Remedies for WDT errors on a MELSECNET/H board
The MELSECNET/H utility notifies that an error has occurred on the MELSECNET/H interface board Q80BD-J71LP21-25 and the error code is -28158 (9202H). What is the error and how can I prevent the error?

Answer
The error code indicates a WDT (watchdog timer) error. It is determined as the cause that the MELSECNET/H driver cannot work due to a computer or OS hang, or the control was not transferred to the MELSECNET/H driver in the WDT timeout period because the processing of another driver had been performed by the CPU.
As a remedy, check if there are personal computer system errors and solve the problems if there are.
Alternatively, adjust "Driver WDT Monitoring Time" in the "Driver" window of the MNETH utility.
