This renders a read/write access by means of the reference and the Intellisense function to the data
contents of the ACD structure possible:

9.2.4 The structure MachineModuleData (MMD)
The MachineModuleData structure (MMD) of the MMD_scModulname type serves to instance
machine module data.
• The ApplicationTemplate PackML contains variables and function blocks for instancing machine
module data.
• All module applications (MAPs) of a machine module can access this MMD structure.
The data structure inherits the L_EATP_MMD_Base structure contained in the
L_EATP_ApplicationTemplate library.

• The MMD_sc can be individually extended by the data types and function blocks
required.
• In the structure, the L_EATP_CriticalSection block which ensures a consistent data exchange is
instanced (if the block is used correctly).

Note!
In contrast to the ACD structure, the higher-level master module cannot access the MMD
structure!
