CO
FUNCTION: Configure Outputs
DESCRIPTION:
The CO command configures the extended I/O in blocks of 8.
ARGUMENTS: CO n
where
n is a decimal value which represents a binary number. Each bit of the binary number
represents one block of extended I/O. When set to 1, the corresponding block is
configured as an output.
configured as an output.
The least significant bit represents block 2 and the most significant bit represents block 9.
The decimal value can be calculated by the following formula. n = n
2
+ 2*n
3
+ 4*n
4
+
8*n
5
+16* n
6
+32* n
7
+64* n
8
+128* n
9
where n
x
represents the block. To configure a
block as an output block, substitute a one into that n
x
in the formula. If the n
x
value is a
zero, then the block of 8 I/O points will be configured as an input. For example, if block
3 and 4 is to be configured as an output, CO 6 is issued.
