Command Setting Example
This example shows how to set Message communication command strings.
• For the data that is sent from the PLC to the code reader, set a serial command character string.
•
When using K Commands there is no Response. In other words, there is no data to receive after
sending the command.
However, in the case of a Verify setting command like <K225?>, there is a Response so data will be
received after this command type is sent.
Example 1: The received data string when the data was sent using the <K225,0> command.
(Transmitted data) in 7 bytes 0x3C('<') 0x32('2') 0x32('2') 0x35('5') 0x2C(',') 0x30('0') 0x3E('>')
(Received data) None
Example 2: The received data string when the data was sent using the <K225?> command.
(Received data) in 6 bytes 0x3C('<') 0x32('2') 0x32('2') 0x35('5') 0x32('?')0x3E('>')
(Transmitted data) in 7 bytes 0x3C('<') 0x32('2') 0x32('2') 0x35('5') 0x2C(',') 0x30('0') 0x3E('>')
