5.3.1 I/O Mapping

This shows the mapping of the EtherCAT logic process data and the I/O registers of the MP2000 Series Machine Con-
troller.
The EtherCAT logic process data space used by the 264IF-01 Module is decided in advance by configuration at the
master node. The position within the Ethernet packets flowing in the network at which the I/O data of a 264IF-01 Mod-
ule is positioned is automatically managed by the communication IC installed in the 264IF-01 Module. This means
that, with the 264IF-01 Module, data can be refreshed just by setting the I/O size, without any awareness of the map-
ping (addresses of the data) of the logic process data of the master node.

Module
Mapping of EtherCAT logic process data is
performed inside the 264IF-01 Module,
and the data of input registers and output
registers is refreshed.
Input register
Only the master
side output data can
be taken into the
controller CPU.
