count 1 for ReadHoldingRegisters ist not working

[StefanGrogg]

Hi
Im using VisualStudio FluentModbus-Nuget V5.3.2. I'm trying to use ReadHoldingRegisters. If i read a count of 2 registers, all work fine. But sometimes i need to read only 1 register, bit cout of 1 is not working. In this case, i also don't get any error. Just the method will not finish.

Thanks for any help.

你读取的数据类型是？
如果你读取的是 byte
即 client.ReadHoldingRegisters<byte>(unitIdentifier, 10, 1)
这样是错误的，因为在 FC03 ，一个寄存器是占用2个byte,所以如果你是读取的byte，长度必须是2的整数倍

如果读取的是其它数据类型（比如 short int 等）
我测试下来是可以正常读取的
