COMMAND Contains the value 15.
ADDRESS

POSITION Contains the point number.
VALUE ARRAY
The first element of this array contains a 0 if the point will be configured as an
input, or anything else if the point will be configured as an output.
R
EMARKS
:
All output module positions must first be configured as outputs before values can be written to
them. The driver will ignore any write commands to positions configured as inputs and no errors
will be returned.
The POSITION value is a point offset starting from the value in the ADDRESS parameter. The point
number in the POSITION parameter can range from 0 to 511 if the ADDRESS parameter is 0. An
error will be returned if the values in these parameters exceed the limits.
E
XAMPLE

This example configures point 0 at address 1 as an output.
