Operation on device LOGO! Soft Comfort V6.1 Application example Logic module LOGO! I IA AS FA PS4 © Siemens AG 2009 - Subject to modifications Analog – PI controller Introduction Wiring Integrated functions Operation on device LOGO! Soft Comfort V6.1 Application example 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. Logic module LOGO!

Soft Comfort V6.1 Application example 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. Logic module LOGO!

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).

I IA AS FA PS4 © Siemens AG 2009 - Subject to modifications Analog – Pulse Width Modulator (PWM) Introduction Wiring Integrated functions Operation on device LOGO! Soft Comfort V6.1 Application example 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. Logic module LOGO! I IA AS FA PS4 © Siemens AG 2009 - Subject to modifications Analog – Pulse Width Modulator (PWM) Introduction Calculation rule : Q = 1, for Ax / (Max - Min) of time period PT Q = 0, for PT - [Ax / (Max - Min)] of time period PT Wiring Note: Ax in this calculation refers to the actual value Ax as calculated using the Gain and Offset.

Soft Comfort V6.1 Value 2 Application example Value 3 Value 4 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 (-32768 - +32767). A result out of this range causes an overflow-error. Logic module LOGO!
