The transmission status of user mail, periodic mail, and error log mail are stored in this word as shown in the following table.

	Bits		Status
02	01	00
06	05	04
10	09	08
14	13	12
OFF	OFF	OFF	Mail is either waiting to be sent or can be sent using the Mail
			Send Switch. No mail is being sent.
OFF	OFF	ON	Mail is being sent.
OFF	ON	OFF	Mail is either waiting to be sent or can be sent using the Mail
			Send Switch. The previous mail transmission was completed
			normally.
ON	ON	OFF	Mail is either waiting to be sent or can be sent using the Mail
			Send Switch. An error occurred in the previous mail transmis-
			sion.
ON	ON	ON	Mail cannot be sent (system setting error).

While mail is being sent, the transmission status of the three bits each for send condition settings 1 to 8, i.e., bits 02, 01, and 00; bits 06, 05, and 04; or bits 10, 09, an 08 are 0, 0, and 1 respectively. After the transmission has been completed normally, they become 0, 1, and 0. If the transmission is ended with an error, they become 1, 1, and 0.

Check this transmission status in the ladder program as required.
