[Function] Write the character string in the column specified in operand 2 to the channel specified in
operand 1.
The operation will end when the character specified by a SCHA command is written.
Either a local or global column can be specified.
[Example] SCHA 10 Set LF (= 10) as the end character.
OPEN 1 Open channel 1.
WRIT 1 2 Write the character string in column 2 to channel 1
until LF is written.
CLOS 1 Close the channel.
(Note 1) If the main application version is 0.41 or later, the “Forcibly enable receive immediately
before send” function is available when expanded SIOs (channel 2 and onward; optional) are
used via RS232C or RS422 (this function can be cancelled via parameter). If this function is
used, the X-SEL can receive a response from the other side without delay after a send.
(Note 2) If expanded SIOs (channel 2 and onward; optional) are used via RS232C or RS422, once
OPEN is executed those tasks other than the open ones can also be used to execute WRIT
(send). Therefore, the X-SEL can receive a response from the other side without delay after
a send, by executing READ with an open task and then WRIT with other task.
(Note 3) If expanded SIOs (channel 2 and onward; optional) are used via RS485, or when standard
SIOs (channel 1; also used by the teaching pendant) are used, the “Forcibly enable receive
immediately before send” function is available. However, using this function will generate a
delay time (the function can be cancelled via parameter). A minimum delay of 3 msec is
required after the X-SEL executes a send before it receives a response from the other side.
