ANSI X3.28 "=" Command Example
The "=" Command sets a specific 733/734 prompt to a specific value. The general
command syntax applies to all commands. The definition and number of argu-
ments depends on the command itself. See Table 5, Pages 17.
In this example, you want to change the Alarm 1 Low value to 500°. Here, the "="
command will do the job.
'"=" command Syntax with ANSI X3.28 Protocol:
With the "=" command, data.1 is the Series 733/734 prompt, in this case Alarm 1
Low , A1LO. Data.2 is the value you want to set for that prompt, in this example,
500.
