1.4 Data Configuration

The relation between the signal and the potential of the RS-422-A terminals is as
follows: A<B :1

1.4.1 Start-Stop Communication

The RS-422-A interface communicates with the start-stop system. The start-stop system
first adds the start bit to the head and then in turn adds the data bits (7 to 8 bits), parity
bit and stop bit(s) in every transmission of one character (see figure 1.4). See section 1.5
for the address, communication (baud) rate, data length, parity bit, and stop bit(s)
settings.
The start bit is automatically added and no setting is necessary.

Communication data usually takes the form of more than one character to which a
terminator is added. This is called ‘text’. See also figure 1.5.

Figure 1.6 Example of Two Texts, Where the Terminator is CR-LF

NOTE This recorder identifies text by regarding ‘LF’ or ‘;’ as the terminator when receiving

the data (and will send CR and LF as the terminator).
However, only CR + LF is usable as the terminator for open command (ESC O) and
close command (ESC C).
As in the example shown in figure 1.6, when CR and LF are used as the terminator, CR
is ignored. Therefore, when communication is performed with a PC, the terminator LF
might not be sent. Exercise care.

1.4.3 Input Buffer

1.4.4 Buffer Overflow

1.4 Data Configuration

The input buffer takes the form of rotary buffer (capacity: 256bytes). The rotary buffer
outputs a text on the first-in first-out basis while storing data in turn. It is not necessary
for the user to be aware of in the program, however take care to prevent buffer over­flow. A merit of the rotary buffer is that it can flexibly cope with more than one text
being sent contiguously because of low loss against variable text length.

As described before, the input buffer is necessary for data communication. The capac­ity, however, is limited (256 bytes for this recorder). Thus, in the receiver,
the buffer capacity may become shorted if vast data is sent in a short time.
These impair data communications (buffer overflow).
To prevent buffer overflow, it is recommended to confirm the status of the recorder
using the ESC S command just after commands have been sent (from the PC). See
subsection 2.4.2.
Note that you cannot send an ESC S command after having sent an LF or FM command.
After the recorder receives the ESC S command, it will output its status to the PC.
Actually, the recorder will store the ESC S command in the input buffer and this
command will be read from this buffer. Then the status will be output to the PC.
If the computer sends other commands before the status of the recorder has been
receiveid, the input buffer will not be empty (the ESC S command will be still in there),
which means the recorder cannot receive other commands yet.

2 RECEIVING FUNCTIONS

This chapter describes program set commands and program control commands. Re­member first to open a device by the ESC O command before the set or control com­mands can be sent.

2.1 Program Set Commands

2.1 Program Set Commands

Commands are represented by ASCII codes and divided into an identifier, parameters,
delimiters and a terminator.
Example: SA02, 1, ON, L, 1000, ON, I04 terminator

parameter
identifier

identifier

• Defined by two alphabetical, capital characters

parameter

• Parameters are separated by a delimiter (comma)

• Numeric data are displayed by integers (e.g. +20, –240)

• When parameters are numeric, the effective setting ranges depend
on these parameters

• Spaces preceding and following a parameter, or a space within a
parameter are ignored.

• Parameters which do not need to be changed can be omitted.
Delimiters, however, can not be omitted. (e.g. SA02, , ON: level
number of alarm is unchanged)

• A string of delimiters at the end of a command/parameter string may be
omitted (see example below).
E.g. SA02, 1, ON, L, , , can be omitted

• The length of the following parameters is fixed. If the length differs,

syntax errors will occur.

- Date and time YY/MM/DD (eight characters)

HH:MM:SS (eight characters)

- Channel CC (two characters, e.g. channel 1 must be entered

as 01)

terminator

A command ends with one of the following terminators:

CR + LF
LF
; (semicolon)

When using the ESC O or ESC C command, only the CR + LF terminator
is valid.

2.3 Escape Sequence

Communications can be controlled by using the following escape commands.

2.3.1 Execution of Trigger

ESC T executes triggering

If an ESC T command is received,

• measured data (when TS0 is specified), or

• units & decimal point information (when TS2 is specified)

are stored in a buffer.
Data output will start only after the output format has been designated (using the FM or
LF command).
For actual use and output sequence, see section 3.2, ‘‘output data format’’.
ESC T sends a character ‘T’ following data of 1 byte (1B) H.

2.3.2 Status Output

ESC S outputs status

Example: If (ESC T) is output using PC 9801 Series:

PRINT #1,CHR$ (&1HB) +’T’;
(In case of NEC PC 9801, the interface file number should be
1 and should be opened.)

If the ESC S command is received, statuses of the commands which have been sent so
far are output.
Output statuses range from ER00 to ER07. For the respective contents, see the next
figure and table.

If an error message is output, all error statuses will be reset. This error will not be reset.
If there are no statuses to be output when the ESC S command is received, ER00 will be
output.
Data from the recorder is output using an FM or LF command. To allow time to output
these data, do not send an ESC S command immediately after sending the FM or LF
command.
ESC S sends a character ‘S’ following data of 1 byte (1B) H.

Example: If (ESC S) is output using PC 9801 Series:

PRINT #1,CHR$ (&1HB) +’S’;
LINE INPUT #1, D$
PRINT D$
(In case of NEC PC 9801, the interface file number should be

2 RECEIVING FUNCTIONS

2.3.3 Open Command

2.3.4 Close Command

(ESC O)_ CRL

F

where is the address (ASCII code ‘01’ to ‘16’)

The open command is to address a communication destination when a HOST (PC) is
connected to more than one (up to 16) recorders.
This command always controls non-addressed devices.
Before issuing an open command, make sure that the previous address device is closed
by a close command.
All commands (incl. ESC T) are valid for the addressed (after ESC O) device only.

Only CR + LR can be used as the terminator.

(ESC C)_ CRL

F

where is the address (ASCII code ‘01’ to ‘16’)

The close command is to close the addressed state of a device. Only the addressed
device will respond to this command.

Only CR + LR can be used as the terminator.

3.1 Introduction to Output Data Formats

3 TRANSMITTING FUNCTIONS

This chapter describes different output formats.

3.1 Introduction to Output Data Formats

The format to output data can be specified by the following commands (see subsection

2.2.9):

• TS0

• TS1, TS2

NOTE When you specify a TS command and send an ESC T command, the TS command will

be reset. However, if you send an ESC T command again, the TS command will be set
to the previous value.

3.1.1 TS0

After sending the TS0 and the ESC T command, you must specify the output format
using an FM command. Data cannot be output when an FM command is omitted.
However, after the FM command has been sent, data within the same sample can be
output again by specifying the output format once more using an FM command. If the
next FM command is sent before the specified data have been output completely, the
newly requested data will be output.

3 TRANSMITTING FUNCTIONS

3.1.2 TS1, TS2

Sequence (see also subsection 2.2.9, 2.2.10)

TS0
ESC T
FMx, xx, xx
(read data completely)
FMx, xx, xx
(read data completely)

NOTE Do not send any FM or LF commands until the data have been sent completely.

After sending an ESC T command, data will be stored in a buffer and the system will
wait for FM or LF commands. (Regardless whether the ESC T command is sent without
executing FM or LF command, or whether data have been sent completely.)
The ASCII code for ESC is (1B)H.

After sending the TS1 (or TS2) and the ESC T command, you must specify the output
channel using an LF command. It is possible, after data have been output completely, to
output data from another channel by specifying an LF command again.

Sequence (see also subsection 2.2.9, 2.2.10)

TS2
ESC T
LFxx, xx
(read data (end data))
LFxx, xx
(read data (end data))

NOTE Do not send any FM or LF commands until the data have been sent completely.

After sending an ESC T command, data will be stored in a buffer and the system will
wait for FM or LF commands.

3 - 1

3.2 Output Data Formats

There are four formats which can be used to output data.

• TS0 + ESC T + FM0 (outputs measured values in ASCII mode)

• TS0 + ESC T + FM1 (outputs measured values in Binary mode)

• TS1 + ESC T + LF (outputs values of setting parameters)

• TS2 + ESC T + LF (outputs information on unit and decimal point)

3.2.1 Output Format of Measured Values in the ASCII Mode

When the TS0, ESC T and FM0 commands are received, the measured value and
computed result are output in ASCII mode. When the ESC T command is received
immediately after the TS0 command, the recorder data will be transferred to a buffer.

6.1 Preventing Errors

6 ERRORS DURING RS-422-A OUTPUT

6.1 Preventing Errors

Do not send an FM or LF command until the measured data or set point data in the
specified channel is output. If an FM or LF command is sent during data output, the
communication will be interrupted.

If an LF command (to set TS0) or an FM command (to set TS1 or TS2) is sent, the
communication will be interrupted.

If an ESC T command was already sent when TS0 is set, data (even in other formats) in
any channel can be output with an FM command. Data received with the last ESC T is
output.

If an ESC T command was already sent when TS1 or TS2 is set, data set in any channel
can be output with an LF command. If an ESC T command was already sent, the
measured data and set point data can be output on a channel-by-channel.
If an ESC T command has already been sent, the measured value and set value can be
output over more than one time.

NOTE When data is sent from the PC to the recorder, use the ESC S command to avoid buffer

overflow:
This recorder receives an ESC S request, and saves it in the buffer memory. This
request is retrieved from the buffer memory and, after command acknowledgement, the
status is sent to the PC. Make sure not to send any other commands between sending the
ESC S command to the recorder and reading the status from the recorder. Commands
can be only received by the recorder when its input buffer is empty.

6 ERRORS DURING RS-422-A OUTPUT

Example (Dot-printing model):

10 OPEN "COM1:N81N" AS #1
20 '
30 PRINT #1,CHR$(&H1B)+"O 01"
40 PRINT #1,"SA02,1,ON,L,1000,ON,I04"
5 0 GOSUB *HANDSHAKE
60 PRINT #1,"PS0"
7 0 GOSUB *HANDSHAKE
80 PRINT #1,"UD0"
90 PRINT #1,CHR$(&H1B)+"C 01"
1 0 0 CLOSE
110 END
120 *HANDSHAKE
130 PRINT #1,CHR$(&H1B)+"S"; (sending ESC S)
140 LINE INPUT #1,STS$ (reading status)
1 5 0 RETURN

to prevent buffer overflow

Command length of input buffer of this recorder is 256 bytes.

NOTE When the PC9801 receives binary data from the recorder, set the memory switches so

that the PC9801 can use a DEL mode as a BS(08) code. For memory setting, see the
PC9801 Instruction Manual.

6 - 1

NOTE Binary data cannot use a LINE INPUT statement. To read binary data, use an INPUT$

statement.

Example (Dot-printing model):

10 OPEN "COM1:N81N" AS #1
20 '
30 PRINT #1,CHR$(&H1B)+"O 01"
40 PRINT #1,"BO1"
50 PRINT #1,"TS0"
60 PRINT #1,CHR$(&H1B)+"T";
70 PRINT #1,"FM1,01,04"
80 D$=INPUT$(2,#1) (to designate data length of read data)
90 CNT=CVI(D$)
100 D$=INPUT$(CNT,#1)
1 1 0 CLOSE
120 END

Execution of the above program may result in the following:
After line 100 has been executed, binary data will be stored in D$.
It the output data length "CNT" in line 90 exceeds 255, the read-data is separated into
several parts.
When binary data is handled in an integer array on a 2-byte basis, the least significant
byte is followed by the most significant byte, so an FM command should specify an
output byts from the LSB (least significant byte) (line 40).

6.2 How to Request for Error Message Output

If an error occurs when a supervisory computer sends a setting or control command to
the recorder via the RS-422-A communication interface, an error message can be output
from the recorder upon receipt of a command from the computer.

1 request to output error message number

command: ESC S

(1B) H (53) H

2 error message output from the recorder when ESC S is received.

Output format: ERxx (CR) (LF) (xx = 00 to 07. Refer to 3.3 for details)

NOTE An error message is only output when an ESC S command is sent.

If an ESC S command (request to send error message) is sent to the recorder while data
is being output due to the receipt of a TS0 or TS2 command, communication will be
interrupted.
When data is transmitted between a supervisory computer and the recorder, it is possible
to monitor the errors during communication through the ESC S command.

6.3 Timing of Resetting Error Status

When the recorder receives an ESC S command following the occurrence of an error,
the recorder outputs the corresponding error message and the error status is simultane­ously reset.

error occurs ESC S command is sent

6 - 2
