(Note 1)
[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.
As long as a standard SIO port (channel 1 or 2) is open, a task other than the one that
opened the port can be used to execute (send) a WRIT command. Accordingly, if a READ
command is executed in a port-opening task and then a WRIT command is executed in other
task, the response from the other side can be received without delay after the command is
sent from the XSEL.
(Note 1) CP for channels other than 1 and 2.
Return code of the WRIT command (channels 1 and 2 only)
The return code is stored in a local variable. The variable number can be set by “Other parameter No. 24.”
The default variable number is 99.
0: WRIT completed successfully
1: WRIT timeout (the timeout value is set by a TMRW command)
2: WRIT timer cancelled (the wait status is cancelled by a TIMC command)
3 to 4: For future expansion
5: WRIT factor error (program abort error) (Cannot be recognized by SEL commands)
6: WRIT task ended (program end request, etc.) (Cannot be recognized by SEL commands)
