Outputting Read Characters to an External Device

After a measurement, you can automatically output the character string that was read with the barcode
inspection item to a PLC or other external device. The character strings are output after outputting the output
data (output data settings 0 to 31), such as the inspection item parameters and calculation result.
Refer to the description for the communications format for the setting procedure and output specifications to
output the character string.

• Section 3 Controlling Operation and Outputting Data with an Ethernet Connection
• Section 4 Controlling Operation and Outputting Data with an RS-232C Connection
Note
The read character string is output after the other output data (data 0 to 31 in the output data settings) after the mea-
surement, such as the inspection item parameters and calculation results.
Refer to the following section for the location of the output area for the character string and other details.
