The @ character represents a hard tab and displayed as a tab in text displays.

Note

The TXT file format is compatible with the CPU Unit's READ DATA FILE and

 

WRITE DATA FILE instructions (FREAD and FWRIT) set to tab-delimited

 

word format with a carriage return every 10 words.

CSV Format

When hexadecimal I/O memory data (1234, 5678, 9ABC, etc.) is being sent

 

as an attached file in CSV format, the data is stored with the following proce-

 

dure.

 

1.

The word data is converted to ASCII.

 

2.

The word data is delimited by commas (“,”: 2C).

 

3.

A return and line feed ([CR][LF]: 0D0A) are inserted after every 10 words.

2-7 Attached File Transfer Times

When sending an attached file with the Mail Send Function, the access time can be as long as 30 or 40 minutes for a very large file. The following tables show how long the CPU Unit's memory will be accessed by the Ethernet Unit (how long the Accessing Memory/Sending Mail Flag will be ON).
