5 COMMUNICATION PROCEDURE
5.5 Open Settings
This section explains the open setting.
A sequence program can perform open processing (establishing connection) with up to
a maximum of 8 external device stations
Once a connection is established with an external device, it is possible to communicate
using MC protocol, fixed buffer communication.
Thus, the open processing is required even when communicating using MC protocol.
NOTE
When adjusting settings in FX Configurator-EN (GX Developer), select the [Open
Settings] from the initial screen and adjust the settings at the [Ethernet Open
Settings] screen.
