[Introduction]：The M31 series distributed IO host supports Modbus TCP and RTU protocols, allows up to 5 clients to access simultaneously, and is compatible with function codes 01, 02, 03, 04, 05, 06, 15, and 16. The shell adopts three-proof coating, which is Anti-Fungal, Anti-Humidity, and Anti-Salt Spray. This reduces costs while facilitating easy integration into existing site environments. The device includes built-in status diagnostics for real-time monitoring of IO module communication status.
