To input an instruction with its function code, press FUN, the function code, andthen WRITE. Refer to the pages listed programming and instruction details.CodeMnemonicName—ANDAND—AND LDAND LOAD—AND NOTAND NOT—CNTCOUNTER—LDLOAD—LD NOTLOAD NOT—OROR—OR LDOR LOAD—OR NOTOR NOT—OUTOUTPUT—OUT NOTOUTPUT NOT—RSET—FunctionPageLogically ANDs status of designated bit with execution condition.Logically ANDs results of preceding blocks.346Logically ANDs inverse of designated bit with executioncondition.A decrementing counter.346Used to start instruction line with the status of the designatedbit or to define a logic block for use with AND LD and OR LD.Used to start instruction line with inverse of designated bit.346Logically ORs status of designated bit with execution condition.Logically ORs results of preceding blocks.346Logically ORs inverse of designated bit with execution condition.Turns ON operand bit for ON execution condition; turns OFFoperand bit for OFF execution condition.Turns operand bit OFF for ON execution condition; turns operand bit ON for OFF execution condition (i.e., inverts operation).346RESETTurns the operand bit OFF when the execution condition isON, and does not affect the status of the operand bit whenthe execution condition is OFF.348SETSETTurns the operand bit ON when the execution condition isON, and does not affect the status of the operand bit whenthe execution condition is OFF.348—TIMTIMERON-delay (decrementing) timer operation.35900NOPNO OPERATIONNothing is executed and program moves to next instruction.35101ENDEND35102ILINTERLOCK03ILCINTERLOCK CLEAR040506JMPJME(@)FAL07FALS08STEPJUMPJUMP ENDFAILURE ALARM ANDRESETSEVERE FAILUREALARMSTEP DEFINERequired at the end of the program.If interlock condition is OFF, all outputs are turned OFF andall timer PVs reset between this IL(02) and the next ILC(03).Other instructions are treated as NOP; counter PVs aremaintained.If jump condition is OFF, all instructions between JMP(04)and the corresponding JME(05) are ignored.09SNXTSTEP START10SFT11KEEP1213Generates a non-fatal error and outputs the designated FALnumber to the Programming Console.Generates a fatal error and outputs the designated FALSnumber to the Programming Console.When used with a control bit, defines the start of a new stepand resets the previous step.
