Object PmaCommMsg (Communication message)
Description:
See:
PmaCommMsg - Deatiled object description
The object serves to the definition of the format and data of one communication message.
No other
Pma objects can be created in this object.
The
PmaCommMsg object can be created only in the
PmaComm object (if the selected protocol supports the usage of the
PmaCommMsg object). There can be even more
PmaCommMsg objects in the
PmaComm object.
This object
adds variables into the calculation of the application size, which influences the
basic runtime licence type/size (see:
