Can I connect multiple OITs to one PLC?

Yes, the OITs connect together in a daisychain fashion. One of the OITs is designated as the ‘master’ while the other OITs are defined as ‘slaves’. The master OIT is directly connected to the PLC communications port. Each slave OIT then communicates through the master OIT to get data from the PLC. No additional communications modules are required which provides an effective and inexpensive way to connect multiple OITs to a single PLC.
