Modbus Communication Between Siemens S7-1200/S7-1500 and LOGO
This project focused on implementing seamless data exchange between Siemens S7-1200 or S7-1500 controllers and Siemens LOGO over Modbus, for synchronized control in multi-level automation environments.
Technologies used:
- S7-1200/S7-1500 PLCs configured as Modbus masters
- LOGO 8 as Modbus slave
- TIA Portal for structured data handling and HMI interfacing
Benefits Delivered:
- Cross-Platform Integration: Enabled smooth interaction between compact LOGO units and advanced S7 systems
- Centralized Control: Allowed higher-level PLC to monitor, override, and command LOGO process variables
- Cost Efficiency: Reduced overall hardware cost by utilizing LOGO! where high-end control wasn’t necessary
