Measurement Results for Which Output Is Possible (Character Inspection)

The following values can be output using processing items related to results output. It is also possible to reference measurement values from expressions and other processing units.

Measurement items	Character string	Description
Judgement	JG	Judgement result
Number of Characters	NUM	Chara. Num
NG cause	NG	NG cause
For following items, additional expression data with 32 characters is allocated for each character. (* represents the character number.)
Unit No.*	CUNO*	Detected unit No. for the *th character
Index No.*	CINDEX*	Detected index number for the *th character
Model No.*	CMODEL*	Detected model number for the *th character
Character code*	CCHAR*	Character code for the *th character "User's Manual", "Character Code Table"
NG Cause *	CNG*	NG cause for the *th character

About Output at PLC Link

About output of character inspection

If PLC link communication is performed, selecting the "Character output" check box among the output parameters for character inspection will cause character string data to be output to the PLC link output area. (FZ3 Ver. 2.10 or later)
If 32 characters are read (read character string: 0123456789...UV), a continuous ASCII code data string is output as shown below.

Output area

Top channel	Name	Output contents
+0ch	1st character, 2nd character	3031 (ASCII code corresponding to character "0," ASCII code corresponding to character "1")
+1ch	3rd character, 4th character	3233 (ASCII code corresponding to character "2," ASCII code corresponding to character "3")
･･･
+15ch	31st character, 32nd character	5556 (ASCII code corresponding to character "U," ASCII code corresponding to character "V")

How to receive character string data
As you do when serial data is output via PLC link, control the DSA data output request bit and GATE data completion request bit.
Since the entire character string comprises 1 data, DSA control is performed once if there is only 1 character inspection unit.
