Block Diagram AB CONTROLLOGIX – SYSTEM OPERATION AND PROGRAMMING COURSE This is because the FBD not allow the instruction to have two or more Output reference with same Tag The FBD Data flows from output block to the next wired input block 1.2 Latching Data 1.2.A Create Instruction example and verify controller Instruction example 1.2.B Download to the controller Before Download to the controller, make sure that the controller path and controller slot (in the controller properties) is true Lab Works Function Block Diagram AB CONTROLLOGIX – SYSTEM OPERATION AND PROGRAMMING COURSE 1.2.C Run Controller Watch that the Analog_Value_1, both in input reference and in output reference have the same value The FBD Latch the data until next scan execute 1.3 Assume Data Available 1.3.A Create Instruction example and verify controller ADD_01 ADD Add 0.0 SourceA Dest Analog_Value_1 SourceB Analog_Value_1 ADD_02 ADD Add 1 0.0 SourceA Dest Analog_Value_2 SourceB Instruction example 1.3.B Download to the controller and then run processor Lab Works Function Block Diagram AB CONTROLLOGIX – SYSTEM OPERATION AND PROGRAMMING COURSE Two instructions give the same mean The assume data available uses an output that the block produced on the previous scan Or in other word we can create delay with this 1.3.C Create Instruction example and verify controller ADD_01 ADD MUL_01 MUL Add Multiply 1 0.0 SourceA 0.0 Dest SourceA SourceB Dest Analog_Value_2 SourceB 1 1.3.D Download to controller and then run The Assume data available use above is to produce a one scan delay between blocks Lab Works Function Block Diagram AB CONTROLLOGIX – SYSTEM OPERATION AND PROGRAMMING COURSE The assume data available can create delay between block 1.2 Exercise 1, BIT Instruction 1.2.A Create

question: A Close Switch_0 (By toggle the Tag), When Switch_0 is Close (Bit = 1), which Tag/Light(s) is turn on? B Open Switch_0 When Switch_0 is Open what happen to Light_0 and Light_1? C Close Switch_1 What happens to the Light_2? D Open Switch_1 What happens? E Close Switch_2 What happens? F Open Switch_2 What happens? G What must you to turn the Light_3 off? H What happens if we close Switch_2 and Switch_3 (Correspond to Light_3)?
