What limits the number of virtual input and output instructions in a plc ladder logic program?11/19/2022 (ii) The motor shaft takes 1 s to rotate through 1.8°. This means that: (i) Each pulse input to the motor rotates the motor shaft by 1.8°. A stepper motor has a step angle of 1.8o. Ans c 10) Decide whether each of these statements is True (T) or False (F). The absolute angular position of the shaft. The change in angular position of the shaft. 0.2 Ω Ans d 9) An incremental shaft encoder gives an output which is a direct measure of: A. Ans b 8) The change in resistance of an electrical resistance strain gauge with a gauge factor of 2.0 and resistance 100 Ω when subject to a strain of 0.001 is: A. A controlled adjustable pressure applied to one side. Such a sensor will need to have a diaphragm with: A. (i) T (ii) T (i) T (ii) F (i) F (ii) T (i) F (ii) F Ans c 7) A diaphragm pressure sensor is required to give a measure of the gauge pressure present in a system. Which option BEST describes the two statements? A. (ii) Isolate the CPU from high voltages or currents. 240 V Ans aĦ) Decide whether each of these statements is True (T) or False (F).The reason for including optocouplers on input/output units is to: (i) Provide a fuse mechanism which breaks the circuit if high voltages or currents occur. (i) F (ii) F Ans a 5) Which of the following is most likely to be the voltage level used internally in a PLC, excluding the voltage levels that might occur during conditioning in output/input channels: A. (ii) Is isolated from the output load by an optocoupler. A triac output channel from a PLC: (i) Is used for only a.c. (i) F (ii) F Ans c 4) Decide whether each of these statements is True (T) or False (F). A relay output channel from a PLC: (i) Is used for only d.c. (i) F (ii) F Ans a 3) Decide whether each of these statements is True (T) or False (F). A transistor output channel from a PLC: (i) Is used for only d.c. Ans d 2) Decide whether each of these statements is True (T) or False (F). This is done to make sure that the user is aware of using a local simulation versus an actual PLC.Personal logic computer. TIA Portal will notify the user that other connections will be terminated. Select the PLC and Press on “Start Simulation”. Therefore, different software packages are used for each device. The PLC and HMI programs must be simulated separately. Step 4.10 - Change the “LED1” tag to “LED2” on the second circle Step 5 - Simulate the PLC in TIA Portal It’s possible to create an infinite number of animations in the case of analog tags. In this case, the tag can only take on “0” and “1” and thus we have only those two specified. The “Range” tab is used to identify the tag value to check against. First, we need to make sure that it’s tied to the HMI tag we’ve specified before and that it toggles the color of the Circle to indicate the state. The animation will have multiple options. Under the “Animations” tab, the user can create an animation by clicking the “Add new animation” button on the left-hand side. Step 4.8 - Add an “Appearance” animation to the Circle Siemens TIA Portal PLC Programming - Circle Element & Tag Background Transitions
