威纶通cMT X系列触摸屏外部变量如何转换为内部变量

请教各位：1. 欧姆龙NJ系列PLC与威纶通cMT X系列触摸屏采用以太网通讯；2. 威纶通cMT X系列触摸屏与三菱E800系列变频器进行modbus通讯；3. 物料连接均以正常。请问：PLC中计算的频率值如何写入到变频器中？

资料传输就行

资料传输就行

资料传输很不可靠，触摸屏更改一下重新下载，数据传输就断了，再下载的时候有数据传输又正常了。
用宏指令做一下数据转化就能实现。但是奇怪的是之前用三菱Q系列PLC就一切正常，现在另一个项目中用欧姆龙NJ系列PLC就不行，外部变量的数据无法转化过来。

以下这段宏指令运行OK;

macro_command main()
//Modbus 读取传递到PLC
short a=0
GetData(a, "MODBUS RTU (Adjustable)", 4x, 2#0, 1)
SetData(a, "Mitsubishi MELSEC-Q/L - Binary Mode", D, 2204, 1)   //CH1 实际值传递到D2204

short b=0
GetData(b, "MODBUS RTU (Adjustable)", 4x, 2#1, 1)
SetData(b, "Mitsubishi MELSEC-Q/L - Binary Mode", D, 2206, 1)   //CH2 实际值传递到D2206

short c=0
GetData(c, "MODBUS RTU (Adjustable)", 4x, 2#2, 1)
SetData(c, "Mitsubishi MELSEC-Q/L - Binary Mode", D, 2208, 1)   //CH3 实际值传递到D2208

short d=0
GetData(d, "MODBUS RTU (Adjustable)", 4x, 2#3, 1)
SetData(d, "Mitsubishi MELSEC-Q/L - Binary Mode", D, 2210, 1)   //CH4 实际值传递到D2210

short e=0
GetData(e, "MODBUS RTU (Adjustable)", 4x, 2#4, 1)
SetData(e, "Mitsubishi MELSEC-Q/L - Binary Mode", D, 2212, 1)   //CH5 实际值传递到D2212

short f=0
GetData(f, "MODBUS RTU (Adjustable)", 4x, 2#5, 1)
SetData(f, "Mitsubishi MELSEC-Q/L - Binary Mode", D, 2214, 1)   //CH6 实际值传递到D2214

short g=0
GetData(g, "MODBUS RTU (Adjustable)", 4x, 2#6, 1)
SetData(g, "Mitsubishi MELSEC-Q/L - Binary Mode", D, 2216, 1)   //CH7 实际值传递到D2214

short h=0
GetData(h, "MODBUS RTU (Adjustable)", 4x, 2#7, 1)
SetData(h, "Mitsubishi MELSEC-Q/L - Binary Mode", D, 2218, 1)   //CH8 实际值传递到D2218
