3.5 Description of codes

 The codes from ① STX, ② address to ⑩ ERR type as indicated below are expressed in

ASCII codes.

 For the ASCII codes, see "11. Table of ASCII codes."

 For conversion to ASCII codes, see "4. Examples of TOHO communications."

① STX

This code is needed for the receiver to detect the top of the message. It is affixed to the top

of a character string to be sent.

② Address

This is the address of the party (this product) with whom a high-level computer

communicates. The address in the response message from this product indicates the sender

of the response message.

③ Contents requested

Enter a code R / W. / L / B

R: to read data from this product

W: to write or store data in this product

L: to read blind setting from this product

B: to write or store blind setting in this produc

④ Identifier

An identifier is a classification code (identifier) for data to be read or written and expressed

in a three-digit alphanumerical ASCII code. See "10. Table of identifiers (codes)."

⑤ Numerical data

In writing mode, you can write 5 or 6 digits of numerical data. In reading, you can set this

product to 5 or 6 digits of numerical data. Following are the conditions for switchover

between 5 and 6 digits.

Negative data: The "-" (minus) sign is in a single digit at the largest digit.

Position of the decimal point: 5-digit data does not include a decimal point.

Example: The table below indicates the significances of 5-digit numerical data -9999

Example

Significance of the

decimal point setting (DP) is 0

-9999

decimal point setting (DP) is 0.0

-999.9

decimal point setting (DP) is 0.00

-99.99

decimal point setting (DP) is 0.000

-9.999

Decimal point setting (DP) is

0.0000

-0.9999

When the character data is “ INP”.

Example: The table below indicates the significances of 6-digit numerical data -10000
