1.1 Description of Functions

Status Byte Format

The format of status byte output in serial polling is as follows:

Upper-level byte

0

Bit 8: Not used. Always 0.
Bit 7: SRQ

Bit 6 This bit changes to 1 when a measurement release is generated while the computation is in

Bit 5 This bit changes to 1 when the chart reaches its end.
Bit 4 This bit changes to 1 after storing data on media, or reading data from media; otherwise, it

Bit 2: This bit changes to 1 when a syntax error occurs in a command and is normally 0.

Bit 1: This bit changes to 1 at the end of an A/D conversion; otherwise, it is 0.

Lower-level byte

Interrupt generated at the end of A/D conversion.
Interrupt generated at the time of syntax error.
Interrupt generated when the internal timer is being operated

or hourly, daily and monthly reports are created.

Interrupt generated after storing data on media, or reading
data from media (with a floppy disk drive).

Interrupt generated at the time of chart end.

Interrupt generated when measurement release is generated
while computation is in progress (with computation
functions).

SRQ

This bit changes to 1 when any cause of the bits 1 to 3 or bit 5 has been generated and

interrupts the controller. After responding to serial polling, this bit is set to 0.

progress; otherwise, it is 0. This bit is effective only with optional computation functions.
After responding to serial polling, this bit is set to 0.

is 0. After responding to serial polling, this bit is set to 0.

If there is an error in a command description, this changes to 1. After responding to serial

polling, this bit is set to 0.

When the A/D conversion of measured data is terminated, this changes to 1. After responding

to serial polling, this bit is set to 0.

Status byte and serial polling

• In IM commands, the bit status that is to be made effective must be specified. The status of
unspecified bits does not change to 1.

• If a new cause is generated before reading out a status byte for which a cause has already been
generated, the existing cause remains in the status byte as is and the new cause is added. For
example, if bit 1 is in 1 state and bit 2 is newly changed to 1 before reading out the status byte,
both bit 1 and bit 2 become 1.

The initial value

The initial value is ‘ IM2 ’.

2.4 Handshake Format Selection

In order to ensure proper data transfers between the recorder and the host computer via the RS-232­C interface, a mutual procedure is required for processing the electrical signals. Such a procedure is
referred to as a ‘handshake’. Several handshake formats are available, with selection depending on
the host computer being used. The same handshake format must be designated for both the recorder
and the host computer.
The recorder parameter settings permit any one of the following 5 formats to be selected.

Reception Data Control

(control format when receiving data

from the host computer)

Hardware

Handshake

When reception
of data becomes
impossible RTS
becomes
FALSE, when
data recept
becomes
possible RTS
becomes TRUE.

possible DTR
becomes TRUE.

OFF-OFF

• Transmission data control : There is no handshake status between the recorder and host
computer. the X-OFF signal from the host computer is processed
as data, and the CTS signal is ignored.

• Reception data control : There is no handshake status between the recorder and host
computer. When the recorder reception buffer becomes full, the
excess data is discarded.
DTR=True, RTS=True (both fixed).

No

Note

• It is necessary to create a host computer program which prevents the recorder and host computer reception buffers from
becoming full.

XON-RTS

• Transmission data control : A software handshake status is established between the recorder

• Reception data control : A hardware handshake status is established between the recorder

and the host computer. The recorder will stop a data transmission
when an X-OFF signal is received from the host computer. The
transmission will be resumed when the next X-ON signal is
received.
The CTS signal from the host computer is ignored.

and the host computer. When the recorder recept of data becomes
impossible, an ‘RTS=False’ status will be established. When data
recept becomes possible, an ‘RTS=True’ status will be established.
DTR=True (Fixed).

2.4 Handshake Format Selection

XON-DTR

• Transmission data control : A software handshake status is established between the recorder
and the host computer. The recorder will stop a data transmission
when an X-OFF signal is received from the host computer. The
data transmission will be resumed when the next X-ON signal is
received. The CTS signal from the host computer is ignored.

• Reception data control : A hardware handshake status is established between the recorder
and the host computer. When the recorder recept of data becomes
impossible, an ‘DTR=False’ status will be established. When data
recept become possible, an ‘DTR=True’ status will be established.
RTS=True (Fixed).

CTS-RTS

• Transmission data control : A hardware handshake status is established between the recorder
and the host computer. The recorder will stop a data transmission
if a ‘CTS=False’ status is established, and will resume the
transmission when a ‘CTS=True’ status is established. The X­OFF and X-ON signals from the host computer are processed as
data.

• Reception data control : A hardware handshake status is established between the recorder
and the host computer. An ‘RTS=False’ status will be established
when the recorder recept of data becomes impossible, and an
‘RTS=Ture’ status will be established when data recept becomes
possible. DTR=Ture (Fixed).

Overview and Specifications of RS-232-C Interface

CTS-DTR

• Transmission data control : A hardware handshake status is established between the recorder
and the host computer. The recorder will stop a data transmission
if a ‘CTS=False’ status is established, and will resume the
transmission when a ‘CTS=True’ status is established. The X­OFF and X-ON signals from the host computer are processed as
data.

• Reception data control : A hardware handshake status is established between the recorder
and the host computer. A ‘DTR=False’ status will be established
when the recorder recept of data becomes impossible and a
‘DTR=True’ status will be established when data recept becomes
possible. RTS=Ture (Fixed).

2.5 Communication Data Format

The RS-232-C interface uses a START-STOP communication format. With this format, a START
bit is placed at the beginning of each character transmitted, followed by the data bits, parity bit, and
stop bit, in that order. (See the figure below.)

3.1 Description of Functions

Listener and Talker Functions

Listener Function

This allows almost all settings except power on/off and operation control.

• Settings except communication settings.

• Operation control except power on/off.

• Call-up of setting data

• Specifying of output data (specifying of channel numbers or output data types)

Talker Function

The following data can be output:

• Measured data

• System configuration

• Data for operation mode setting

• Data for setup mode setting

For measured data, binary output or ASCII output can be selected. (for RS-422-A with using the
multi point.) Other data are output in the form of ASCII data.

Data Output

When trigger(GET) becomes activated DR will store the new data in a buffer. When an output
request such as the FM command is received, these new data will be output.

Commands Applicable to RS-422-A/RS-485 Only

The following commands are only applicable to RS-422-A/RS-485.

3

Overview and Specifications of RS-422-A/RS-485 Interface

ESC O Open Command (address a communication destination)

Setting ESC O xx<terminator>

xx : address, 01 to 31

Description Specifies the communicating device by its address. When this command is ex-

ecuted, all commands to the DR series (including ESC T) become effective.

• Only one device can be opened.

• Executing ESC O automatically closes all opened devices.

• When the DR series receives this command correctly, it sends “ESC O xx” in
response to the computer.

• CR+LF can only used for the terminator.

ESC C Close Command (close the addressed state of a device)

Setting ESC C xx<terminator>

xx : address, 01 to 31

Description Disconnects the device currently connected. When this command is executed, it

allows opening communication with other devices with the ESC O command.

• When the DR series receives this command correctly, it sends “ESC C xx” in
response to the computer.

• CR+LF can only used for the terminator.

The following commands are same as the RS-232-C interface. Refer to User’s Manual shown
below.

ESC T (Trigger Execution), ESC S (Status Output Command)

Note

• ESC corresponds to hexadecimal code (1B)H. On the N88-BASIC, “ESC x” is denoted as “CHR$(&H1B)+”x”.”

3.3 RS-422-A/RS-485 Interface Connection

Connecting to the Host Computer

Can be connected to a host computer with RS-232-C, RS-422-A, RS-485 ports.

• In the case of RS-232-C, a converter is used as shown in the diagram below.

• For information on recommended converters, refer to “Converters” in the latter.

• Dip switch needs to be changed depending on whether it is a two-wire system or four-wire sys­tem. Refer to “3.5 RS-422-A/RS-485 Interface Parameter Setting Procedure.”

In the case of four-wire system

In general, the recorder is wired to the host computer using a four-wire system. When four-wire
system is used, the send and receive wires need to be crossed.

Note

• The method in eliminating noise depends on the condition in which it is used. In the example, shielded cable is grounded

#1

#2 #n

(#n≤31)

No terminators are inserted between #1 through #n-1 (internal OFF)

only at the DR (one-sided grounding). This method is effective in eliminating noise in long distance communication in
which there is potential difference between the ground of the PC and the ground of the DR. When there is no potential
difference between the ground of the PC and the ground of the DR, grounding both sides (two-sided grounding) is sometimes
effective. In addition, there are cases when grounding both sides with one side having a capacitor connected in series is
effective.
Consider all the above cases in eliminating the noise.

3-5

3.3 RS-422-A/RS-485 Interface Connection

Converter

Recommended converter : Sharp Z-101HE

Some converters other than the recommended, do not have the FG and SG terminals
insulated. In such cases, do not connect as in the diagram on the previous page (do
not connect anything to the FG and SG terminals of the converter). Especially
when it is long distance, the potential difference may damage the devices or the
communication may become unreliable.
Also, converters without the SG terminal can be used without grounding. For
details, refer to the converter’s manual.

Some converters other than the recommended have their signal polarity reversed (indication of A/B
or +/-). In this case, reverse the connection. If the “RD” LED on the front panel of the RS-422-A/
RS-485 module blinks when it receives data, the connection is correct. If it lights, the connection
may be reversed.

In the case of the two-wire system, the host computer must control the ON/OFF of the transmission
driver of the converter in order to prevent the collision of the send and receive data. When using the
recommended converter, ON/OFF is controlled using RTS.

Caution

Using the Module with Devices Using the RS-422-A

Maximum of 31 devices with respect to 1 host computer can be connected with this module, but in
a system in which devices using the RS-422-A are used together, this may not be possible.

• In a system in which former recorders are used together
Some of the former recorders (such as HR2400 and µR) use the RS-422-A driver. In this case,
the maximum number of devices that can be connected is 16.

Note

• According to the RS-422-A standard, the maximum number of devices that can be connected with respect to one port is 10
devices (in the case of a four-wire system).

Terminator

When devices are connected in multi-drop configuration (includes point-to-point connections), turn
the terminators of the modules on the extreme ends ON. All modules in between should have them
turned off. Terminators are turned ON/OFF using the TERMIN switch on the front panel.
Also, turn ON the terminator on the host computer (refer to the computer’s manual). When convert­ers are used, turn their terminators ON also. The recommended converter needs an external termi­nator to be installed, but some converters are internal types.

3-6

Minimum Response Time

Because send and receive are done on the same line in the two-wire system, minimum response time
needs to be set. The minimum response time is the amount of time the RS-422-A/RS-485 module
waits in order for the host computer to be able to receive the data after it sends data. The time can be
set in the range from 0 to 100 ms. Set the time using the dip switch on the front panel of the RS-422­A/RS-485 module to match the computer or the converter’s specification. (Refer to “3.5 RS-422-A/
RS-485 Interface Parameter Setting Procedure.”) Note that the minimum response time is, as the
name indicates, the minimum time for responding. Not all responses will take place in this time.
In the four-wire system, the minimum response time does not need to be set (set to 0 ms).

4.1 Command Format

Commands are configured with ASCII codes and the content is divided into a command, parameters,
delimiters and a terminator.
(Example) SR001, VOLT, 20 mV <terminator>

Command

This is defined with two upper-case letters.

Parameter

• A delimiter (comma) is used to separate two parameters.

• Numerical values are all set using integers.

• If a parameter is a numeric value, the effective setting range varies with the command.

• Spaces before and after a parameter and embedded spaces in a parameter are ignored. (However,
for parameters (unit) specified with ASCII character strings, these spaces are effective.)

• Parameters which do not need to be changed from the current setting can be omitted. However,
delimiters cannot be omitted.
(Example) SR001,, 2 V <terminator>
If delimiters continue at the end due to the omission of more than one parameter, they can be
omitted.
(Example) SR001, VOLT,,, <terminator> -> SR001, VOLT<terminator>

• The number of digits of the following parameters is fixed. If an erroneous number of digits is
input, a syntax error occurs.

• Date and time

Date YY/MM/DD (8 characters)

YY: Year (enter the last two digits)
MM: Month
DD: Day

Time HH:MM:SS (8 characters)

HH: Hour
MM: Minute
SS: Second

4

Command Format

• Channel number

A channel number..................... 3 characters

Range of channel numbers ....... 6 characters AAA-BB

For details of channel numbers, see page 4-4.

Note

• If the same setting is to be done for subsequent channels, it can be achieved by connecting channels with a “-” (minus sign).
However, channels that can be set subsequently are effective only in the same unit.
(Example) Setting channels from 1 to 60 in subunit 0 to VOLT, 2 V:
SR001-60, VOLT, 2V

• Do not specify the channels of a module which the DR130/DR230/DR240 has not recognized. Otherwise, an error occurs.
Modules that cannot be recognized by the DR130/DR230/DR240 are those which have been newly added or whose slots
have been changed. In order for the DR130/DR230/DR240 to recognize them, reconstruct the system using the RS command.

• For specifying subsequent channels, the channels must all be in a module that can be recognized by the DR130/DR230/
DR240.

• Relay number
Relay numbers are expressed with 3 characters.
For details on the relay numbers, see page 4-4.

4-1

4.1 Command Format

Terminator

Any one of the following forms a terminator.

• CR + LF

•LF

• EOI = True
(If EOI is to be used for a terminator, add EOI = True to the last parameter character.)

Sub-delimita

Several commands can be executed in a row when they are divided by a semicolon (;).

Example

XA2, 2, 0.5 ; XV4 ; XI2, AUTO CrLf

Note

• The total data length from the first character to the terminator should not exceed 200 bytes.

• A sub-delimita cannot be used for the commands FM, LF, CF, RC, RS, DS, XE or XZ. These commands can only be
carried out one by one.

• In case of RS-232-C one ACK-status (E0/E1) will be output for each command devided by ;.

Comments • If the measurement range setting is SKIP, p3 can

only be set to OFF.

• In the following cases, alarm settings in that channel
are all canceled.

Change in the type of input (VOLT, TC .....)

Change in the measurement range
Change in the indicating span or scaling value
when the scaling indication is set (including a
change in decimal point position)
In differential input or RRJC, a change in
reference channel number or type of input/
measurement range
When the computation channel is set to on or off,
or the computational expression or measuring
span is changed
When the wiring method and the input range of
the power monitor module are change

• If contiguous channels are set to p1, the decimal point
in alarm values when the measurement ranges for
set channels differ take the positions determined for
each measurement range (see Pages 4-7 to 4-9). If
the result exceeds the measurable ranges, an error
occurs. For example, if the channels of measurement
ranges 20 mV, 2 V, and type T thermocouple are set
to p1 and the alarm value is set to 10000, the
following applies:

• The alarm value for the channel of the 20 mV

measurement range: 10.000 mV

• The alarm value for the channel of the 2 V

measurement range: 1.0000 V

• The alarm value for the channel of the type T

thermocouple: 1000.0°C

• Since the measurement range of the type T

thermocouple is -200.0 to 400.0°C, an error
occurs. For decimal point positions, see Pages 4­7 to 4-9.

• If p3 is off, the parameters for p4 and p5 are invalid.

• The dH or dL setting for p3 is effective only when
the input range is a differential input.

• If p3 is set to RH or RL, set the interval with the XA
command.

• The setting ranges of p4 alarm values are given on

Pages 4-7 to 4-9.

• Set the alarm value for the computation channel
within the range of a given recording span.

• Enter the p4 alarm value with up to 6 characters,
excluding the decimal point.
For computation channels, set the alarm value in no
more than 8 digits, excluding the decimal point.

• Setting the output relay number of a module that is
not connected to p5 causes an error. For details on
how to specify the relay number, see Page 4-4.

• Hysteresis should be set using the XA command.For
optional computation channel, the hysteresis is fixed
to 0.

• For the computation channel the only alarms, that
can be set are the upper limit alarm(H) and lower
limit alarm(L).

• The optional computation channel number is A01
to A30.

to 10, the interval for the rate-of-change limit on
decrease to 10, and the alarm hysteresis to 0.5% and
the alarm display is no retention.

error occurs. For example, if the channels of
measurement ranges 20 mV, 2 V, and type T
thermocouple are set to p1 and the boundary value
is set to 10000, the following applies:

• The boundary value for the channel of the 20 mV

measurement range: 10.000 mV

• The boundary value for the channel of the 2 V

measurement range: 1.0000 V

• The boundary value for the channel of the type T

thermocouple: 1000.0°C
Since the measurement range of the type T
thermocouple is -200.0 to 400.0°C, an error occurs.
For decimal point positions, see Pages 4-7 and 4-

8.

• The optional computation channel number for a
stand-alone model is A01 to A30.

• Set p4 to a value within the recording span, or within
the left/right scale if linear scaling is applied. It is
not possible, however, to set the recording span nor
the left/right scale.

Comments • This command is effective only with the optional

computation functions.

• p2 is effective for the totalization of flow signals,
which are expressed in engineering units — /s, /
min, /h.
If p2 is set according to the input unit, the
measurement data are computed based on that unit
at the specified measurement intervals. For example,
set the measurement interval to 2s, the input value
to 100 m3/min, and p2 to /MIN. By doing this,
because 2s/60s is multiplied for each measurement
interval, then after 1 minute, approximate actual
input values are obtained.

transferred to the operation mode.

• Since execution of the XE command takes an
indefinite time, return an ACK after the processing
is completed. On the controller side, execute the
next processing after receiving an ACK after
transmitting the XE command. The format of the
ACK status is as follows:

Commands

5-21

6.1 Functions as Talker

There are the following seven types of data output:

• Measured data output (ASCII code): TS0 + “Device Trigger (GET)” + FM0

• Measured data output (binary code): TS0 + “Device Trigger (GET)” + FM1

• Computed data output (ASCII code): TS0 + “Device Trigger (GET)” + FM2

• Computed data output (binary code): TS0 + “Device Trigger (GET)” + FM3

• Setting of data output in the operation mode: TS1 + “Device Trigger (GET)” + LF

• Unit and decimal point position data output: TS2 + “Device Trigger (GET)” + LF

• System configuration data output: TS5 + “Device Trigger (GET)” + CF

• A/D calibration data output: TS8 + “Device Trigger (GET)” + LF

• Setting of data output in the setup mode: TS9 + “Device Trigger (GET)” + LF

• Outputting of a file directory on a RAM disk: TS3 + [GET] + [MF0]

• Outputting of measured/computed data (ASCII code) on a RAM disk: TS3 + [GET] + MF1

• Outputting of the measured/computed data (binary code) on a RAM disk: TS3 + [GET] + MF2

• Outputting of channel on/off on a RAM disk: TS3 + [GET] + MF3

Measured data output (TS0/TS3)

After executing “GET,” be sure to output data using the FM or MF command. Execution of “GET”
alone without executing the FM or MF command does not output the data. After reading all the data
specified by the FM command, subsequent specification of the FM command without executing
“GET” enables the data within a scan to be output.
Because the MF command requests the output of data stored on the internal RAM disk, so a differential
in time occurs between the time when the data are measured and the time when [GET] is executed.

6

Output Format

Measured data output (TS1, TS2, TS8 or TS9)

After transmitting the device trigger “GET ”be sure to output data using the LF command. Execution
of “GET” alone without executing the FM command does not output the data. After reading all the
data specified by the LF command, subsequent specification of another channel using the LF command
enables the data contents to be output. A/D calibration data output by the TS8 command can be
executed in the A/D calibration mode only.

System configuration output (TS5)

After transmitting the device trigger “GET ”be sure to output data using the CF command. Execution
of “GET” alone without executing the CF command does not output data.

Note

• When using an RS-232-C, RS-422-A or RS-485 interface, execute an ESCT command rather than a GET command.

• Do not transmit the FM, LF, CF or MF command before outputting data for specified channels.

• If an FM, LF, CF or MF command is received while data are being transmitted, transmission of the data is suspended
automatically.

• If the type of output data is changed using the TS command after the execution of “GET,” the changed contents are not
reflected without executing “GET” again. Execute “GET” again.

• After executing “GET,” the execution of “GET” again without outputting data using the FM, LF, CF or MF command or
without completing the data output sets new data to the buffer. Be careful because old data are lost.

Channel numbers are output in the order of input channels and computation channels. For example,
when LF005 and A10 are set, the data are output starting from input channel 005 to the last input
channel. Then, the data are output starting from computation channels A01 to A10.
Data are output in the order of setting parameters subsequent to the setting command. Each data
item is delimited with a comma (,).

Range of outputting

If output data are issued on a unit or slot basis, the number of units or slots to which the data are
output is determined by specified channels. For example, if channels 002 to 036 are specified by the
LF command, data from slot 0 to slot 3 are output.

Note

• Data which are output for burnout and reference junction compensation are those of the channel up to the maximum
number connected in the specified range.

• Data which are output for the A/S integration time and AND/OR of relays are those of connected channels.

• Data which are output for energizing/deenergizing relays are output on the basis of the unit to which the module is connected.

• The data of XH command and XY command are output only when DI/DO module or alarm output module is mounted to
DR230/DR240.

• “S” as data of XN command is meaningless.

of channel 001 is nonzero.

Reset** RESET(): RESET(001):TLOG.SUM(002) When the channel 001 = nonzero, reset the integrated

value of the measured data of channel 002

* Previously measured data or computed data. In the case of computed data, the value is set to 0 when the

computation is reset. At the start of the computation, if the computation was reset, the value is “0”. If it was
not reset, the value is the last value of the previous computation. The value that can be specified inside the()
is limited to the input channel number (001 to 030) or the computation channel number (A01 to A30). Each
computing equation can be used once.

** When specifying HOLD(A):B or RESET(A):B, A and B are channel numbers or computing equations.

These can be used once in the beginning of the computing equation.

Computing equations are set according to the following rules.

The number of computing equations

“30” computing equations can be set. Each computing equation is assigned a number. The numbers
are “A01” to “A30”. These numbers are called computation channel numbers.

Data to be computed

- Measured data
Specified with channel numbers (example: 030).

- Computed data
Specified with computation channel numbers.

- Constants
“30” constants for the DR130/DR230/DR240 can be set. Each constant is expressed by a number
from “K01” to “K30” .

Priority of operators

The priority of operators in a computing equation is as follows. The operators are placed in order
from the highest priority.

Range when computing

When the value exceeds ±10

App-2

during the computation, computation error (overflow) occurs.

App.1 Computing Equation

Units in computing equations

In computations, measured data are handled as numbers without units. For example, if the
measured data of channel 001 is “20 mV” and the measured data of channel 002 is “20 V”, the
computed result of “001+002” becomes “40”.

Limitations in computing equations

Multiple operators can be used in 1 computing equation. But, there are following limitations.

- Number of characters that can be used : 40 characters

- Total number of channel numbers and constants: 16 (Computation error occurs when 16
exceeded, and the computed result becomes +OVER or -OVER)

- Computation channel numbers: Computation channel numbers less than the current computation
channel number can be used as variables within the computing equation.
Example: A02=001+A01 ← Computation channel numbers greater than or equal to A03 can not
be used in this computation.

- Statistical operators (TLOG. or CLOG.) can only be used once in 1 computing equation.

Control of the computing operation

There is a method to control using the data collection software and the method to control using the
event/action function described on the next page.

- Control using the data collection software
This software allows for the start/stop of the computation, and the clearing of the computed result

(select between just clearing or immediately compute after clearing).
