Settimino Connection to S7-1200 via IoT2040

Hello,

We understand you're encountering connection issues between Settimino and your S7-1200 PLC through the IoT2040. While direct success stories with this specific configuration are not widely documented in our knowledge base, here are potential causes and troubleshooting steps:

• Firewall Issues: Ensure the IoT2040 and the S7-1200 are not blocked by firewalls.
• Network Configuration: Double-check the network settings on all devices (IoT2040, S7-1200, and your PC). Verify subnet masks and gateway settings.
• S7 Connection Parameters: Even if seemingly correct, re-verify the PLC's MAC address, IP address, Rack number (usually 0), and Slot number (usually 1) within Settimino.
• Settimino Configuration: Review Settimino's configuration file for any conflicting settings or limitations.
• TSAP Settings: In some cases, specific TSAP (Transport Service Access Point) settings may be required. Consult Settimino documentation.
