Opto22 Mistic® Systems Overview

The removable brain board contains a microprocessor that communicates with a Mistic processor or with a host computer equipped with the proper interface card.  The brain board controls the plug-in I/O modules located on the I/O mounting rack.

Any combination of analog I/O modules may be plugged into an analog I/O unit and likewise, any combination of digital I/O modules may be plugged into a digital I/O unit.  Remote analog and digital I/O units can then be combined on the same RS-485 serial data link providing endless combinations of analog and digital I/O points.  In a similar way, any combination of local analog and digital I/O units can be combined on the same parallel data link.

Local analog and digital I/O units use flat ribbon cable for interconnections.  The maximum cable length for local I/O units is 200 feet.  Local units should be used within the same equipment rack or enclosure where cable runs can be kept short.  The primary reason for choosing local I/O units (rather than remote) is the much higher bus speed of 1.4 MHz.  The remote bus speed is 115 kHz.  The higher speed of the local I/O unit allows data to be sent and received in a much shorter time interval. This is very important for real-time control applications.

Remote I/O units communicate with the host computer over an RS-485 serial communications link.  The serial data link is composed of two twisted-pairs of cable (4 wires) that connect to each I/O unit.  One pair carries commands and responses and the other pair is used for a hardware interrupt from the I/O units.  It is possible to communicate with up to 256 individual I/O units on a single serial link for a total of 4,096 digital and analog I/O points.

The RS-485 data link offers excellent noise immunity and long cable lengths.  The maximum cable length for remote I/O units is 3,000 feet.  Wiring costs are reduced by eliminating the need for bringing large bundles of field wiring back to a central controller.  Remote I/O units can be located where the actual control is needed.
