IMPORTANT NOTE ABOUT FLAGS:
FLAG 01 is a special ag that triggers result calculation for AVER-
AGE, MINIMUM, MAXIMUM and STANDARD DEVIATION instruc-
tions when they use the BLOCK method. The ag has no effect
when the MOVING method is used.
FLAG SET is used to set a ag ON or OFF. Use ags to signify
the occurrence of some event and trigger a response (see IF
FLAG).
ag#= Flag number (01 to 16)
state= Flag state (ON or OFF)
FLAG SET MASK sets the state of all ags using a hexadecimal
mask.
mask= Hexadecimal mask value (0000-FFFF)
state= Flag state (ON or OFF)
FLAG TIME INTERVAL sets the state of FLAG# when current
time aligns with an interval. When UNIT is set to MIN (minute),
TIME interval is limited to 1440 (equivalent to 24 hours). The
PROGRAM INTERVAL parameter must be set to 00 or 01 for
this instruction to operate correctly.
unit= Time unit (SEC or MIN)
time= Time alignment (0001-9999)
ag#= Flag number (01-16)
state= Flag state (ON or OFF)
IMPORTANT NOTE ABOUT IF INSTRUCTIONS:
All IF instructions must have a matching END IF instruction. Only
one optional ELSE instruction may be inserted between them.
Example:
 IFFLAG
  instruction(s)...
 ELSE(optional)
  instruction(s)...(optional)
 ENDIF
IF FLAG tests whether FLAG# is ON or OFF.
ag#= Flag number (01-16)
state= Flag state (OFF or ON)
IF FLAG MASK tests all ags against a hexadecimal ag
mask. LOGIC parameter determines whether ANY or ALL ags
matching the mask will satisfy the condition. STATE parameter
determines whether we are looking for ON ags or OFF ags as
dened by the mask.
mask= Hexadecimal mask (0000 to FFFF)
logic= Match logic (ANY or ALL)
state= Comparison state (OFF or ON)
IF KEYSWITCH tests whether any of the 3 user soft-keys are
pressed during OPERATE MODE.
key= Key value (KEY1, KEY2, or KEY3)
IF LOC1 COMPARE LOC2 compares the values in SLOC1
and SLOC2.
sloc1= Source location 1 (001-256)
comp: < less than
<= less than or equal to
>= greater than or equal to
> greater than
<> not equal to
= equal to
sloc2= Source location 2 (001-256)
IF LOC1 COMPARE VALUE compares the value in SLOC to a
xed value.
sloc1= Source location 1 (001-256)
comp: < less than
<= less than or equal to
>= greater than or equal to
> greater than
<> not equal to
= equal to
val= Value to compare
IF LOC SPAN tests the value in SLOC against two setpoint val-
ues. SPAN determines how to compare the value in SLOC to the
range dened by SETPOINT 1 and 2. INCL (inclusive) compares
SLOC to values inside the range. EXCL (exclusive) compares
SLOC to values outside the range. DELAY sets the duration the
compare condition must be met to consider the comparison true.
sloc= Source location (001-256)
set1= Setpoint 1
set2= Setpoint 2
delay= Time delay seconds (00-99)
span= Span logic (INCL or EXCL)
IF TIME INTERVAL tests current time to against a time interval.
When UNIT is set to MIN (minutes), TIME interval is limited
to 1440 (equivalent to 24 hours). The PROGRAM INTERVAL
parameter must be set to 00 or 01 for this instruction to operate
correctly.
unit= Time unit (MIN or SEC)
time= Time interval (0001-9999)
INPUT FREQ measures pulses per second on FREQ INPUT
channels. LOW-AC congures the detector for a low-level AC
signal. TTL/SW congures the detector for a TTL logic-level or
switch-closure signal. Apply a multiplier and offset with MULT
and OFFS if needed. Result stored in DLOC.
Switch-closures require a pull-up resistor. See appendix B for
wiring examples.
chan= Frequency Input channel (1-4)
type= Input type (LOW-AC or TTL/SW)
mult= Multiplier value
offs= Offset value
dloc= Destination location (001-256)
INPUT PRECIP (TIPPING BUCKET) measures precipitation
from a tipping bucket sensor using FREQ INPUT channels.
RESO parameter sets the resolution per tip. Apply a multiplier
with MULT if needed. Current 1-hour precipitation is stored at
DLOC. Additional results are stored in six locations following
DLOC. DO NOT allow other instructions to store values in these
locations.
chan= Frequency input channel (1-4)
reso= Tip resolution
mult= Multiplier value
dloc= Destination location (001-256)
Current 1-hour precipitation
dloc+1 Last 1-hour precipitation
dloc+2 Current 24-hour precipitation
dloc+3 Last 24-hour precipitation
dloc+4 1-hour rate based on 5-minute sample
dloc+5 Rate total (used internally)
dloc+6 Raw pulse count (used internally)
