关于用PCI1670数据采集卡控制F18电桥的问题

原先F18电桥是用艾讯公司的AX5488采集卡控制的，初始化设置如下（GPIB地址为4）：
Addr1 = 4
Flag = ibinit((2 * 16 ^ 2 + 14 * 16 + 1), 21, 256)
Cmd$ = "ONL"
Flag = ibwrt(Addr1, Cmd$, Len(Cmd$))
Cmd$ = "AU"
Flag = ibwrt(Addr1, Cmd$, Len(Cmd$))
Cmd$ = "SRC2"
Flag = ibwrt(Addr1, Cmd$, Len(Cmd$))
Cmd$ = "G1"
Flag = ibwrt(Addr1, Cmd$, Len(Cmd$))
Cmd$ = "C3"
Flag = ibwrt(Addr1, Cmd$, Len(Cmd$))
Cmd$ = "FRQ1"
Flag = ibwrt(Addr1, Cmd$, Len(Cmd$))
Cmd$ = "CHK0"
Flag = ibwrt(Addr1, Cmd$, Len(Cmd$))
Cmd$ = "MET0"
Flag = ibwrt(Addr1, Cmd$, Len(Cmd$))
Cmd$ = "B0"
Flag = ibwrt(Addr1, Cmd$, Len(Cmd$))
执行后，F18成功响应。
现在换用研华工控的PCI1670采集卡控制，所要执行的操作还是初始化设置，只是语句的格式改了，如下：
Bridge_add = 4
Dev2% = ildev(0, Bridge_add, 0, T3s, 1, 0)
      
cmd$ = "ONL"
ilwrt Dev2%, cmd$, Len(cmd$)
   
cmd$ = "AU"
ilwrt Dev2%, cmd$, Len(cmd$)

cmd$ = "FRQ1"
ilwrt Dev2%, cmd$, Len(cmd$)
   
cmd$ = "C3"
ilwrt Dev2%, cmd$, Len(cmd$)

cmd$ = "G1"
ilwrt Dev2%, cmd$, Len(cmd$)

cmd$ = "SRC2"
ilwrt Dev2%, cmd$, Len(cmd$)

cmd$ = "CHK0"
ilwrt Dev2%, cmd$, Len(cmd$)

cmd$ = "MET0"
ilwrt Dev2%, cmd$, Len(cmd$)

cmd$ = "B0"
ilwrt Dev2%, cmd$, Len(cmd$)

结果F18却没有响应，请教高人这是有什么问题
万分感谢！！

你是用厂家的DLL包吗？反正都有使用说明..

厂家的dll包？我看原来成功的F18的vb程序里面，有一个Module1.bas
我问了一下别人，可能是F18和PCI1670的兼容性问题
