Syntax x x R B
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 reads the I/O input port. If xx is specified between 1 and 8,
the return is either 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 bits. The return is a decimal number in ASCII format representing
the I/O byte. To find the values of each bit, the number must be converted
to binary.
NOTE
For the hardware definition of the I / O port, please see Appendix B,
Connector Pinouts, GPIO Connector.
Returns x x R B n n , ORBnn1, or RBnn2
xx — I / O bit number.
nn — I / O bit value, 0 or 1.
nni, nn2
— I / O byte value, 0 to 255 in ASCII format.
Errors A —
E —
S —
Unknown message code.
Incorrect I/O channel number.
Communication time-out.
Rel. Commands R A — R e a d analog input.
Example O R B I R e a d all 8 bits of the I/O input port.
RB209 I Controller returns a value o f 209, which converted to binary gives us
the following 1/0 input port status:
bit 8 b i t 7 b i t 6 b i t 5 b i t 4 b i t 3 b i t 2 b i t I
