我厂DCS用的是HONEYWELL TPS系统,ESD用的是ICS的trusted系统，两者之间采用MODBUS协议，我想将DCS中的DI点通讯到ESD，用了N种方法也未成功，特此求助各位大大。

看一下modbus协议，霍尼写DI到ESD。

你说的系统我没有用过，不过通讯应该是没有问题的。关键就是地址和类型对吗？

如果软件没有问题，加个隔离器看看。

加一块SI卡，然后做一些组态，很简单

你可以把开关量点通过LOGIC点强制写进ARRAY点就可以通过ARRAY点通过MODBUS协议写到ESD里了，应该很简单。如果有OPC接口的话你也可以通过OPC，通讯更迅速

DCS 可以直接读写 ESD 里的整型或者开关量（定义可读写区域内的）

1）ICS 可以定义在整型40001以后的一个整型 16位，然后DCS对16位的每个位做操作 0 OR 1 ,ESD 再 拆分这个整型读起每个位的数值。

2）ICS 可以定义在开关量1开始的 之可以读写的开关量，可以直接定义一些内部变量BOOL 进行通讯。

注：HW 与 ICS 通讯建议波特率 9600 然后通讯整型 16位。
