Precautions for programming
● Insert the UNITSEL instruction immediately before this instruction and specify the unit (built-
in ET-LAN in the CPU unit) and the connection number.
● For [S1] and [S2], specify the starting address of the device area that stores the string data
that indicates the set parameters, or a character constant. When specifying a device area for
an operand, set string data using the SSET instruction in advance. However, the ESSET
instruction cannot be used because the format is different. Both upper and lower case
characters can be used. "Abcd", "ABCD" and "abcd" are all synonymous.
● This instruction is not available in interrupt programs.

Setting of the operands [S1] and [S2]
Setting item Settings
S1 Read type
When specifying FTP client Specify "FTPc".
When specifying HTTP client
Specify "HTTPc"
(Note 1)
When specifying mail transmission Specify "SMTPc".
S2 Read target
When specifying transfer numbers
individually
Specify "IDx" with x being a value from
0 to 15.
When specifying logging individually
Specify 0 to 15 for x with "LOGx"
(Note 1)
When specifying all transfer numbers Specify "IDALL".
When specifying all loggings
Specify "LOGALL"
(Note 1)
D
Read
destination
Specify the destination device address to which the state is read out.
(Note 1) When "HTTPc" is specified for [S1], neither "LOGx" nor "LOGALL" can be specified for [S2]. If one of
them is specified, an operation error occurs.
