IReadWriteMcEnableWriteBitToWordRegister 属性 |
是否开启支持写入位到字寄存器的功能，该功能先读取字寄存器的字数据，然后修改其中的位，再写入回去，可能存在脏数据的风险
Whether to enable supporting the function of writing bit-to-word registers, which first reads the word data of the word register, then modifies the bits in it, and then writes back, there may be a risk of dirty data

命名空间： HslCommunication.Profinet.Melsec.Helper
程序集： HslCommunication (在 HslCommunication.dll 中) 版本：12.1.2.0 (12.1.2.0)
语法备注
关于脏数据风险：从读取数据，修改位，再次写入数据时，大概需要经过3ms~10ms不等的时间，如果此期间内PLC修改了该字寄存器的其他位，再次写入数据时会恢复该点位的数据到读取时的初始值，可能引发设备故障，请谨慎开启此功能。
About dirty data risk: from reading data, modifying bits, writing data again, it takes about 3ms ~ 10ms to pass a time, if the PLC modifies other bits of the word register during this period, when writing data again, it will restore the data at the point to the initial value when reading, which may cause equipment failure, please turn on this function carefully.
