21X MICROLOGGER OVERVIEW
OV-14
Instruction Parameter Description
(Loc.:Entry) (Par.#:Entry)
04:P77 Output Time
01:10 Store hour and minute.
05:P71 Average
01:1 One repetition.
02:2 Source of TC temps to be
averaged, Input Storage location 2.
To obtain daily output, the If Time instruction is
again used to set the Output Flag and is
followed by the Output Instructions to store time
and the daily maximum and minimum
temperatures and the time each occurs.
Any Program Control Instruction which is used
to set the Output Flag high will set it low if the
conditions are not met for setting it high.
Instruction 92 above sets the Output Flag high
every hour. The Output Instructions which
follow do not output every hour because they
are preceded by another Instruction 92 which
sets the Output Flag high at midnight (and sets
it low at any other time). This is a unique
feature of Flag 0. The Output Flag is set low at
the start of each table (Section 3.7).
