Communication timeout

This function drops the connection if no data transfer is detected between the PC and
the RD-MV over a predetermined period of time. This applies to data transfer at the
application level only (see section 1.1). For example, this prevents a PC from being
connected to the RD-MV indefinitely which would prohibit other users from making
new connections.

1.2 Explanation of the Functions

Note

• Depending on the reliability of the network or the volume of network traffic, all the transferred

data may not be retrieved by the PC.

• Communication performance deteriorates if multiple PCs access the recorder simultaneously.

2.3 Configuring the Ethernet Interface

Explanation

The following configurations must be made in order to use the Ethernet communication
functions of the RD-MV.

Setting the IP address, subnet mask, default gateway, and DNS

Confirm the settings such as the IP address, subnet mask, default gateway, and DNS
with the administrator of the system or network on which the recorder is to be used.

• IP address

• Set the IP address to assign to the RD-MV. The default setting 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.

• Subnet mask

• Specify the mask that is used to determine the network address from the IP

address. The default setting is “0.0.0.0.”

• Set this value according to the system or the network to which the RD-MV

belongs. In some cases, this setting may not be necessary.

• Default gateway

• Set the IP address of the gateway (router, switch, etc.) used to communicate

with other networks. The default setting is “0.0.0.0.”

• Set this value according to the system or the network to which the RD-MV

belongs. In some cases, this setting may not be necessary.

• 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.

• DNS server

• Set the address of the DNS server. The default setting is “0.0.0.0.”

• Up to two DNS servers can be specified (primary and secondary). If the
primary DNS server is down, the secondary server is used to search the host
name/domain name and IP address.

• Host name
Set the RD-MV’s host name using up to 64 alphanumeric characters.

• Domain name

• Set the network domain name to which the RD-MV belongs using up to 64

alphanumeric characters.

• When searching the data transfer destination using the DNS server, this

domain name is attached after the destination name (server). The

2.5 Setting the FTP Client (Automatic Transfer of
Display/Event/Report Data Files)

Explanation

By setting this function, the display/event and report data files that are created in the
internal memory can be automatically transferred using FTP when the files are created.
Note that the Ethernet interface must be configured beforehand (see section 2.3).

Selecting the files to transfer

• You can select whether or not to automatically transfer the display/event data file
and the report data file. The default setting is “Off.”

• When the method to save the data is set to “Auto,” the data files are automatically
transferred at appropriate times to the FTP destination described in the next
section.

• Display data file: Automatically transferred at auto save intervals.

• Event data file: Automatically transferred when the specified length of data is
written.

• Report data file: Automatically transferred when reports are created.

Note

• For details related to saving data to the external storage medium and the auto save interval,

see the RD-MV100/RD-MV200 User’s Manual (M-3641/M-3642).

• When the method to save the data is set to “Manual,” auto transfer does not take place. You

can still output the display/event/report data files using commands.

• For the format of the report data file, see the RD-MV100/RD-MV200 User’s Manual (M-3641/

M-3642). However, the report data file to be transferred is divided by every timeout.

• If a file with the same name exists at the destination, it is overwritten without any warning

messages.

Setting the FTP connection

Confirm the settings such as the primary and secondary FTP servers, port number,
login name, password, account, PASV mode, and initial path with your system or
network administrator.

• Setting the primary and secondary servers

Specify the primary and secondary file transfer destinations (FTP servers) as
described in the previous close. When the primary FTP server is down, the data
are automatically transferred to the secondary FTP server.

• FTP server name

Set the FTP server name using up to 64 alphanumeric characters.

• When the DNS is being used, the host name can be used to specify the server
name.

• For DNS settings, see section 2.3.

• You can also specify the IP address. In this case, DNS is not necessary.

• Port number

Set the port number of the destination FTP server in the range from 0 to 65535.
The default setting is 21.

• Login name

Set the login name to use when accessing the FTP server. Up to 32 alphanumeric
characters can be used.

2-10

2.5 Setting the FTP Client (Automatic Transfer of Display/Event/Report Data Files)

• Password

Set the password to use when accessing the FTP server. Up to 32 alphanumeric
characters can be used.

• Account

Set the account (the ID number) to use when accessing the FTP server. Up to 32
alphanumeric characters can be used.

• PASV mode

When using the RD-MV behind a firewall that requires the PASV mode, turn this
mode “On.” A firewall is a security feature on a router which is used to prevent
undesired intrusion into the network from outside parties.

• Initial path

Set the destination directory for the file transfer using up to 64 alphanumeric
characters. The directory delimiter varies depending on the FTP server.
Example: When transferring files to the directory “data” which is a sub directory of

the “home” directory on a UNIX file system, use the forward slash “/” as
the directory delimiter:

/home/data

Note

If the file transfer to both the primary and the secondary servers fails, the RD-MV aborts the

file transfer. When the connection to the destination is recovered, the RD-MV transfers the

data files that were not transferred along with the new data file. However, due to the

limitation of the internal memory, files that are overacquired before they are transferred are

lost. For details related to the acquiring operation to the internal memory, see the RD-

MV100/RD-MV200 User’s Manual (M-3641/M-3642).

When using the RS-232 interface for transferring data, it is necessary for equipment on
both sides to agree on a set of rules to ensure the proper transfer of data. The set of
rules is called handshaking. Because there are many handshaking methods that can be
used between the instrument and the PC, one must make sure that the same method is
chosen by both the RD-MV and the PC. You can choose any of the four methods
shown in the following table.

Using the Serial Interface (Option)

OFF-OFF

• Data transmission control
There is no handshaking between the RD-MV and the PC. The X-OFF and X-ON
signals are treated as data, and the CS signal is ignored.

• Data reception control
There is no handshaking between the RD-MV and the PC. When the received
buffer becomes full, all overflow data are discarded.
The RS signal is fixed to True.

3-3

3.2 RS-232 Interface Connector Pin Arrangement and Signal Names, the Connection Procedure, and Handshaking

XON-XON

• Data transmission control
Software handshaking is performed between the RD-MV and the PC. When an X­OFF code is received while sending data to the PC, the RD-MV stops the data
transmission. When it receives the next X-ON code, it resumes the data
transmission. The CS signal received from the PC is ignored.

• Data reception control
Software handshaking is performed between the RD-MV and the PC. When the
amount of used space in the received buffer reaches 1537 bytes, the X-OFF code
is transmitted. When the amount of used space in the received buffer falls to 511
bytes, X-ON code is transmitted. The RS signal is fixed to True.

XON-RS

• Data transmission control
Software handshaking is performed between the RD-MV and the PC. When an X­OFF code is received while sending data to the PC, the RD-MV stops the data
transmission. When it receives the next X-ON code, it resumes the data
transmission. CS signal from the PC is ignored.

• Data reception control
Hardware handshaking is performed between the RD-MV and the PC. When the
amount of used space in the received buffer reaches 1537 bytes, the RS signal is
set to “False.” When the amount of used space in the received buffer falls to 511
bytes, the RS signal is set to “True.”

CS-RS

• Data transmission control
Hardware handshaking is performed between the RD-MV and the PC. When the
CS signal becomes False while sending data to the PC, the RD-MV stops the data
transmission. When the CS signal becomes True, it resumes the data
transmission. X-OFF is treated as data.

• Data reception control
Hardware handshaking is performed between the RD-MV and the PC. When the
amount of used space in the received buffer reaches 1537 bytes, the RS signal is
set to “False.” When the amount of used space in the received buffer falls to 511
bytes, the RS signal is set to “True.”

Note

• The PC program must be designed so that the received buffers of both the RD-MV and the

PC do not become full.

• When using XON-XON, output the data in ASCII format.

Note

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

example, only the cable shield on the RD-MV side is connected to ground (one-sided

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

PC’s ground and the RD-MV’s ground. This may be the case for long distance

communications. If there is no difference in the electric potential between the PC and the

RD-MV, two-sided grounding, in which the PC side is also grounded, may be effective.

Furthermore, using two-sided grounding and connecting a serial capacitance on one-side

may be 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

Recommended converter: MODEL RC-57 by RA SYSTEMS CORP., or Z-101HE by
Sharp

CAUTION

Some converters not recommended by Omega FG and SG pins that are not
isolated. In this case, do not connect anything to the FG and SG pins as
shown in the diagram on the previous page. This can generate a potential
difference, especially for long distance communications, and can damage the
instrument or cause communication abnormalities. 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.

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

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

When using the four-wire type interface, up to 32 RD-MVs can be connected to a
single host computer. However, this may not be true if the instrument that support
only the RS-422-A interface exist in the system.

When Omega's recorders that support only the RS-422-A interface exist in the
system

The maximum number of connection is 16. Some of Omega’s conventional
recorders (HR2400 and µR, for example) only support the RS-422-A driver. In this
case, only up to 16 units can be connected.

Note

In the RS-422-A 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
terminal resistance to the RD-MV on the end of the chain. Do not connect a terminal
resistance to a RD-MV in the middle 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. An external terminator must be attached to the
recommended converter. However, there are converters that have built-in
terminations.

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

The Bit Structure of One Character

The serial interface on the RD-MV communicates using start-stop synchronization.
With the 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.)

(dotted line)
or the start bit of the next data
(solid line)

Stop bit (1 or 2 bits)

Receive Buffer and Received Data

The data received from the computer are first placed in the receive buffer of the RD-MV.
Depending on the available free space in the receive buffer, the received data are
processed as shown in the figure below. When the receive buffer becomes FULL,
overflow data are discarded.

2047 bytes

Amount of used space is 1537 bytes Free

Amount of used space is 511 bytes

Amount of used space is FULL

Free

1 character

Data bits

(7 or 8 bits)

Parity bit
(Even, odd, or none)

When handshaking is used, the
MV stops data reception when
data in the buffer cannot be
processed fast enough and the
amount of used space reaches
1537 bytes.

After the data reception is
stopped as described above,
data in the buffer continues to
be passed to the internal
program. When the amount of
used space falls to 511 bytes, it
resumes data reception.

If the buffer becomes full in
spite of the handshaking
control, all overflow data are
discarded.

Chapter 5 Commands

5.1 Command Syntax

Command Syntax

The syntax of the setting/basic setting/output commands (see sections 5.4 to 5.9) of the
instrument is given below. ASCII codes are used for the character codes. For the
syntax of the maintenance/test commands (see section 5.10) and instrument information
output commands (see section 5.11), see the corresponding sections or the examples
for each command.

Command name

Parameter

Delimiter

Sub delimiter

?

Terminator

Command example

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

Parameter (02 SKIP ... 1800)

Delimiter (,)

Command name (SR)

Sub delimiter (;)

Command name

Defined using two alphabet characters.

Parameter

• Command parameters.

• Set using alphabet characters or numerical values.

• Parameters are separated by delimiters.

• All numerical values are specified using integers.

• 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), 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

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

• Date YY/MM/DD (8 characters)

• Time HH:MM:SS (8 characters)

• Channel number: 2 characters

• Relay number: 3 characters

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

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

HH: Hour
MM: Minute
SS: Second

5

Commands

5-1

5.1 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 5.4 to 5.7.
Example 1
Example 2

SR[ p1]? SR? or SR p1? can be executed.
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.

• YO 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

• Do not specify a channel or relay number that is not available on the RD-MV. An error will

occur.

• The total data length from the first character to the terminator must be less than 2047 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 RD-MV returns a response (affirmative/negative response) to a command that is
delimited 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 6.1.

* Commands dedicated to RS-422-A/485 (see section 5.9) and instrument information output

commands (section 5.11) are exceptions.

5.2 A List of Commands

Basic Setting Commands

• In order to activate the settings that are changed using the basic setting
commands, the settings must be saved using the XE command. Make sure to
save the settings with the XE command before changing from the basic setting
mode to the operation mode. Otherwise, new settings will not be activated.

• The settings that are returned in response to a query in the basic setting mode will
contain the new settings even if they are not saved with the XE command.
However, the new settings will not be activated until they are saved. In order to
activate the new settings, the XE command must be issued as described earlier. If
the settings are not saved or cleared using the XE command and the execution
mode is changed from the basic setting mode to the operation mode, the settings
that are returned in response to a query will contain the settings that existed before
they were changed.

Note

• The settings that are changed using the YA/YK/YN/YQ/YS command are activated after

saving the new settings using the XE command and rebooting the RD-MV.

• When executing the YO command, the communication is disconnected.

SJ 31,1

Description • This command can be used on models with

the computation function option /M1.

• This command cannot be specified while

computation is in progress.

• About p3

In the sum computation, sampled data are

summed over the scan interval. However,

when a physical value is measured over a

period of time, the actual value may not match

the computed result. (This is due to the fact

that the scan interval and the time unit are

different.) In these cases, set p3 to the same

unit as the time unit of the physical value.

The summed value is calculated according to

the following converting equation depending

on the parameter.

OFF Σ(measured value)

/S Σ(measured value) × scan interval

/MIN Σ(measured value) × scan interval/

60

/HOUR Σ(measured value) × scan interval/

3600

The scan interval unit is in seconds.

SS Sets the date and time at which

FR Sets the acquiring interval to the

FIFO buffer

Syntax FR p1<terminator>

p1 FIFO acquiring interval (125MS,

250MS, 500MS, 1S, 2S)

Query FR?

Example Set the FIFO acquiring interval to 1 s.

FR 1S

Description • 125MS, 250MS, and 500MS apply only to

models RD-MV102, RD-MV104, RD-MV204,

and RD-MV208.

• Set the acquiring interval to a value greater
than the scan interval.

• If the scan interval is set to a value less than
the acquiring interval using the XV command
or from the screen, the acquiring interval is
automatically set equal to the scan interval.

• The RD-MV has a circular FIFO buffer. The
measured/computed values are acquired to
the internal memory at predetermined time
intervals from the time the power is turned
ON, and the data are output when a FF
command is received. The previous output
position is held for each connection and is
updated when the next set of data is output
with the FF command. Using this
functionality, data can be collected without
data dropouts if the PC reads the data in the
circular buffer before the data are
overacquired. This compensates for the
communication time differences that result
from periodically retrieving data from the RD­MV at a rate determined by the processing
power of the measurement PC. For the
output flow of FIFO data, see appendix 4.

Chapter 6 Response

6.1 Response Syntax

The following table shows the types of responses for the various commands described in
the previous chapter.
The RD-MV returns a response (affirmative/negative response) to a command that is
separated by a single delimiter. The controller should follow the one command to one
response format. When the command-response rule is not followed, the operation is not
guaranteed.

Function

Setting/
Measurement

* For the responses to the instrument information server function, see section 6.4.

Note

The “CRLF” used in this section denotes carriage return line feed.

Affirmative Response

When the command is processed correctly, an affirmative response is returned.

Syntax

E0CRLF

Example

E0

Single Negative Response

When the command is not processed correctly, a single negative response is returned.

Syntax

E1_nnn_mmm···mCRLF

nnn Error number (001 to 999)

mmm···m Message (Variable length, one line)

_ Space

Example

E1 001 "Syntax error"

Multiple Negative Responses

• If there is an error in any one of the multiple commands that are separated by sub
delimiters, multiple negative response are returned.

• The response is generated for each erroneous command.

• If there are multiple commands that have errors, the negative responses are
separated by commas.

• The error position number is assigned to the series of commands in order starting with
“1” assigned to the first command.

Syntax

• When the BO flag is “0,” the MSB is output first. When the BO flag is “1,” the LSB is
output first.

• If the check sum is enabled (parameter = 1) using the CS command parameter, each
sum value is inserted in the header sum and data sum sections in the “Conceptual
diagram” on the previous page. If the check sum is disabled (parameter = 0), a zero
is inserted in the header sum and data sum sections. For a sample program that
calculates the sum value, see “Calculating the sum value” on the next page.

• When the amount of data output in response to a ME, MI, or MO command is large,
all of the data may not be able to be returned in one output request (parameter GET).
In this case the END flag becomes “0.” You must send output requests (parameter
NEXT) to receive the rest of the data until the END flag becomes “1.”

• The bits that have “–” for the name and flag are not used. The value is undefined.

6.1 Response Syntax

/*
* Sum Calculation Function (for a 32-bit CPU)
*
* Parameter buff : Pointer to the top of the data on which the sum is calculated
* len : Length of the data on which the sum is calculated
* Returned value : Calculated sum
*/

Calculating the sum value

When the CS command parameter is set to “1,” check sum values are 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.”

1 byte

(1) (2) (3) (4) (6)

(5)

Padding

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). When 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.

p = (unsigned short *)buff;

for(i=0;i<len;i++) /* Sum using an unsigned short data type. */

csum += *p++;

if(odd){ /* When the data length is odd */

union tmp{ /* Pad with a 0, and add to the unsigned short data. */
unsigned short s;
unsigned char c[2];
}tmp;
tmp.c[1] = 0;
tmp.c[0] = *((unsigned char *)p);
csum += tmp.s;

}

if((csum = (csum & 0xffff) + ((csum>>16) & 0xffff)) > 0xffff)

csum = csum - 0xffff; /* If the digit overflows again, add a 1. */

return((~csum) & 0xffff); /* bit inversion */

}

/* Pointer to the next two-byte data word in the buffer that is to be summed. */
