ProNet-80 connects up to 240 Unibus or Multibus
workstations using any combination of shielded twisted-pair or fiber-optic cabling.
In addition to Eagle and Eagle 21, the move will allow plants to maintain other safety systems using any of the Multibus
I product line, such as reactor vessel level instrumentation, neutron flux monitoring, and plant safety monitoring.
Depending on the application, features of the controls include: electro-luminescent or LCD operator displays, high-speed event detection for real-time response, high-density/high-power digital I/O, analog I/O, closed-loop control, alarm and fault detection and display, on-board diagnostics, Multibus
or ISA bus architecture, 386 microprocessors, DOS platform, plotting and graphics, real-time clock, soft keys, printer output, and auxiliary-equipment interface.
Among the several available backplane buses were Multibus
I and II, VME, Nu-Bus, Future Bus/Future Bus + and PI Bus.
Today's networks have evolved employing multibus
technologies and methodologies, with expandable multi-processors that serve many hosts.
acquisition is supported across a wide range of processor, memory, and general-purpose bus types through preprocessors available from Tektronix and partners New Wave and Nexus Technology.
