Programming LOGO! 3.2 Blocks and block numbers 3.2 Blocks and block numbers This chapter shows you how to use LOGO! elements to create complex circuits and how blocks and I/O are interconnected. In the topic "From circuit diagram to LOGO! program (Page 59)" you will learn how to transform a conventional circuit into a LOGO! circuit program. Blocks A block in LOGO! represents a function that is used to convert input information into output information.
Programming LOGO! 3.2 Blocks and block numbers Block representation on the LOGO! onboard display The figure below shows a typical view of the LOGO! onboard display. As you can see, it can show only one block at a time. LOGO! shows the block number on the top of the display by default if you assign no name to this block. The block numbers help you check the circuit structure. Alternatively, you can also choose to display a customized block name instead of the block number.
Programming LOGO! 3.3 From circuit diagram to LOGO! program Advantages of block numbers You can connect almost any block to an input of the current block by means of its block number. In this way, you can reuse the interim results of logical or other operations, reduce programming effort, save memory space and clean up your circuit layout. To do so, however, you need to know how LOGO! has named the blocks.
Programming LOGO! 3.3 From circuit diagram to LOGO! program Creating this circuit with LOGO! In LOGO! you create a circuit logic by interconnecting blocks and connectors: Note Although you have four inputs available for logic operations (Page 120), most of the views only show three inputs for reasons of clarity. You program this fourth input and assign parameters just like you do with the other three inputs. To create a new circuit logic in LOGO!, start at the circuit output.
Programming LOGO! 3.4 The four golden rules for operating LOGO! In our example we shall use only two inputs of the OR block and two inputs of the AND block; the third and fourth inputs are unused. Now connect the I/O to LOGO! . Wiring Connect the switches S1 to S3 to the screw terminals of your LOGO! : ● S1 to connector I1 of LOGO! ● S2 to connector I2 of LOGO! ● S3 to connector I3 of LOGO! The output of the AND block controls the relay at output Q1. The load E1 connects to output Q1.

Technical data A.
Determining the cycle time B The program cycle is the complete execution of the circuit program, that is, primarily the reading in of the inputs, the processing of the circuit program and the subsequent writing the outputs. The cycle time is the time required to execute a circuit program once in full. You can determine the time required for a program cycle using a short test program. Create this test program in LOGO! to return a value from which you can calculate the cycle time.
Determining the cycle time Explanation The inverted flag block changes its output signal at each program execution. Thus, one logic level (high or low) width is exactly equivalent to the length of one cycle. Hence, a period lasts two cycles. The threshold trigger indicates the ratio of periods per two seconds, which results in the ratio of cycles per second.
