27. the mode priority evaluation For example a CPU is in RUN IO ENABLED mode and a Service Request 13 function block is executed to place the CPU into STOP IO DISABLED mode Before the transition to STOP IO DISABLED is completed the RUN STOP switch is changed from RUN IO ENABLED to RUN IO DISABLED In this case the CPU ignores the new request from the RUN STOP switch to go to RUN IO DISABLED mode because it is already processing a request to go to STOP IO DISABLED mode and STOP mode has a higher priority than RUN mode Suspend IO Function Block does not In a Series 90 70 the SUSPEND_IO function block suspends Suspend EGD EGD in addition to IO Scan In PACSystems controllers the SUSPEND IO only suspends IO Scan Installation in Hazardous Locations The following information is for products bearing the UL marking for Hazardous Locations WARNING EXPLOSION HAZARD SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY FOR CLASS I DIVISION 2 WARNING EXPLOSION HAZARD WHEN IN HAZARDOUS LOCATIONS TURN OFF POWER BEFORE REPLACING OR WIRING MODULES AND WARNING EXPLOSION HAZARD DO NOT CONNECT OR DISCONNECT EQUIPMENT UNLESS POWER HAS BEEN SWITCHED OFF OR THE AREA IS KNOWN TO BE NONHAZARDOUS EQUIPMENT LABELED WITH REFERENCE TO CLASS I GROUPS A B C amp D DIV 2 HAZARDOUS LOCATIONS IS SUITABLE FOR USE IN CLASS DIVISION 2 GROUPS A B C DOR NON HAZARDOUS LOCATIONS ONLY The tightening torque range for the control t
