Software compatibility: Network transparency
Introduction
Transparency restrictions
Exchanges from a remote station to the FIPIO bus or vice versa are possible under certain conditions.
Inter-station communication with FIPIO is only available if the bus arbiter is a
Premium PLC, of at least version V3.3.
Exchanges from a third-party device to a PLC connected as a FIPIO slave are only possible if the PLC is a Premium of V3.3 at least. Communication with a Micro PLC is not possible.
A FIPIO agent does not communicate with the exterior.
Only one programming terminal can be connected to the FIPIO bus. If it is present in the configuration, it must be connected to the default connection port (63).
This programming terminal cannot be used to load the application onto the FIPIO bus arbiter.
