Automation System Upgrade for concrete mixing machine
Project Overview: CSI AUTOMATION re-engineered the control system for a Dragline Concrete Batching Plant (Centrale à rayons raclant). Challenge: The existing hardware (Siemens S7-200 PLC and ESA HMI) was obsolete and prone to failure. Solution: We migrated the system to a Schneider Modicon M221 PLC paired with a Magelis HMI. Weighing System Upgrade: The weighing system was completely overhauled using LAUMAS S-type load cells connected to W100 digital weight indicators. Communication Architecture: PLC ↔ Weight Indicators: Modbus RS485. PLC ↔ HMI: Modbus TCP/IP.
