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