Inside AutomationView: Implementing GEMMA for Master State Coordination in PLC Sequences

Key Takeaways: The GEMMA framework provides a standardized visual approach to managing machine states beyond normal production (stops, faults, preparations). Integrating GEMMA directly into your AutomationView GEMMA implementation bridges the gap between high-level operational modes and low-level Sequential Function Charts (SFC). By decoupling the master state logic from the physical actuators, engineers achieve significantly more […]

Inside Conveyor Belt Motor Power Calculation: Sizing for Industry

Key Takeaways: Motor sizing relies on accurate calculation of effective tension ($T_e$). Static friction demands significantly higher starting torque than dynamic operation. System mechanical efficiency ($eta$) directly dictates the final required kW or HP. Sizing a motor for a heavy-duty bulk material conveyor is rarely as simple as multiplying weight by speed. In industrial material […]
