FUNCTION CODE BLOCK ADDRESS (OR BLOCK NUMBER)

A Block Address is a reference number for a function block and is assigned during configuration. The output values from one function block may be referenced as inputs to other function blocks by using its block number. For function codes that have two or more outputs, each output is referenced by a unique, sequential block address starting with the block number chosen during configuration. Block numbers may NOT be duplicated in the same master module or Command Series Controller configuration.
