RO R e a d I/O output
Usage • IMM • PGM • MIP
Syntax x x R O
Parameters
Description x x [ i n t ] — 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 reads the I/O output port. If xx is specified between 1 and 8,
the return is ether 0 or 1. depending on the state of the selected I/O bit.
If the bit specifier
xx is missing or set to 0, the controller returns the values
for all 8 hits. The return is a decimal number in ASCII format representing
the I/O output byte. To find the values of each bit, the number must be con-
verted to binary.
NOTE
For the hardware definition of the I / O port, please see Appendix B,
Connector Pinouts, GPIO Connector.
Returns x x R O n n , OROnn1, or ROnn2
xx — I / O output bit number.
nn — I / O output bit value, 0 or 1.
nni, nn2
— I / O output byte value, 0 to 255 in ASCII format.
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.
S — Communication time-out.
Rel. Commands C B — C l e a r I/O outputs bits.
SB — S e t I/O output bits.
SO — S e t I/O output byte.
TG — To g g l e I/O output bits.
Example R O I R e a d the 1/0 output port.
R0209 I Controller returns a value of 209, which converted to binary gives us
the following 1/0 output port status:
