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.
