4-3 Programming Console Operations

4-3-1 Overview

The following table lists the programming and monitoring operations that can be performed from a Programming Console. Refer to the rest of this section for details on operational procedures.

Name	Function	Page
Clearing memory	Clears all or part of the Program Memory and any data areas that are not	81
	read-only, as well as the contents of the Programming Console’s memory.
Reading/clearing error	Displays and clears error messages and displays MESSAGE instruction	82
messages	messages.
Buzzer operation	Turns ON and OFF the buzzer that sounds when Programming Console keys	82
	are pressed.
Setting a program memory	Sets the specified program memory address when reading, writing, inserting	83
address	and deleting programs.
Reading a program memory	Reads the contents of the Program Memory. Displays the status of the	83
address/monitoring bit status	currently displayed bit in PROGRAM and MONITOR modes.
Instruction search	Finds occurrences of the specified instruction in the program.	87
Bit operand search	Finds occurrences of the specified operand bit in the program.	87
Inserting and deleting	Inserts or deletes instructions from the program.	88
instructions
Entering or editing programs	Overwrites the contents of the current Program Memory to either input a	84
	program for the first time or to change a program that already exists.
Checking the program	Checks for programming errors and displays the program address and error	89
	when errors are found.
Bit, digit, word monitor	Monitors the status of up to 16 bits and words, although only 3 can be shown	90
	on the display at one time.
Multiple address monitor	Monitors the status of up to 6 bits and words simultaneously.	91
Differentiation monitor	Monitors ON-to-OFF or OFF-to-ON changes in the status of a particular bit.	92
Binary monitor	Monitors the ON/OFF status of any word’s 16 bits.	92
Three-word monitor	Monitors the status of three consecutive words.	93
Signed decimal monitor	Converts the contents of the specified word from signed hexadecimal (two’s	94
	complement format) to signed decimal for display.
Unsigned decimal monitor	Converts hexadecimal data in a word to unsigned decimal for display.	94
Three-word data modification	Changes the contents of one or more of the 3 consecutive words displayed in	95
	the Three-word Monitor operation.
Changing timer, counter SV 1	Changes the SV of a timer or counter.	95
Changing timer, counter SV 2	Makes fine adjustment changes to the SV of the timer or counter.	96
Hexadecimal, BCD data	Changes the BCD or hexadecimal value of a word being monitored.	96
modification
Binary data modification	Changes the status of a word’s bits when the word is being monitored.	97
Signed decimal data	Changes the decimal value of a word being monitored as signed decimal data	98
modification	within a range of –32,768 to 32,767. The contents of the specified word are
	converted automatically to signed hexadecimal (two’s complement format.)
Unsigned decimal data	Changes the decimal value of a word being monitored as unsigned decimal	99
modification	data within a range of 0 to 65,535. A change to hexadecimal data is made
	automatically.
Force set/reset	Forces bits ON (force set) or OFF (force reset.)	99
Clear force set/reset	Restores the status of all bits which have been force set of reset.	100
Hex-ASCII display change	Converts word data displays back and forth between 4-digit hexadecimal data	100
	and ASCII.
Displaying the cycle time	Displays the current average cycle time (scan time.)	101
