Explanation

For details on the settings, consult your system or network administrator.

• Host Name

Set the recorder’s host name and the domain name of the network to which the
recorder belongs. Be sure to set these items when using the DNS.

• Host

Set the recorder’s host name using up to 64 alphanumeric characters.

• Domain

Set the network domain name to which the recorder belongs using up to 64
alphanumeric characters.

• IP Address, Subnet Mask, and Default Gateway

• IP address

• Set the IP address to assign to the recorder. The default value is 0.0.0.0.

• The IP address is used to distinguish between the various devices connected to
the Internet when communicating using the TCP/IP protocol. The address is a
32-bit value normally expressed with four values (0 to 255), each separated by a
period as in 192.168.111.24.

• M (Subnet Mask)

• Specify the mask that is used to determine the network address from the IP
address. The default value is 0.0.0.0.

• Set this value according to the system or the network to which the recorder
belongs. In some cases, this setting may not be necessary.

* When the key, key, or key is pressed while holding down the SHIFT key,
the operation is reversed as when the respective key is pressed by itself.

CHARACTER

2.3 Configuring the Ethernet Interface

• G (Default Gateway)

• Set the IP address of the gateway (router, etc.) used to communicate with other
networks. The default value is 0.0.0.0.

• Set this value according to the system or the network to which the recorder
belongs. In some cases, this setting may not be necessary.

• Setting the DNS (Domain Name System)

The DNS is a system that correlates the host name/domain name to the IP address.
The host name/domain name can be used instead of the IP address when accessing
the network. The DNS server manages the database that contains the host name/
domain name and IP address correlation.

• On/Off

Select On when using the DNS.

• P (Primary DNS Server)

Set the IP address of the primary DNS server. The default value is 0.0.0.0.

• S (Secondary DNS Server)

Set the IP address of the secondary DNS server. The default value is 0.0.0.0. If
the primary DNS server is down, the secondary server is used to search the host
name and IP address correlation.

• Suffix_P (Primary Domain Suffix), Suffix_S (Secondary Domain Suffix)

When the recorder searches another server using the DNS server, the domain
name of the recorder is appended to the host name as a possible domain name if it
is omitted. If the IP address corresponding to the server name is not found on the
DNS server, then it may be that the system is configured to use another domain
name for searching. This alternate domain name is specified as the domain suffix.

• Set the domain suffix using up to 64 alphanumeric characters.

• Up to two domain suffixes can be specified (primary and secondary).

Note

• The method used to eliminate noise varies depending on the situation. In the connection

example, the shield of the cable is connected only to the recorder’s ground (one-sided

grounding). This is effective when there is a difference in the electric potential between the

computer’s ground and the recorder’s ground. This may be the case for long distance

communications. If there is no difference in the electric potential between the computer’s

ground and the recorder’s ground, the method of connecting the shield also to the computer’s

ground may be effective (two-sided grounding). In addition, in some cases, using two-sided

grounding with a capacitor connected in series on one side is effective. Consider these

possibilities to eliminate noise.

• When using the two-wire type interface (Modbus protocol), the 485 driver must be set to high

impedance within 3.5 characters after the last data byte is sent by the host computer.

• Serial Interface Converter

On some non-recommended converters, the signal polarity may be reversed (A/B or
+/- indication). In this case, reverse the connection.

CAUTION

Some converters have FG and SG pins that are not isolated. In this case, do
not connect anything to the converter’s FG and SG pins (unlike the figure on the
previous page). Especially in the case of long distance communications, the
potential difference that appears may damage the recorder or cause
communication errors. For converters that do not have the SG pin, they can be
used without using the signal ground. For details, see the manual that came
with the converter.

3-5

3.2

Terminal Arrangement and Signal Names and the Connection Procedure of the RS-422A/485 Communication Interface

For a two-wire system, the host computer must control the transmission driver of the
converter in order to prevent collisions of transmit and received data. When using the
recommended converter, the driver is controlled using the RS (RTS) signal on the RS-

232.

• When Instruments That Support Only the RS-422A Interface Exist in the System

When using the four-wire system, up to 32 recorders can be connected to a single
host computer. However, this may not be true if instruments that support only the RS­422A interface exist in the system.

When the instrument that support only the RS-422A interface exist in the
system

The maximum number of connection is 16. Some of OMEGA’s conventional recorder
only support the RS-422A driver. In this case, only up to 16 units can be connected.

Note

In the RS-422A standard, 10 is the maximum number of connections that are allowed on one

port (for a four-wire system).

• Terminator

When using a multidrop connection (including a point-to-point connection), connect a
terminator only to the recorder on the end of the chain. In addition, turn the terminator
on the host computer ON (see the computer’s manual). If a converter is being used,
turn ON its terminator. The terminator must be attached externally to the
recommended converters.

3.3 The Bit Structure of One Character and the
Operation of the Receive Buffer

The Bit Structure of One Character

The serial interface on the recorder communicates using start-stop synchronization. In
start-stop synchronization, a start bit is added every time a character is transmitted. The
start bit is followed by the data bits, parity bit, and stop bit. (See the figure below.)

Chapter 4 Commands

4.1 Command Syntax

The syntax of the setting/basic setting/output commands (see sections 4.4 to 4.7) of the
instrument is given below. ASCII codes (see appendix 1) are used for the character codes.
For the Maintenance/Test command syntax, see section 4.9.
For the Instrument Information server command syntax, see section 4.10.

Command name Parameter

Command example

SR 02,SKIP;SR 03,VOLT,2V,-1500,1800

• Command Name

Commands

Parameter (02 SKIP·····1800)

Delimiter (,)

Command name (SR)

Sub delimiter (;)

• Parameter

• Command parameters.

• Set using alphabet characters or numerical values.

• Parameters are separated by delimiters (commas).

• When the parameter is a numerical value, the valid range varies depending on the
command.

• Spaces before and after of the parameter are ignored (except for parameters that
are specified using an ASCII character string (unit, tag, and message string), when
spaces are valid.)

• You can omit the parameters that do not need to be changed from their current
settings. However, delimiters cannot be omitted.

Example SR 01,,2V<terminator>

If multiple parameters are omitted and delimiters occur at the end of the command,
those delimiters can be omitted.

Example SR 01,VOLT,,,<terminator> → SR 01,VOLT<terminator>

• The number of digits of the parameters below is fixed. If the number of digits is not
correct when entering the command, a syntax error results.

• Date YY/MM/DD (8 characters)

YY: Year (Enter the lower two digits of the year.)
MM: Month
DD: Day

• Time HH:MM:SS (8 characters)

HH: Hour
MM: Minute
SS: Second

• Channel number: 2 characters (Example: 01, 0A)

• Relay number: 3 characters (Example: I01)

• Communication input data: 3 characters (Example: C02)

• Constants used in the computation function (/M1 option): 3 characters

(Example: K03)

• Remote control (/R1 option) input terminal status: 3 characters (Example: D04)

4-1

4.1 Command Syntax

• Query

• A question mark is used to specify a query.

• By placing a query after a command or parameter, the setting information of the
corresponding command can be queried. Some commands cannot execute
queries. For the query syntax of each command, see sections 4.4 to 4.7.

Example 1 SR[ p1]? SR? or SR p1? can be executed.
Example 2 SA[ p1[,p2]]? SA?, SA p1?, or SA p1,p2? can be executed.

• Delimiter

• A comma is used as a delimiter.

• Parameters are separated by delimiters.

• Sub Delimiter

• A semicolon is used as a sub delimiter.

• By separating each command with a sub delimiter, up to 10 commands can be
specified one after another. However, the following commands and queries cannot
be specified one after another. Use them independently.

• Output commands other than BO, CS, and IF commands.

• YE command

• Queries

* If there are consecutive sub delimiters, they are considered to be single. In addition, sub

delimiters at the front and at the end are ignored.

Example ;SR01,VOLT;;;SR02,VOLT;<terminator> is taken to be

SR01,VOLT;SR02,VOLT<terminator>.

Response

• Terminator (Terminating Character)

Use either of the following two characters for the terminator.

• CR + LF (0DH 0AH in ASCII code.)

• LF (0AH in ASCII code.)

Note

• The total data length from the first character to the terminator must be less than 2047 bytes. In

addition, the character string length of 1 command must be less than 512 bytes.

• Commands are not case sensitive (with the exception of user-specified character strings).

• All the commands that are listed using sub delimiters are executed even if one of the

commands is erroneous.

• Spaces that are inserted before and after a parameter are ignored. However, if spaces are

inserted before a command, after a sub delimiter, or after a query, an error occurs.

The recorder returns a response (affirmative/negative response) to a command that is
separated by a single terminator.* The controller should follow the one command to one
response format. When the command-response rule is not followed, the operation is not
guaranteed.
For the response syntax, see section 5.1.

* The exceptions are the RS-422A/485 dedicated commands (see section 4.8).

Note

When using the RS-422A/485 interface, allow at least 1 ms before sending the next command

after receiving a response. Otherwise, the command may not be processed correctly.

4.2 A List of Commands

Execution Modes and User Levels

Execution Modes

The recorder has two execution modes. Each command is specified to be used in a
particular execution mode. If you attempt to execute a command in a mode that is
different from the specification, a syntax error occurs. Use the DS command to switch to
the appropriate mode, and then execute the command. Query commands can be
executed in either mode.

• Basic Setting mode
Measurement/computation is stopped and settings are changed in this mode.

• Run mode

Responses

• The table above shows the different types of BINARY Data.

• Measured/computed data can be output using the FD command.

• FIFO data can be output using the FF command.

• The setup data file can be output using the FE command. The setup data file can

be loaded in the cofiguration software.

• The identifier section in the “Conceptual diagram” on the previous page contains

the ID number shown above.

Note

BINARY data that are not indicated in the above table are considered undefined files.

• Calculating the Sum Value

If you set the parameter of the CS command to “1 (enabled),” the checksum value is
output only during serial communications. The check sum is the same as that used in
the TCP/IP and is derived according to the following algorithm.

Buffer on Which the Sum Value Is Calculated

• For the header sum, it is calculated from “data length + flag + identifier” (fixed to 6

bytes).

• For the data sum, it is calculated from “BINARY data.”

5.1 Response Syntax

If the data length of the buffer is odd, a “0” is padded so that it is even. (1) through (6)
are summed as unsigned two-byte integers (unsigned short). If the digit overflows a
“1” is added. Finally, the result is bit-wise inverted.

Sample Program

The sum value is determined using the following sample program, and the calculated
result is returned. The sum determined by the sample program can be compared with
the header sum of the output BINARY header section and the data sum of the output
BINARY footer section.

5.3 Output Format of BINARY Data

This section describes the output format of the BINARY data that is disclosed. For the
BINARY output format, see “BINARY Output” on page 5-2. For other BINARY data
types, see “Identifier” on page 5-3.
The measured data is output using signed 16-bit integer; the computed data is output
using signed 32-bit integer. These integers can be understood as physical values by
adding the decimal point and the unit.

Typical Examples to Obtain Physical Values

BINARY Value Decimal Position Code Physical Value (Measured Value)

10000 0 10000
10000 1 1000.0
10000 2 100.00
10000 3 10.000
10000 4 1.0000

Measured/Computed Data and FIFO Data

• The FD (FD1) command is used to output the most recent measured/computed data.

• The FF (FEGET, FERESEND, and FEGETNEW) command is used to output the
FIFO data. The decimal point position and unit can be determined using the FE
command.

• The ID number of the output format is 1. See “Identifier” on page 5-3.

• The IF command can be used to set the filter.

• The IS command is used to output the status information. Status information 1 and 2
are cleared when they are output. Status information 3 and 4 are not cleared when it
is output, and remains at “1” while the event is occurring.

• When multiple connections are up, filters can be specified for the individual

Appendix 2 Output Flow of FIFO Data

The recorder has a dedicated internal memory for outputting measured/computed data.
This memory is structured as a FIFO (First-In-First-Out). Measured/computed data are
constantly acquired to the internal memory at the specified acquiring interval (FIFO
acquiring interval, set with the FR command). By using this function, it is possible to
read measured/computed data that have been saved at the specified intervals
regardless of the frequency at which the PC periodically reads the measured/computed
data.

The following example shows the case when the acquiring interval is 1 s and the
buffer capacity is for 8 intervals.

Block 1

2

Block 8

4

Most recent acquire
Position: WP

Previous read
Position: RP1

Current read
Position: RP2

• Acquiring of the measured/computed data

• The measured/computed data are acquired to the internal memory at 1 s intervals.

• Measured/computed data are acquired to blocks 1 through 8 in order. After

acquiring to block 8, the next acquiring operation returns to block 1.

• Reading the measured/computed data (FF GET command is used, logging
output)

Outputs the data from the next to the previous read position (RP1) to the most recent
acquire position (WP).
In this example, more than 2 s has elapsed from the previous read operation.
Therefore, data in blocks 5 and 6 are output.

• Reading the measured/computed data (FF GETNEW command is used, output
of the most recent value)

Output the specified number of blocks of FIFO data back starting from the recent
acquire position (WP).
In this example, if you specify the number of blocks to “5,” data in blocks 2 to 6 are
output.

The buffer capacity varies depending on the model.

Pen model: 240 intervals (30 s at an acquiring interval of 125 ms)
Dot model: 60 intervals (60 s at an acquiring interval of 1 s)
