1️⃣ 🎯 Functional Purpose

The Squid-5N-client is designed for:

• 📡 collecting and transmitting data from connected sensors and devices over GSM/Internet networks;
• 📥 receiving commands from SCADA systems via mobile Internet using the Modbus RTU protocol;
• 🔄 enabling two-way data exchange for monitoring and controlling remote facilities;
• 🛡 establishing a secure and stable communication channel between field equipment and the dispatching center.

Thus, the Squid-5N-client serves as a remote node in dispatching and telemetry systems.

2️⃣ 🔧 Functional Capabilities

• 📊 Data acquisition from connected sensors (temperature, pressure, level, digital input states).
• 🔗 Support for communication protocol – Modbus RTU.
• 📤 Data transmission to the server via GPRS/3G/4G.
• 📥 Receiving control commands from the central system via mobile Internet.
• ⚡ Control of output channels (equipment switching on/off, relay control).
• 🗄 Local data archiving with deferred transmission after connection recovery.
• 🛡 Fault tolerance – data buffering and automatic restoration after network failure.
• 🔑 Option for encrypted communication channel to ensure secure data transmission.
