Sensors may be: • pushbuttons, switches, photoelectric barriers, etc. • temperature, pressure or ultrasound sensors (Beros) etc., with 0...10V outputs directly at the 4 analog inputs of the 12 and 24 V DC basic devices or the analog module AM2 • or the appropriate device with current output 0...20mA/4...20mA to the inputs of the analog module AM2 • or connect up to 2 resistance thermometer PT100 to AM2 PT100 in 2 or 3 wire connection technology Wiring LOGO! 230 ... LOGO! 12/24 ... 2-wire technology 3-wire technology With 2-wire connections no correction of the impedance of the measurement line occurs. 3-wire connection suppresses this influence. The inputs of these devices are grouped into 2 blocks of 4 I each. Different phases are only possible between, not within the blocks. The inputs of these devices are non–isolated and therefore require the same reference potential (ground) as the power supply.

  24. S1 K1 K1 M Diagram: Trg Q T T Ta (Timer active) Timer – On-delay A look at the circuit diagram shows that the motor only starts after expiry of the delay time. This function is called On-delay. In words the motor will be switch on with a programmed ON delay time. Symbol for this function is . Integrated functions Description of the function: • With 0 to 1 transition of input Trg the timer starts. If the status of input Trg is 1 for long enough, the output is set to 1 on expiration of the time T. The output follows the input with on delay. The output is reset to 0 when the status at input Trg is 0. • If the status of input Trg changes to 0 before the time T has expired, the time is reset. The time elapsed is reset after a power failure.

  25. S1 K1 K1 M Diagram: Trg Ta R T T Q (Timer active) Timer – Off-delay A look at the circuit diagram shows that the motor only stops after expiry of the delay time. • This function is called Off-delay. • In words the motor will be switch off with a programmed OFF delay time. • Symbol for this function is . Integrated functions Description of the function: • When the input Trg is 1, the output Q is switched instantaneously to 1. When the status of Trg changes from 1 to 0, the timer will be activated. The output remains set. When the timer reaches the configured value (Ta=T), output Q is reset to 0. When input Trg is switched on and off again, the time Ta restarts. Input R (Reset) is used to reset the time Ta and the output before Ta has expired.

  26. K2 S1 K1 M K1 K2 Diagram: Trg Q TH TL Timer – On-/Off-delay A look at the circuit diagram shows that: • when S1 is closed, contact K1 closes with a delay time and the motor runs. • when S1 is opened, contact K2 opens with a delay time and the motor stops. This function is called On-/Off-delay. In words the motor is switched on and off with a programmed delay time. Symbol for this function is . Integrated functions Description of the function: The time TH starts after a 0 to 1 transition at input Trg. If the status at input Trg is 1 for the duration of the time TH, the output is set to 1 on expiration of the time TH. • (the output follows the input on delayed). When the status at input returns to 0, TL starts. If the status at input Trg is 0 for the duration of time TL, the output is set to 0 on expiration of the time TL.

  27. K2 K1 S1 K1 S2 K1 K2 M Diagram: Trg R T Q Ta Timer – Retentive On-delay A look at the circuit diagram shows that the motor M starts delayed after pressing the pushbutton S1. Pushbutton S2 (n.c. contact) stops the motor again. This function is called retentive On-delay. Symbol for this connection is . Integrated functions Description of the function: • The current time Ta starts with a 0 to 1 transition at input Trg. Output Q is set to 1 when Ta reaches the time T. The output Q is only reset to 0 when the status at input R is 1. Further switching actions at input Trg have no influence on output Q.

  28. T1 S1 Diagram: Trg Ta H1 T1 Q Timer – Wiping relay (pulse output) A look at the circuit diagram shows that the light H1 is only on, when the switch S1 is closed, but only as long as the set time at timer T1. Symbol for this connection is . Integrated functions Description of the function: When the input Trg is set to 1, the output Q is immediately switched to 1. The current time Ta starts in LOGO! at the same time and the output remains set. When Ta reaches the value specified in T (Ta=T), the status of output Q is reset to 0 (pulse output). On input Trg transition from 1 to 0 before the specified time has expired, the output follows immediately with a 1 to 0 transition.

  29. T1 S1 T1 H1 T1 Diagram: Trg T T Ta Q Timer – Edge triggered wiping relay A look at the circuit diagram shows that the light H1 remains on for the time specified on the timer T1 when the switch S1 is closed. Symbol for this connection is . Integrated functions Description of the function: • The output status is switched to 1 after the input Trg is set to 1. Time Ta is started at the same time. After Ta has reached the value specified in T (Ta=T) the output Q status is reset to 0 (pulse output). If input Trg changes again from 0 to 1 (retriggering) before the specified time has expired, the time Ta is reset and the • output remains switched on.

Wed Fri On Off Mon Tue Thurs Sa So Integrated functions : 16 05 Cam 1 07 30 : Cam 2 08 00 12 00 : Cam 3 10 00 12 30 Description of the function: • Every weekly timer has three cams. You can configure a time hysteresis for each cam. Within the cam setting you specify the on/off times. • If you enable “pulse output”, the timer will be reset after one cycle. “Pulse output” applies to all three cams.

  32. En Inv Q pulse period /pause width Timer – Asynchronous pulse generator • The pulse profile of the output can be customized via pulse/ pause ratio. Symbol for this function is . Diagram: Integrated functions Description of the function: • In the parameters you can adjust the pulse period and the pause width. With input INV you can also invert the output. You can customized the time period in seconds, minutes or hours. The time basis of both parameters can be set independently. The input block INV only negates the output if it is enabled via EN.

  33. En Q Q max. ON delay /max. OFF delay Timer – Random generator • With a random generator the output is switched on and off again within a specified time. Symbol for this function is . Diagram: Integrated functions Description of the function: • With a 0 to 1 transition of the input En a random time e.g. between 0 and 10 seconds is started. The output is set to 1 on expiration of the on delay time, if the input En is 1 at least for the duration of the on delay time. The time is reset if the status at input En returns to 0 before the on delay time has expired. When the input En changes from 1 to 0, a random off delay time between 0 and e.g. 15 seconds is started. The time is reset if the status at input En returns to 1 before the on delay time has expired.

  34. Trg Ta T (OFF delay) 1s Q 15s Timer – Stairway lighting switch • The input pulse (edge control) starts a specified time. The output is reset on expiration of this time. Prior to the expiration of this time (e.g. 15 s) an off pre–warning is generated. Symbol for this function is . Diagram: Integrated functions Description of the function: • With a 0 to 1 transition at input Trg, the current time starts and the output Q is set to 1. E.g. 15 s before Ta reaches the time T, the output Q is reset to 0 for a time of 1 s (configurable time). When Ta reaches the time T, the output Q is reset to 0. When input Trg is switched on and off again before Ta expires, Ta is reset (retriggering option).

  35. Diagram: Trg Q 5s >20s Timer – Multiple function switch • Switch with two different functions: • Pulse switch with off delay • Switch (continuous lighting) Symbol for this function is . Integrated functions Description of the function: • The output Q is set to 1 with a 0 to 1 transition of the status at input Trg. When the input Trg changes to 0 before expiration of the continuous lighting time, the output resets to 0 with an off delay of e.g. 5 seconds. With a 0 to 1 transition of the status at input Trg and if the status ’1’ is set at least for the duration of e.g. 20 seconds, the continuous lighting function is enabled and the output Q is • switched on continuously. If the input Trg is switched once again from 0 to 1 and again to 0, the output Q is switched off.

  36. S1 H1 Counter – Up and Down counter A look at the circuit diagram shows that the switch S1 triggers the counter pulses. Switch S2 determines whether the counter increases or decreases. When the counter status reaches a value >= 5, the light switches on. Diagram: Integrated functions Cnt Dir 6 6 S2 5 5 5 4 4 4 3 3 3 3 - + 2 2 2 C1 1 1 Counter 0 R >=5 Q Description of the function: • With every positive edge at input Cnt the internal counter increments (Dir = 0) or decrements (Dir = 1) by one count. Output Q is set to 1 when the internal value is greater than or equal to the value specified in Par. You can use reset input R to reset the output and the internal count value to the start value. When R=1, the output is 0 and the pulses at input Cnt are not counted. • If you set a “Start Value” the counter begins to count either up or down from this value.

  37. R En Ral Q MN = MI 3 3 2 2 1 1 MN = 0 0 0 4 3 2 1 OT Counter – Hours counter Integrated functions Description of the function: • The hours counter monitors the input En. As long as the status of this input is 1, LOGO! determines the expired time OT and the time–to–go MN. LOGO! displays the times in parameter assignment mode. Output Q is set to 1 when the time–to–go MN = 0. Use input R to reset output Q and time–to–go counter to the specified value MI. The internal counter OT continues the count. Use input Ral to reset output Q and the time–to–go counter MN to the specified value MI. The internal counter OT is reset to 0.

  38. Fre > On Fre > Off Fre < Off Fre < On Q Fre =12 Fre = 5 Fre = 3 Fre = 5 Fre gate time On = 10 Off = 4 Counter – Threshold trigger • The output is switched on and off, depending on two specified frequencies. Symbol for this function is . Diagram: Integrated functions Description of the function: • The threshold trigger measures the signals at input Fre. The pulses are captured across a specified period (gate time). • Output Q is switched on, if the value measured within the gate time is higher than the ON threshold. Q is switched off again when the threshold drops below OFF. On : is the ON threshold. It may be between 0000 and 9999. Off : is the OFF threshold. It may be between 0000 and 9999. Gate time: is the time interval during which the pulses at Fre are measured. It may be 00.05s and 99.99s.

  39. Analog – Analog threshold trigger Diagram: Description of the function: The output is switched on when the analog value exceeds a specified on threshold. The output is switched off when the analog value drops below a specified off threshold (hysteresis). • This function reads the analog value AI1 to AI8 as a value between 0 and 1000. The offset parameter is then added to the analog value. The result is multiplied by the gain parameter. Output Q is set to 1 if this value exceeds the on threshold (On). Q is reset to 0 again after the value drops below the off threshold (Off). Integrated functions

  40. Analog – Analog comparator Description of the function: • The function calculates the difference between the analog values Ax-Ay. The offset parameter is added to the difference. • Then the difference is multiplied by the gain parameter. • If this differential value exceeds the parameterized threshold, output Q is set to 1. Q is reset to 0, when the threshold drops below again. Integrated functions Diagram:

  41. Timing diagram A: Function with negative differential delta value Timing diagram B: Function with positive differential delta value Analog – Analog differential trigger Description of the function: The function reads the analog value of the signal at analog input Ax. This value is multiplied by the gain parameter. The offset parameter is added to the analog value. Output Q is set or reset depending on the specified threshold (On) and the differential value ( ). Integrated functions Diagram:

  42. Analog – Analog watchdog Description of the function: If the status at input En changes from 0 to 1, then the analog value of the signal at analog input Ax will be saved. This saved value is called “Aen”. The updated values Ax and Aen are each multiplied by the gain parameter. Then the offset parameter is added to the analog value. Output Q is set, if the input En is 1 and the updated value at the input Ax is outside of the range of Aen +/- . Threshold 1 defines the difference value above Aen, Threshold 2 defines the difference value below Aen. Integrated functions Diagram: 1 2

  43. Analog – Analog amplifier Description of the function: • The function reads the analog value of the signal at analog input Ax. This value is multiplied by the gain parameter. Then the offset parameter is added to the analog value, i.e. (Ax * gain) + offset = updated value Ax. Output AQ shows the updated value Ax. Integrated functions

  44. Analog – PI controller Description of the function: • If the input A/M is set to 0, then the special function sets output AQ with the value that is set with parameter Mq. If the input A/M is set to 1, then automatic mode commences. As an integral sum the value Mq is adopted, the controller function begins the calculations of the formulas. • The updated value PV is used within the formulas. Updated value PV = (PV * gain) + offset • If the updated value PV = SP, then the function does not change the value of AQ. With a disturbance, AQ continues to increase / decrease until the updated value PV again corresponds to SP. The speed with which AQ changes depends on the parameters KC and TI. If the input PV exceeds the parameter Max, then the updated value PV is set to the value of Max. If the PV falls short of the parameter Min, then the updated value PV is set to the value of Min. If the input R is set to 1, then the AQ output is reset. As long as R is set, the input A/M is disabled. The sampling time is fixed at 500 ms. Integrated functions

  45. Analog – PI controller Parameter: • Sensor: Type of sensor used • Min: Minimum value for PV • Max: Maximum value for PV • Gain: Gain for PV • Offset: Zero offset for PV • SP: Set point assignment • Mq: Value of AQ in manual mode Parameter sets: applied presets for KC, TI and Dir • KC: Gain • TI: Integral time • Dir: Action direction of the controller Number of decimal places in message text Integrated functions

  46. Analog – PI controller Parameter sets: To simplify the use of the PI controller, parameters for KC, TI and Dir are preset as sets for the following applications: Integrated functions Parameters can manually be specified via the parameter set “User defined”.

  47. Analog – Ramp Description of the function: • At the analog output, this special function starts up one of two levels or offset. Here you can set how quickly the level should be reached. If the input En is set, then the function issues the value StSp + offset at output AQ for the first 100 ms. • Then, depending on the connection of Sel, the function runs from value StSp + offset to either level 1 or level 2 at the acceleration set in Rate. • If the input St is set, the function runs to the value StSp + offset at the acceleration set in Rate. Then the function issues the value StSp + offset at output AQ for 100 ms. Finally offset is issued at output AQ. • If the input St is set, the function can only be restarted once the inputs St and En have been reset. • If input Sel has been changed, depending on the connection of Sel, the function runs from level 1 to level 2 or the other way round. If the input En is reset, the function immediately issues offset at output AQ. The analog value at the output is recalculated every 100 ms. Integrated functions

  48. Analog - Ramp Parameter: • Gain: Gain for AQ in message text • Offset: Zero offset for AQ in message text • L1 and L2: Levels to be reached • Largest output value: Maximum value that must not be exceeded under any circumstances • Start/ stop offset: value that is issued for 100ms in addition to parameter offset after starting the function and before reaching the offset value (prompted by input St). This parameter is intended for controlling motors. • Speed of change: Acceleration with which level 1, level 2 or offset is reached. • Steps/ second are input. • Number of decimal places in message text Integrated functions

  49. Analog - Ramp Diagram: Integrated functions

  50. Analog – Analog MUX Description of the function: • This special function outputs one of four predefined analog values or 0 at the analog output. If input En is set, then the function issues one of 4 possible analog values V1 to V4 at output AQ, depending on the value of S1 and S2. If the input En is not set, then the function issues the analog value 0 at output AQ. All 4 analog values V1 to V4 can be parameterized as a reference to another analog function, so the analog values can be dynamically changed in runtime (e.g. via potentiometer at an analog input).
