Mail Send Function Details Section 2-2
• Since the Ethernet Unit creates the data file automatically, the Accessing
Memory/Sending Mail Flag (bit 01 of n+17 in the allocated CPU Bus Unit
Area) will be ON while the CPU Unit's I/O memory is being accessed.
• To maintain the integrity of the data, write-protect the region of I/O mem-
ory being converted to a data file by preventing the region from being writ-
ten from the ladder program while this flag is ON.
File Data (1 MB Max.) Any file stored in the Memory Card installed in the CPU Unit (root directory
MEMCARD) can be sent with the e-mail as an attached file.
• Generally, CS/CJ file memory files are attached, such as program files
(.OBJ), parameter files (.STD), and data files stored in the Memory Card
(.IOM, .TXT, or .CSV).
