#1
Whether the previous output value is retained or the current value is output depends on the timing at which an error occurred.
#2
An attempt to write output data failed for all DO channels (that is, the previous value is retained).
#3
Data of the current value is output for all DO channels.
#4
In the case of a fixed error that is not transient, the message is output each time the user accesses the device. A library function
immediately returns without waiting for I/O of the device. Therefore, make sure that continuous operation without waiting time
does not result in sequential output of error messages or a high load on the CPU.
