To communicate with the 55-90U, you must use the STEP 5 programming language. This programming language specifies words (statements), their correcl form, and their syntax. You use these words to write a statement list (sTL). This statement list is your program. The S5-90U carries outthe instructions ofthe statement list. lf you have a programmerwith a displayscreen or an IBM or IBMcompatible personal computer, you can also use a ladder diagram to communicate with the 55-90U. A ladder diagram and a statement list are two

representationformsforprograms. Thischaptertellsyouhowtoconvertacircuit diagram to a statement list and explains the format and components of a statement. This chapter also explains linear programming and provides programming examples for the operations with which the 55-90U works.

Converting a Circuit Diagram to a Statement List (STL)

Suppose you were asked to devise a plan to turn on a signal lamp. lf you did not have a programmable controller, you would have to make a circuit diagram as shown in Figure 3-1.

When a normally open contact (s1) is activated and a normally closed contact (S2) is not activated, a srqnal lamp (H1) goes on. rhe-load culrent (signal lamp) flows over contacts s1 and 52.

The diagram shows the connection of sensors 51

and 52 to terminals for digital inputs and the connection of the signal lamp to a terminal for digital output. The 55-90U detects whether voltage is present at its inputs (indicated by signal state "1") orwhethervoltage is absent(indicated by signal state "0"). However, the S5-9OU cannot determine whether an input is assigned to a normally open contact or to a normally closed contact. You must indicate this assignment in your program. You must also indicate the conditions underwhich the lamp at output Q 32.5 is switched on. FiEure 3-2. Terminal Conn€dion Diagram (piogrammable Control)

3.2

Your program consists of statements directed to the S5-90U. you must create a statement Iist (sTL). lf you have a programmer with a display screen or an IBM or IBM-compatible personal computer, you can also enter the statements as a ladder diagram (LAD, see Figure 3-3). ln the example in Figure 3-3, signal lamp H1 is supposed to light up when a normally open contact (51) is activated and a normally closed contact (S2) is not activated. ln this case, both inputs I 32.0 and I 32.1 carry voltage. Both carry signal state "1." For this example, you must combine the two inputs through logic AND in your program. ln your statement list, you indicate this with the letter "A" (AND operation). lf you are usin g a ladder d iagrarnlyou indicate the AND operation with the series connection of the symbols j E- (these symbols indicate scanning for signal state "1").

Creating a Linear Program

The 55-90U processes OB1 cyclically. The controller processes each statement. When it reaches the block end statement (BE), it returns to the first statement and continues processing- This is called cyclical programming (see Figure 3-5).

Block Types

The S5-90U works with the {ollowing block types:

relativeaddressofthestatementautomaticallyThisaddressisinsignificant for the format of the statement. Appendix D lists all operations and operands.

For processing simple automation tasks, you can program individual operations in one block. Forthe 55-90U, this is organization block 1 (OB1).

. r

Organization blocks (OBs) - OBs manage the control program. Theyform the interface between the operating system and the control program. Program blocks (PBs) - PBs arrange the control program according to functional or technical aspects. Function blocks (FBs) - FBs are special blocks for programming frequently recurring or especially complex program parts (e'g., arithmetic functions)They have an extended set of operations (e.g., Jump operations within a block, see Appendix D). Data blocks (DBs) - DBs store data needed to process a control program' Actual values, limiting values, and text are examples of data.

You can carry out many operations with the S5-90U. This section discusses the following operations and provides an example for each one:

You enter OB'l on your programmer or personal computer. To do this, you must call up OBl (see the manual for your programmer or personal com puter). One statement normally takes up two bytes in the program memory. Some operations require two-word statements (e.g., the operation "load a constant"). You must count these operations twice when figuring the Iength of your program. You must end OB1 with the BE statement. After you enter OB1 on your programmer or personal computer, transfer it to the S5-90U (see the ma nual for your prog rammer or persona I co mputer).

You can use a simulator to test all the examples in this section (see subsection 1.3.2). Subsections 3.5.1 and 3.5.2 provide practical examPles 5ubsections 3.5.3 through 3.5.8 provide theoretical examples.

The system consists of a hopper, a counting arm, a motorized conveyor belt, a light barrier, a buzzer, and an 55-90U. The counting arm is wired to input I 33. on the S5-90U. The motor is wired to output Q 32. 1 via a contactor. The buzzer wired to output Q 32.4. 1

following example illustrates interrupt processing with counter and off_delay

timer operations.

The shipping department of a spare parts factory has an automated system packing 100 stainless steel cogwheels to a box (see Figure 3_6).

is

When the packing supervisorturns on the motor (input I 32.2), the outlet at the bottom of the hopper is released (output Q 32.0) and the cogwheels drop one by one onto the belt. lt takes 30 seconds for one part to reach a packing box at the end of the belt.

for

Each time a part passes through the hopper outlet, the counting arm sends a counting pulse to counter input I 33.1. The counter counts up by one. The supervisor has programmed DB1 to activate counter input I 33.1 and has programmed OB3 to reset output Q 32.0 (see Figure 3-7 and section 4.4). When the count reaches '100, the S5-90U resets output Q 32.0, closing the hopper outlet im medi ately. The 55-90U also sta rts a n off-d elay ti mer that resets output Q 32.1 after 30 seconds, shutting off the motor. By this time, all the parts have reached the packing box.

When another packing box is ready to be filled, the supervisor can restart the motor. The supervisor can use the "OFF" switch to stop the packing procedure at

.

A light barrier at the end of the conveyor belt ensures that a packing box is in place to receive the cogwheels while the belt is running. The light barrier is wired to input I 33.0. lf the packing box is pushed out of position while the belt is running, the light barrier triggers an interrupt. The S5-90U calls OB3 automatically. The packing supervisor has programmed DB1 to activate interrupt input I 33.0 and has programmed OB3 to shut off the motor immediately and sound a buzzer (see Figure 3-7 and section 4.3). When the buzzer sounds, he can then put the box back in place before any of the cogwheels hit the floor. Fig ure 3-8 shows the STL prog ram for the above exa m ple. 0| lzt

ln the automated packing system described in subsection 3.5.1, it takes 30 seconds for each part to reach a packing box at the end of the belt. When the packing supervisor turns on the motor (input I 32.2), the motor requires 5 seconds to reach its normal speed. So the supervisor has included an on-delay timer (T2) in his program forthe S5-90U. When he turns on the motor, the on-delay timer is triggered. After 5 seconds, the timer runs out and releases the hopper outlet (output Q 32.0). By the time the first stainless steel cogwheel drops from the hopper to the belt, the belt has reached its normal speed. Figure 3-9 shows the

Edge Evaluation

"l " indicates thatvoltage is present and signal state "0" indicates that voltage is absent. The term "edge" indicates the transition from one signal state to another signal state. A leading edge (also called a positive edge) indicates the transition from signal state "0" to signal state "1." A trailing edge (also called a negative edge) indicates the transition from signal state "1 " to signal state "0" (see Figure 3-13)

The S5-90U can detect a leading edge and evaluate it for specific purposes.

You can write your program to react to changes in signal state. The program can check the program memory during each cycle to see if a particular signal state has changed sincethe last cycle (e.9., the program can checkthe signal state of input I 32. 1, see Table 3- 1 ). The program must compare a signal state f rom one cycle to a signal state in the next cycle. The program stores the signal state from the previous cycle in a flag. During the next cycle, the program compares the current signal tothesignalfromthepreviouscycle(thesignal thatisstoredintheflag). lf th e signal state changes from "0" to " 1, "the S5-90U detects the cha nge and ca n reactto it.

3.5.8 CounterOperations The S5-90U uses counter operations (software counters) to handle counting jobs directly. ln Figure 3-18, counter 1 is setto the count 7 when the signal state at input l 32. l changes f rom " O" lo " l." Output Q 32.2 now carries signal state " l." Every time input I 32.0 is switched on, the count is decremented by 1 (count down). The output is set to "0" when the count is "0."

Programmable Functions

The 55-90U has the following functions that you can program according to your needs:

. .

lnterrupt input (see section 4.3) Counter input (see section 4.4)

4.1

Default Settings in DB1

To make programming easierfor you, data block 1 (DB1) is integrated into the S5-90U with preset values (default parameters). After performing an overall reset, you can load this default DB1 from the 55-90U into your programmer or personal computer and display it on the screen (see Figure 4-1).

Make surethat the character string "DB1 " is in front of the first parameter block, followed by at least one filler (such as a blank space or a comma). Make su re that each para meter block beg ins with a block lD followed by a colon and at least one filler (such as a blank space or a comma). Put a filler (such as a blank space or a comma) after each parameter and each value that you enter (see Figure 4-1). Make sure there is a semicolon (;) at the end of each parameter block followed by a f iller (such as a blank space or a comma). lf a parameter block is enclosed between comment characters (#), it will not be interpreted by the PLC. lfthe parameter block is to be interpreted by the PLC, overwrite the comment characters in front of the block identifier and at the end ofthe relevant parameter block (i) with a space.

lnterrupt-driven processing occurs when a signal from the Process causes the S5-90U to interruptcyclicscanning and process a specificprogram. Forthe 55-90U, a signal state change from "0" to " 1 " (positive edge) at input I 33'0 triggers an interrupt. The is-gOU then interrupts cyclic scanning in OB1 and jrmps to OB3. When the controller f inishes processi ng OB3, it iumps back to the point of interruption in OB1 and resumes processing. To use input I 33-0 for interruPt-controlled program processing, proceed

as

Wire interruptinputl 33.0(seesection 1.3.1). Program an interrupt reaction in OB3. Activate the interrupt input in default DB1 asfollows: a.

After you have written your program, you must transfer it to the 55-90U so that you ca n test the program. you can load your program into the S5-9OU f rom your programmer or personal computer, or from a memory submodule. You ca n test you r prog ram by displayi ng the signal status a nd RLO of va rious operands. After you have tested the program Jnd made any necessary corrections, you may wantto back up your program on a memory submodule. lf you have backed up your program on this memory submodule, your program will be saved even ifthe powerfails while there is no battery in your 55_90U.
