宏指令 问题

GetData(d5,"MODBUS RTU",4X,5,1)     //值为 0
GetData(d6,"MODBUS RTU",4X,6,1)     //值为 49
GetData(d7,"MODBUS RTU",4X,7,1)     //值为 979
zl=d5*65535+d6+d7*0.001

GetData(dm10, "Mitsubishi FX2N", M, 10, 1)
GetData(dm11, "Mitsubishi FX2N", M, 11, 1)
GetData(dm11, "Mitsubishi FX2N", M, 12, 1)

SetData(zl,"Local HMI",lW,0,1)                //原件 显示 为0   异常


set语句位置移动下就正常了

GetData(d5,"MODBUS RTU",4X,5,1)     //值为 0
GetData(d6,"MODBUS RTU",4X,6,1)     //值为 49
GetData(d7,"MODBUS RTU",4X,7,1)     //值为 979
zl=d5*65535+d6+d7*0.001

SetData(zl,"Local HMI",lW,0,1)            //原件显示为   49.979   正常

GetData(dm10, "Mitsubishi FX2N", M, 10, 1)
GetData(dm11, "Mitsubishi FX2N", M, 11, 1)
GetData(dm11, "Mitsubishi FX2N", M, 12, 1)


变量和 setdata 之间不能有其他的getdata  语句么。
