It supports multi-channel I\/O configurations and reduces individual field-wire routing to the I\/O assembly. The module bus connection can use Optical ModuleBus or a Cluster Modem arrangement according to the system configuration.\u003c\/p\u003e\n\u003cp\u003eThe TU850 itself is a termination unit rather than a PLC CPU, communication processor, or Ethernet interface.
