UL W a i t for I/O low
Usage I I IMM • PGM L i MIP
Syntax x x U L
Parameters
Description x x [int] — I / O bit number.
Range x x — 0 to 8.
Units x x N o n e .
Defaults x x M i s s i n g : 0 .
Out of range: E r r o r E.
Floating point: E r r o r A.
Description T h i s command causes a program to wait until a selected I/O input bit
becomes low. It is level, not edge sensitive which means that at the time of
evaluation, if the specified I/O bit xx is low already, the program
will con-
tinue executing.
If the bit specifier xx is missing or set to 0, the program
will wait for all bits
to be low.
NOTE
The command can be placed on a line by itself or with other commands.
If placed on a line with other commands, the advantage is that they will
be executed with a minimal delay after the I/O bit goes low.
Returns N o n e .
Errors A U n k n o w n message code.
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.
Rel. Commands U H — W a i t for I/O high.
Example
7UL, 3PA12.3 I W a i t while bit #7 of the I/O input port becomes low and then move
axis #3 to position 12.3 units and continue the rest of the program.
