| 模式 | 功能码 | 典型用途 |
|---|---|---|
| Normal Modbus Slave | Standard Modbus RTU operation using a software-configured slave ID from 1 to 247. | Central PLC, RTU, IPC or SCADA monitoring and control. |
| Hardware Logic Gates | Per-output input masks support AND, OR, XOR, NAND, NOR and XNOR relationships. | Local interlocks and deterministic field actions independent of routine host polling. |
| Pattern Matching | Detects a configured 8-bit input pattern with optional polarity inversion for each input. | Machine-state recognition and compact interlock conditions. |
| Programmable Sequencer | Linear or pendulum sequences with channel mask, step interval, pulse width, inter-sequence delay and repeat control. | Valve sequencing, backwash cycles and repetitive machine actions. |
| Alarm Annunciator | Selected inputs drive steady or blinking outputs using active-high or active-low logic and a configurable flash interval. | Local panels, stack lights, sirens and machine alarm functions. |
| PWM / PID Control | Per-channel PWM includes frequency, duty, ramping, hold, minimum and maximum intensity; supported modes add smoothing, noise tolerance and PID auto-tune. | Time-proportional loads, controlled intensity and supported closed-loop applications. |
| Frequency Simulator | Generates triangle, sawtooth, square or sine frequency patterns between configured limits. | Simulation, test and controlled frequency-output applications. |
| Safe-State Controller | Programs every output for power-up and communications-loss conditions. | Deterministic recovery and network-failure behaviour. |
