switch takes priority.

■ Mode types

Modes are listed below.

● Program operation

The program is run according to SP, time, events and other settings made in

program patterns 1-99.

● Constant value control

The control is run according to SP and events made with the constant value control

data.

● READY

READY indicates that the program is ready to run.

MV becomes fixed and events whose operation depends on values set in the segments are turned off. Note, however, that DCP551 state dependent events still

run.

Program numbers between 1 to 99 and set segment numbers can be selected during

program operation.

All setup data, some event configuration data and some constant value control data

parameters can be changed in the READY mode.

Memory cards can also be used in the READY mode.

● RUN

The RUN mode indicates that the program is run sequentially.

MV output and events operate during PID control, ON-OFF control and other

types of control. In the program RUN mode, program operation progresses

according as time elapses. Note, however, that G.SOAK (guarantee soak) wait,

like the HOLD mode, halts program operation.

● HOLD

The HOLD mode temporarily halts program operation.

Note, however, that, like the RUN mode, MV output and events operate during

PID operation, ON-OFF control and other types of control. During constant value

control the HOLD mode cannot be invoked.

● FAST

The FAST mode is essentially a speeded-up version of the RUN mode. The time factor is selected using variable parameter PA39. MV output and events operate

during PID control, ON-OFF control and other types of control. G.SOAK

(guarantee soak) settings are ignored.

During constant value control the FAST mode cannot be invoked.

● END

The END mode indicates the state of a program that has run its course.

When a program stops at the end, MV output and events operate during PID

control, ON-OFF control and other types of control.

During constant value control the END mode cannot be invoked.

● READY FAST

The READY FAST mode is a combination of the READY and FAST modes.

MV output, SP output and events operate in the same way as in the READY mode.

Program numbers and segment numbers cannot be selected. Parameters that can

only be changed in the READY mode and memory card operation is not possible

in this mode.

During constant value control the READY FAST mode cannot be invoked.

● AUTO

The AUTO mode performs automatic operation. MV outputs can be used depending on DCP551 control. (Note, however, that when programmer functions are selected, DCP551 dependent SP outputs operate.)

● MANUAL

The MANUAL mode performs manual operation.

The “ ”, “ ”, “ ” and “ ” console keys can be used to change

communications and MV output.

(Note, however, that when setter functions are selected, communications and SP

output can be changed.)

■ Mode transitions

● Program operation

Mode transitions are indicated by the solid line arrows and end operation is

indicated by the dashed lines in the figure below.

NOTE

• AUTO ⇔ MANUAL mode changes can be made in the boxes of each mode.

• READY and END at the end of operation can be selected using setup data

C31.

● Constant value control

Mode transitions are indicated by the solid line arrows.

NOTE

AUTO ⇔ MANUAL mode changes can be made in the boxes of each mode.

● Switching between program operation and constant value control

Constant value control data “ConSt ” control mode item in the READY mode is

used to switch between these two modes.

0: Program operation 1: Constant value control

NOTE

Constant value control is available only when setup data setting C21 is set to more than 0. When C21 is set to 0, ConSt is also set to 0.

■ Mode transition operations

Mode transitions are performed using the following operations.

Although “Operation end” is not an operation, it is described here as a factor in

mode transitions.

● RUN

Switches from the READY, HOLD, FAST and READY FAST modes to the RUN

mode. To go from the READY mode or READY FAST to the RUN mode using keys, external switches or transmission, the DCP551 must be in basic display

status.

● HOLD

Switches from the RUN and FAST modes to the HOLD mode. During constant

value control the HOLD mode cannot be invoked.

● RESET

Switches from the RUN, HOLD, FAST, END and READY FAST modes to the

READY mode.

In program operation, the reset involves returning the program to the first segment.

● ADV

Brings the program forward by one segment in the READY, RUN, HOLD, FAST

and READY FAST modes. ADV (advance) operation is not available in the

constant value control mode.

● FAST

The FAST mode is invoked from the RUN, HOLD, READY and READY FAST

modes. During constant value control the FAST mode cannot be invoked.

● AUTO

Switches from the MANUAL mode to AUTO mode.

● MANUAL

Switches from the AUTO mode to MANUAL mode. The basic display status

changes as follows during this transition.

•A controller function displays PV and output value (%).

• The programmer function displays PV and SP.

Switching from AUTO to MANUAL using external switches or transmission

invokes the basic display status even when the parameter setting status or

programmer setting status are in use.

● Operation end

Operation ends when all progress of program settings including cycle and pattern

links reach the end in the RUN, FAST and READY FAST program operation

modes or during an ADV operation. By making a setup selection, it is possible to

set READY or END as the state of the controller when the program reaches its

end.

Note, however, that when an operation ends in the READY FAST mode, it always

ends in the READY mode. In constant value control mode, operation end is not

available.

5 - 4 Controllers and Programmers

Setup data C21 allows the user to select the controller function or the programmer function.

● Controller

PID controller computations can be performed using PV, SP and PID set values

and the result of the manipulated variable is output via an analog output.

ON-OFF control can be used instead of PID control.

In the MANUAL mode, manipulated variable levels can be controlled by keys

available in the basic display status.

● Programmer

PID control computations are not performed and 4 to 20mA output of scaled SP

signals are output.

In the MANUAL mode, SP levels can be controlled by keys available in the basic

display status.

NOTE

The constant value control mode cannot be invoked when the programmer

function is used.

■ Channel switching (PV input 2 channel model)

● Switching types

The following switching types are provided.

• Selecting high and low-temperature sensors for PV CH1 (CH1 below) and PV

CH2 (CH2 below)

(1) CH1 is a low-temperature sensor + CH2 is a high-temperature sensor

(2) CH1 is a high-temperature sensor + CH2 is a low-temperature sensor

• CH tied for control use

PV tied for operation and control

(1) Tied CH1 PV

(2) Tied CH2 PV

• Backup switching

Two temperature sensors are used. Thus if one sensor should breakdown, the

program can switch to the other and continue normal operation. The main

channel (CH1) is used for operation and control. In the event of an overrange

(up or downscale), the subchannel (CH2) is used for operation and control to

ensure normal operation. When both the main and subchannels are in

overrange, the main channel is used.

The manipulated variable setting during this overrange is valid. The normal

channel is CH1 and the subchannel is CH2. Note, however, that when 7 is set in one of setup data C71 to C74, this situation is reversed when an external

switch is turned on.

NOTE

Switching type Setup data setting C25

0: Low-temperature CH1, high-temperature CH2 1: Low-temperature CH2, high-temperature CH1 2: CH1 setting 3: CH2 setting 4: Backup switching

● Low-temperature, high-temperature switching systems

The following switching system is used when CH1 is a low-temperature sensor

and CH2 is a high-temperature sensor or CH1 is a high-temperature sensor and

CH2 is a low-temparature sensor.

• Switching using the external switches

To switch using the external switches, set 0 in setup data C26 and 7 in one of settings C71 to C74.

Switch to CH1 when the external switches are off and switch to CH2 when they

are on. When the external switches are off, the CPL communications command

(WS or WB) can be used to switch between CH1 and CH2.

• Automatic changeover A

Set 1 in setup data setting C26 to allow automatic changeover to set the

temperature (switch point) where channels are switched and the dead band

setting that prevents switch chattering. Examples 1 to 4 below describes switch

operations.

Example 1:

(1) When the high-temperature sensor senses that the temperature has risen to

changeover point A, the channel switches from the low-temperature to the

high-temperature sensor.

(2) No switching is performed at changeover point C when the high-

temperature sensor senses that the temperature has only reached point B

and does not exceed the upper limit of the dead band.

(3) When the high-temperature sensor senses that the temperature has dropped

to point D the lower limit of the dead band, the channel switches from the

high-temperature to the low-temperature sensor.

Example 2:

(1) When the temperature rises and the high-temperature sensor senses that the

temperature has risen to changeover point A, the channel switches from the

low-temperature sensor to the high-temperature sensor.

(2) When the high-temperature sensor senses that the temperature has risen

above the upper limit of the dead band and reached point B, the channel

switches from the high-temperature to the low-temperature sensor at

changeover point C.

high-temperature sensor.

(2) When the high-temperature sensor senses that the temperature has risen

above the upper limit of the dead band and reached point B, the channel

switches from the high-temperature to the low-temperature sensor at

changeover point C.

(3) No switching is performed at changeover point E when the high-

temperature sensor senses that the temperature has only dropped to point D

and has not gone below the upper limit of the dead band.

(4) When the high-temperature sensor senses that the temperature has reached

point F at the upper limit of the dead band, the channel switches from the

high-temperature to the low-temperature sensor at changeover point C.

Example 4:

(1) When the high-temperature sensor senses that the temperature has risen to

changeover point A, the channel switches from the low-temperature to the

high-temperature sensor.

(2) When the high-temperature sensor senses that the temperature has risen

above the upper limit of the dead band and reached point B, the channel

switches from the high-temperature to the low-temperature sensor at

changeover point C.

(3) When the high-temperature sensor senses that the temperature has dropped

to point D the lower limit of the dead band, the channel switches from the

high-temperature to the low-temperature sensor at changeover point E.

• Automatic changeover B

To combine external switch input conditions with automatic changeover A, enter 2 in setup data setting C26 and 9 or 10 in one of settings C71 to C74. When 9 is entered in C71 to C74 and the external switch is on, it is tied to

channel 1. When it is off, it is possible to switch channels from channel 1 to 2. When 10 is entered in C71 to C74 and the external switch is on, it is tied to

channel 2. When it is off, it is possible to switch channels from channel 2 to 1.

• Automatic changeover C

Enter 2 in setup data C26 when the PV to be calculated is the value between the

low-temperature sensor and high-temperature sensor in the dead band range.

The switch operation is described in the following example.

(1) When the high-temperature sensor senses that the temperature has dropped

below point A, the lower dead band limit, the channel switches from the

high-temperature sensor to the low-temperature sensor.

(2) When the high-temperature sensor senses that the temperature has risen to

between point A, the lower dead band limit, and point B, the higher dead

band limit, the controller calculates the value between the low-temperature

sensor and the high-temperature sensor. The ratio of the high-temperature

sensor varies between 0% at point A and 100% at point B.

(3) When the high-temperature sensor senses that the temperature has risen

above point B, the higher dead band limit, the channel switches from the

low-temperature sensor to the high-temperature sensor.

(4) When the high-temperature sensor senses that the temperature has dropped

below point C and is going towards point D, the controller calculates the

value between the low-temperature sensor and the high-temperature sensor.

NOTE

• When switching between automatic changeover A to C, make sure that the

changeover point is set in the overlapping area between the high-

temperature and low-temperature sensors and 1/2 inside the deadband.

• When there is a temperature difference between the two inputs from high-

temperature and low-temperature sensors, PV reflects this but the control

output performs a PID computation to prevent a major disturbance from

occurring. When a major disturbance occurs in the control output, select

automatic changeover C.

• Select setup data setting C29 when an initial changeover setting is desired

at power on during automatic changeover A and B. When set to 0, the

power stays off; when set to 1, a switch is made to CH1; and when set to 2

a switch is made to CH2.
