Syntax x x W H n n
Parameters
Description x x [ i n t ] I / O input bit number.
nn [ i n t ] — I / O input bit or byte state.
Range x x — 0 to 8.
nn — 0 to 1 or 0 to 255.
Units x x — None.
nn N o n e .
Defaults x x M i s s i n g : E r r o r E.
Out of range: E r r o r E.
Floating point: E r r o r A.
nn M i s s i n g : 0 .
Out of range: 1 for a bit, error C for a byte.
Description T h i s command starts a WHILE loop based on the state of an I/O input bit or
byte. While the state of the selected I/O input bit xx is equal to nn, all fol-
lowing commands up to the corresponding WE are executed. The loop is
repeated until the test becomes false. At that point, the program executed
continues with the line immediately following the WE command.
If xx is set to 0 or missing, the test is performed on the entire I/O input byte
and then
nn could have a value from 0 to 255, representing the byte value
to compare it with.
NOTE
If the command is set to look for a bit by specifying xx between 1 and 8,
a non-zero value for the nn parameter will be considered as a I and the
while loop will execute until the I/O bit becomes Low.
Returns N o n e .
Errors A U n k n o w n message code.
C — Parameter out of limits.
E — I n c o r r e c t I/O channel number.
J — C o m m a n d authorized only in Programing mode.
L — C o m m a n d not at the beginning of a line.

WL —
WY — End While loop.
While variable greater than value.
While variable is less.
While variable is different.
