Upgrading from a SR30-M2-D1, SR20-D2, or SR15-D1 #pyranometer to our latest models SR300-D1, SR200-D1, or SR100-D1? New instruments can now emulate all commonly used legacy #Modbus registers for a drop-in replacement experience! https://t.co/ErpfbBWYUF

10 minutes of passive listening on an OT network. Every IP. Every protocol. Every Modbus register polled. Every device link. No packets sent. No alerts. No logs. OT protocols are cleartext. Listening tells you everything. 🧵 #OTPentesting #Reconnaissance #OTSecurity #Modbus

Wireshark baseline: OpenPLC ↔ Kali, Modbus TCP. FC3 (Read) every ~1s. FC16 (Write): zero during normal operation. FC16 from an unexpected IP, that's your alert. Most OT teams skip the baseline. They regret it during the incident. #OTSecurity #Modbus #Wireshark #OpenPLC

Writing a register to OpenPLC from Kali: Same as FrostyGoop sent ENCO controllers in Lviv. No credentials. No session. No handshake. Python + port 502. Modbus segmentation isn't optional. #OTSecurity #Modbus #FrostyGoop #OpenPLC

600 apartment buildings lost heating in Lviv, Ukraine. Sub-zero January, 2024. No exploits. No zero-days. No backdoor. Just Modbus TCP function codes sent to port 502. FrostyGoop proved the protocol itself is the weapon. 🧵 #FrostyGoop #Sandworm #Modbus #OTSecurity

Every 4-20mA sensor needs its own analog input card. Cards are expensive. Racks fill up fast. DR3451 RS485 daisy-chain puts 247 sensors on one PLC port. Save cost, space, and complexity. What's your take? #RS485 #Modbus 🔗 https://t.co/QjDBBvKnEB

I'm back to redesign an old project. For fun. On #STM #FreeRTOS I've created a #modbus slave. Now I can control the triac timing with #Qt app.

Modbus speed explained: Think of baud rate like internet speed. Higher means faster data, but Modbus has limits. It's not the internet, it's industrial communication. #Modbus #TechExplained
