Attachment
For attachments, the data format can be selected as either ASCII code (ASCII format or CSV format) or binary code (binary
format).
The following figure shows what is sent for each data format (binary, ASCII, or CSV) when the Ethernet module sends the
values of D0 to D100, from the start address D0, as an attachment.
D0 1234H
D1 5678H
·
D100 9ABCH
■Structure of data in CSV format
Data in CSV format can be used for data management on a cell basis by Excel.
The following shows data in CSV format handled by the Ethernet module.
• Each word of binary data (16 bits) is converted into a 4-digit ASCII code expressed in hexadecimal (4 bytes of ASCII code).
• When handling multiple words of data, a comma is inserted after every 1 word (4 bytes of ASCII data).
• Besides the above data conversion and insertion, CR (Code: 0DH) and LF (Code: 0AH) are inserted after every 8 words of
data.
The target data are sent in the following order.
