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.

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: Ta Trg Q T (OFF delay) 1s 15s 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.

Timer – Multiple function switch
Switch with two different functions: Pulse switch with off delay Switch (continuous lighting) Symbol for this function is Integrated functions Q Trg 5s >20s Diagram: 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.

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 S1 Dir 6 6 5 5 5 S2 4 4 4 3 3 3 3 2 2 2 - + 1 1 C1 Counter R >=5 Q H1 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.

Counter – Hours counter
1 2 3 4 MN = MI MN = 0 Q Ral En R OT 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.

Symbol for this function is Diagram: Fre Q gate time Fre > On Fre > Off Fre < Off Fre < On Fre =12 Fre = 5 Fre = 3 On = 10 Off = 4 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.

Integrated functions Diagram: Timing diagram A: Function with negative differential delta value Timing diagram B: Function with positive differential delta value

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

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

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

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

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). Integrated functions

Analog – Pulse Width Modulator (PWM)
Integrated functions Description of the function: The PWM function modulates the analog input value Ax into a pulsed digital output signal. The pulse width is proportional to the analog value Ax. The function reads the value of the signal at the analog input Ax. This value is multiplied by the value of parameter A (gain). Parameter B (offset) is added to the product, as follows: (Ax * Gain) + Offset = Actual value Ax The function block calculates the proportion of the value Ax to the range. The block sets the digital output Q high for the same proportion of the PT (periodic time) parameter, and sets Q low for the remainder of the time period.

Analog – Pulse Width Modulator (PWM)
Calculation rule : Q = 1, for Ax / (Max - Min) of time period PT Q = 0, for PT - [Ax / (Max - Min)] of time period PT Note: Ax in this calculation refers to the actual value Ax as calculated using the Gain and Offset. Min and Max refer to the minimum and maximum values specifed for the range. Integrated functions Example 1: Periodic time (PT) = 4 sec. Ax = 500 1) 500 / (1000-0) = 0,5 2) 4 sec. * 0,5 = 2 sec. Q = 2 sec. high , 2 sec. low Example 2: Periodic time (PT) = 10 sec. Ax = 300 1) 300 / (1000-0) = 0,3 2) 10 sec. * 0,3 = 3 sec. Q = 3 sec. high , 7 sec. low

Analog - Analog Math Description of the function:
The function combines four values and three operators to form an equation. The operator can be any one of the four standard operators: + , - , x , / For each operator, you must set a unique priority of High ("H"), Medium ("M"), or Low ("L"). The high operation will be performed first, followed by the medium operation and the low operation. The operand values can reference another previously-defined function to provide the value. You can also configure the behavior of the function when the Enable parameter "En"=0. The function block can either retain its last value or be set to 0. The result is an internal analog value ( ). A result out of this range causes an overflow-error. Operator / Priority Value 1 Value 2 Value 3 Value 4 Integrated functions

You can program the function to set the output on a zero division error, an overflow error, or when either type of error occurs. If you select the “Automatically reset” checkbox, the output is reset prior to the next execution of the function block.
