[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.
