通道定义 — 支持多个 TCP 或 RTU 通道
|
||
每个通道独立连接参数，通道之间互不影响
|
||
|
||
参数说明:
|
||
id — 通道唯一标识 (0~N)
|
||
mode — "tcp" 或 "rtu"
|
||
host — TCP 目标 IP
|
||
port — TCP 目标端口 (默认 502)
|
||
device — RTU 串口设备路径
|
||
baud — RTU 波特率
|
||
parity — RTU 校验位 (N/E/O)
|
||
data_bit — RTU 数据位
|
||
stop_bit — RTU 停止位
|
||
timeout_ms — 请求超时 (ms)
|
||
retry_cnt — 失败重试次数
|

点表定义
|
||
|
||
通用属性:
|
||
no — 信号序号 (全局唯一)
|
||
type — 数据类型: 2=bit(开关量), 4=uint16, 6=float32, 7=uint32, 13=string
|
||
channel — 归属通道 ID (对应上方 Channel id)
|
||
slave — 从站地址 (1~247)
|
||
fc — Modbus 功能码:
|
||
0x01=读线圈, 0x02=读离散输入,
|
||
0x03=读保持寄存器, 0x04=读输入寄存器,
|
||
0x05=写单线圈, 0x06=写单寄存器
|
||
0x0F=写多线圈, 0x10=写多寄存器
|
||
addr — 寄存器/线圈起始地址 (0-based)
|
||
count — 连续读取数量
|
||
bit — 位位置 (0~15), 仅当 type=2 且 fc=03/04 时有效
|
||
factor — 遥测系数
|
||
offset — 遥测偏移
|
||
saddr — 内部信号地址 (数据中心关联用)
|
||
desc — 中文描述
|
||
|
||
重要: FC03/04 + type=2 表示"从寄存器中提取线圈值"，
|
||
即一个寄存器的 16 个 bit 对应 16 个线圈。
|
||
bit 属性指定提取哪个位 (0~15)。
