Module type Size Direction
Big Input 509 bytes O→T
Big Output 505 bytes T→O
By generating multiple module devices and setting module types, data structure can
be created within cyclic data.
Example) T→O data: 8 bytes, O→T data: 6 bytes
● The maximum data length within a single connection point is as follows:
O→T data: 509 bytes
T→O data: 505 bytes
2-2 There is no need to set all items in (2), as values cannot be entered.
3. In the "EtherNet/IP Module I/O Mapping
" tab, map data to variables in the application POU,
as below.
3-1 In the POU, create variables to which data is to be mapped.
3-2 Map I/O data to each variable that has been created. Double-click the section
indicated by (1) and select a variable to which I/O data is to be mapped.
13.4.8 EtherNet/IP Adapter Operation
When a project in which EtherNet/IP adapter settings have been configured is downloaded to
the GM1 controller and then RUN mode is invoked, the adapter device responds to a
ForwordOpen packet from the scanner device and cyclic communication is started.
