Mapping Table
Mapping Table
Functionality:
The master can send 4 different frames (F1,... F4). A frame can be sent from
several slots:
Frame: F1 F2 F3 F4
possible slots: 0 ... 2 3 ... 7 8 ... 12 13 ... 17
Each frame is assigned a mapping table number.
The individual slaves read in the slot from where their relevant data are sent.
It is necessary to define a mapping table in the slave, stating where the individual
process data are to be written (e.g. into an array-object).
The assignment of the mapping table is made via the mapping table number which
is transferred via HEDA.
For this reason, the receive mapping table number and the transfer mapping table
number must always be the same.
Receive-Mapping-Tablen-Number = Transmit-Mapping-Table-Number
