A.4 Required memory for function blocks
A.4 Required memory for function blocks
The memory required for unconnected function blocks is the same for all pro-
gramming languages.
Each function block will reserve the memory space listed below when unconnected.
In addition, text function block D has extensive static operating parameters that
require additional memory space. Some modules require additional system para-
meters that are created once when the 1st instance is used.
