Get or set parameters
8.8.1
Get a parameter
To get the value of a parameter, enter the parameter number in
the
Command Request.
The Command Response Parameter
returned will contain the value of the parameter.
8.8.2
Set a parameter
To set the value of a parameter, enter the value of the parameter
into the
Command Request Parameter.
Then enter the parameter
number OR’ed with 0x1000 (Write) into the
Command Request.
The
Command Response
returned will be either success or an
error code. A common reason for getting an error is the value is
not in range.
8.9
Analog outputs scaling
Each analog output’s values for zero tension and maximum
tension can be set by the following parameters. The default for
the 0 to 20mA outputs is 0 and 20mA. Use these parameters to
scale the 0 to 20mA output to be 4 to 20mA. Put the new value of
the parameter into the Command Request Parameter before
issuing the parameter number OR’ed with Write (0x1000) in the
Command Request.
