Here are some tips to solve Lab assignment Fust, let's look at the motor logie which is controlled by S 3 (selector switch) and other conditions Since the motor is wured in safety mode (running when MR oft) we have to use an intermediate bit to invertits loc X105_3XXIO(LS)xXIO(METAL DN)XXIO TOTAL DN)XIO(TIMERIOTTY-OTE(B3.00) X1OB3:00 OTECMR) Notice the inversion on the second ring. This could have been done in a ple rung but it is easier and toore understandable this way Remember that the FPS most activate an up counter called TOTAL (CS) preurt to 10, while IPS must activate as up.counter called METAL (C1) preset to 5 Also, IPS directly activates a 10 sec ter called TIMER10 The blue light must only work when the put is not removed from the IP Swathin the 10 second pened, that is when TIMER 10. done. Therefore XICTIMER10DN) 011(B30/1) XICL_)>OTUC3.DVD) XIC(B3.01) OTEL) Finally, the red light must ether be seady on during the 10 second pened or flash on and of 250ms the METAL count reaches 5 Therefore EXICCTIMERIOTT).XIO(METAL DN)(XIC(METAL DN)XICCTIMERISOA/TT)=OTEL_1) Remember to setup the flashingtimers (TIMER250A and TIMER2503) as well as to reset (RES) the counters (TOTAL and METAL) with S 1 and 2 and control the green light (L ) with the motor
An END rung automatically appears as the only rung in the LAD 2 ladder logic window Add a new rung by selecting the appropriate icon from the 'User' instructions toolbar or by right-clicking on the END rung ID (0000) and selecting 'Insert Rung Instructions (XIC, XIO, OTE, OTL, and OTU) can be inserted within the rung by selecting the appropriate icon from the 'User' or 'Bit' instructions toolbar or by right-clicking on the rung and selecting 'Insert' and choosing the instruction from the list. The instruction address is entered by typing it in place of the question mark (?) that appears on top of the instruction (i.e. 1:0/1 for terminal 1 of the input module). Enter a Description for the device the instruction is addressed to (i.e. input devices: NO LS, NO MC PB, NO SS, NO PS. Output devices: Motor Relay, Red PL, Green PL, Blue PL.) Enter a Symbol for the device the instruction is addressed to (i.c. input devices: L_S, S1, S2, S_3, S_4, CP_S, FP_S, IP_S. Output devices: M_R, L1, L2, L_3) Using symbols will allow to refer to the device later by its symbol rather than by its address.

The program is required to operate as follows: Note: The conveyor will be operated and programmed in Safety Mode (switch the conveyor output to the NC position) so that the Motor will stop when it receives a signal. When the switch S_3 is activated, the conveyer is required to run (M_ROFF). When the conveyor is running the green light L_2 is to be energized The fiber optic sensor FP_S must count the TOTAL parts that go through the conveyor. The inductive sensor IP_S must count the METAL parts that go through the conveyor. Each time a metallic part is detected by IP_S the conveyor must temporarily stop for 10 seconds or until the part is manually removed. The red light L_1 must be energized during this period. If the part is not removed within the 10-second period the blue light L_3 must be latched The limit switch L_S must momentarily stop the conveyor and unlatch the blue light L_3 The conveyor must be stopped when the METAL part count reaches 5 or when the TOTAL part count reaches 10. If the METAL part count reaches 5, the red light L_1 must flash in intervals of 250 ms. Pushbutton S 1 is used to RESET the TOTAL part counter Pushbutton S_2 is used to RESET the METAL part counter
