Basic Function <strong>Instruction</strong>FUN 0MCSymbolMATER CONTROL LOOP STARTFUN 0MCOperandN: Master Control Loop number (N=0~127)the number N cannot be used repeatedly.Description●●●There are a total of 128 MC loops (N=0~127). Every Master Control Start instruction, MC N, mustcorrespond to a Master Control End instruction, MCE N, which has the same loop number as MC N.They must always be used in pairs and you should also make sure that the MCE N instruction is after theMC N instruction.When the Master Control input "EN/" is 1, then this MC N instruction will not be executed, as it does notexist.When the Master Control input "EN/" is 0, the master control loop is active, the area between the MC Nand MCE N is called the Master Control active loop area. All the status of OUT coils or Timers withinMaster Control active loop area will be cleared to 0. Other instructions will not be executed.ExampleLadder Diagram Key Operations Mnemonic CodesX0X1EN0.MC 1Y0ORGORGFUNN:X010X21ST201 10ORGOUTORGOUTXY10T201Y1ORGORGX2X11.MCE 1Y2ORGOUTT201 PV:ORGOUTTY102011FUN1N:1ORGOUTORGOUTXY126-12
