Command Format

5.1 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

• Channel number

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

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

For details of channel numbers, see page 5-4.

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 5-4.
