CAPTURE
Captures are used to obtain a snapshot of the VRC unit. Captures
include data from the metering, status, and command channels
and includes the date and time of the capture.
To create a capture of the VRC unit, begin a new line in the
macro with the word “CAPTURE” followed by the site and unit ID
numbers, then end the line with a carriage return or colon.
Each VRC2500 can store up to 192 captures. An alarm will be
generated any time that the buffer is 75% full. The VRC Scheduler
can be configured to automatically download these captures.
Macros within macros do
not act as sub-routines.
They will run concurrently
with the originating macro. If you
need to execute a full macro
sequence prior to running another
macro, see the sub-procedure
example on page 119.

Macro Line Example Description
Capture ME, ME [CR] A capture will occur for this I/O unit at this site immediately
DELAY
For various reasons, it may occasionally be necessary to include
a pause between lines of code. The DELAY command will
accomplish this task. Delay time is set in seconds and tenths of
seconds.You will need to use a decimal point to indicate tenths of
seconds. The maximum value available for a delay time is 6,553.5
seconds or 1 hour 49 minutes and 13.5 seconds.
REMARK
Remarks can be placed anywhere within a macro. Remarks must
be enclosed by single quote (‘ ‘) marks. A remark is not a
functioning part of the macro. It is for user understanding only.
Macro Line Example Description
‘Limits changed for lower power’ [CR] Any text in single quote marks is a remark.
Macro Line Example Description
Delay 60.4 [CR] Wait 60.4 seconds before executing the next line of code
Delay 3600 [CR] Wait 6 minutes before executing the next line of code
