OV4.2 KEY DEFINITION

Keys and key sequences have specific functions when using the CR10KD keyboard or a computer/terminal in the remote keyboard state (Section 5). Table OV4-2 lists these functions. In some cases, the exact action of a key depends on the mode the CR10 is in and is described with the mode in the manual.

#Clear the rightmost digit keyed into the display

#A	Advance to next instruction in
	program table (*1, *2, *3) or to next
	Output Array in Final Storage (*7)
#B	Back up to previous instruction in

#D	Delete entire instruction
#0	(then A or CR) Back up to the start of
	the current array.

When using a computer/terminal to communicate with the CR10 (Telecommunications) there are

OV4.3 PROGRAMMING SEQUENCE

In routine applications, the CR10 measures sensor output signals, processes the measurements over some time interval and stores the processed results. A generalized programming sequence is:

1.Enter the execution interval. In most cases, the execution interval is determined by the desired sensor scan rate.

2.Enter the Input/Output instructions required to measure the sensors.

3.If processing in addition to that provided by the Output Processing Instructions (step 5) is required, enter the appropriate Processing Instructions.

4.Enter the Program Control Instruction to test the output condition and set the Output Flag when the condition is met. For example, use

Instruction 92 to output based on time.

Instruction 86 to output every execution interval.

Instruction 88 or 89 to output based on a comparison of values in input locations.

This instruction must precede the Output Processing Instructions which store data in Final Storage. Instructions are described in Sections 9 through 12.

5.Enter the Output Processing Instructions to store processed data in Final Storage. The order in which data are stored is
