Industrial Safety introduction of Modbus (reprint)

. Through testing, we believe that this phenomenon may be caused by the internal logic of the device. To turn off automatic mode, a specific light needs to be turned on first. We use the Write command to invert the values of all registers, except%MW3. %MW3 is retained because the%MW3 maps to a flashing button on the HMI, regardless of the state of the other registers, all LEDs will blink as long as the%MW3 is placed. After completing the above steps, setting the%MW4 to zero will disable the sett

avoids man-in-the-middle (mitm) attacks. Currently, both SSH1 and SSH2 versions support this security authentication method. The latter security authentication method is complicated. Therefore, it may take a long time for a user to log on to the server. Sometimes it may take even one minute or longer. When you start the first session, there will be a "." prompt on the client before the SSH user authentication prompt appears. Generally, this prompt do
