TD ADDENDUM-OVERVIEW 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. OV4.5 ENTERING A PROGRAM Programs are entered into the CR10X in one of two ways: 1. Keyed in using the CR10X keyboard 2. Stored on disk/seat from computer A program is created by keying it directly into the datalogger as described in Section OV5, or on a PC using EDLOG. description of the parameters. Using the Prompt Sheet while going through these examples will help you become familiar with its format. Sections 9-12 have more detailed descriptions of the instructions. With the Wiring Panel connected to the CR10X, hook up the power leads as described in Section OV1.2. Next, connect the CR10X to either a CR10KD Keyboard/Display or the computer (Section OV3). The programming steps in the following examples use the keystrokes possible on the keyboard/display. With a terminal, some responses will be slightly different. If the CR10KD is connected to the CR10X when it is powered up, the display will show: EDLOG is used to develop programs for Campbell Scientific CR10X dataloggers. EDLOG is a prompting editor for writing and documenting programs for Campbell Scientific CR10X dataloggers. Program files developed with EDLOG can be downloaded directly to the CR10X using NetAdmin. NetAdmin supports communication via direct wire, telephone, or Radio Frequency (RF). OV5. PROGRAMMING EXAMPLES Display HELLO Explanation On power-up, the CR10X displays "HELLO" while it checks the memory (this display occurs only with the CR10KD). after a few seconds delay :96 The size of the machine's total memory (RAM plus 32 K of ROM), in this case 96K 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, find it on the Prompt Sheet and follow through the OV5.1 SAMPLE PROGRAM 1 In this example the CR10X is programmed to read its own internal temperature (using a built in thermistor) every 5 seconds and to send the results to Final Storage. Key Display Explanation * 00:00 Enter mode. 1 01:00 Enter Program Table 1. A 01:0.0000 Advance to execution interval (In seconds) 5 01:5 Key in an execution interval of 5 seconds. A 01:P00 Enter the 5 second execution interval and advance to the first program instruction location. 17 01:P17 Key in Instruction 17 which directs the CR10X to measure the internal temperature in degrees C. This is an Input/Output Instruction. A 01:0000 Enter Instruction 17 and advance to the first parameter. 1 01:1 The input location to store the measurement, location 1. A 02:P00 Enter the location # and advance to the second program instruction. The CR10X is now programmed to read the internal temperature every 5 seconds and place the reading in Input Storage Location 1. The program can be compiled and the temperature displayed. AD-OV-3

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.

OV4.5

ENTERING A PROGRAM

Programs are entered into the CR10X in one of

two ways:

Keyed in using the CR10X keyboard

Stored on disk/seat from computer

A program is created by keying it directly into

the datalogger as described in Section OV5, or

on a PC using EDLOG.

EDLOG is used to develop programs for

Campbell Scientific CR10X dataloggers.

EDLOG is a prompting editor for writing and

documenting programs for Campbell Scientific

CR10X dataloggers.

Program files developed

with EDLOG can be downloaded directly to the

CR10X using NetAdmin.

NetAdmin supports

communication via direct wire, telephone, or

Radio Frequency (RF).

OV5.

PROGRAMMING EXAMPLES

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, find it on the

Prompt Sheet and follow through the

description of the parameters.

Using the

Prompt Sheet while going through these

examples will help you become familiar with its

format.

Sections 9-12 have more detailed

descriptions of the instructions.

With the Wiring Panel connected to the CR10X,

hook up the power leads as described in

Section OV1.2.

Next, connect the CR10X to

either a CR10KD Keyboard/Display or the

computer (Section OV3).

The programming

steps in the following examples use the

keystrokes possible on the keyboard/display.

With a terminal, some responses will be slightly

different.

If the CR10KD is connected to the CR10X when

it is powered up, the display will show:

Display

Explanation

HELLO

On power-up, the CR10X

displays "HELLO" while it checks

the memory (this display occurs

only with the CR10KD).

after a few seconds delay

The size of the machine's total

memory (RAM plus 32 K of

ROM), in this case 96K

OV5.1

SAMPLE PROGRAM 1

In this example the CR10X is programmed to

read its own internal temperature (using a built

in thermistor) every 5 seconds and to send the

results to Final Storage.

Key

Display

Explanation

00:00

Enter mode.

01:00

Enter Program Table 1.

01:0.0000

Advance to execution interval (In seconds)

01:5

Key in an execution interval of 5 seconds.

01:P00

Enter the 5 second execution interval and advance to

the first program instruction location.

01:P17

Key in Instruction 17 which directs the CR10X to

measure the internal temperature in degrees C.

This is

an Input/Output Instruction.

01:0000

Enter Instruction 17 and advance to the first parameter.

01:1

The input location to store the measurement, location 1.

02:P00

Enter the location # and advance to the second

program instruction.

The CR10X is now programmed to read the internal temperature every 5 seconds and place the reading

in Input Storage Location 1.

The program can be compiled and the temperature displayed.
