Cannot assign a fieldbus function block to the H1 card

Certain restrictions and requirements must be met before a DeltaV function block can be assigned to run in the Series 2 H1 card. The topic on automatically assigning function blocks to the H1 card explains the restrictions and requirements and provides examples to help you configure modules to meet the requirements. The examples provide explanations of how to properly set the function block execution order. Function block execution order is set from Control Studio.
