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.
