I/O architectures
Remote I/O (RIO)
electrically isolate the drop from the trunk cable and to protect the system from
impedance mismatches and cable disconnections. A minimum signal strength
of 14 dB is required between the trunk cable and each I/O drop to help ensure
correct operation. The signal loss on the trunk cable is less than 1 dB as it crosses
a T-connector. A total of 35 dB is available from the head-end RIO CPU. The whole
cabling architecture must not exceed this system limit.
For systems that require high availability, a solution with redundant cable is
available, to provide protection against cable breaks and damaged connectors. With
two cables connected between the host and each drop, the first cable break does not
disrupt communication. If a cable break occurs, a status bit is set to 1 to indicate the
problem drop or the faulty cable. For preventive maintenance, the system also
provides retry counters for all communication transactions to all drops. High retry
counts on a cable in a specific drop could indicate connection problems. This will
enable corrective work to be scheduled before there is unwanted downtime.
