If...Then ... Else Statement Example
The example illustrates the various forms of the If...Then...Else syntax.
Dim X, Y, Temp( 5 ) 'Declare variables.
X = Temp( 1 )
If X < 10 Then
Y = 1 '1 digit.
ElseIf X < 100 Then
Y = 2 '2 digits.
Else
Y = 3 '3 digits.

Power Off
Used to turn the CR5000 off until a designated time.
Syntax
PowerOff(StartTime, Interval, Units)
Parameter
& Data Type Enter
Start Time
Array The name of a six element array that contains the start time: Year, month,
day, hour, minutes, and seconds, respectively.
Interval
Constant Enter the time interval on which the CR5000 is to be powered up.
Units The units for the time parameters.
Constant Alpha
Code Numeric
Code
Units
SEC 2 seconds
MIN 3 minutes
HR 4 hours
DAY 5 days
Remarks
This instruction sets a time to power up and then shuts off CR5000 power.
Only the clock continues running while the CR5000 is powered down. When
the time to power up arrives, the power is restored, the CR5000 reloads its
program from Flash memory and begins running.
The interval allows the CR5000 to periodically power up and execute a program.
StartTime is a time value. If StartTime is in the future when PowerOff is
executed, it is the time the CR5000 will be programmed to power up. If
StartTime is in the past when PowerOff is executed, The CR5000 will set the
time to power up to the next occurrence of the interval (using StartTime as the
start of the first interval)
The units for the interval are days, hours, minutes, or seconds.
When the CR5000 is in this power off state the ON Off switch is in the on position
just like when the CR5000 is turned off from the keyboard’s configure menu. The
CR5000 will wake up if a key is pressed on the keyboard or in response to
communication on the CSI/O or RS232 ports.
