Description

The function block FB_EcoModus automatically switches to an energy-saving Eco mode after a defined idle time and automatically returns to full load operation when operation is required again.

Ideal for training, further education and plant planning!

Note: All modules are designed exclusively as a learning and optimization basis and are not approved for live operation. System modules, in particular, must be finally tested and commissioned by qualified personnel before productive use.

How it works
Timer start

As soon as there is no BetriebAnforderung and the block is active, a TON timer ( LeerlaufTimer ) starts.

Activate Eco mode

If the timer reaches the set LeerlaufLimit time, the following happens:

  • The Sollfrequenz is set to FrequenzEco
  • ImEcoModus is set to TRUE
  • The StatusText shows “Eco mode active”
Return to full load

If an BetriebAnforderung is detected again during this time:

  • The timer is stopped
  • The target frequency jumps back to FrequenzMax
  • ImEcoModus is deactivated
  • The StatusText shows “Full operation active”
Idle test running

As long as the timer is running but is still below the idle limit, the system remains in transition with FrequenzMax and the status "Idle check in progress".

Module deactivated

If the block is not active, the control is completely deactivated, FrequenzSoll is set to 0 and the timer is reset.

Technical details
  • Inputs: BetriebAnforderung (BOOL), Aktiv (BOOL), LeerlaufLimit (TIME), FrequenzMax , FrequenzEco (REAL)
  • Logic: TON timer with IN = NOT BetriebAnforderung AND Aktiv , PT = LeerlaufLimit ; nested IF/ELSIF for mode change and frequency/status output
  • Outputs: FrequenzSoll (REAL), ImEcoModus (BOOL), StatusText (STRING)
Possible applications
  • Automatic power reduction in drive or engine systems
  • Energy savings during idle operation in pumping or conveying systems
  • Retrofit solution for consumption optimization in existing systems
compatibility
  • Runs on Siemens S7-1200 and S7-1500 controllers
  • Compatible with TIA Portal from version V13
  • Recommended: TIA Portal V16 or higher for HMI visualization and PLCSIM
