CR23X MICROLOGGER OVERVIEW
OV-14
Storage locations on which to find maxima, (2)
TIME, an option of storing the time of
occurrence with the maximum value, and (3)
LOC, the first Input Storage location operated
on by the Maximum Instruction. The codes for
the TIME parameter are listed in the "Instruction
Option Codes".
The repetitions parameter specifies how many
times an instruction's function is to be repeated.
For example, four 107 thermistor probes may be
measured with a single Instruction 11, Temp-107,
with four repetitions. Parameter 2 specifies the
input channel of the first thermistor (the probes
must be connected to sequential channels).
Parameter 4 specifies the Input Storage location
in which to store measurements from the first
thermistor. If location 5 were used and the first
probe was on channel 1, the temperature of the
thermistor on channel 1 would be stored in input
location 5, the temperature from channel 2 in
input location 6, etc.
Detailed descriptions of the instructions are
given in Sections 9-12. Entering an instruction
into a program table is described in OV5.
OV4.3 ENTERING A PROGRAM
Programs are entered into the CR23X in one of
three ways:
1. Keyed in using the CR23X keypad.
2. Loaded from a pre-recorded listing using
the
D
Mode. There are 2 types of
storage/input:
a. Stored on disk/sent from computer.
b. Stored/loaded from Storage Module.
3. Loaded from internal Flash Memory or
Storage Module upon power-up.
A program is created by keying it directly into
the datalogger as described in Section OV5, or
on a PC using PC208W.
Program files (.DLD) can be downloaded directly
to the CR23X using PC208W. Communication
via direct wire, telephone, cellular phone, or
Radio Frequency (RF) is supported.
Programs on disk can be copied to a Storage
Module with the appropriate software. Using the
D
Mode to save or load a program from a
Storage Module is described in Section 1.8.
Once a program is loaded in the CR23X, the
program will be stored in flash memory and will
automatically be loaded and run when the
datalogger is powered-up.
The program on power up function can also be
achieved by using a Storage Module. Up to 8
programs can be stored in the Storage Module,
the programs may be assigned any of the
numbers 1-8. If the Storage Module is
connected when the CR23X is powered-up the
CR23X will automatically load program number
8, provided that a program 8 is loaded in the
Storage Module (Section 1.8). The program
from the Storage Module will replace the active
program in flash memory.
OV5. PROGRAMMING EXAMPLES
The following examples stress direct interaction
with the CR23X using the keypad. At the
beginning of each example is an EDLOG listing
of the program. You can also participate in the
example by entering the program in EDLOG
and sending it to the CR23X and viewing
measurements with PC208W. (See the
PC208W manual for guidance.) You can also
work through the examples with the 16 key
keypad. You will learn the basics of CR23X
operation as well as an appreciation for the
help provided by the software.
We will start with a simple programming
example. There is a brief explanation of each
step to help you follow the logic. When the
example uses an instruction, press
D
on
parameters marked with "?" for parameter
descriptions. Alternatively, find the instruction
on the Prompt Sheet and follow through the
description of the parameters. Using the
Prompt Sheet or on-line help while going
through these examples will help you become
familiar with their respective formats. Sections
9-12 have more detailed descriptions of the
instructions.
Turn on the CR23X. The programming steps in
the following examples use the keystrokes
possible on the keypad. With a terminal, some
responses will be slightly different.
When the CR23X is powered up, the display
will show:
