5-level elevator (50 ON/OFF Inputs/Outputs, CANopen control) – Training bench (ref: ESD350000)
Designed for the study of the sequential automatic process control with safety control by:
▪ interpreter, Grafcet simulator on PC (steps, conditional actions, macro-steps, divergence, convergence…).
▪ PLC through 4-mm Inputs/Outputs sockets.
▪ PLC or any other control device, through CANopen cell.
It enables the control of large ability elevator models:
▪ Up motion priority.
▪ Down motion priority.
▪ Car pre-positioning for the waiting time schedule (morning, noon, evening).
▪ Control of several elevator columns.
Specifications:
27 Outputs (PLC inputs):
▪ (1) 5 level calls (car buttons).
▪ (2) 5 level presence detections.
▪ (3) 5 opening/closing door detections .
▪ (4) 4 car calls for up motion (level 0 to 3) .
▪ (5) 4 car calls for down motion (level 4 to 1).
▪ (6) 2 over-limit detections (up & down).
▪ (7) 1 emergency stop (car button).
▪ (8) 1 car overweight (normal) detections .
23 Inputs (PLC outputs):
▪ 5 lights for car call recording (passenger inside the car) (1).
▪ 4 lights for up motion (level 0 to 3) (4).
▪ 4 lights for down motion (level 4 to 1) (5).
▪ 1 light for emergency stop recording (7).
▪ 5 opening/closing door detections (3).
▪ 1 car up motion control (4).
▪ 1 car down motion control (5).
▪ 1 opening door control (3).
▪ 1 audio alarm control {(6), (8)}.
Grafcet editor provided in basic version, characteristics :
► Editor: enables to draw the Grafcet with the basic tools: step, transition, AND/OR divergence/convergence, macro steps…
► Generator: converts the Grafcet into executable code, checking the syntax & coherence between target & used variables…
► Simulator: executes the Grafcet in simulation, one “click” on the input variable enables the activation of the corresponding transition, the whole graph can be tested before controlling the operating part.
► Interpreter: enables the execution & control following the step-by-step, path or quick mode.
Some characteristics: 256 steps, 256 transitions, 256 * 8-bit memories, macro steps, possibility of several independent Grafcets operating simultaneously.
