Distribution
Distribution of I/O capability can be easily achieved with the G3 platform by means of Sub-Bus modules. I/O
modules, valve manifolds and/or a combination of both can be simply separated from the main manifold and
distributed via a sub-bus communication cable. The G3 platform uses the same I/O modules on the main
manifold as on the distribution chain. The main communication module can control up to 16 I/O modules
either on the main manifold or as part of the sub-bus connections. To utilize the sub-bus distribution
capabilities the Sub-Bus OUT module must be located on the end of the main communication manifold and a
Terminator Module must be located at the last sub-bus component.
