Keywords
In addition to the arithmetic status keywords, the controller supports these keywords.
Keyword | Access | Description |
S:FS | read | The first scan bit is set if this is the first, normal scan of the routines in the current program. |
S:MINOR | read write | The minor fault bit is set if at least one minor fault has been generated. The controller sets this bit when a minor fault occurs due to program execution. The controller does not set this bit for minor faults that are not related to program execution, such as battery low. |
THIS | na | The THIS statement is only valid with the GSV and SSV instructions that refer to a TASK, PROGRAM, or ROUTINE. Use THIS to specify the current TASK, PROGRAM, or ROUTINE. |
Keywords are not case sensitive.
Because these flags can change so quickly, these keywords are not animated in the programming software to actual show status.
You cannot define a tag alias to a keyword.
