Output Format
Take the following case as an example.
Number of measurement is one. Reading character string is 32. Command: Read character strings
0123456789...UV, Command, Response, and Data Output area are as follows.
In this case, the following conditions are applied.
[Reading character output] is checked.
[Character count output] and [Error character output] are unchecked.

Data Output Area (Sensor Controller to PLC)
When read the 32 character strings (0123456789...UV), the result continues as follows.

Note
• If no character string, data is not output and no updating of data.
When check the [Error character output], output the error character string + NULL(0x00).
• When the character string is 2 bytes, i.e. Shift-JIS. the maximum number of character string is 16. Outputs one
character per one channel.
