Non-project Device: Enter the IP address and TSAP port to enable connection to the non-project device. Data transfer table See Tools -> Ethernet Connections (0BA7 and 0BA8 only) (Page 100) for more information about data transfer configurations.
Tutorial 3.5 Practical example Note • If you choose the LOGO! Base Module when creating connections, the terminal automatically uses the available connector in the left-to-right order. • If you choose a specific connector, the terminal uses the connector that you selected. 3.5 Practical example 3.5.1 Practical example: Introduction This practical sample application (Page 168) for a service water pump offers new users a step-by-step introduction.
Tutorial 3.5 Practical example Requirements of the control system ● Service water must be available at all times. An emergency control system must change over to drinking water supply, for example, if service water runs low. ● The ingress of service water into the drinking water network must be prevented when switching over to drinking water supply. ● The pump must be disabled if the service water reservoir runs low of water (dry-run protection).
Tutorial 3.5 Practical example 3.5.3 Layout of the solution The pump and a solenoid valve are controlled by a pressure switch and three float switches, which are installed in the service water reservoir. The pump must be switched on if the pressure in the reservoir drops below minimum. When the operating pressure is reached, the pump is switched off again after a tracking time of a few seconds. The tracking time prevents pump oscillation if water is tapped over an extended period.
Tutorial 3.5 Practical example 3.5.4 Solution with LOGO! Connecting field devices In addition to the LOGO! device, all you need is the pressure switch and the float switches to control the pump. If you are using a 3-phase AC motor, a contactor relay is required for switching the pump. In systems with single-phase AC pumps, you must install a contactor relay if the current of the AC pump exceeds the switching capacity of the output relay Q1.
Tutorial 3.5 Practical example Block diagram The block diagram shows you how to interconnect the pump controls and the solenoid valve. The layout corresponds with the structure of the circuit program.
Tutorial 3.5 Practical example 3.5.6 Placing blocks In the next step, place the required blocks into the programming interface. Note that in addition to the standard and special functions, you also require I/O blocks. At this stage of progress it is sufficient for you to place the blocks roughly into position that seems appropriate to you for connecting them later. You can carry out fine positioning after making all of the connections.
Tutorial 3.5 Practical example UDF Editor: 3.5.7 Connecting blocks Connect the blocks as you have planned previously. Connect them by drawing the connecting line, starting at the output of a source block and ending at the input of the target block. This has the advantage that you are shown the name of the connector when you interconnect the input, which is particularly advantageous for the various connectors of SFBs.
Tutorial 3.5 Practical example LAD Editor: UDF Editor 3.5.8 Cleaning up the programming interface Some of the connecting lines might be routed across blocks, which can make the layout of the circuit program hard to read. To "tidy up" the programming interface, select the connecting lines and blocks where required and move or align them until you have optimized the circuit program layout as far as possible.
Tutorial 3.
Tutorial 3.5 Practical example 3.5.9 Optimizing the view You can cut unwanted though unavoidable line crossings using the Cut/Join tool (Page 39) to improve the appearance.
Tutorial 3.5 Practical example UDF Editor Note that UDF blocks do not support inputs, outputs, analog inputs, analog outputs, M8, M25, M26, M27, shift registers, the data log or message text function blocks. You have now completed your circuit program. Verify all connections once again and configure the block parameters to suit your requirements. 3.5.10 Testing the circuit program Place your circuit program in simulation mode (Page 95) and verify that your program is error-free.
Tutorial 3.5 Practical example 3.5.11 Circuit program documentation Program comments You can now start to add comments to your program using the Text tool (Page 39). Describe the I/O to make your circuit program easy to understand. You do not have to display the connector names on-screen. You should nevertheless assign names to the connectors, because you may want to print out a connection list at a later time.
Tutorial 3.5 Practical example Transferring the circuit program Finally, transfer your circuit program to a suitable LOGO! version and then connect the module. Connect LOGO! with the consumer devices in your project. You have created the circuit program under LOGO!Soft Comfort within a very short time and, compared with conventional methods, you have saved yourself a considerable amount of time and effort. 3.5.
Sample applications 4 Introduction To give you an impression of the versatility of LOGO!, LOGO!Soft Comfort includes a small collection of applications, in addition to the service water pump application shown in the tutorial. This online help briefly describes the tasks and presents the relevant solutions with LOGO!Soft Comfort. You can find these circuit programs, as well as many others, on your LOGO!Soft Comfort DVD-ROM in the ..\Samples folder.
Sample applications 4.1 Air-conditioning system ● The fresh-air fan may only be switched on if the flow sensor signals the safe operational state of the extractor fan. ● A warning lamp indicates failure of one of the fans. Standard solution The fans are under monitoring by means of flow sensors. If the sensors registered no air flow after a short delay time has expired, the system is switched off and an error message is generated, which can be acknowledged by pressing the off button.
Sample applications 4.2 Factory door You can invert output Q3 to use output messages at Q4. Relay Q4 only drops out if main power is lost or if there is a fault in the system. The output can then be used for a remote message. 4.2 Factory door Requirements for a gate control system In many cases a factory entrance is closed with roll gates. Those gates are only opened when vehicles need to enter or leave the factory grounds. The gate is controlled by a gatekeeper.
Sample applications 4.3 Heating control 4.3 Heating control Requirements of the heating control This example illustrates a heating control where the flow temperature of the heating is to be controlled at an inverse proportion to the outdoor temperature. This means that the lower the outdoor temperature, the greater the flow temperature. PT100 sensors measure the outdoor and flow temperatures. With an outdoor temperature of 0 °C, the flow temperature should be 50 °C (x).
Sample applications 4.3 Heating control LOGO!Soft Comfort Solution ① ② ③ ④ ⑤ A PT100 sensor is connected to AI1 which measures the flow temperature. The parameters for the analog amplifier are as follows: • Sensor: PT100 • The PT100 sensors stipulate the measuring range and parameters. • Unit: Celsius • Resolution: x 1 The amplifier causes the actual temperature that the sensor has measured to be issued as the output. A PT100 sensor is connected to AI2 which measures the outdoor temperature.
Sample applications 4.3 Heating control ⑥ The parameters for the analog comparator are as follows: • Sensor: No sensor • Gain: 1 • Offset: 0 • On Threshold value: 4 • Off Threshold value: 0 The analog comparator switches on the output Q2 if the difference between the flow temperature and the standardized outdoor temperature exceeds 4 °C. ⑦ If the difference falls below 0 °C, the analog comparator switches the output Q2 off again. Output Q2 switches the heating on and off.
Sample applications 4.4 Fill station 4.4 Fill station Requirements for a fill station A box shall be filled with two different items, up to a specified total for each item. When all items are in the box, it will be transported to the packaging station. A conveyor belt transports the items of both types to the box. (This example does not show the filling conveyor belt.
Sample applications 4.
Sample applications 4.4 Fill station Parameters of the function blocks Note the following parameter usage: ● The on-thresholds of counters B001 and B002 define the maximum number of items of each item type to be put in the box. ● The pulse width (TH) of the edge-triggered wiping relay defines the duration of the movement of the conveyor belt.
Sample applications 4.4 Fill station Message texts Message text block B010 displays a message text whose four lines all tick "line by line", such that two screen forms display in alternation. The first shows bar graph representations of the counted items (B001 and B002 current values) and a bar graph for the summed total items as calculated by B007. The second screen form shows the same values numerically and with text descriptions.

Reference material 5.3 Special functions 1. LOGO! can read in electric voltages from 0 V to 10 V or electric currents from 0 mA to 20 mA to one analog input. The physical quantities (for example, temperature, pressure, speed etc.) must therefore be converted into one electric quantity. This conversion is performed by an external sensor. 2. LOGO! reads in the electric quantity and, with further processing, converts it into a standardized value within the range 0 to 1000.
Reference material 5.3 Special functions Gain The standardized value is multiplied with a parameter. Using this parameter you can boost the electric quantity; hence, this parameter is called the "gain". Zero point offset You can add or subtract a parameter to or from the boosted standardized value. Using this parameter you can move the zero point of the electric quantity; hence, this parameter is called the "zero point offset".

Controlling manipulates a quantity without being able to compensate for outside influences.
Reference material 5.3 Special functions Basic concepts of regulating In the example, the current for the electric heating is the manipulated variable. The changeable resistance is the actuator. The hand that operates the actuator is the control. The actual room temperature is the controlled variable or the process value. The desired room temperature is the command variable or the setpoint value. The electric heating is the control process. The thermometer is the sensor.
Reference material 5.3 Special functions Control loop The process value x influences the manipulated variable M by means of the regulating device. This creates a closed circuit that is also known as a control loop. If, in the example above, the window is opened, the temperature in the room drops. The person must increase the heat output of the heater. If the heat output increases too much, it gets too hot. The person must then reduce the heat output.
