EXPLICIT MESSAGING

The Pinnacle DeviceNet interface supports explicit messaging so that you can receive
information about two power system parameters: maximum power and maximum current. Use

Note: The Max Power attribute returns a value in Watts if the unit is operating stand alone. For
example, a value of 20,000 equates to 20,000 W. The Max Power attribute scaling is
Watts x 10 if the unit is operating as a master/slave set. In this case, a value of 2,000
equates to 20,000 W.
Note: The Max Current attribute returns a value in Amperes with 2 decimal places implied.
For example, a value of 8,000 equates to 80 A.
For more information about this type of messaging, refer to section 4-2 of the DeviceNet
Specification (version 2.0 or later). The following Common Services specifications apply:
