Facts and Change
Unity Momentum 171CBU*****
Causes and Fixes
Located variables cannot be assigned to the Momentum IO as in Concept.
Typically, the hardware configuration information is stored in %KW words for the Unity PLC's. Due to the hardware
limitation, the use of %KW words is not allowed for the Momentum PLC. As a result, Unity is forced to use reserved
%MW words for the module configuration information. The %MW words used for the configuartion are intentionally
locked out to prevent the user from changing the values. This also locks out the the use of a %MW assignment for the IO.
