Direct data mapping
By default, parameters
MM.010
to
MM.029
are used as pointers to specify the
destination parameter for OUT data received from the Interbus master controller, and
the source parameter of IN data to be transmitted to the Interbus master controller.
When direct data mapping is enabled, Pr
MM.010
to Pr
MM.019
are used as the source
parameters for IN data and Pr
MM.020
to Pr
MM.029
are used as the destination
parameters for OUT data.
Hence, IN data values read from Pr
MM.010
to
MM.019
will be transmitted to the
Interbus master controller and OUT data values arriving from the Interbus master
controller will be written directly into Pr
MM.020
to Pr
MM.029
.
14.7
Cyclic input mapping
The reference for the source parameter is entered in the mapping parameter in the form
MMPP, where MM represents the menu number of the source parameter and PP
represents the parameter number of the source parameter. Leading zeros are not
displayed.
