/**
 * PLC 焊接参数定时读取测试。
 *
 * 每 3 秒读取一次 A/B 工位的焊接参数（电压、电流、送丝速度、job号）并打印到控制台。
 *
 * 焊接参数点位（参考 PlcUtil.getParamDyDl）：
 *   A 面：电压 DB1010.2 (Float32)、电流 DB1010.8 (Float32)、送丝速度 DB1010.14 (Float32)、job号 DB1010.20 (Int16)
 *   B 面：电压 DB1010.26 (Float32)、电流 DB1010.34 (Float32)、送丝速度 DB1010.42 (Float32)、job号 DB1010.48 (Int16)
 *
 * 运行：直接运行 main 方法即可，按 Ctrl+C 退出。
