7811R 160-channel DIO can be configured separately？7811R 160路DIO是否可以单独配置

[zhenyang]

The user manual describes that the DIOs of the 7811R and 7830R are slightly different, does it mean that the DIO of the 7811R cannot be individually configured as an input or output port?

It is also found in actual use that, for example, when DIO1 has been configured to output high, and when DIO2 is configured to output high separately, the output state of DIO1 will change from high to low.

用户手册上描述7811R和7830R的DIO略有差别，是不是意味着7811R的DIO无法单独配置为输入或输出口？

实际使用时也发现，比如DIO1已经配置成为输出高，再单独配置DIO2输出高时，DIO1的输出状态会从高变为低。
