    DESCRIPTION AND OPERATION ® other LIMs on the Plant Loop. LIMs can transmit and receive messages simultaneously at any time. There is no loop master or traffic director. LIM startup/shutdown is localized requiring no interaction with other LIMs on the loop. Each LIM receives all incoming messages and transmits a new stream of mes- sages in a store and forward fashion to the next LIM.

    The interface modules use CMOS devices. Follow the special handling procedures below: NOTE: Always use Bailey's Field Static Kit (P/N 198385A2 - con- sists of wrist strap, ground cord assembly, and alligator clip) when working with modules. The kit is designed to connect a technician and the static dissipative work surface to the same ground point to prevent damage to the modules by electrostatic discharge.
